Metal lath suspensions arecommonly made belowvirtually all types of construction for fire-ratedand non fire-rated plasterceilings. Framing of 1 1/2"C.R. channels are spacedup to 4' o.c. perpendicularto joists and are cross-furred with 3/4" C.R. channels spaced accordingto specifications for typesand weight of metal lath.Lath is then properlylapped at sides and endsand tied every 6" to the 3/4" channel.

Where it is advisable to installunrestrained ceilings, having perimeters separated from adjacentwalls or partitions, galvanized casing beads

should be installed aroundthe periphery.

Metal Lath is frequently usedfor furred as well as suspended ceilings.

Metal lath is used for furringfrom wood, concrete andsteel joists.

RECOMMENDATIONS1. Control joints should be

installed in ceilings withoutperimeter relief with a max-imum distance betweensuch joints of 30' with amaximum undivided areaof 900 sq. ft. With perime-ter relief, maximum dis-tance is 50' with maximumundivided area of 2500sq.ft.

2. Use three-coat plastering onmetal lath.

NATIONAL GYPSUM COMPANY

National Gypsum’s ownpatented Calcidyne systemheats the land plaster toremove 75% of the waterwhich is chemically combinedin the gypsum molecules.

National testing organizations frequently participate in themany product tests conducted at National Gypsum’s ResearchCenter. The Research Center’s fire, acoustical, structural andanalytical test laboratories are available commercially throughNGC Testing ServicesSM for other manufacturers and researchinterests. For information, call 716-873-9750.

YOUR TECHNICALRESOURCEToday, more than ever, clear,

accurate information is vitalto every construction job.The challenges of construc-tion continue to grow:increasingly innovativebuilding designs, tighterbudgets, tighter schedules,and the continuing devel-opment of new materialsand construction tech-niques.

A NETWORK OFTECHNICAL SUPPORTIn keeping with the corporate

mission to become the pre-ferred supplier for our cus-tomers, National Gypsumhas made a total commit-ment to technical assis-tance and created a net-work of support to providevaluable assistance at everystage of a project’s devel-opment.

Field Representation. Beforeconstruction begins, whileplans and specifications arebeing produced, theseexperienced, trained pro-fessionals provide technical consultation in selecting, specifying and using gypsum-based building materials.During the constructionphase, our FieldRepresentatives have theexperience and the trainingto assure that the National

Gypsum products you needand specify are right for the job. They are backedup by thoroughly trainedCustomer ServiceRepresentatives who canalso help with productselection and purchase.

Continuing Research. Becausethe building industry andbuilding codes are con-stantly changing, NationalGypsum maintains a full-scale research center thatcontinually tests and evalu-ates products, applications,construction systems andtechniques.

Immediate Answers. Ofcourse, there are timeswhen you need an answerto a pressing situation orquestion. For this reason,National Gypsum has setup our TechnicalAssistance Hotline: 1-800-NATIONAL (1-800-628-4662).

QUALITY IS SYSTEMATICAt the National Gypsum

Research Center, we concentrate not only onbuilding products individu-ally but also on completeconstruction systems. In

such systems, prod-ucts are evaluatedtogether as com-plete buildingassemblies – walls,partitions, floorsand ceilings.

Before NationalGypsum releases asystem to the build-ing industry, the sys-tem is thoroughlytested and theresults are correlat-ed and charted,making it easier forthe builder or archi-tect to match a sys-tem to his needs orto building codes.This extensive data-base of technicalinformation is madeavailable to you notonly through techni-cal bulletins such asthis one, but alsothrough our techni-cal support network.

The construction systemsreferred to in this manualare designed and testedwith material manufactured by National Gypsum.Substitutions of other products or brands forNational Gypsum Productsare not recommended.

Field Installation of tested sys-tems must be identical tothe laboratory installationto produce optimum per-formance of these systems,though duplication of con-trolled, laboratory resultsin such field installations isnot guaranteed.

Performance tests are conducted according toaccepted national stan-dards under controlled lab-oratory conditions to mini-mize variances and to per-mit comparison of testresults of all types of sys-tems, similar and dissimilar.

Detailed recommendationsare contained in each sec-tion. Architects, structuralengineers or others whoare responsible for fieldinstallations must maketheir own determinationsconcerning the applicabili-ty of the laboratory perfor-mance test results to thedesign or construction ofany specific structure.

National Gypsum’s Technology Innovation Center is located inCharlotte, North Carolina. National Gypsum has always held a leader-ship role in the development of gypsum based products and systems.Many of today’s most innovative gypsum, joint treatment and cementboard products and systems were developed, tested and introduced byNational Gypsum Company.

8 NATIONAL GYPSUM SOUND AND FIRE RATED ASSEMBLIES

Sound and Fire Rated Assemblies

SOUND RATINGSDrywall and plaster construc-

tion systems are laboratorytested to establish theirsound insulation character-istics. Airborne sound insu-lation is reported as theSound Transmission Class(STC), whereas impactnoise, tested on floor-ceil-ing systems only, is report-ed as the Impact InsulationClass (IIC).

When selecting systems basedon laboratory performanceratings, it should be clearlyunderstood that field condi-tions such as flankingpaths, air leaks, etc. causedby design or workmanshipcan reduce acoustical per-formance. For these rea-sons National GypsumCompany cannot guaranteethe performance ratings of specific constructionassemblies erected in the field.

To achieve maximum soundisolation from an assembly,published constructiondetails must be followedcompletely. The use ofnon-hardening, permanent,resilient, acoustical sealantis recommended to seal offair leaks at floor, ceiling,and partition or wall inter-sections.

In selecting a construction sys-tem where sound isolationis important it is necessaryto take into account thebuilding’s overall structuraldesign, openings, type ofoccupancy, location andbackground noise level.The complexity of the pro-posed system will necessar-ily affect the final cost andpossibly the in-placeacoustical performance ofthe system.

The national standard for air-borne sound testing, ASTME 90, measures the soundtransmission loss from 125to 4,000 Hertz. It is mea-sured at 16 one-thirdoctave frequencies. Thedata measured in ASTM E 90 is then fitted to theSTC curve as is specified inASTM E 413. The STCshould not be comparedwith FSTC values that areobtained from field soundtransmission loss tests fol-lowing ASTM E 336 proce-dures. The method used todetermine FSTC ratings isdifferent and cannot be

related to STC ratingsachieved by ASTM MethodE 90.

FIRE RESISTANCE The term “fire-resistance”

designates the ability of alaboratory-constructedassembly to contain a firein a carefully controlled testsetting for a specified peri-od of time. Such an assem-bly might be a partition, afloor/ceiling, a roof/ceiling,or a protected beam or col-umn. The degree thatassemblies put together andtested under controlled lab-oratory conditions retardthe spread of damagingheat is measured in inter-vals of time. For example, ifa construction assembly inthe laboratory adequatelycontains the heat for twohours and meets otherrequirements during thelaboratory fire test, it isgiven a two-hour fire resis-tance rating.

Fire tests may be conducted atany of several recognizedfacilities. Partitions,floor/ceilings, roof/ceilings,beams and columns aretested in accordance withASTM Standard E 119, FireTests of Building andConstruction Materials.Fire-resistance ratings arebased on full-scale testsunder controlled conditionsand are generally recog-nized by building codeauthorities and fire insur-ance rating bureaus.

Requirements for fire-resis-tance ratings are usuallyassigned by local buildingcode officials based on theexpected occupancy of thespace. It is critical that youreview plans in the bidstage to ensure that thedetails drawn match thereferenced design numbers.If the detail drawn does notmatch the assembly designnumber as listed in theGypsum Association FireResistance Design Manual,UL Fire ResistanceDirectory, or FactoryMututal SpecificationTested Products Guide,contact the architect for aclarification.

Fire-resistant ratings representthe results of controlledlaboratory tests on assem-blies made of specific con-

PARTITION CONTROLJOINTSIn long expanses of partitions

such as corridors, controljoints should be used atleast every 30'. Door andwindow openings createstress points in partitionsand are recommendedlocations for control joints.Where jambs extend fromfloor to ceiling and arespaced not farther apartthan 30', no control jointsare required. When“through-wall” controljoints are required in firerated assemblies, specialdetails are necessary whichare shown on page 92.They are based onWarnock-Hersey ReportWHI 651-0318.1.

CEILING CONTROL JOINTSFor large expanses of ceilings

with perimeter relief, control joints must belocated a maximum of 50'o.c. in either direction;without perimeter relief,30' o.c. maximum in eitherdirection. Control jointsshould be installed whereframing or furring changesdirection.

PERIMETER CONTROLJOINTSAcceptable perimeter control

joints in systems do notadversely effect fire orsound ratings. The use ofperimeter control joints infire-rated assemblies isdescribed in UL Report R-4024-7-8 and FactoryMutual Report 16738.69.

figuration. For that reason,National GypsumCompany cannot guaranteethe performance of specificconstruction assemblieserected in the field. Whenselecting constructionassemblies to meet certainfire-resistance require-ments, caution must beused to insure that eachcomponent of the assemblyis the one specified in thetest. Further, precautionshould be taken that assem-bly procedure is in accor-dance with that of the test-ed assembly.

For fire safety information, go towww.nationalgypsum.com.

CONTROL JOINTS ANDISOLATION DETAILSThough most systems referred

to in this manual are non-load-bearing, they needstructural consideration oftheir ability to retainintegrity over a period oftime and be relatively rigid.When other elements suchas doors, fixtures, cabinets,etc., are affixed or joined toa drywall or plaster system,provision must be made toinsure that these loads areadequately supported.Structural framing, com-pletely separate from thesystem, may be necessaryto support eccentric orheavy loads.

CONTROL JOINTSControl joints are frequently

necessary to prevent crack-ing in the gypsum wall-board and plaster systems.Isolation should always beconsidered where structuralelements such as slabs,columns, or exterior wallscan bear directly on non-load-bearing partitions.

Gypsum as well as otherbuilding products andmaterials are subject tosome form of movementinduced by changes inmoisture or temperature, orboth. To relieve the stresseswhich occur as a result ofsuch movement, controljoints are required in bothpartitions and ceilings.

Control joints preventcracking in large areas ofgypsum wallboard.

NOTES FOR USE OF QUICK SELECTORThe construction systems shown here are representative of the

many National Gypsum Drywall partitions and ceilings systems using Gold Bond brand products that have been thesubject of controlled laboratory testing or engineering evaluations. For a given Fire Resistance Rating or SoundIsolation value, simply scan the appropriate columns. Designreferences prefixed by “Based on...” are extrapolations fromtest data on similar assemblies.

In the drawings, in steel or wood stud partitions where insulationis shown in half of the partition cavity, the insulation isrequired for sound ratings only. Where shown across full cavity, insulation is required for fire rating. Size of studs areminimum and spacing of studs are maximum for fire rating.Steel studs are 25 gauge if not specified.

In the following Quick Selector, Underwriters Laboratories, Inc.Design Numbers refer to designs contained in the UL FireResistance Directory. National Gypsum Company, Gold BondFire-Shield and Fire-Shield C products bear the ULClassification Mark and are covered by UL’s Classification and Follow-Up Service.

Gold Bond Brand GypsumSheathing is a waterresistant board productdesigned for attachment tothe outside of exterior wallframing as a water resistantunderlayment for variousexterior siding materials.The sheathing ismanufactured with a wax-treated water resistant corefaced with water repellentpaper on both face andback surfaces and on bothlong edges. Fire-Shield(type X) Jumbo Sheathinghas special additives in thecore to enhance its fireresistive properties.

USES1. As a sheathing for wood

framed residentialconstruction to provide fireresistance, weatherprotection and to add tostructural strength whenused under exterior finishessuch as vinyl siding,clapboard, paneling,masonry veneer, stuccoand shingles.

2. As a sheathing for steel studcommercial construction

and as a component incurtainwall systems andexterior insulation systemsand finishes.

3. As a sheathing for use infire-rated exterior wallassemblies.

ADVANTAGES1. Economical: Both material

and application costs arelow.

2. Fire Resistance: The non-combustible gypsum core of the sheathing helpsprotect framing elementseven when the siding orfinish material iscombustible.

3. Weather Protection:Gypsum Sheathing’smoisture resistant core andwater repellent surfacesprovide a barrier thatresists passage of wind andwater.**

4. Little or No Sawing:Gypsum Sheathing can bescored and snapped toexact size without cuttingor sawing.

SIZES AND TYPES1/2" x 2' x 8' (Regular) tongue and groove edge.1/2" x 4' x 8', 9', 10' (Jumbo) square edge.5/8" x 4' x 8', 9', 10' (Fire-Shield Jumbo) square edge.VAPOR PERMEABLEGypsum Sheathing typically has an average vapor permeance

of 20 perms (dry cup method) which allows the escape ofnormal interior created water vapor.

SURFACE BURNING CHARACTERISTICS:(FIRE HAZARD CLASSIFICATION)Both regular (2' x 8') and Jumbo (4' x 8', 9', 10') have a flame

spread of 20 when tested under ASTM E 84. Source: FactoryMutual Report No. 16738.102.

FIRE-RESISTANCE RATINGSA one-hour fire rating can be achieved for a wood framed wall

when constructed per UL Design U305 consisting of nominal2 x 4 wood studs 16” o.c. faced on the outside with 5/8" Fire-Shield Gypsum Sheathing and on the inside with 5/8" Fire-Shield Gypsum Wallboard.

A two-hour fire rating may be obtained per UL Design U302with 2 x 4 wood studs 16" o.c. with two layers of 5/8" Fire-Shield Gypsum Wallboard applied to the interior side and 1/2"regular Gypsum Sheathing, 24" wide sheets, T and G edges,faced with brick veneer on the exterior side.

One and two hour fire ratings may be obtained for a steel framedwall when constructed per UL Designs U 418 and U 425.

STRUCTURALRacking tests have been conducted for the Gypsum Association

by an independent laboratory according to ASTM E 72.Average ultimate racking load values were as follows:

Studs spaced 16" o.c., fasteners galvanized 11 gauge nails 7/16"head, 1 1/2" long for 1/2" sheathing and 1 3/4" long for 5/8",7" o.c. in the field and 4" o.c. on edges and ends for 5/8"gypsum sheathing; 8" o.c. in field and 4" o.c. on edges andends for 1/2" gypsum sheathing.

Corner Bracing – Where continuous diagonal bracing isrequired, many building codes allow the use of 4' wideboards of 1/2" gypsum sheathing applied vertically to be usedin place of 1" by 4" wood let-in bracing.

Shear Walls – Where wind or seismic forces require shear wallsto resist these lateral forces, most building codes provideallowable shear values for walls having gypsum sheathingapplied vertically to wood framing. Specific values withconstruction requirements and limitations are contained in themajor model building codes (International Building Code,National Building Code, Standard Building Code and UniformBuilding Code).

SPECIFICATION COMPLIANCEGold Bond Gypsum Sheathing is manufactured to comply with

ASTM Specification C 79/C 1396.

GYPSUM PLASTER SYSTEMS

INTRODUCTION

Lath and plaster have longbeen the industry standardfor wall construction.Gypsum plaster eliminatesthe need for joint tapingand finishing and, whenproperly applied, providesa smooth, high quality wallsurface with high resistanceto impact and abrasion. Inaddition, plaster walls resistnail pops better thanstandard wallboard.

For years, lath and plasterhave been used in bothresidential and commercialapplications to partitioninterior space and in non-load-bearing exterior wallswhere appearance anddurability are key. Plaster isalso commonly used as theboard material for radiantheating systems in ceilings.When used as a finishmaterial, plaster effectivelymasks framing componentsor mechanical service areaswhile contributing to theoverall strength of the wall.

Conventional plasterscombined with gypsum ormetal lath provide asmooth wall regardless ofthe framing alignment.When used with expandedmetal lath, conventionalplasters create amechanical bond with thelath for maximum strengthand durability.

National Gypsum plasters canalso be used ornamentallyor decoratively since theylend themselves tosculpting or casting.

HISTORYUse of gypsum plaster dates

back to 4000 B.C. whenthe Egyptians applied agypsum plaster-likesubstance to the interiorand exterior of thepyramids. BenjaminFranklin brought gypsum tothe United States in themid-1700s as a soiladditive. In the early 20thcentury, moderncontractors began usinggypsum plaster extensivelyfor both residential andcommercial construction.

GENERAL USESGypsum plasters are suitable

for all interior plasteringexcept where directlyexposed to free water orsevere moisture conditions.Plasters cannot be used inexterior applications suchas carports, soffits and openporches.

Gypsum plasters are non-combustible and act toprevent passage of intenseheat from fire for extendedperiods.

DESCRIPTION

SELECTING PLASTERSeveral types of plaster are

manufactured by NationalGypsum Company. Withthese products a greatnumber of ceilings andpartitions have beendesigned to aid thearchitect in the selection ofan assembly that will perform well inappearance, structuralability, sound isolation and fireendurance rating.

PERFORMANCEThe relative performance of

metal lath and gypsum lathwill vary with types ofconstruction used. Whenplaster on metal lath formsa membrane as in asuspended ceiling orhollow partition, it is moresubject to cracking than isplaster on gypsum lath. Onsolid partitions, metal lathis superior to gypsum lathwith respect to potentialplaster cracking.

ADVANTAGES• Gypsum plaster offers

important advantagescompared to drywallconstruction.

• It is possible to eliminatewavy walls and cornersdue to poorly alignedframing by varying theplaster thickness.

• Plaster eliminates texturedifferences between papersurface and jointcompound.

• Plaster gives a smoother,easier-to-repair wall thandrywall construction.

• Control joints should beinstalled in ceilings withoutperimeter relief with amaximum distance betweensuch joints of 30' with amaximum undivided areaof 900 sq. ft. With perimeterrelief, maximum distance is 50' with maximumundivided area of 2500 sq.ft. On side walls controljoints should be installedevery 30'.

• Where dissimilar plasterbases join, use strip-metallath with 15 lb. felt paperbetween the metal lath andunderlying base.

• Before plastering is started,lathing and furring shouldbe carefully inspected foradherence to good practicestandards and to the jobspecifications.

• Select from the suggestedspecifications thataccompany the descriptionof each system.

FIRE TEST DATAFire resistance ratings

specified by most codes are met by tests certified by Factory Mutal,Underwriters Laboratories,Inc., Warnock-HerseyInternational or otherauthorities according to the “Standard Methods of Fire Tests of BuildingConstruction & Materials”(ASTM E 119). The testinvolves subjecting aconstruction system to heat and flame in a testfurnace which is regulatedaccording to a standardtime-temperature curve.Various types of testingfurnaces are used for walland partition assemblies,floor and ceilingassemblies, columns, and similar constructionelements and assemblies.

At periodic intervals, astandard measuringprocedure is used to readtemperatures at variouslocations in the testspecimen. The test iscontinued until either thefire resistance rating soughtis obtained or failureoccurs. The Fire TestAssembly fails when it canno longer support the liveload, or when passage offlame or gases hot enoughto ignite cotton wasteoccurs, or when thetemperature transmissionexceeds the allowablelimits. The hose stream isrequired for wall andpartition tests that are ratedone hour or moreendurance time and is notrequired for floor-ceiling or

column fire tests. The hosestream is not alwaysnecessary, and is notrequired on constructionsrated less than one hour.

Published ratings listendurance periods thathave been rounded off tothe next lower hour or halfhour. Although enduranceperiods of someconstructions are longerthan four hours, time inexcess of four hours is notordinarily indicated inpublished tabulationsbecause this is themaximum period requiredby most codes.

The National Gypsum fireendurance test facility correlates with that ofUnderwriters Laboratoriesand conforms with testconditions prescribed inASTM Standard E 119.While the continued needfor independent laboratorytest data is recognized, thecompany facility providesboth preliminary andsupportive test evidence.

INTERPRETINGACOUSTICAL TEST DATAWhen selecting a partition

system to meet a specificsound insulationrequirement, it is necessaryto rely upon laboratory testdata. Through the use ofthese data obtained fromtests conducted inaccordance with standardprocedures, it is possible tominimize variancesbetween tests and toprovide a basis forcomparisons between theperformances of differentassemblies. In a continuingeffort to increase the degreeof correlation andrepeatability, ASTMperiodically reviews andrevises each test standardwhich, for airbornetransmission loss, is E 90.

Laboratory test results shouldbe used for comparisonpurposes only. Fieldperformance is extremelydifficult to predict becauseof the many variableswhich are encounteredunder field conditions. Forexample, any of thefollowing factors maycontribute to lowerperformance than obtainedin the laboratory:

1. Service outlets, telephoneboxes, other openings.

2. Continuous heating andventilating ducts.

3. Common plenums overadjacent rooms.

4. Common hollow floorsunder adjacent rooms.

5. Doors, windows.6. Cracks at perimeter of

walls, such as at floor line.Care must be taken to

minimize the detrimentaleffect of these factors ifsatisfactory performance isto be attained in the field.

STRUCTURAL RESTRAINTOF PARTITIONS Because the basic philosophy

of building design andconstruction isexperiencing change, manystructures today exhibitgreater flexuralcharacteristics thanstructures built in the past.Although these newstructures are basicallysound, they are capable ofimparting forces toelements of the buildingwhich are not intended toresist such stresses withoutcracking, spalling, tearingor other visible effectswhich are objectionable toall principles involved.

Experience has shown that thebuilding types most likelyto cause partition crackingare “flat plate” constructionand related reinforcedconcrete structures.

Analysis of flat plate structuraldesign shows that in a highrise building, structuralmovement may beattributable to, and varywith:

1. Building height.2. Building area.3. Number and location of

shear walls.4. Exposure of structural

elements to temperaturedifferentials.

5. Basic deflection criteria forstructural design.

6. Construction loads onnewly formed structuralelements.

7. Plastic flow of structuralelements composed ofcementitious material.

8. Wind loads.9. Seismic load.10. Building settlement.

One can readily see thecomplexity of themovement problem.Depending on individualbuilding conditions,geography and climate,some movement factorsmay be cumulative, andthe resulting forces cancreate havoc in non-structural portions of thebuilding.

It is not our intention to enterinto the theory or design ofconcrete structures whichis clearly the prerogative ofthe architect or engineer.However, we do feel that itis our responsibility todevelop and suggestinstallation methods toensure the satisfactoryperformance of non-load-bearing partitions withconcrete structures.Therefore, we advocateand recommend thefollowing procedures tominimize partitioncracking and achieve amore compatiblerelationship between thestructural frame andadjoining non-structuralelements withconsideration for soundand fire criteria.

These procedures andspecifications are based onwork done in thelaboratory, analysis ofbuilding types, analysis ofpartition types andexperience developed overthe years in partition work.

Laboratory tests and fieldexperience have shownthat a small amount ofrelief at the periphery of apartition or in areas wherereduction in cross sectionoccurs (doors, windows,etc.) is exceptionallyeffective in minimizing thecracking of a partition.

It is the opinion of NationalGypsum that a 1/4" controljoint provided betweenpartition and abuttingstructural elements wouldcompensate for the actualmovement in a majority ofinstances where structuraldeformation occurs.

Partition facings must beisolated from the abuttingstructural elements.

A compliant material must beused to create a closure atthis junction. This materialmay be a convenientresilient foam. In someinstallations permanentlyflexible acousticalcaulkings may have therequired properties. Ifdesired, mouldings securedin one plane only may beused to cover this junction.

If an architect or engineerdesigns a building structurewith potential movementcriteria that exceed thecapacity of the 1/4"control joint, one mayspecify whatever amount of partition relief desired.The methods detailed canbe adapted to providecontrol joints in excess of 1/4".

Since other factors such as fireand sound control areequally important in theperformance of a partitionsystem, it is obvious thatconsideration should begiven to the effect that acontrol joint would haveon these properties. Insound transmission testconfigurations it is usuallystandard procedure tocaulk partition boundaries.

It is equally good fieldpractice to caulk partitionboundaries in order toachieve optimum soundtransmission loss ratings.Comparative tests with thetype of control jointsrecommended (withinreasonable limits up to 1/2") have shown little or no decrease in acousticalefficiency.

Fire tests described in ULReport R4024-7-8 and FM16738.69 both demonstratethat a peripheral controljoint (up to 1/2") will havelittle or no effect uponexisting fire ratings ofpartition systems.

Gold Bond Brand Two-WayHardwall Plaster is abasecoat plaster whichrequires the job siteaddition of an aggregateand water to provideworking qualities and isdesigned for interior useover all accepted plasterbases. It may be applied byhand or used throughpump/spray plasteringmachines.

ADVANTAGESControlled UniformityTwo-Way Hardwall Plaster is

set-stabilized and adjustedfor market requirementsand seasonal changes.When mixed with sand orother aggregate it hasuniform working qualitiesand excellent spread.

StrengthTwo-Way Hardwall Plaster

properly proportioned withaggregate forms a hard,durable base for the finishcoat. Its high tensile andcompressive strength resultsin increased resistance tominor structuralmovements, impacts andabrasions.

Fire ResistanceTwo-Way Hardwall Plaster is

essentially mineral incomposition and will notsupport combustion.

Specification Reference ASTM Designation C 28,

“Gypsum Plasters”.Bag Weight 100 lbs. (45.4 kg)

Gold Bond Brand Gypsolite is a lightweight gypsumbasecoat plaster mixed atthe mill with correctly sizedand proportioned perliteaggregate, requiring onlythe addition of water on thejob. It is manufactured tobe trowel-applied overgypsum or metal lath.

ADVANTAGESUniform Strength andHardnessUniformity is assured through

exact proportioning andthorough mixing of gradedperlite and gypsum plasterat the mill. Gypsoliteprovides a uniform base forthe finish coat.

LightweightGypsolite weighs less than

half as much as sandedgypsum plaster, thusreducing the dead-load onframing.

High Insulating ValueGypsolite has a “k” factor of

1.5 which provides about 3 1/2 times the insulatingvalue of sanded plaster.

LIMITATIONSWhen used over metal lath, a

sand float finish should bespecified. A smooth-trowelfinish is not recommendedsince the combination of arelatively soft (perliteaggregated) basecoat and ahard (smooth-trowellime/gauging) finish has thepotential for cracking andspalling of the finish coat.

Fire ResistanceGypsolite has excellent fire-

resistive qualities andgenerally provides fireratings higher than sandedplaster.

PAINTING PLASTERVarious job conditions such as suction differences, wet or only

partially dry walls, and reactions between paint and lime havecaused unsatisfactory paint finishes, particularly on new construction.

Alkali-resistant primers specifically formulated for use over newplaster will permit decorating with oil or latex type paints.

Quality paint products should be used and manufacturers’recommendations followed. Finished plaster should bepainted or covered to conceal possible discoloration. Thepaint system should be suitable for use over plaster surfacesthat contain lime.

It is essential that plaster be sound and completely dry beforepainting. Conventional plaster may require 30 to 60 days tofully dry.

The systemconsists of three metal units(channel stud, metal lath, L runners) which are usedtogether with DiamondMetal Lath and GypsumPlaster. These componentsform a space-saving, strong,non-load-bearing partitionfor use in interior wallconstruction.

ADVANTAGESSpace SavingOccupies less than half the

space of conventionalwood-stud or masonryconstructed partitions.

Cost SavingSimple erection cuts labor

costs. One mechanic canquickly erect the channelstuds and tie on DiamondMesh Metal Lath.

Fire ProtectionComposed of gypsum plaster

and steel, it makes anexcellent fire barrier.Official tests give thepartition a one- to two-hourfire rating.

Sound InsulationPartition is an effective sound

barrier and has a SoundTransmission Class of 37for 2" thick with sand, 33for 2 1/2" thick with perliteaggregate.

StrengthThe completed partition is a

monolithic slab of gypsumplaster thoroughlyreinforced with expandedmetal lath and securelyanchored to floor andceiling. It is highly resistantto tension, impact, shearand vibration.

AdaptabilityPartitions will accommodate

door bucks of varioustypes, casings, switch boxesand electrical outlets; alsosupport lightweight fixturessuch as kitchen cabinets.

To simplify the installation ofpiping and ductwork and to reduce the transmissionof room-to-room noise,National Gypsum designedthe Hollow Wall System.

In the Hollow Wall System,two strong metal lath and plaster partitions areconstructed independently,without obstructions, ties or bridging.

MATERIALS1. L Runner: For floor and

ceiling.2. Channel Studs: Shall be

3/4" Cold Rolled Channels.3. Metal Lath: Shall be

Diamond Mesh, 1/8" FlatRib Lath, 3/8" Rib Lath.

ADVANTAGESThe many benefits and

possible savings availablewith the use of the HollowWall System are inherent inthe nature of the partitionsystem itself.

Obstruction-FreeThe clear, unobstructed space

between partitions providesfor pipes, ducts, conduits.No cutting, fitting or costlyadjustments are needed toaccommodate vertical orhorizontal runs of piping or ductwork.

FlexibleBecause partition halves are

separate units, they may bespaced whatever distanceapart is necessary toconceal the fittings to beinstalled. The system maybe used to build partitions

up to 8' high. If higherpartitions are required, use1 1/2" C.R. channel studs to build a maximum of 10' high.

EconomicalThe three integrated metal

parts are quickly and easilyinstalled, permittingminimum labor costs forthis type of construction.The completed partitiongenerally costsconsiderably less thanmasonry walls of the samethickness. No matter whatthe spacing betweenpartitions, the cost remainsthe same.

StrengthHollow Walls are highly

resistant to impact,vibration and cracking.Properly installed pipingand ductwork are not in

contact with partitions, andare surrounded with an airspace to permit contractionand expansion withoutaffecting the plaster.

AdaptabilityBecause it is ideal for use in

concealing piping and forresistance to soundtransmission, the HollowWall System is useful in alltypes of structures whereductwork or plumbingshould be hidden. Itaccommodates all types ofelectrical fixtures, casings,electrical switches andoutlet boxes.

LIMITATIONSThe Hollow Wall System is

practical for use only wherethe concealment of utilities is necessary.

Metal lath suspensions arecommonly made belowvirtually all types of construction for fire-ratedand non fire-rated plasterceilings. Framing of 1 1/2"C.R. channels are spacedup to 4' o.c. perpendicularto joists and are cross-furred with 3/4" C.R. channels spaced accordingto specifications for typesand weight of metal lath.Lath is then properlylapped at sides and endsand tied every 6" to the 3/4" channel.

Where it is advisable to installunrestrained ceilings, having perimeters separated from adjacentwalls or partitions, galvanized casing beads

should be installed aroundthe periphery.

Metal Lath is frequently usedfor furred as well as suspended ceilings.

Metal lath is used for furringfrom wood, concrete andsteel joists.

RECOMMENDATIONS1. Control joints should be

installed in ceilings withoutperimeter relief with a max-imum distance betweensuch joints of 30' with amaximum undivided areaof 900 sq. ft. With perime-ter relief, maximum dis-tance is 50' with maximumundivided area of 2500sq.ft.

2. Use three-coat plastering onmetal lath.

(1-800-628-4662)

BASECOAT PLASTER PROCEDURESTwo-Coat WorkApply first coat with firm pressure to form good bond on the

gypsum lath or masonry base; then immediately double back(without cross-raking first coat) using material of same proportion to build proper basecoat thickness. Straighten to a true surface (without applying water) to receive the second (finish) coat.

Surface should be left sufficiently rough and porous to providesuitable bond of the finish coat.

Three-Coat Work“Scratch” – “brown” – finish is generally used for metal lath or

masonry bases, and is performed in discrete steps.• Scratch (first) coat: Should be applied with sufficient

material and pressure to obtain good bond over solidbases or form full keys through metal lath. Provide suitable material thickness for scratching (raking) toobtain good mechanical keying of the “brown” coat.

• Brown (second) coat: Shall be applied after the scratch(first) coat has set hard. Apply to give mass and surfaceas for double-back in two-coat work.

Finish coat Plaster ProceduresGeneral Requirements (Basecoat Condition)Application over a partially dry basecoat is preferred. If basecoat

is thoroughly dry, wet with even application of water to asemi-dry condition. Avoid excess water. Do not apply finish to basecoats having free water on the surface.

Application – Gauged Lime Putty Trowel FinishSmooth Finishes

• Scratch in tightly over the basecoat, covering the surface completely, then double back immediately with material from the same gauge, filling out to a true, even surface with total thickness of not more than 1/16".

• Allow finish to “draw” (lose moisture to basecoat andambient air) and firm up – then trowel it well to compact and close the surface under the edge of thetrowel. Dash water on the surface for lubrication anddevelopment of soft material along trowel’s edge to fillsurface depressions or other blemishes.

• When finish plaster setting action is under way, a second (final) water trowelling can be done with strongpressure to obtain a polished surface if desired.

Texture Finishes• Apply finish as above to a true, even surface with total

thickness not more than 1/8".• Allow finish to “draw” (lose moisture to basecoat and

ambient air). Then begin floating, texturing, or skiptrowelling to achieve desired texture. Additions of clean graded silica may be required to achieve desired texture.

DryingConventional plaster systems should be allowed to dry30 days minimum under ambient conditions prior tofinishing. Variances in humidity or poor drying conditions may affect the drying process.

StorageGypsum plaster must be kept dry before use. Storage conditions vary with location and seasonal changes, which may affect storage life. These conditions may affect product characteristicssuch as setting time, working qualities, component separation, or lumping, etc. Such aging is normally a function of exposure to humid air, temperature, and physical support in warehousing. Adverse storageconditions or prolonged storage may effect the workingqualities of the product. Rotate inventory frequently forbest results.

VENEER PLASTER SYSTEMS

DESCRIPTION

Kal-Kore boards are screwed to steel studs or nailed orscrewed to wood studs toform a base.

Veneer plasterexpands architecturaldesign limits as withthis curved vaultedceiling.

Joints are reinforced with Kal-Mesh fiberglass webbing.Steel corner and casing beadsprotect corners.

Kal-Kote is applied in 2 coats, a base and a finish, to form a hard-surfaced, 1/8" total thickness.

Veneer Plaster Systems consistof a 4' wide gypsumplastering base with aspecial, highly absorptivepaper surface that iscovered with thinlytroweled, special purposeplasters. Two basic types of veneer plaster areavailable: Uni-Kal and X-KALibur, which are one-coat plaster systemproducts; and Kal-Kote, atwo-coat plaster system.The gypsum plaster base,Kal-Kore, is erected in thesame manner for bothsystems. Both veneerplaster systems can bespecified for virtually alltypes of partition andceiling constructionsincluding wood or steelframing or furring andmasonry. For bothresidential and commercialbuildings, either type ofveneer plaster systemproduces a wall more nail-pop resistant than drywalland, when properlyinstalled, more crackresistant than conventionallath and plaster.

ADVANTAGES - GENERALThe advantages of veneer

plaster over othercommonly used partitionand ceiling systemsinclude:

1. Rapid installation whichreduces overallconstruction time.

2. Appearance and surface ofconventional plaster atlower cost than regularplastering.

3. High resistance to cracking,nail-popping, impact andabrasion failure.

4. Mill-mixed plastercomponents help ensureuniform installationperformance and finishedjob quality.

ADVANTAGES - ONE-COATSYSTEM (UNI-KAL/X-KALIBUR)1. Requires only one plastering

material on the job.2. Slightly lower in-place cost

than two-coat system.3. Can be applied directly to

concrete block.4. X-KALibur is formulated

to have extended setcharacteristics beyondtraditional Uni-Kal settingtimes.

ADVANTAGES - TWO-COATSYSTEM (KAL-KOTE)1. Kal-Kote System may be

used for plaster-embeddedelectric radiant heatingcable systems.

2. Same applicationtechniques as forconventional plaster.

3. Greater crack resistancethan one-coat systems.

4. Can be applied directly toconcrete block.

LIMITATIONS1. Not recommended for

exterior use or wheresubject to weathering,direct water contact ortemperature exceeding125˚F (52˚C) for extendedperiods of time.

2. Framing spacing is limitedand partition heights arereduced in comparisonwith some standardconstructions.

3. Provides less rigidity thansimilar standard plastersystems.

4. When Uni-Kal/X-KALiburwill be applied, do notinstall Kal-Kore too far inadvance of plastering sinceUni-Kal/X-KALibur bondcan be adversely affected ifface of Kal-Kore hasbecome faded from light. IfKal-Kore has been faded,apply Kal-Kote Base Plasteror a bonding agent toobtain good bond.

5. All are designed for trowelapplication. Gold BondVeneer Plasters are notsuitable for conveyance orapplication byconventional plasteringmachines.

6. Compared to conventionalplasters, Veneer PlasterSystems are more subject tobeading (ridging) andcracking at the joints underrapid drying conditionssuch as those caused bylow humidity, hightemperature and/or highdraft exposure.

7. All provide a base overwhich paints or otherfinishes should be applied.

8. Do not use a polyethylenevapor retarder unlessstructure is ventilatedadequately duringapplication of veneerplasters.

9. A bonding agent must beapplied to monolithicconcrete prior toapplication of eithersystem.

VENEER PLASTER FORMETAL AND WOODFRAMING1. Wood Studs or Joists.

Wood members shall meetthe minimum requirementsof local building codes.Framing shall not exceedspacing shown in Table 1on page 46. Most partitionfire ratings require that Kal-Kore be applied vertically.When such ratings are notrequired, horizontalapplication may be used tominimize joints. Forceilings, application at rightangles to framing ispreferred.

2. Metal Studs. Align floorand ceiling tracks to assureplumb partition. Securetrack with appropriatefasteners at a maximum of24" o.c. Position studs intrack on specified centersby rotating into place for afriction fit. Secure studslocated adjacent to doorand window frames,partition intersections andcorners by self-drillingsheet metal screws throughboth flanges of studs andtracks or by use of steelstud clinching tool. ApplyKal-Kore vertically for mostfire ratings. When ratingsare not required, horizontalapplication may be used tominimize joints.

3. Masonry Wall Furring withScrew Furring Channel.Attach furring channelvertically spaced not toexceed spacing shown inTable 1 on page 46. Fasten

each channel with concretestub nails or appropriatefasteners through channelflanges into the masonry orconcrete. Fasteners shall bespaced on alternate flangesnot over 24" o.c. Apply Kal-Kore vertically orhorizontally in maximumlengths to minimize endjoints.

4. Furred Ceilings with BarJoists. Attach regular furringchannel 16" o.c. to barjoists spaced up to 4' o.c.Resilient Furring Channel(wire-tied only) shall span amaximum of 24". Wire tieFurring Channel to joists oruse 1 1/2" Drywall FurringChannel Clip for 1 1/2"carrying channel. ApplyKal-Kore with paper boundedges at right angles to thefurring channel.

KAL-KORE AND HI-ABUSE®

KAL-KORE APPLICATIONNote: Application shall

conform to ASTM C 844.1. Cut and position Kal-Kore

accurately. Bring all jointedges together but do notforce into place. Positionall end joints over framingmembers. To avoid ridging,minimize gaps betweenadjacent boards.

2. Minimize the number of end joints by usingmaximum practical lengthswith proper positioning.

3. Stagger joints so that theyoccur on different framingmembers and will not bedirectly opposite oneanother on partitions.

Avoid joining Kal-Kore atcorners of doors, windowframes, and other openings,unless control joints arecreated using E-Z StripControl Joints.

4. Fasten Kal-Kore to framingmembers with face out,using the proper type andspacing of fasteners shownunder types of fasteners.

5. Draw Kal-Kore tight toframing. Drive fastenersstraight and dimple thesurface without breakingthe paper face.

HI-IMPACT KAL-KOREAPPLICATIONNote: Apply in the same

manner as regular Kal-Koreand to maintain publishedimpact/penetrationresistance ratings followattachmentrecommendations below.

Screw attach 5/8" Kal-KoreFire-Shield Type X Hi-Impact vertically to 20gauge 3 5/8" steel studsspaced 16" o.c. with 1 1/4"long, type S screws spaced8" o.c. along edges and 12" o.c. in the field of theboard.

KAL-KORNER BEADAPPLICATIONInstall Kal-Korner Bead using

appropriate fastenersspaced 12" apart.

E-Z STRIP CONTROL JOINTAPPLICATIONInstall E-Z Strip Control Joint

at 30' max. spacing onwalls and 50' max. spacing

in either direction onceilings. Apply the controljoint with staples spaced 6"along each side of theflanges.

TREATMENT OF KAL-KOREJOINTSPre-treat all joints and

fasteners in Kal-Kote andUni-Kal Plaster Systemswith Kal-Kote Base Plaster,Uni-Kal, Uni-Kal 3000, X-KALibur or Sta-SmoothJoint Compound.

Low humidity, hightemperatures and rapidlycirculating air can causecracking of plaster and jointbeading when Kal-Kore isapplied to metal framing.To minimize this duringthese conditions, jointsmay be pre-treated usingpaper tape.

Three acceptable methods oftreating Kal-Kore joints are:

DRYWALL PAPER TAPETREATMENT METHOD1. Trowel Kal-Kote Base

Plaster, Uni-Kal or X-KALibur over joint linefilling the channel formedby the tapered edges of theKal-Kore board in an evenfashion.

2. Center drywall paper tapeover the joint line andembed the tape into thesoft plaster using a troweland level the joint. Tapethe full length of the joint.

3. Allow the treated joints toset prior to general plasterapplication.


09

STA-SMOOTH PAPER TAPETREATMENT METHOD1. Mix Sta-Smooth Compound

per instructions onpackage. Do notcontaminate the compoundwith other materials, dirtywater or previous mixes.Do not retemper.

2. Apply the Sta-SmoothCompound to the joint byhand or machine tool. Thedrywall paper tape must becentered over the joint lineand embedded into the softcompound. Do not over-trowel to a slick surface.Leave the surface rough toprovide mechanical keyingof the plaster.

3. Allow the treated joints toset and dry prior to generalplastering.

KAL-MESH TREATMENTMETHODDo not use self-adhering

mesh.1. Center and secure Kal-

Mesh over all joints andinterior angles with 1/4" or5/16" staples.

2. Position staples a maximumof 24" apart as follows:A. Joints: at alternate edgesfor the run from end to endand directly opposite oneanother at either end.B. Angles: along ceilingedge only for wall-to-ceiling angles. Along oneedge for wall-to-wallangles.

3. After the first staples areplaced at the end of a jointor angle, pull unstapledKal-Mesh as staplingproceeds to assure that it will lie flat against theKal-Kore.

4. Pre-treat all joints and Kal-Beads with Kal-Kote, Uni-Kal or X-KALibur Plaster.Tightly trowel over jointline in both directions toprevent voids, feathering to a maximum width ofabout 6".

5. Allow the treated joints toset prior to general plasterapplication.

PLASTERINGNote: Application shall

conform to ASTM C 843.The same general job

conditions used in goodconventional plasteringpractice should bemaintained. However,because Veneer Plastercoats are thin, particularaction must be taken to

guard against dryouts(primarily avoiding directexposure to concentratedsources of heat and drafts.)

Special attention should alsobe given to temperatureconditions under which thesystem is installed. Both“in-place” and applicationperformance of individualVeneer System componentswill be greatly enhanced ifall construction areas andmaterials are at a suitabletemperature equilibriumbefore, during and afterinstallations. During coldweather, maintain atemperature 55˚F (13˚C) to70˚F (21˚C) before, duringand after installation of allsystem components untilveneer plaster has dried.

MIXINGEquipment: Mixing should be

done with a high-speedmechanical mixer. Apaddle-type agitator fittedto a 500-600 RPM heavyduty, 1/2" electric drill anda clean, smooth-sideddrum of convenient sizeare recommended forrapid, efficient mixing of allKal-Kote Plaster types.

Water Ratios: Use only clean,fresh water suitable forhuman consumption.Basecoat: 10-12 qts. per 80lb. bag. Smooth Finish: 18-20 qts. per 50 lb. bag.Texture Finish: 11-12 qts.per 50 lb. bag. Uni-Kal andX-KALibur: 13-15 qts. per50 lb. bag.

PROCEDURE1. Put all but 1 to 2 qts. of the

proper water volume in asuitable mixing drum.

Note: Starting with aninsufficient amount ofmixing water will seriouslydegrade mixing andapplication performance.

2. Add plaster and allow tosoak for about 1 minute oradd plaster as mixer isturning, then mix untiluniformly wetted.

3. Add remaining water andmix sufficiently to obtaindesired lump-free materialfluidity.

Note:A. Mixing periods greater

than 5 minutes will not be required if properequipment and procedureare used.

B. Mix no more than two bagsper batch to avoid mixingtoo far in advance ofapplication.

C. Caution is advised againstmixing more than twosuccessive batches withoutthorough equipment clean-up to avoid undue setacceleration.

D. Avoid the practice ofmixing partial bags sincethis leads to difficulty inmaintaining uniformmaterial qualities.

JOB SETTING ADJUSTMENT1. Basecoat and Finish

Plasters: Small amounts ofcommercial retarder orcommercial gypsum typeaccelerator may becautiously used to adjustsetting time when extremeconditions demand. Whencommercial retarder oraccelerator is used, add tomixing water directly, or inpreviously prepared watersolution form to obtain themost uniform effect.

2. Never use gauging ormoulding plasters in placeof commercial acceleratorsince they can adverselyaffect working qualities.

KAL-KOTE APPLICATIONOVER KAL-KOREBasecoat Over Kal-Kore1. Tightly scratch material into

previously treated jointsand cornerbeads, thenimmediately scratch-intightly over the wall and/orceiling area.

2. Double back over the areajust troweled with materialfrom the same batchbringing total thickness upto 1/16" minimum.

3. When plaster has “takenup,” eliminate excessivetrowel marks and fill allsurface voids andimperfections to obtain areasonably uniform surface.Do not over-trowel to aslick surface. Roughen theunset basecoat plastersurface with a serrateddarby or lightly wire rake toprovide mechanical keying

for the finish plaster when necessary.

Smooth Finish Over Basecoat1. Apply only over properly

prepared Kal-Kote basecoatplaster. Scratch-in tightly,then double back withmaterial from the samebatch immediately tocreate a uniform coat notexceeding 1/16" in averagethickness.

2. Remove trowel marks, “catfaces,” and other majorsurface imperfections by“drawing-up” or “layingdown” the surface withlight trowel pressure whenplaster has stiffened.

Use water sparingly if needed,but do not over-trowel orover-water because thisaggravates any normaltendency for blisteringwhen working over lowsuction bases. Suchblistering will be eliminatedby the final water-trowelingoperations.

3. Water-trowel to densifyand polish the surface tothe desired degree whenplaster has set, eliminatingany blistering if present.Never use a felt “blisterbrush” as a substitute forwater troweling!

4. Uni-Kal and X-KALiburPlaster may be substitutedfor Kal-Kote Smooth Finish.

Texture Finish Over Basecoat1. Apply per (1) under Smooth

Finish.2. When plaster has stiffened,

float its surface to anydesired finish.

Do not float the soft surface of plaster which hasalready set.

Up to equal parts of clean,graded silica sand may be added to Uni-Kal and X-KALibur to aid texturing.


Veneer plaster performs wellin high traffic areas such as

stairways and halls.

UNI-KAL OR X-KALIBURAPPLICATION OVER KAL-KORE1. Tightly scratch material into

previously treated jointsand cornerbeads, thenimmediately scratch-intightly over the wall and/orceiling area.

2. Double back over the areajust troweled with materialfrom the same batchbringing total thickness upto 3/32" minimum.

3. Begin finish troweling attime of initial set, usingwater sparingly. Finaltroweling must beaccomplished beforecomplete set takes place, asevidenced by darkening ofthe surface.

Note: Uni-Kal or X-KALiburmay be applied to producea textured finish.A. When Uni-Kal or

X-KALibur is mixed, addup to but not exceeding50 lbs. of silica sand,texturing grade, per50 lb. bag of plaster.

B. The sanded Uni-Kal orX-KALibur mix shouldbe scratched-in tightlyover the plastering base.Immediately doubleback over the area justtroweled with materialfrom the same batch.

C. When plaster is welltaken up, float to thedesired texture finish.

VENEER PLASTERS DIRECT TO BOND-COATEDMONOLITHIC CONCRETEDESCRIPTIONThe Kal-Kote System,

consisting of a basecoatplaster and a finish coatplaster, Uni-Kal or X-KALibur may be applieddirectly to monolithicconcrete treated with abonding agent.

LIMITATIONS1. Surface to be plastered shall

be treated with a bondingagent applied according tomanufacturer’s directions.The performance of thissystem is the soleresponsibility of thebonding agentmanufacturer.

2. Concrete should be agedat least one month prior toplastering.

3. Kal-Kote Smooth orTexture Finishes are notdesigned for directapplication to concrete,but must first have Kal-Kote Base Plaster appliedto fill and level surface.

4. Do not apply system to theinterior side of exteriorwalls below grade. To useabove grade these walls

shall be kept dry and shallhave been properlywaterproofed on theexterior side to preventwater penetration.

APPLICATION PROCEDURESNote: Application shall

Veneer plaster walls are particularly suited to accommodatewall situations where light conditions require smooth, evenexpanses of wall.

The Veneer plaster wall system is particularly suited toresidential and commercial construction in areas which needstrength for special architectural details, and unusual design elements.

VENEER PLASTERS DIRECTTO UNIT MASONRY DESCRIPTIONThe Kal-Kote System,

consisting of a basecoatplaster and a finish coatplaster, Uni-Kal or X-KALibur, the one-coatsystem, may be applieddirect to masonry surfacesproviding the followingrecommendations arefollowed.

RECOMMENDATIONS1. Surface must be free from

dirt, grease, oil, mold,parting agents, or anymaterial which will preventplaster adhesion.

2. When erecting masonry,strike joints flush. Ifmasonry has recessedjoints, fill joints flush tomasonry surface withbasecoat plaster, Uni-Kal orX-KALibur and allow to set.

EXTERIOR CORNERSInstall cornerbead with

adhesive at least 4 andpreferably 16 hours beforeplastering. Apply acontinuous bead ofadhesive approximately1/4" x 1/4" along the insideof both cornerbead flanges.Press the bead firmly overthe corner so that adhesiveis in continuous contactwith masonry surface.Align bead and allow tostand undisturbed at least 4 hours.

Kal-Kote ApplicationNote: Application shall

conform to ASTM C 843.Proceed with the full field of

the wall by scratching-intightly, then double backimmediately with materialfrom the same batch to aminimum thickness of1/16" over the blocksurface, or as required tolevel.

Kal-Kote Finishes should bekept as thin as possible andapplied as described on page 44.

UNI-KAL OR X-KALIBURAPPLICATIONProceed with full field of the

wall by scratching-intightly, then double backimmediately with samebatch of material to aminimum thickness of3/32" over the blocksurface.

Caution: Since Uni-Kal or X-KALibur is a one-coatmaterial system, exercisecare in leveling the wall tocompensate for the unevensuction.

VENEER SYSTEMS APPLIEDTO MASONRY WITH ZFURRING CHANNELSYSTEMDESCRIPTIONThis system consists of a

Z Furring Channel, rigidinsulation and thecomponents of the Kal-Kote

and Uni-Kal or X-KALiburVeneer Plaster Systems.The Z Furring Channel ismanufactured fromgalvanized steel (.0179"min. base steel) and isproduced with web depthsof 1", 1 1/2" and 2". Thefurring channel which isapplied to a masonry wallholds the insulation inplace and the wide flangeserves as framing for theapplication of the Kal-Koreplastering base.

LIMITATIONS1. Since the interior wall

surface will take thegeneral configuration of themasonry wall, it may benecessary when applyingthe system to unit masonryto use portland cementplaster to bring the wall toa plane surface.

2. This system is mainly fornew masonry construction.On well-cured concrete ormasonry, it may be difficultto properly drive fasteners.

3. Power-driven fastenersshall be used only forattachment to monolithicconcrete surfaces.

4. Kal-Kore should be appliedwithin 24 hours of foamapplication.


Design flexibility is achieved with veneer plaster systems.

APPLICATION PROCEDURES1. Begin application of

Z Furring members bypositioning first channelvertically at a corner,locating it on the walladjacent to the wall beinginsulated first.

The insulation thicknessdetermines the distance ofZ Furring web from wallbeing insulated. At theappropriate distance, withwide flange pointingtoward applicator, secure Z Channel with appropriatefasteners, spaced 24" o.c.driven through short flange.(Note: Power-drivenfasteners are notrecommended for use with masonry block.)

Install 24" wide floor-to-ceiling insulation board,pressed snugly against webof first Z. Install next Z withthe wide flangeoverlapping the edge of thefirst insulation board.Fasten Z to wall throughnarrow flange. Continue inthis manner with Z Furringmember 24" o.c. to end ofwall. Locate last Z so thatweb is located a distanceequal to insulationthickness from adjoiningwall. Cut last insulationboard to fit remainingspace.

At exterior corner, attach the Zthrough its wide flange withnarrow flange extendingbeyond the corner. Beginwith a narrow strip of floor-

to-ceiling insulation, widerthan insulation thickness,but not exceeding 3".Continue application offurring and insulationprogressively as describedabove.

At windows, doors and trimareas, use wood nailers,nominal 2" wide xinsulation thickness plus1/32". Use the nailers alsoat wall-floor angles tosupport trim and providebacking for base.

2. Apply Kal-Kore to theflanges of Z Channel with1" Type S screws spaced12" o.c. Normally, verticalapplication of Kal-Kore isrecommended; however,for installations 8' or less inheight, horizontalapplication may bepreferred since the numberof joints would be reduced.

3. Apply Kal-Mesh and Kal-Korner Bead according toprocedures described onpage 48 and 49.

4. Mix and trowel on Kal-KoteBase and Finish Plaster orUni-Kal Plaster asdescribed on pages 48-51.

PAINTING PLASTERVarious job conditions such as

suction differences, wet oronly partially dry walls, andreactions between paint andlime may cause unsatisfactorypaint finishes particularlyon new construction.

Alkali-resistant primersspecifically formulated foruse over new plaster willpermit decorating with oilor latex type paints. Qualitypaint products should beused and manufacturers’recommendationsfollowed. Finished plastershould be painted orcovered to concealpossible discoloration. Thepaint system should besuitable for use over plastersurfaces that contain lime.

It is essential that plaster besound and completely drybefore painting. Undergood drying conditions,veneer plaster may bepainted 48 hours afterapplication.

High build, heavy duty andspecial purpose coatingssuch as Epoxy are notrecommended over veneeror job gauged lime puttyfinishes.

STORAGEGypsum plaster must be kept

dry before use. Storageconditions vary withlocation and seasonalchanges, which may affectstorage life. Theseconditions may affectproduct characteristics suchas setting time, workingqualities, componentseparation, or lumping, etc.Such aging is normally afunction of exposure tohumid air, temperature,and physical support inwarehousing. Adversestorage conditions orprolonged storage mayaffect the working qualitiesof the product. Rotateinventory frequently forbest results.

Our concentration isn’t onbuilding products alone,however. At the NationalGypsum Research andTesting Center, we developcomplete construction sys-tems. In such systems,products are evaluatedtogether as complete build-ing assemblies–walls, parti-tions, floors and ceilings.

We have included in this sec-tion details and applicationinstructions for many ofthose assemblies: LightSteel Frame Partitions, SteelFrame Ceilings/FurringChannels or Studs, Wood

Frame Wall and Ceilings,Wallboard Over FoamInsulated Masonry andSolid Laminated Partitions.

Before a National GypsumSystem is released to thebuilding industry, it is thor-oughly tested, and results arecorrelated and charted tomake it easier for the builderor specifier to match a sys-tem to his needs or to thebuilding codes.

The drywall construction sys-tems referred to in this cata-log are designed primarilywith materials manufac-tured by National Gypsum

Company. Substitution ofany product or otherbrands in a tested system is not recommended.

Field installation of tested sys-tems must be identical tolaboratory installation toproduce optimum perfor-mance of these systems.Performance tests are con-ducted in accordance withaccepted national stan-dards under controlled lab-oratory conditions to mini-mize variances and to per-mit comparison of testresults with all types of sys-tems, similar and dissimilar.

METRIC CAPABILITIESThe Federal Government has

mandated that each federalagency make a transition tothe use of metric units inall federal procurement,grants and business-relatedactivities. NationalGypsum Company, incomplying with this order,provides a full line of wall-board products in “hard”metric dimensions withregard to width and length.Standard board offeringsare made in the width of1200 mm and a length of3600 mm. Job size lengthsare available on a specialorder basis requiring mini-mum orders and extendedlead times. Contact yourlocal National GypsumCompany representative forfurther information.Thickness of wallboard willbe “soft” converted to themetric equivalent.

ENVIRONMENTALCONDITIONSMaintain a room temperature

of not less than 40˚F (4˚C)during application of gyp-sum board except whenadhesive is used for theattachment of gypsumboard. For the bonding ofadhesive, joint treatment,texturing, and decoration,the room temperature shallbe maintained at least at50˚F (10˚C) for 48 hoursprior to application andcontinuously thereafteruntil completely dry.

Note 1: Precaution–When atemporary heat source isused, the temperature shallnot exceed 95˚F (35˚C) inany given room or area.

Note 2: Precaution–Maintainadequate ventilation in theworking area during instal-lation and curing period.

Protect gypsum board productsfrom direct exposure to rain,snow, sunlight, or otherexcessive weather condi-tions.

GUIDELINES FORPREVENTION OF MOLDGROWTH ON GYPSUMBOARDGypsum board does not gen-

erate or support thegrowth of mold when it isproperly transported,stored, handled, installed,and maintained. However,mold spores are presenteverywhere and whenconditions are favorable,mold can grow on practi-cally any surface.Observing these guide-lines will help minimizethe potential for moldgrowth on gypsum board.Gypsum board must bekept dry to prevent thegrowth of mold.

Transportation and ReceivingGypsum board must be pro-

tected during transit with aweather-tight cover ingood condition.

Plastic shipping bags areintended to provided pro-tection during transit onlyand must be promptlyremoved upon arrival ofthe load. Failure toremove the shipping bagcan increase the likeli-hood of developing condi-tions favorable to thegrowth of mold.

Storage and HandlingGypsum board must be

stored in an area that pro-tects it from adverseweather conditions, con-densation, and other formsof moisture.

Job site conditions that canexpose gypsum board towater or moisture must beavoided.

Gypsum board must bedelivered to the job site asnear to the time it will beused as possible.

ApplicationProvisions must be made to

keep gypsum board drythroughout application.

Gypsum board that has visi-ble mold growth must notbe used.

Gypsum board on walls mustbe applied with a mini-mum 1” (25 mm) gapbetween the gypsumboard and the floor.

Gypsum board must not beapplied over buildingmaterials where condi-tions exist that are favor-able to mold growth.

Maintenance FollowingApplication

Essential elements of soundweather tight buildingenvelope must be properlymaintained, such as theroof , sealants, windows,etc.

Immediate and appropriateremediation measuresmust be taken as soon aswater leaks or condensa-tion sources are identified.

Routine cleaning and mainte-nance operations must beperformed so as to preventsaturation of the gypsumboard.

LIMITATIONS1. Maximum stud spacing for

single layer application of1/2" and 5/8" gypsum wall-board is 24" o.c. If 3/8" gyp-sum wallboard is used, itmust be applied in two lay-ers, with the second layeradhesively applied; 24" o.c.stud spacing may be used.

2. Where long, continuous runsof this wall system areemployed, control joints mustbe provided every 30' or less.

3. Where structural movementmay impose direct loads onthese systems, isolationdetails are required.

4. Partitions should not be usedwhere frequently exposed toexcessive moisture unless allsurfaces are waterproofed.

5. To prevent weakening dueto calcining, gypsum wall-board should not beexposed to temperaturesover 125˚F (52˚C) forextended periods of time.

6. Wallboard joints on singlelayer, or the face layer ontwo layer applications, shallnot occur within 12" of thecorners of door framesunless control joints areinstalled at the corners.

7. When wallboard abuts con-crete floors, cut board toallow for 1/8" to 1/4" clear-ance between board andfloor to prevent potentialwicking.

DESCRIPTION

GOLD BOND® BRAND GRIDMARX™

Gold Bond® Brand Wallboardcomes standard withGridMarX™ guide marks,printed on the paper sur-face. These guide marksalign with standard build-ing dimensions and help toquickly identify fastenerlines for stud and joistframing. Using GridMarX,accurate cuts can be madewithout having to drawlines. GridMarX also assistwith quick identification ofnail/screw pattern.

GridMarX guide marks run themachine direction of theboard at five points in 4"increments. Marks runalong the edge in bothtapers and at 16", 24" and32" in the field of theboard. The marks cover

easily with no bleed-through using standardpaint products.

Vertical Application - In a ver-tical application, GridMarXserve as a guide mark tohelp identify the exactlocation of framing mem-bers behind the gypsumboard, eliminating theneed for field applied vertical lines.

Horizontal Application - In ahorizontal application,GridMarX serve as a reference mark to helpidentify the location offraming members behindthe gypsum board. (If fram-ing member is located 2" tothe right of the GridMarXat the top edge of theboard, it will be located 2"to the right down the faceof the board.)

Fire and sound ratings forbuilding systems utilizinggypsum wallboard aredependent on the core typeand thickness of thewallboard, its application inconjunction with thecomponent parts, and themanner in which it isapplied.

Tests for fire resistance andsound transmission,performed by independentlaboratories, have resulted inspecific ratings for walls/partitions; floor/ceilingassemblies; shaftwalls,stairwells and areaseparation walls; andcolumns. For maximum fireresistance and sound control,double layer construction isgenerally recommendedsince the additional massfurther retards heat and noisepenetration.

Gypsum wallboard can beinstalled to both metal andwood framing using nails,screws or adhesives incombination with nails orscrews. In many instances,the application will dictatewhich fastening method isappropriate.

Control joints may be necessaryto prevent cracking in thegypsum wallboard facing ofdrywall systems, especiallyin areas where structuralelements such as slabs,columns or exterior wallscan bear directly on non-load-bearing partitions. Torelieve the stresses whichoccur as a result ofmovement induced bychanges in moisture,temperature or both, controljoints are required in bothpartitions and ceilings.

GYPSUM BOARDINSULATING PROPERTIESFor purposes of calculating

“U” values, the “C” factor for1" gypsum board is 1.2;Resistance “R” for 3/8" boardis .32; for 1/2" board .45; for5/8" board .56 and for 1"board .83.

RECOMMENDATIONS

Examine and inspect materialsto which gypsum board is tobe applied. Remedy alldefects prior to installation ofdrywall. Any defects in thefinished installation due tomisaligned framing or othercause will be theresponsibility of the workperformed under that sectionof the specification and suchdefects shall be remediedunder that section of thespecification.

Gypsum wallboard shall beapplied first to ceiling at rightangles to framing members,then to walls. Boards ofmaximum practical lengthshall be used so that anabsolute minimum numberof end joints occur. Boardedges shall be brought intocontact with each other butshall not be forced intoplace.

Wallboard joints at openingsshall be located so that no

end joint will align withedges of opening unlesscontrol joints will beinstalled at these points. Endjoints shall be staggered, andjoints on opposite sides of apartition shall not occur onthe same stud.

Gypsum wallboard shall beheld in firm contact with theframing member whilefasteners are being driven.Fastening shall proceed fromcenter portion of thewallboard toward the edgesand ends. Fasteners shall beset with the heads slightlybelow the surface of thewallboard in a dimpleformed by the hammer orpower screwdriver. Careshall be taken to avoidbreaking the face paper ofthe wallboard. Improperlydriven nails or screws shallbe removed.

TECHNICAL DATA

Note: To achieve tighter bending radii, use Gold Bond 1/4" HighFlex Wallboard. See page 72 for additional information and 1/4"High Flex minimum bending radii chart.

CURVED SURFACESTo apply wallboard over a curved surface, place a stop at one end of

the board and then gently and gradually push on the other end,forcing the center against the framing until the curve is complete.Shorter radii than shown in the table may be obtained by moisten-ing the face and back papers of the board with water, stacking on aflat surface, and allowing the water to soak into the core for at leastone hour. When the board is dry it will regain its original hardness.

Gypsum wallboard may be applied to curved surfaces in accordancewith the following:

RECOMMENDATIONS

Gold Bond® BRAND Fire-Shield®

Wallboard was developedto work in combination withother products in anassembly to retard heattransfer through theassembly. Fire-Shieldwallboards are made withcores formulated to offergreater fire resistance thanregular wallboard.Generically, these fireresistant wallboards that areused to delay heat transferto structural members aredesignated as “type X”products.

The gypsum core of Fire-Shieldwallboard works as anatural “sprinkler system.”Gypsum naturally contains

According to ASTM C 36, thestandard for gypsumwallboard, type X gypsumwallboard must provide atleast: a one-hour fireresistance rating for 5/8"board, or a 3/4-hour fireresistance rating for 1/2"board applied in a singlelayer nailed on each face ofload-bearing wood framingmembers when tested inaccordance with therequirements of Methods ofFire Test of BuildingConstructions andMaterials (ASTMdesignation E 119).

Examine and inspect materialsto which gypsum board isto be applied. Remedy alldefects prior to installationof drywall. Any defects inthe finished installation dueto misaligned framing orother cause will be theresponsibility of the workperformed under thatsection of the specificationand such defects shall beremedied under thatsection of the specification.

Gypsum wallboard shall beapplied first to ceiling atright angles to framingmembers, then to walls.Boards of maximumpractical length shall beused so that an absoluteminimum number of endjoints occur. Board edgesshall be brought intocontact with each other but shall not be forced into place.

Wallboard joints at openingsshall be located so that noend joint will align withedges of opening unless

about 21 percent water.When the board is heated,the water in the corebegins to evaporate and isreleased as steam,retarding heat transfer. Fire-Shield wallboardremains noncombustible.However, as shrinkageoccurs because of the lossof water volume, cracksoccur which permitpassage of fire and heat. To lessen this process, Fire-Shield wallboard isformulated by addingnoncombustible fibers to the gypsum to helpmaintain the integrity ofthe core as water volume is lost while providinggreater resistance to heattransfer.

For additional fire protection,Gold Bond Fire-Shield Cproducts are formulatedwith a mineral coreadditive which expandswhen subjected to heatwhich aids in holding thewallboard together.

Fire-Shield wallboards alsocan be used as columnprotection, delaying therapid transfer of heat toreduce the likelihood thatstructural members willlose strength and fail tocarry the intended load.

For fire safety information, go towww.nationalgypsum.com.

control joints will beinstalled at these points.End joints shall bestaggered, and joints onopposite sides of apartition shall not occur onthe same stud.

Gypsum wallboard shall beheld in firm contact withthe framing member whilefasteners are being driven.Fastening shall proceedfrom center portion of thewallboard toward theedges and ends. Fastenersshall be set with the headsslightly below the surfaceof the wallboard in adimple formed by thehammer or powerscrewdriver. Care shall betaken to avoid breaking theface paper of thewallboard. Improperlydriven nails or screws shallbe removed.

TECHNICAL DATA

1. Sta-Smooth componentsmust be used with eachother to achieve fullperformance benefits.

2. Application, except asmodified herein, shall be in accordance with ASTMC 840.

THE SECRET IS IN THE SHAPE OF THE JOINT AND THESTRENGTH OF THE COMPOUND

Standard tapered-beveled edge configuration.

Round edge configuration.

Easier Scheduling – Tapingwith Sta-Smooth Com-pounds and applying thefirst finishing coat, evenbefore the Sta-Smooth usedfor taping has dried, allowseasier job scheduling forthe drywall contractor andfinisher. This is particularlyadvantageous under slowdrying conditions.

The Sta-Smooth System produces a superior joint because theSta-Smooth Compounds are a hardening-type compound thatis not affected by humidity once it has hardened and dried. Italso maintains its hard core even with moisture added by theuse of the regular joint compounds for the finishing work. Sta-Smooth Compound firmly bonds the tape to the board and the board “V” edges to each other making a strong,rigidized joint.

Consult your local National Gypsum sales representative foredge configuration available in your market.

Sta-Smooth Brand Wallboard

Sta-Smooth is a drywall system offering maximumjoint strength and easyapplication. It can be usedin any gypsum drywall system where conventionaltypes of gypsum wallboardare recommended. This system features Sta-SmoothBrand gypsum wallboardwith a unique edge. Thetwo edge configurationsrelieve joint deformityproblems caused by twistedframing, damaged wallboard edges, pooralignment and extremes inhumidity and temperature.Regular Sta-Smooth Boardsare available in 1/2" thicknesses, 4' wide and incustomary wallboardlengths. The Sta-SmoothSystem is also composed ofSta-Smooth JointCompounds, a hardening-type taping compound andregular Gold Bond tape andfinishing compounds.

ADVANTAGESImproved Durability – The

Sta-Smooth System produces a smooth, flat,durable surface that relievesbeading, ridging and otherjoint deformity problems.

Greater Speed – All flat joints in the Sta-SmoothSystem are filled and tapedwith any Sta-SmoothCompounds all in one easyoperation, the same as conventional wallboardapplication methods. Sta-Smooth Compounds or regular compounds can beused to tape inside corners,cornerbeads, and spot fasteners. Regular ProFormfinishing compounds orSta-Smooth compounds areused for the remainingfinishing coats.

Easier Handling – Theimproved edge designs onSta-Smooth Boards makeshandling easier with greatercomfort to the hands.

No Special Equipment – Allconventional fasteners,adhesives, and gypsumwallboard application tools(T-squares, knives, etc.) canbe used to apply Sta-Smooth Boards. Nothingnew to buy.

Alignment – Sta-Smoothboard with its unique edge(either configuration)allows for easy alignmentof the boards in the sameway as conventionaltapered edge wallboard.The taper is scientificallydesigned to reducecrowned joints.

Stronger Bond – The bondingarea of the Sta-SmoothJoint Compounds areincreased with the “V”edge boards. The Sta-Smooth Joint Compoundused to bond the joint tapeand fill the joints is a hardening-type, high density material with low shrinkage characteristics.

Strength – The Sta-Smoothjoint shape and the jointcompound are developedto provide greater massand integral bond forincreased strength. Sta-Smooth Joint Compoundsadd considerable strengthwhich is unaffected by the amount of moisturenormally introduced into astructure that could causeridging or beading withconventional joint compounds.

Cost – If application techniques are followed asrecommended, the Sta-Smooth System should costno more and can cost considerably less than conventional gypsum drywall joint finishing. The initial savings areimmediately demonstratedwith reduced travel timethat results from this perfected 2-trip, 3-stepjoint finishing system.Future cost savings will berealized with reduced callbacks.

Better Butt Joints –Recommended with the Sta-Smooth System is animproved technique forproviding a smoother, flatter, stronger butt joint.Although this techniquecould be used in conventional drywall work and produce betterbutt joints, it is furtherimproved by the use of thehigh strength Sta-SmoothCompound.

Thickness: 5/8".2. Width: 4'.3. Length: 8' through 12'.4. Edge: Beveled Tapered (Sta-Smooth Edge).



Note: Sta-Smooth Gypsum Wallboard may be used with any ofthe Gypsum Drywall Systems described in this GypsumConstruction Guide.

All specifications for the application of gypsum wallboardboards as described in this literature may also serve for theapplication of Sta-Smooth Boards. Any deviation from thesespecifications is as indicated below.

A. BOARD APPLICATION: Position each Sta-Smooth Board sothat the long edges are in light contact with the edges of theprevious boards. All boards positioned to form butt jointsshould have a gap approximately 1/16" between the boardends. This spacing can be assured by driving 2 extra fastenersat the end of the board to act as temporary spacers beforeabutting the next board. When the boards are fastened inplace, drive the temporary spacers flush with surface. Whenwallboard is applied horizontally, recess all butt joints on thejob by shimming the face of the studs (or joists), on both sidesof the studs (or joists), on which the joint will fall. The shimcan be pressed paper, thickness of building felt or other suitable materials not to exceed 1/16" thickness and as wide asthe stud or joist. It should be 6" longer than the butt joint andapplied to the face of the stud or joist with staples or nailsallowing the shim to extend under the edge of the abuttingboards of wallboard to assure that the board facings remain onthe same plane.

B. CORNERS AND OPENINGS: All exterior corners, and allopenings that require joint treatment should receive protective reinforcement of Gold Bond Multi-Flex Tape Beador Steel Cornerbead or Steel Casing Bead as required.

C. TREATMENT OF JOINTS*: All flat Sta-Smooth wallboardjoints are taped with Sta-Smooth Compounds, making surethat a sufficient amount of compound is forced into the “V”joint and spread under the tape to form a solid foundation forthe finishing coats.**

1. As soon as the Sta-Smooth Joint Compound used for taping hashardened, the first finishing coat can be applied even whenthe Sta-Smooth Compound is still wet.

2. When the first finishing coat is completely dry the second finishing coat can be applied. Any of the ProForm JointCompounds may be used for the finishing coats.

3. Sta-Smooth Joint Compounds are recommended for the firstcoat on nail or screw heads. Regular finishing compoundsmay be used for subsequent spotting of the fasteners. Sta-Smooth Compounds are also recommended for the first coaton cornerbead and followed by one or more finishing coatsas required of regular ProForm Joint or Topping Compounds.

4. The inside corners may be treated with any of the ProFormJoint Treatment Compounds recommended for taping. If atwo-trip joint treatment operation is planned, the inside corners are taped with Sta-Smooth Joint Compounds. Thiswill permit finishing one side of the inside corners the firstday. Cornerbead is treated with Sta-Smooth Compounds if atwo-trip operation is employed.

*Alternate Method: When mechanical tools are to be used for taping joints, Sta-Smooth Compounds are used to fill the “V”joint only. Other ProForm Joint Compounds are then used tobed the tape and finish the joints. (See page 66.)

**Sta-Smooth, Sta-Smooth HS and Sta-Smooth Lite JointCompounds are recommended for prefill or tape/bed coatoperations in the Sta-Smooth system.

See page 60, Environmental Conditions and Limitations.


3. Second Finishing Coat

TAPING AND FINISHING WITH MECHANICAL TOOLSTaping – Taping tools such as the “banjo” and “hopper” types are recommended for

taping the flat joints with Sta-Smooth Compounds and the inside corners with ProFormregular joint compounds or with Sta-Smooth Compounds. Automatic taping tools arenot recommended for use with hardening-type compounds. Mechanical tools can beused for taping the inside corners when a ProForm regular joint compound is used. When automatic taping tools are used for taping the flat joints, the“V” formed by the edges of Sta-Smooth board on the flat joints and all spaces betweenthe wallboard edges on butt joints are prefilled with Sta-Smooth Compounds andallowed to harden (30 minutes longer than the set time designated on the bag) prior totaping with a regular ProForm joint compound.

Finishing – Mechanical type finishing tools can be used in the normal manner for thefinishing operations of the Sta-Smooth System since conventional ProForm finishingcompounds are used.

MIXING INSTRUCTIONSSta-Smooth Compounds are available in 20, 45, 90 and 210 minute set times. MIX NO

MORE COMPOUND THAN CAN BE APPLIED IN THE DESIGNATED SET TIME.Contact your National Gypsum Company Representative for availability. A plasticcontainer is recommended because of its ease in cleaning between batches. Do notuse a wood or aluminum bucket. Add the compound gradually to clean water whilestirring. Note: Use only fresh, clean water suitable for human consumption. Mix at theratio of 13-14 pints of water to the 25 lb. bag. Mix the compound free of lumps with amechanical mixer or by hand. Mechanical mixing is recommended. Allow to stand 5minutes as a “wetting” period and remix to further improve the working qualities. If a slightly thinner compound is desired, add an additional pint of water, orless, after the compound is thoroughly mixed.

INSTALLATION

APPLICATION AND FASTENINGSta-Smooth Boards may be nailed, screwed or adhesively applied to wood studs or

furring, or screwed or adhesively applied to steel studs or furring, using conventionaltype and length of fastener. All fasteners shall be applied a minimum of 3/8" (maximum 1/2") from the edges and ends of each board. Then treat the joints in three simple steps.

CONVENTIONAL TAPING AND FINISHING1. Fill Joint And Bed Tape SimultaneouslyAll flat wallboard joints are to be filled and taped in one operation with Sta-Smooth

Compounds, using ProForm Paper Tape in the conventional manner. When Sta-Smooth HS tape is used, the self-adhering fiberglass mesh tape is firmly pressed to thewallboard, spanning the joints. Sta-Smooth Compounds can then immediately beapplied to the joints. The compound must be forced through the tape to fill the channel formed by the “V” edges of the Sta-Smooth wallboard. All inside corners maybe taped using regular ProForm compounds. Sta-Smooth Compounds are used for thefirst coat on nail or screw heads and will decrease problems with fastenerimperfections. Inside angles, first and second finishing coats may be done using regular Gold Bond joint compounds.

2. First Finishing CoatAs soon as the Sta-Smooth Compound used for taping has hardened, the first finishing

coat may be applied on the flat joints even before it is dry. Any ProFrom joint compound may be used for this operation. A second coat may be applied at this timeto nail or screw heads, one coat on cornerbead if Sta-Smooth Compound was used forthe first coat.

3. Second Finishing CoatAs soon as the compounds used for the previous steps have thoroughly dried, a second

finishing coat is applied to all flat joints using ProForm Joint Compound or ToppingCompound. A third coat is applied over nail or screw heads and on cornerbead asrequired. The unfinished side of the inside corners is also finished at this time.

STA-SMOOTH ROUND EDGE REQUIRES PRE-FILLING PRIOR TO BED & TAPINGApplication Instructions For Round Edge Sta-Smooth Wallboard1) Mix Sta-Smooth Joint Compound, Sta-Smooth Lite Joint Compound or Sta-Smooth HS

Joint Compound as per bag instructions. Care should be taken to mix no more compound than can be applied in the designated set time.

2) Pre-fill all joints formed by the abutting round edge Sta-Smooth wallboards with Sta-Smooth Compound, Sta-Smooth Lite Joint Compound or Sta-Smooth HS JointCompounds using a conventional joint finishing knife. Fill joints, level and wipe offexcess compound to the lowest level of the taper, allowing enough room for embedding the tape. Allow prefill material to harden prior to application of tape andbed coat.

3) Finish joints in the normal manner.

Hi-Impact® Brand WallboardDESCRIPTION TECHNICAL DATA

IMPACT/PENETRATION RESISTANCE RATINGPER ASTM D 2394 MODIFIED*

IMPACT/PENETRATION RESISTANCE RATING

This is one tough wallboard. By combining the surface tough-ness of Hi-Abuse Brand Wallboard with the strength ofLexan®,* National Gypsum has created a wallboard that canreally stand up to scrapes and hard knocks. The newly improved Hi-Impact Brand Fire-Shield Wallboard provides the maximum combination of abrasion resistance andimpact/penetration resistance for those areas faced withexceptionally high levels of wear and tear. Here’s a wallboardthat can go in places you never dreamed gypsum wallboardcould go before.

Hi-Impact Brand Wallboard

As strong and tough as it is, Hi-Impact Brand Wallboard is aseasy to use and install as regular gypsum wallboard. Lessexpensive and labor intensive than concrete block and fiber-reinforced gypsum boards, the original Hi-Impact BrandWallboard has quickly become the preferred choice of archi-tects and contractors. Now, that original is even better andtougher with the addition of improved surface abrasion resis-tance. Thus, improved Hi-Impact Brand Fire-Shield Wallboard is superbly suited for all those really tough jobs, such as schools, correctional facilities, dormitories, hospitals, mass transit facilities, public housing, common areas and retail separation walls.

Hi-Impact Brand Wallboard boards are backed with Lexan®

substrate and are available in four increasingly higher levelsof impact resistance:

1. Hi-Impact Brand 1000 with a 0.010" Lexan® substrate




And, just like regular wallboard, Hi-Impact Brand Wallboard canbe cut and installed quickly; so painting, other decoration andthe installation of most metal and wood trim can begin almostimmediately.

With Hi-Impact Brand Wallboard, now tough walls can still begood looking.

Each 5/8" board consists of a fire resistive type X gypsum coreencased in heavy, smooth, white abrasion-resistant paper onthe face side and strong liner paper on the back side. Lexan®

substrate is bonded to the back side of the board to provideadditional impact/penetration resistance. Long edges of theboards are tapered to allow joints to be reinforced and con-cealed with ProForm Joint Tape and ProForm Joint TreatmentCompounds.

Gridstone Brand Ceiling Panels


Gridstone Brand prefinished ceiling panels have a non-combustible, Fire-Shield G gypsum core. The 2-mil. white, stipple-textured vinyl laminate combines high light reflectance with easy cleanability.

Gridstone panels can be used for interior and exterior ceiling applications.

Gridstone Ceiling Panels install easily in standard 2' by 2' and 2' by 4' exposed grid systems. Ceiling panelshave a rigid gypsum core which provides extra resistance to sagging and warping.

A noncombustible gypsum core assures fire safety with1 1/2- and 2-hour fire rating achievable depending on installation.

The sturdy white vinyl laminate eliminates additional finishing.

As little as 1" of material can be cut from Gridstone panels with practically none of the crumbling common with mineral fiberpanels.

For exterior application, protect grid panels from direct exposure to weather, water and continuous high humidity. Under no circumstances should water be in contact with the back of the panels.

Overlaid insulation may causeexcessive panel deflection and is not recommended where high humidity is likely to occur.

Extreme lighting conditions may distort texture appearance.

The use of strong organic solvents (such as ketones), harsh abrasive cleansers or steel wool are not recommended. These materials may cause dulling, discoloration, softening and other permanent damage to the vinyl surface.

USDA Acceptance: Gridstone panels are accepted by the USDA for use in food service and food processing areas.

RECOMMENDATIONS

Gridstone ceiling panels are designed to be mounted in standard 15/16" exposed tee grid systems or environmental type grids for severe conditions, with grids either 2' by 2' or 2' by4'. Grid installation should be conducted according to manufacturer's specification.

Each panel must be supported on all four (4) edges.

Cross ventilation must be provided in unheated or enclosed space above ceiling panels.

General: Install panels in lay-in suspension systems with edges concealed by flanges of suspension members. Cut boards to fit tightly at borders and penetrations sothat cut edges are concealed by trim pieces and escutcheons.

Cleaning: Common dirt and stains on the vinyl surface can be removed with mild soap or detergent in lukewarm water. Use a light, scrubbing action with a cloth, sponge or soft brush.

If the suitability of any cleaning agent is unknown, check its effect on the Gridstone panel surface in a hidden area or on a scrap piece before attempting to remove a field stain.

Gridstone Ceiling Panels are not recommended for use in areas exposed to extreme or continuous moisture such as found in saunas, steam rooms, gang shower rooms or swimming pool enclosures.

DECORATIONGridstone Brand Ceiling

Gold Bond Brand Foil Back Wallboard

DESCRIPTION LIMITATIONS1. Not recommended for

use where exposure to moisture and high outside temperature is extreme and continuous. Under these conditions, a qualified mechancial engineer should determine location of the vapor retarder.

2. Not to be used as a base for ceramic or other tile or as a base layer for prefinished vinyl wall boards in double-layer assemblies. Also, not to be used as a base for adhesively applied vinyl or other highly water-vapor-resistant wall coverings.

3. To prevent objectionable sag in ceilings, weight of overlaid unsupported insulation should not exceed:1.3 lb./sq. ft. for 1/2" thick boards with frame spacing 24" o.c.; 2.2 lb./sq. ft. for boards with frame spacing 16" o.c. Boards 3/8" thick must not be overlaid with unsupported insulation. Unheated attic spaces shouldbe properly ventilated.

4. Foil Back Gypsum Wallboardis not recommended for use in hot, humid, climates such as the Southern Atlantic and Gulf Coast areas.

MATERIALSManufactured boards with

gypsum core, paper-encased with aluminum foil laminated backing.

SIZES AND TYPESThickness Width Length

1/2" 4' 6' to 16'3/8" 4' 6' to 16'5/8" 4' 6' to 16'

Edges: Square, tapered or Sta-Smooth.

APPLICABLE STANDARDSASTM C 36/C 1396

Gold Bond Foil Back Wallboard boards consist of a fire-resistive gypsum core encased in heavy natural-finish paper on the face side and strong liner paper on the backside to which aluminum foil is laminated. The ends are square cut and finished smooth.

BASIC USESFoil Back Wallboard can be used

for exterior walls and ceilings in new construction and remodeling. The aluminum foil, laminated to the back surface, is a vapor retarder to keep interior moisture within the building at a suitable comfort level. For use with furred masonry, wood or steelframing, Gold Bond Foil BackWallboard is effective for single-layer applications and as a base layer in double-layer applications where a vapor retarder of 0.1 perm or less is required.

ADVANTAGES1. In tests conducted according

to ASTM Test Procedure E 96 (desiccant method), 1/2" Foil Back Wallboard showed a performance of 0.06 perm compared to 34.2 perm for1/2" regular gypsum wallboard and 28.4 perm for 1/2" gypsum wallboard with two coats of flat latex paint.

2. In-place cost of Foil Back Wallboard installation is lower per thousand sq. ft. than a similar installation for regular gypsum wallboard and polyethylene-film retarderinstalled separately.

3. Easy-to-handle Foil Back Wallboard is adaptable to virtually all exterior wall and ceiling construction: wood frame, furred masonry.

Boards of maximum practical length should be used so that an absolute minimum number of end joints occur. Board edges should be brought into contact with each other but should not be forced into place.

Wallboard joints at openings should be located so that no end joint will align with edges of openings unless control joints will be installed at these points. End joints should be staggered, and joints on opposite sides of a partition should not occur on the same stud.

Gypsum wallboard should be held in firm contact with the framing member while fasteners are being driven. Fastening should proceed from center portion of the wallboard toward the edges and ends. Fasteners should be set with the heads slightly below the surface of the wallboard in a dimple formed by the hammer or power screwdriver. Care should be taken to avoid breaking the face paper of the wallboard. Improperly driven nails or screws shall be removed.

For best painting results, all interior surfaces, including joint compound, should be clean, dust-free and not glossy. To improve fastener and joint concealment, a prime coat of drywall primer is recommended to equalize the porosities between surface paper and joint compound.


TECHNICAL DATA

SURFACE BURNINGCHARACTERISTICS(ASTM E 84)Flame spread: 15Smoke developed: 0FIRE RESISTANCE RATINGSFoil Back Wallboard has not

been used in fire resistance tests. Fire resistance ratings represent the results of tests on assemblies made up of specific materials in a specific configuration. When selecting construction designs tomeet certain fire resistance requirements, caution must be used to ensure that each component of the assembly is the one specified in the test. Further, precaution should be taken that assembly procedures are in accordance with that of the tested assembly. (For copies of specific tests, call 1-800-NATIONAL or 1-800-628-4662.)

RECOMMENDATIONS

Examine and inspect materialsto which gypsum board is to be applied. Remedy all defects prior to installation of Gypsum Board. Any defects in the finished installation due to misaligned framing or other cause will be the responsibility of the work performed under that section of the specification and such defects shall be remedied under that secton of the specification

Gypsum wallboard should be applied first to ceiling at right angles to framing members, then to walls.

wallboard and the steelstuds acting as a compositesection to provide amaximum deflection ofL/120, L/240, L/360 (L = partition height ininches) with a horizontalload of 5 psf, 7.5 psf, and10 psf of partition surface.

Increased rigidity may beobtained by placingstiffener channels throughthe steel stud cut-outs, byusing two layer applicationof gypsum wallboard or bydecreasing stud spacing.

Standard 25 and 20 gaugestuds, recommended forinterior partitions, haveheight limits as shown inTables 1 and 2. Wallboardmust be attached to fullheight on both sides ofstuds with Type S BugleHead Drywall Screws(Type S-12 for 20 gaugestuds) spaced not morethan 12" o.c. on all studswhen framing is 24" o.c.and 16" o.c. if framing is16" o.c. or less. Screwlengths must be not lessthan 3/8" greater than thetotal thickness of thewallboard being fastened.

Light steel 20 gauge studs aredesigned for exterior,nonload-bearing curtainwall systems, but are alsoused for interior partitionsto provide more ridigity orgreater heights than can beobtained with Standard 25gauge studs.

LIMITATIONS1. Maximum stud spacing for

single layer application of1/2" and 5/8" gypsumwallboard is 24" o.c. If 3/8"gypsum wallboard is used,it must be applied in twolayers, with the secondlayer adhesively applied;24" o.c. stud spacing maybe used.

2. Where long, continuousruns of this wall system areemployed, control jointsmust be provided every 30'or less.

3. Where structural movementmay impose direct loads onthese systems, isolationdetails are required.

4. Partitions should not beused where frequentlyexposed to excessivemoisture unless all surfacesare waterproofed.

5. To prevent weakeningdue to calcining, gypsumwallboard should not beexposed to temperaturesover 125˚F for extendedperiods of time.

6. Wallboard joints onsingle layer, or the facelayer on two layerapplications, shall notoccur within 12" of thecorners of door framesunless control joints areinstalled at the corners.

7. For limitations regardingselection of doors anddoorframes, refer to tableon page 88.

8. Where reference is madeto nominal gauges, 25gauge relates to aminimum base steel of.0179", and 20 gauge to.0329".

RECOMMENDATIONS

1. FRAMINGAlign floor and ceiling tracks to assure plumb partition.

Secure track with suitable fasteners at a maximum of 24"o.c. Position studs in track on 16" or 24" centers byrotating into place for a friction fit. Steel studs shall beinstalled with all flanges pointed in the same direction.Secure studs located adjacent to door and window frames,partition intersections and corners with 3/8" Pan HeadType S Screws driven through both flanges of studs andtracks or by using a stud clincher.

2. SINGLE LAYER OR FIRST PLYApply gypsum wallboard with the length parallel or at right

angles to the studs. Center abutting ends or edges over thestud flanges.

For metal framing, screws shall be Type S, of a length toprovide not less than 3/8" penetration into framing andshall be spaced 24" o.c. max. If no adhesive is used,standard fastener spacings shall prevail.

For non-fire-rated construction, locate all attaching screws12" o.c. when framing is 24" o.c. and 16" o.c. whenframing is 16" o.c. or less. For fire-rated construction,vertical application, space screws 12" o.c. in the field and8" o.c. along the vertical abutting edges unless otherwisespecified. Attach the gypsum wallboard to Steel Studs withType S Drywall Screws using an electric, drywallscrewdriver with a #2 Phillips bit. For vertical wallboardapplication with studs 24" o.c., erect the wallboard on oneside of the partition, screw attaching to open end of studflange first at vertical wallboard joints. Complete thewallboard application to the entire side of the partition inthis manner. For the opposite side, cut the first wallboardboard 2' wide so that joints will be staggered. Fasten thisand succeeding wallboard boards to all studs on this side.When partition face is complete, return to the first side andcomplete screw attachment of wallboard to allintermediate studs.

Make door and window framing openings of such size thatwhen the wallboard is secured to the studs, it will fitsnugly into the steel frames.

3. FACE LAYERMechanical attachment of face layer for fire or sound rated

constructions shall be made in acordance with thespecifications for the system selected. When the face ply isattached with mechanical fasteners and with no adhesivebetween plies, the maximum spacing and minimumpenetration recommended for screws should be the sameas for single ply application.

4. DOOR FRAMESAlthough one-piece metal door frames may be used with this

system, the three-piece metal door frame is preferred bymost contractors. This type of frame permits installationafter the walls are erected, which normally results in fastercompletion of the job.

Wood Frame Walls and Ceilings/Single Layer Construction

DESCRIPTION

STANDARD APPLICATIONStandard application (single

nailing) Regular Gold BondGypsum Wallboard isusually applied directly towood framing members.Ceilings are applied first,then sidewalls. Boardsshould be accurately cutand joints abutted but notforced together. Horizontalapplication, long edges atright angles to nailingmembers, is preferred for itminimizes joints andstrengthens the wall orceiling. Nails shall bespaced not to exceed 7" onceilings, or 8" on sidewalls,a minimum of 3/8" and amaximum of 1/2" fromedges and ends ofwallboard. Gypsumwallboard nails or annularring nails, such as theGWB-54 illustrated above,are recommended. For adescription of the varioustypes of Gold BondGypsum Wallboards, referto pages 56 through 85.

DOUBLE NAILINGDouble nailing is an alternate

method of attachmentdevised to minimize nail-pops. This system requiresdoubling up on the fieldnails. The total quantity ofnails used does not double,however, since maximumnail spacing is increased to12" o.c. and conventionalnailing is used on theperimeter. Application isaccomplished by first singlenailing the field of theboard, starting at the centerand working toward endsand edges. Another nail isthen driven in closeproximity (2" to 2 1/2") toeach of the first nails. Thefirst series of nails are thenstruck again to ensure theboard is drawn tightly tothe nailing member.

FLOATING ANGLEMETHODFloating angle method of

gypsum wallboardapplication eliminates theuse of the perimeter nails atinterior corners and whereceilings and walls meet.This method reduces thestress and strain on theboard if framing settles.Reference ASTM C 840,Section 9.

ADHESIVE NAIL-ONMETHODApply drywall adhesive to

face of studs or joists incontinuous beads.Reference ASTM C 840Section 10.

FIRE RESISTANCE RATINGSWhere fire ratings are

required, refer to pages 10, 11, 19, and 20. Forcomplete constructiondetails consult the specifictest report.

SCREW APPLICATIONScrew application is often

preferred as the screwholds the gypsumwallboard tight against theframing when applied asrecommended. Type W 1 1/4" Drywall Screws aredriven with an electricscrew gun equipped withadjustable screw depthcontrol and a #2 Phillipsbit. If framing is spaced upto 16" o.c., screws arespaced 12" o.c. max onceilings and 16" o.c. maxon walls. If framing isspaced 24" o.c., screwspacing must not exceed 12" o.c. Minimum screwpenetration shall be 5/8" forwood studs.

RECOMMENDATIONS1/2" or 5/8" gypsum wallboard

single layer application isrecommended for interiorfinishing of all buildingswith wood frameconstruction. The use of5/8" gypsum board or 1/2"High Strength Ceiling

Board on ceilings willminimize sagging. Duringcold weather the use ofpolyethylene film as aceiling vapor retarder is not recommended unlessceiling insulation isinstalled prior toapplication of wallboard.

LIMITATIONS1. 1/4" Gold Bond Gypsum

Wallboard should beapplied only to existingsurfaces and should not beapplied directly to framingmembers, except whenused with other thicknessesin double layer systemstested for specific purposes.Existing walls and ceilingsshould be sound, flat, leveland without void spaces.1/4" thick gypsum boardshould be applied with acombination of mechanicalfasteners, nails or screws,and adhesive that will bondto the substrate surfacecovering. Nails or screwsshould penetrate framingspaced not over 24" o.c.Adhesive should be appliedbetween framing membersto bond the wallboard tothe substrate.

2. 3/8" Gold Bond GypsumWallboard should not beused on nailing membersover 16" o.c. When appliedto ceilings, the wallboardmust be applied with thepaper bound edges at rightangles to the nailing mem-bers and shall not be usedto support insulation. 1/2"or 5/8" Gypsum Wallboardshould not be used onnailing members over 24"o.c. When applied toceilings with the nailingmembers exceeding 16"o.c., the wallboard must beapplied with the paperbound edges at right anglesto the nailing members.

3. If gypsum wallboard ceilingboards are nailed to crossfurring, these membersshall have a minimumcross section of 2" x 2"(nominal) with samespacing limitations asabove. With screws,nominal 1" x 2" furring maybe used. Spacing of the

framing members toreceive furring must notexceed 24" o.c.

4. In single ply installation, allends and edges of gypsumboard should occur overframing members or othersolid backing except wheretreated joints occur at rightangles to framing or furringmembers.

5. Hold the gypsum wallboardfirmly against the framingwhile fastening with nailsor screws. Start at thecenter and work towardeach end and edge,spacing the fasteners asrecommended for eachtype of application.

6. Lighting and other fixturesshall be supported byframing; do not use gypsumwallboard to support them.

7. Gypsum wallboard ceilingsto be decorated with water-thinned spray texture shallbe 1/2" or 5/8" thick andapplied perpendicular tothe framing. Framing shallnot exceed 16" o.c. for 1/2" regular wallboard and 24"o.c. for 1/2" High StrengthCeiling Board and 5/8" wallboard.

8. Gypsum wallboard ceilingsto receive a spray texturefinish must be primed witha sealing latex primer andallowed to dry beforespraying. This is tominimize sagging of thewallboard anddiscoloration problems.

The use of water-based spraytextures may cause un-primed gypsum wallboard to sag when any one ormore of the followingconditions exist:

1. Unventilated buildings.2. Use of vapor retarders

under certain conditions.3. Periods of prolonged high

humidity due to eitherweather conditions orclosed building units (poordrying conditions).

4. Inadequate framing support(can occur where framingchanges direction).

5. Improper type or thicknessof gypsum board.


INSTALLATION

RECOMMENDATIONS

FLOATING ANGLESNo nails in shaded area.

SCREW APPLICATIONFast, positive, fewer heads to treat.

ADHESIVE / NAIL-ONIdeal for prefinished boards.

DOUBLE NAILINGMinimizes nail-pop.

SINGLE LAYER WALLBOARDAPPLICATION (also BaseLayer of Double Layer)1. NAILSNails shall be GWB-54 or

cooler type located 3/8"min. to 1/2" max. fromedges and ends ofwallboard. Nails shall be amax. of 7" o.c. on ceilingsand a max. of 8" o.c. onwalls, except for “DoubleNailing” Procedure.

2. SCREWSDrywall screws for attaching

gypsum wallboard to woodframing shall be 1 1/4",

Type W spaced not toexceed 12" o.c. on ceilings,16" o.c. on sidewalls wherestuds are 16" o.c. and 12"o.c. on sidewalls wherestuds are spaced 24" o.c.Screws for attachinggypsum wallboard togypsum wallboard shall beType G spaced as required.

3. STAPLESBase layer gypsum board may

be applied with power-driven staples spaced 7"o.c. on ceilings; 8" o.c. onsidewalls. Staples shall beU.S. Standard 16 gaugegalvanized wire staples

with 7/16" wide crownwith legs having divergentpoints. Legs shall be notless than 1" long for 3/8"base board, 1 1/8" long for1/2" base board or 1 1/4"long for 5/8" base board.

4. CORNERBEADSCornerbead shall be nailed

with gypsum wallboardnails spaced no greaterthan 9" apart on eachflange of the bead with thenails opposite. In lieu ofnailing, cornerbead may becrimp applied 6" o.c. with aspecial tool.

5. ADHESIVE APPLICATIONTO FRAMING

A. Apply wallboard adhesiveto the wood framing with acaulking gun.

B. For application of pre-decorated gypsum board,refer to Durasan PrefinishedWall Boards section, page141.

FLOATING INTERIORANGLES To minimize fastener popping

in areas adjacent to walland ceiling intersections,the floating angle methodshould be used for eithersingle or double layerapplication of gypsumboard to wood framing.This method is applicablewhere single nailing,double nailing or screwattachment is used.Gypsum board should beapplied to ceiling first.

REPAIRING NAIL-POPS Nail-pops are caused by

lumber shrinkage afterboard application; loosegypsum board; improperlyaligned, twisted or bowedframing; or impropernailing.

Pops appearing before/duringdecoration should berepaired immediately.Those which occur afterone or more month’sheating are usually causedby lumber shrinkage andshould not be repaired untilafter heating season. Torepair, renail about 1 1/2"from the popped nail alongthe framing while applyingsufficient pressure adjacentto the nail to bring board infirm contact with theframing. If the popped nail

was improperly driven,remove it. If properlydriven, reseat just belowthe board face. Removeany loose material overreseated nail before treatingnail heads with jointcompound andredecorating.

ADHESIVE NAIL-ONAPPLICATIONThe adhesive nail-on system

for application of gypsumwallboard to wood framingmembers strengthens thewall and minimizes thepossibility of nail-popping.It reduces the number ofnails in the field, providesfor intimate contact and acontinuous bond betweenthe wallboard and woodframing. All surfaces thatcome in contact with theadhesive should be dry,free of dirt, grease, oil orother foreign materials.

SCREW APPLICATIONDrywall screws attach gypsum

board to wood or steelframing or to other gypsumboards. They pull the boardtightly to the supports,minimizing surface defectsdue to loose boards. Whenproperly driven, they makea uniform depression freeof ragged edges and fuzz.

2. Laminating is an excellentway to apply Durasan, thevinyl-surfaced gypsumwallboard boards. Thismethod eliminates any visible attachment.

3. Sta-Smooth Compound or Sta-Smooth Lite is recommended for laminating as well as forjoint treatment where fasthardening is required.

LIMITATIONS 1. Joints of succeeding layers

must not fall at the samelocation. For greateststrength, it is recom-mended that the boards ofeach layer be staggered sothat joints of each layer areat least 10" apart.

2. During cold weather, maintain a room temperature of not lessthan 40˚F during mechanical attachment ofgypsum wallboard, andbetween 50˚ and 70˚F for 48 hours before lamination, joint treatment,texturing and decoration,and continuously thereafteruntil completely dry.

A. Z FURRING CHANNEL 1. Application of Foam.

Z Furring Channel is usedto secure rigid insulationand gypsum wallboardboards to masonry walls.Insulation thickness (1", 1 1/2", 2") determines depthof Z furring web. Thechannel is appliedvertically and fastened tothe masonry wall throughthe short (3/4") flange withsuitable masonry fasteners24" o.c. maximum.Application is progressive.After fastening each ZFurring Channel, a 24"wide floor-to-ceiling-highinsulation board is fitbetween the wall and thewide (1 1/4") flange.

2. Application of Wallboard.Erect Gold Bond GypsumWallboard either verticallyor horizontally to the Z Furring Channels.Wallboard edges or endsthat run parallel to thechannels shall be centeredand abutted over channels.Fasten wallboard with 1"Type S Drywall Screwsspaced 12" o.c. Whenwallboard erection iscomplete, finish all jointsand screw heads inaccordance with ProFormJoint Finishing System.Prefinished gypsumwallboard boards may belaminated vertically to thechannels with screws at topand bottom.

Limitations Power driven fasteners should

be used to secure furringonly when wall ismonolithic concrete.Regular concrete nails canbe used for fastening to unitmasonry. If block is old,test nailing should be donein advance to determineoptimum size and type of nail.

B. LAMINATION 1. Application of Foam.

Insulation may be urethanefoam or extrudedpolystyrene. Expandedbead polystyrene is not

recommended. Forhorizontal wallboardapplication, install woodfurring strips (nominal 2"wide x 1/32" greater thanthe foam thickness)horizontally along the wall-ceiling and wall-floorangles, where horizontalwallboard joints will fall,and around door andwindow openings. Forvertical wallboardapplication, furring stripsare required at thehorizontal wall-ceiling andwall-floor lines and arounddoor and windowopenings.

Masonry surface must be dry,clean and free of dust, dirt,form release agents, oil,grease or water solublematerials. Treat paintedmasonry as recommendedfor laminating to paintedsurfaces. Apply adhesive tothe foam insulation in 3/8"dia. beads continuouslyaround the perimeter andthrough the field in the longdirection with the beadsspaced 16" o.c. Contactadhesive manufacturer forcompatability with foam.

Apply the foam boardshorizontally to the wallwith a sliding motion andhand press entire board toinsure full contact ofadhesive and wall surface.

2. Application of Wallboard.ProForm All-Purpose JointCompounds may be used.(Do not use water basecompounds for laminatingprefinished boards tofoam.)

Permanent nails or screws 12" o.c. are required tofasten wallboard to woodfurring. Wallboard must beinstalled a minimum of 1/8" from the floor. Usetemporary nails or bracingas necessary to holdwallboard boards in firmcontact to the foam untiladhesive has dried or set.

Limitations 1. Nails or screws used for

attachment of wallboard

boards to furring strips mustnot penetrate through thefurring.

2. Power driven fastenersshould be used to securefurring to monolithicconcrete. Regular concretenails can be used forfastening to unit masonry. Ifblock is old, test nailingshould be done in advanceto determine optimum sizeand type of nail.

3. During cold weather, roomtemperature between 50˚Fand 70˚F must bemaintained uniformlyduring application anduntil adhesive is thoroughlydry or premises areoccupied. Provideadequate ventilation.

4. Gypsum wallboard is notrecommended in areas

where it will be exposed toexcessive moisture orcontinued high humidity.

5. Since the use of foamplastic insulation isregulated by many buildingcodes, consultation withlocal building authorities isrecommended beforeinstallation.

Since unprotected foaminsulation may represent afire hazard, it should becovered promptly andcompletely with gypsumwallboard.

INSTALLATION

Z FURRING CHANNEL HORIZONTAL INSTALLATION WITHDRYWALL ADHESIVE

DAUB METHOD USING JOINTCOMPOUND

Z FURRING1. Begin application of

Z furring members bypositioning first piecevertically at a corner.Locate the piece on thewall adjacent to the wallbeing insulated first.

2. Insulation thicknessdetermines distance of Z furring web from wallbeing insulated. At theappropriate distance, andwith wide flange pointingtoward applicator, secure Z furring with appropriatefasteners through shortflange. (Note to Specifier:Power driven fasteners arenot recommended for usewith masonry block.)

3. Install 24" wide floor-to-ceiling insulation board,pressed snugly against webof first Z. Install next Z withwide flange overlappingedge of first insulationboard. Fasten to wallthrough narrow flange.

4. Continue in this manner,with Z furring 24" o.c. toend of wall. Locate last Zso that web is located adistance equal to insulationthickness from adjoiningwall. Cut last insulationboard to fit remainingspace.

5. At exterior corner, attachthe Z through its wideflange, with narrow flangeextending beyond thecorner. Begin with anarrow strip of floor-to-ceiling insulation, widerthan insulation thicknessbut not exceeding 3".Continue application offurring and insulationprogressively as describedabove.

6. At windows, doors and trimareas, use wood nailers(nom. 2" wide x insulationthickness plus 1/32"). Usethe nailers also at wall-floorangles to support trim andprovide backing for base.

7. Apply gypsum wallboardwith 1" Type S Screwsthrough flanges of ZFurring, 12" o.c.

LAMINATION1. Masonry or monolithic

concrete shall be dry andfree of dust, loose particles,oil, grease or other foreignmaterial.

2. Joint compound used asadhesive shall be mixed toa consistency thick enoughto allow a 2" daub to stickto the underside of a broadknife held parallel to thefloor.

3. Apply 2" to 2 1/2" diameterdaubs of adhesive 1/2"thick, 16" o.c. in bothdirections to the masonrywall. The adhesive layoutmust provide for a row ofdaubs located a maximumof 2" from board ends, andcare must be exercised tocenter daubs on verticaljoints. No more adhesiveshall be applied to the wallthan will be covered withboard in 15 minutes.Approximate coverage forjoint compound (powder)used as an adhesive is 30-35 lbs./1000 sq. ft.

4. Cut wallboard to allow for1/8" to 1/4" clearancebetween board and floor toprevent potential wicking.

5. Install wallboard by handpressing each board tight tothe wall making certain thatall daubs are in positivecontact with the board.

6. Support boards at eachcorner to keep them fromslipping to the floor by useof a concrete nail driventhrough a small block ofnominal 1" lumber.

7. Butt boards to eachpreviously positionedboard to insure flush joints.

8. If necessary to hold boardsstraight, plumb and inproper alignment, drivemasonry nails throughsmall wood blocks and intomasonry at high pointsonly. After adhesive is dry(24 - 48 hours) removetemporary nails.

9. Fill all holes and treat jointswith tape and jointcompound.

TECHNICAL DATA

PROFORM BRAND SURFACER/PRIMER

ProForm® BRAND Surfacer/Primeris a high-build interior coatingdesigned for use with airlesssprayers. It is used in lieu of askim coat and primer coat toprovide a high quality Level 5finish in one spray applica-tion. This coating hides minorsurface imperfections and isalso an ideal finish for smoothceilings. 5 gallon pail (18.9liters)

can be applied at higher wetfilms (up to 30 wet mils) ifnecessary to mask or reducea greater level ofimperfections. Theapplicator should try toachieve uniform coverageand a slight “orange peel”appearance.

This product can be applied touncoated drywall down to35˚F if surface and airtemperatures do not fallbelow 35˚F for 48 hoursfollowing application.

Allow 4 to 6 hours (70˚F/50%relative humidity) of dryingbefore topcoating withconventional latex paints.Allow 12 to 16 hours ofdrying before topcoatingwith alkyd paints oraromatic solvent basedcoatings such as epoxy. Drytime may vary based ontemperature, humidity orthickness of application. Toachieve a smoother finish,surface may be sanded afterproduct has completelydried. Use nothing coarserthan a 150 grit sandpaper ora 220 grit abrasive meshcloth for sanding.

For use on other substratesthan gypsum wallboard,apply ProFormSurfacer/Primer per previousinstructions over thesesubstrates that are properlyprepared and primed asfollows:

Poured Masonry: Allowpoured masonry to cure aminimum of 30 days. ApplyWater-based Acrylic Primeror Conditioner with highalkali-resistance;

Brick: Allow newly laid brickto cure 30 days. ApplyWater-based, Stain-BlockingAcrylic Primer;

Concrete Block (CMU): Allownewly laid concrete block tocure 30 days. It isrecommended that ProFormSurfacer/Primer be appliedover uncoated concreteblock by “spray, back-roll,and back-spray” method.First, apply by airless spray,then “back-roll” the coatingto force it into any cracks orvoids. Then immediately“back-spray” the coating,and do not engage in anyfurther applicationtechnique;

DESCRIPTION

RECOMMENDATIONS

Surfaces to be coated must bedry, structurally sound andfree of dust, dirt, grease,mildew, efforesence, and allother surface contamination.Stir thoroughly before use.Apply by airless sprayer,suitable for high-buildcoatings. Spray at packagedconsistency. The airlesssprayer should be capable ofdelivering a volume of morethan 1 gallon per minute atup to 3,000 psi. Remove allin-line filters. Use a 3/8" IDhigh-pressure airlessmaterial hose to allow moreefficient material transferand a .021 to .023 airless tipat 2,200 to 3,000 psi. Testthe spray pattern prior toapplication.

To apply to gypsum wallboard,hold spray gunperpendicular to the surfaceapproximately 18" to 24"from surface. Keep the gunat right angles to the surface.The key to a successfulapplication is to apply aneven coat over the entiresurface. This requiresmoving your entire armback and forth, rather thanjust flexing your wrist. Thespray gun should betriggered by turning it onand off with each stroke.This will save paint andavoid paint buildup at theend of each stroke. Overlapeach stroke by 50% over theprevious stroke for uniformpaint thickness. Applyproduct in a crosshatchpattern. This requiresapplying an initial coatspraying fromleft to right toapproximately half thedesired thickness (6-7 wetmils), then crosshatch sprayup and down to desiredthickness (total 12-14 wetmils). Do not apply by rolleror “back-roll” after sprayapplication. This product

Based Stain Blocking AcrylicPrimer can be used ifremaining old paste residueis minimal;

Glossy and All PreviouslyPainted Surfaces: ApplyInterior Alkyd (oil-based)Enamel Undercoater orWater-Based BondingPrimer;

Incidental Wood Surfaces:Apply Interior Alkyd (oil-based) Enamel Undercoateror Water-based AcrylicPrimer with tannic-acidbleed resistance.

DECORATIONSurface may be painted afterovernight drying. Adherestrictly to appropriate manu-facturer’s directions forsurface preparation, painting

and decorating. Suchmanufacturers should beconsulted if decoratingproblems arise.

LIMITATIONS• Dries to a slight “orange

peel” appearance.• For use by professionals.• Experimentation and test

application are recommend-ed.

• Protect from freezing andexposure to extreme heatand direct sunlight, condi-tions that will cause prema-ture aging of the product.

• Do not apply by roller or“back-roll” after spray appli-cation on gypsum wall-board and most othersubstrates.

PERFECT SPRAY EM/HF TEXTURE APPLICATIONTexturing can be, depending

on desired pattern, a single-or multiple-coat operationusing a spray texture gun fedby a piston or Moyno-typepump. An Orange PeelFinish is achieved with ahigh atomizing pressure andthin mix. A Spatter Finishuses a low atomizingpressure and heavy mix.Other finishes can becreated by combiningmethods in two coatoperations or trowelingspatter patterns before fullydried (Spatter Knockdown).

CAUTION: Where a vaporretarder has been installedabove a gypsum boardceiling, adequate ventilationmust be provided during thedrying period. Thisprecaution is necessary inorder to minimize thepossibility of gypsum boardsagging due to moistureabsorption.

NOTE: Surfaces must beprimed with a sealingprimer.

APPLICATIONGYPSUM WALLBOARD: Surfaces, including joint-treated

areas, must be smooth,clean and dry. First apply acoat of sealing primer.Allow primer to drythoroughly, and maintainadequate drying conditionsafter application. Primer is tominimize sagging of gypsumwallboard and discolorationor difference in sheen onceiling surface. Add drytexture to water. Use apiston pump or Moyno-typepump with a texture gun.Minimum 3/4" I.D. materialhose. A hopper-type gun

with adequate air supply isalso suitable. Typicalcoverage is 8-10 sq. ft. perlb. for aggregated and 10-30lb. for nonaggregatedtextures. Mask appropriateareas before spraying andpromptly remove oversprayfrom unprotected surfacesafterward. Follow theinstructions of the sprayequipment manufacturer foradjusting controls andcleaning. If a second coat isdesired, allow the first coatto dry thoroughly.

NOTE: Gypsum wallboardceiling surfaces to bedecorated with water-thinned spray texture shallbe 1/2" or 5/8" thick andapplied perpendicular to theframing. Framing shall notexceed 16" o.c. for 1/2"Regular Wallboard and 24"o.c. for 1/2" High StrengthCeiling Board and 5/8"wallboard.

CONCRETE: Allow concrete to cure for at

least 28 days. Clipprotruding wire ends andspot with rust-inhibitiveprimer. Remove all form oil,grease and dirt, or any looseor water-soluble material.Grind down any formridges, and level anyremaining unevenness withSta-Smooth JointCompound. Apply a coat ofalkali-resistant, sealingprimer over the entiresurface to be textured.

AVAILABILITY: Contact yourarea National Gypsum salesrepresentative for textureproduct availability.


syn telegraphing.Drywall Primer: A paint

material specificallyformulated to fill the poresand equalize the suctiondifference between gypsumboard surface paper andthe compound used onfinished joints, angles,fastener heads, andaccessories and over skim coatings.

Skim Coat: A thin coat of jointcompound,or a materialmanufactured especially forthis purpose, applied overthe entire surface to fillimperfections in the jointwork, smooth the papertexture, and provide auniform surface fordecorating. Excesscompound is immediatelysheared off, leaving a filmof skim coating compoundcompletely covering thepaper.

Spotting: To cover fastenerheads with jointcompound.

Texture: A decorativetreatment of gypsum boardsurfaces.

Texturing: Regular or irregularpatterns typically producedby applying a mixture ofjoint compound and water,or proprietary texturematerials including latexbase texture paint, to agypsum board surfacepreviously coated withprimer/sealer.

LEVELS OF FINISHThe following levels of finish

are established as a guidefor specific finaldecoration. The minimumrequirements for each levelshall be as describedherein.

LEVEL 0No taping, finishing, or

accessories required.This level of finish may be

useful in temporaryconstruction or wheneverthe final decoration has notbeen determined.

LEVEL 1All joints and interior angles

shall have tape set in jointcompound. Surface shallbe free of excess jointcompound. Tool marks andridges are acceptable.

Frequently specified inplenum areas aboveceilings, in attics, in areas

where the assembly wouldgenerally be concealed, or in building servicecorridors, and other areasnot normally open topublic view. Accessoriesoptional at specifierdiscretion in corridors and other areas withpedestrian traffic.

Some degree of sound andsmoke control is provided;in some geographic areasthis level is referred to as“fire-taping.” Where a fire-resistance rating is requiredfor the gypsum boardassembly, details ofconstruction shall be inaccordance with reports offire tests of assemblies thathave met the fire-ratingrequirement. Tape andfastener heads need not becovered with jointcompound.


shall have tape embeddedin joint compound and wiped with a joint knifeleaving a thin coating ofjoint compound over alljoints and interior angles.Fastener heads andaccessories shall becovered with a coat of jointcompound. Surface shallbe free of excess jointcompound. Tool marks andridges are acceptable. Jointcompound applied over thebody of the tape at the timeof tape embedment shall beconsidered a separate coatof joint compound andshall satisfy the conditionsof this level.

Specified where water-resistant gypsum backingboard (ASTM C 630) isused as a substrate for tile; may be specified ingarages, warehouse storageor other similar areas wheresurface appearance is notof primary concern.


shall have tape embeddedin joint compound and oneadditional coat of jointcompound applied over alljoints and interior angles.Fastener heads andaccessories shall becovered with two separatecoats of joint compound.All joint compound shallbe smooth and free of toolmarks and ridges. Note: It

is recommended that theprepared surface be coatedwith a drywall primer priorto the application of finalfinishes. See painting/wallcovering specificationin this regard.

Typically specified inappearance areas whichare to receive heavy- ormedium-texture (spray orhand applied) finishesbefore final painting, orwhere heavy-gradewallcoverings are to beapplied as the finaldecoration. This level offinish is not recommendedwhere smooth paintedsurfaces or light to medium wallcoverings are specified.


shall have tape embeddedin joint compound and twoseparate coats of jointcompound applied over allflat joints and one separatecoat of joint compoundapplied over interiorangles. Fastener heads andaccessories shall becovered with three separatecoats of joint compound.All joint compound shallbe smooth and free of toolmarks and ridges. Note: It is recommended that theprepared surface be coatedwith a drywall primer prior to the application of finalfinishes. See painting/wallcovering specificationin this regard.

This level should be specifiedwhere flat paints, lighttextures, or wallcoveringsare to be applied.

In critical lighting areas, flatpaints applied over lighttextures tend to reducejoint photographing. Gloss, semi-gloss, andenamel paints are notrecommended over thislevel of finish.

The weight, texture, andsheen level of wall-coverings applied over thislevel of finish should becarefully evaluated. Jointsand fasteners must beadequately concealed if thewallcovering material islightweight, containslimited pattern, has a glossfinish, or any combinationof these finishes is present.Unbacked vinyl wall-coverings are notrecommended over thislevel of finish.

The following has beenexcerpted from a consensusdocument prepared by theAssociation of the Wall andCeiling Industries-International (AWCI),Ceilings & Interior SystemsConstruction Association(CISCA), GypsumAssociation (GA), andPainting and DecoratingContractors of America(PDCA) as a guide togypsum board finishing.The members of theseinternational tradeorganizations are dedicatedto providing the bestpossible job for the mostreasonable cost. Byincorporating theappropriate sections of thisrecommended specificationinto the project documents,the architect, generalcontractor, and buildingowner can better anticipatethe final appearance of thedecorated wall and ceilingsystem.

This has also been issued bythe Gypsum Association asdocument GA-214.

SCOPEThis recommended

specification describesvarious levels of finish ofgypsum board surfacesprior to the application of specific types of final decoration. Therecommended level offinish of gypsum board walland ceiling surfaces varieswith the final decoration tobe applied and can also bedependent on their locationin a structure and the typeof illumination striking the surface. Eachrecommended level offinish is described withtypical applications.

TERMINOLOGYThe following definitions

are applicable to thisdocument.

Accessories: Metal or plasticbeads, trim, or mouldingused to protect or concealcorners, edges, orabutments of the gypsumboard construction.

ManufacturerRecommendations. Therecommendations ofindividual manufacturers ofgypsum board, joint tapesand compounds,accessories, drywallprimers, wallcoverings,adhesives, texturematerials, and paints mayvary from what isrecommended herein andas such are not a part ofthis recommendedspecification.

DRYWALL PRIMERApplied as a first coat to the

entire prepared gypsumboard surface with brush,roller, or spray, prior todecoration. Where finalappearance is critical, theapplication of high quality,high solids, drywall primerwill minimize mostdecorating problems.

For finish paints: A goodquality, white, latex drywallprimer formulated withhigher binder solids,applied undiluted, istypically specified for newgypsum board surfacesprior to the application oftexture materials and gloss,semi-gloss, and flat latexwall paints.

An alkali and moisture-resistant primer and a tintedenamel undercoat may berequired under enamelpaints. Consult with thefinish paint manufacturerfor specificrecommendations.

For wallcoverings: White, self-sizing, water base,“universal” (all purpose)wallcovering primers haverecently been introducedinto the marketplace for useon new gypsum boardsurfaces. These productsare claimed to minimizedamage if wallcoveringsare subsequently removed,bind poor latex paint, allowhanging over glossysurfaces and existing vinyls,hide wall colors, and to bewater washable.

TEXTURINGTexture material is applied by

brush, roller, spray, ortrowel, or a combination ofthese tools, depending onthe desired result. Texturedwall surfaces are normallyoverpainted with thedesired finish; overpaintingof textured ceiling surfacesmay not be deemednecessary where anadequate amount ofmaterial is applied to

shall have tape embeddedin joint compound and twoseparate coats of jointcompound applied over allflat joints and one separatecoat of joint compoundapplied over interiorangles. Fastener heads andaccessories shall becovered with three separatecoats of joint compound. Athin skim coat of jointcompound, or a materialmanufactured especially forthis purpose, shall beapplied to the entiresurface. The surface shallbe smooth and free of toolmarks and ridges. Note: It isrecommended that theprepared surface be coatedwith a drywall primer priorto the application of finishpaint. See paintingspecification in this regard.

This level of finish is highlyrecommended where gloss,semi-gloss enamel ornontextured flat paints arespecified or where severelighting conditions occur.

This highest quality finish isthe most effective methodto provide a uniformsurface and minimize the

possibility of joint photo-graphing and of fastenersshowing through the finaldecoration.

COMMENTSCritical (Severe)

Lighting Areas.Wall and ceiling areas

abutting window mullionsor skylights, long hallways,or atriums with largesurface areas flooded withartificial and/or naturallighting are a few examplesof critical lighting areas.Strong sidelighting fromwindows or surface-mounted light fixtures mayreveal even minor surfaceimperfections. Light strikingthe surface obliquely, at avery slight angle, greatlyexaggerates surfaceirregularities. If criticallighting cannot be avoided,the effects can beminimized by skim coatingthe gypsum board surfaces,by decorating the surfacewith medium to heavytextures, or by the use ofdraperies and blinds whichsoften shadows. In general:gloss, semi-gloss, andenamel finishes highlightsurface defects; textureshide minor imperfections.

Gypsum drywall shaftconstruction has becomethe preferred alternative totraditional masonry shafts.One-inch Shaftliner boardwas developed as alightweight, easy-to-installreplacement for masonry inthe interior core ofbuildings for shaftwalls,stairwells, other verticalchases and mechanicalenclosures. Shaftliner board is also used as acomponent of 2" solidpartitions, and areaseparation walls with alayer of 1/2" Regular orFire-Shield Wallboardattached to each side.

Historically, heavy masonryweighing 20 to 45 lbs. persquare foot was used forshaftwall construction.With the use of Shaftliner,shaftwall assemblies weighin at a remarkably low 10to 13 lbs. per square foot.

The benefits of gypsumdrywall shaft systems go farbeyond the difference inweight alone. The corewall of a shaft can beinstalled from the exteriorof the shaft and requires no scaffolding. Erection is speedy and clean.Shaftliner also providesexcellent sound controland can achieve the fireratings necessary for today’sbuilding construction. Bestof all, gypsum shaftwallsystems are moreeconomical than masonryshaft construction.

National Gypsum producesShaftliner board with greenmoisture-resistant paper orpurple moisture/mold/mildew resistant paper onboth sides with a bevelededge configuration allowingfor simple installation intothe tabs of the I-Stud, anintegral part of theShaftwall System.

The I-Stud Cavity Shaftwall isa nonload-bearing drywallpartition system and ismade up of two basiccomponents, gypsum boardand metal framing.

Gypsum board includes 1"Fire-Shield Shaftliner or 1"Fire-Shield Shaftliner XPpanels, 1/2" Fire-Shield Cand 5/8" Fire-Shieldgypsum board face panels.The metal framing includesI-Studs with integral tabswhich hold the panels inplace and J Track forrunners at top and bottom,as well as vertically atpartition ends and to frameopenings.

The I-Stud System wasdeveloped to encloseelevator shafts and othervertical chases in buildingswhere it is advantageous toerect these walls from oneside only and where fireresistance and resistance toair pressures are required.

Lightweight. The I-StudShaftwall System is verylightweight compared toconventional shaftwalls,weighing approximately 10lbs. per sq. ft. of wall whenfinished with two layers of 1/2" Fire-Shield CWallboard.

Economical. Shafts can bequickly enclosed with I-Studs and Shaftliner undermost conditions in whichinstallers can work, wellbelow temperaturelimitations for finishwallboard applications.

Practical. The 1" Shaftliner is faced with light greenmoisture-resistant paperand Shaftliner XP is facedwith purple moisture/mold/mildew resistant paper forprotection against weatherduring installation.

FUNCTION AND UTILITYLoading Performance.

Although the I-StudShaftwall System is non-load-bearing, this Systemhas been designed andtested to withstand positiveand negative air pressureforces exerted by high-speed, high-rise elevators.

Fire Resistance. The I-StudShaftwall System has beenfire tested and has achievedfire resistance ratings of 1 and 2 hours. Allcomponents arenoncombustible. Refer to pages 16 and 17.

25 GA (.020" minimum steelthickness) J Track exceeded2,000,000 lateral loadoscillation cycles in a testconducted to duplicate thepositive and negativepressures created as

elevator cabs rise anddescend in a shaft.

Sound Transmission. STC ratings of 40 to 51 havebeen achieved in testsconducted in accordancewith ASTM E 90. Refer to pages 16 and 17.

LIMITATIONS1. Nonload-bearing.2. This System should not be

RECOMMENDATIONS

FRAMING AND SHAFTLINERCAVITY SHAFTWALL1. Locate and lay out partition

floor and ceiling lines toassure plumb partition.

2. Insure accurate studspacing to maintainwallboard face layermodule.

3. Position top and bottom JTrack with long leg towardthe shaft along ceiling, floorand vertically at columnand/or wall where erectionof Shaftwall will begin.Attach with power drivenfasteners 24" o.c. max.

4. Frame all openings cut into I-Stud partitions for ducts,etc. with J Track as shownin accompanying details toprotect cut gypsum coreedges and to provideresistance to bending andother stresses.

5. Cut shaftliner panels 1" lessthan ceiling height andinstall first by placingoutside vertical edgeagainst long leg of verticaltrack, plumb and attachwith Type S 1 5/8" Screws24" o.c.

6. Place I-Studs within flangesof floor and ceiling trackand rotate into place. Slidestud tabs snugly over edgeof Shaftliner previouslyinstalled.

7. Install next Shaftliner panelbetween tabs of I-Studs.Continue in this manneruntil end of partition run.Occasionally checkspacing of I-Studs tomaintain 24" module.

8. At end of run, cut vertical J Track at least 2" short ofpartition height. CutShaftliner 1/4" less thanremaining width ofpartition and 2" short of full height. Lay piece ofShaftliner 2" wide x lengthof opening in floor track assupport for last Shaftlinerpanel. Fit cut edge ofShaftliner into vertical trackand, holding Shaftliner andtrack together, slide paper

bound edge of Shaftlinerinto I-Stud. Align last paneland fasten the vertical trackwith appropriate fasteners24" o.c. max. FastenShaftliner to vertical trackwith 1 5/8" Type S or S-12Screws 24" o.c. Seedrawing on page 124 foralternate detail.

9. Locate any shaftliner endjoints within the upper andlower third points of wall.Stagger joints in adjacentpanels to avoid continuoushorizontal joint. Shaftlinerpanels shall be of sufficientlength to engage aminimum of two I-Stud tabs along each edge.

WALLBOARDApply first layer of 1/2" Fire-

Shield C (5/8" Fire-Shield)Gypsum Wallboardhorizontally to face of I-Studs with screws spaced24" o.c. Apply second layer vertically with screwsspaced 12" o.c. (Use 1"Type S Screws on firstlayer, 1 5/8" Type S Screwson second layer for 25gauge nominal framing.)(Use 1" Type S-12 Screwson first layer, 1 5/8" Type S-12 Screws on secondlayer for 20 gauge orheavier framing.) Stagger allvertical and horizontaljoints. For proper jointtreatment, maintainuniform room temperaturebetween 50˚F and 70˚Fduring cold weather. Treatjoints of face layer withtape and joint compound.

CAULKINGCaulk I-Stud Cavity Shaftwall

with acoustical sealantwherever the wall isenclosing shafts wherepositive or negative airpressure exists. Caulkperimeter of wall and atany other place wherevoids create the possibilityof moving air causing dustaccumulation, noise orsmoke leakage. Caulkingshall be done incompliance with detailsspecified by thearchitect/designer.

AIR SHAFTSThe System is not designed to

serve as an unlined air

supply duct. Caulking isrecommended atperimeters and penetrationswherever the I-Stud Systemis used to enclose elevatorsor other shafts wherepositive or negativepressures will exist. Thecontractor installing thisSystem shall caulk incompliance with detailsspecified by the architect/designer. Proper caulkingwill seal perimeters andpenetrations to minimizeair noises and dustassociated with airmovement.

FRAMING FOR OPENINGSFrame doors, borrowed lights

and duct openings with JTrack. Use adequatestructural support foropenings over 48" wide.For openings up to 48"wide, use vertical J Trackon either side of openings.For head and sill ofopenings, place J Trackhorizontally acrossopenings. Cut J Track about12" longer than openings.Then cut flanges and foldback to nest over vertical J Track and fasten webs orflanges with two 3/8" Type S or 1/2" Type S-12Pan Head Screws perconnection. When nesting J Track to J Track, cut offshort flange of horizontal J Track so it will fit oververtical J Track.

CALL BOXES ANDPOSITION INDICATORSProtect call boxes, position

indicators and fireman’sswitches as shown indrawings on page 126.

CHASESWhen possible, locate all

vertical rise, conduit, stairhangers, etc., within wallcavity. If the cavity in the 2 1/2" stud wall is not ofsufficient width, the 4" or 6" studs can be used forchases or erect chase wallsas shown on page 120.

ELEVATOR DOORSElevator door frames must be

braced and supportedindependently of theshaftwall. However,shaftwall must be tied into

elevator door frames bybeing attached to jamb andanchor clips with pan headscrews. The 3" leg, nominal20 gauge J Track shall beused at the juncture of theelevator door frame and theI-Stud System. Seedrawings on pages 124 and125 for details.

Door frames (other thanelevator door frames)should be formed from notless than 18 gauge steel,shop primed, with throatopenings accurately formedto the nominal wallthickness plus 3/32".Frames must have trimreturns not less than 7/16"in width to bear flushagainst the wallboardsurface. Floor anchor platesshould be 14 gauge (min.)steel, firmly welded toframes and designed withnot less than two anchorholes 3" o.c. minimum toprevent frame rotation.Anchor plates should besecurely fastened to thefloor with power drivenfasteners having minimumdimensions of 3/16"diameter and 3/4" length.The type and size offastener is dependent onjob conditions, type ofconcrete or steel framing,etc., and must be sufficientto provide rigid, continuousanchorage to the frames.Jamb anchor clips shouldbe formed from 18 gauge(min.) steel, and welded tojambs to provide adequateanchorage to jamb framingas shown on details.Elevator door frames mustbe fastened to andsupported by the buildingstructure, separately framedand independent of thepartition. They shall besecurely anchored to thesills and to the buildingstructure or to the tracksupports. Anchors orfastenings to suit the wallconstruction are requiredand shall be not more than2' apart. See details onpage 124 and 125 forconnection of partition and elevator door frames.

RECOMMENDATION

*When a 3/4" air space cannot be maintained between the H-Stud assembly and adjacent framing members, 1/2" Fire-Shield C Gypsum battens arerequired to cover H-Studs and H-Stud Track.

Order H-Studs and 1" Fire-Shield Shaftlineraccording to the followingoutline:

Basement wall section –length equal to distancefrom foundation floor toapproximately 3" abovefloor line of first floor.

Intermediate floors – lengthequal to distance betweenfloor lines.

Topmost floor – length toextend to top of parapetwall or to roof inter-section, depending on detail.

BASEMENT WALLINSTALLATION1. Beginning at foundation

floor, attach 2" H-StudTrack to concrete withpower-driven fastenersspaced 24" o.c. Applyacoustical sealant alongedges of track at floor line.

2. Install H-Stud Track onfoundation walls whereArea Separation Wallintersects, if applicable.Fasten with power-drivenfasteners 24" o.c. Caulkedges as with floor track.

3. At intersection offoundation or exterior walland Area Separation Wallbegin erecting by insertingfirst layer of 1" Shaftliner

into floor and wall track.Insert second layer back-to-back with first and seatinto floor and wall track.Shaftliner and studs maybe set into position fromthe basement floor or feddown through the spaceprovided in the woodframing from the floorabove.

4. Making sure that bothpieces of Shaftliner areseated all the way into thefloor and wall tracks andthat their edges are flush,insert an H-Stud into thefloor track and engage theH-Stud legs over the longedges of the Shaftlinerboards. Seat the H-Studfully so the board edgescontact the stud web.

5. Continue in this manner,erecting two thicknessesof Shaftliner, and installingthe legs of the H-Stud overthe Shaftliner edges untilwall is completed. Again,make sure all studs andboards are tightly pushedtogether. Screw studs tofloor track with Pan Head3/8" Type S Screws.

6. If the Area SeparationWall terminates at afoundation wall, the lasttwo Shaftliner boards willhave to be inserted fromthe floor above. Boardsare pushed down into thechannel formed by theprevious H-Stud’s legs andthe legs of the wall track.

7. If the Area SeparationWall terminates at or pasta framed wall, insert thelast boards conventionallyand cap the end of theArea Separation Wall with2" H-Stud Track. Screwflanges of floor track toflanges of terminationtrack.

8. The top edge of theerected wall is thencapped off by placing 2"H-Stud Track over studsand boards. Screw thetrack to each H-Stud with3/8" Type S Pan HeadScrews. Locate tracksplices at a stud so bothtrack ends can be screw-attached to the stud.

9. Attach studs to adjacentwood framing with ASWClips. Secure the clips tothe studs with one 3/8"Type S Pan Head Screwthrough the short leg ofthe clip. Secure clip towood framing with one 8dnail or 1 1/4" Type WScrew through the longleg of the clip. Clips areattached to wood framingat each vertical steel-wood framingintersection. The ASWClips may be attacheddirectly to the steel studsor through the wallboardbatten face into the studs.

10. A minimum 3/4" air spaceshall be maintainedbetween the H-Stud

assembly and anyadjacent framingmembers.* When a 3/4" air space cannot bemaintained, gypsum boardbatten strips are installedover H-Studs and H-StudTrack on both sides of thewall. 3" wide battens areinstalled over H-StudTrack at foundation androof. 6" battens are screw-attached to H-Studs with1" Type S screws spaced12" o.c. screwed intoalternate legs of H-Stud.Battens are cut from sheetsof 1/2" Fire-Shield CGypsum Board.

INSTALLATION AT INTERMEDIATE FLOORS AND AT ROOF1. Attach 2" H-Stud Track to the already installed capping track

of the lower floor’s wall. This back-to-back track installationallows the Area Separation Wall to be erected one floor at atime. Secure the two tracks together with two 3/8" Type S Pan Head Screws 24" o.c. Stagger back-to-back track joints a minimum of 12".

2. Erect Shaftliner and H-Studs in the same manner as for thebasement wall, steps 4-10, except that starting and endingprocedures vary depending on the exterior wall intersectiondetail. See drawing details.

3. At roof intersection the walls are capped-off with H-StudTrack. Track is fastened to each stud with 3/8" Type S PanHead Screws. H-Studs are fastened to wood framing withASW Clips. The specific framing procedure varies accordingto roof junction details as illustrated in drawings.

4. Fire blocking must be provided to completely fill the wallcavity at the intermediate floor construction as shown indrawings. Mineral wool or gypsum board filler may be used.

INTERIOR FACINGS1. 2" H-Stud Area Separation Wall can be finished in a variety of

ways depending on wall installation. For load-bearingapplications, wood stud walls meeting required codes mustbe erected flanking the Area Separation Wall. Stud walls arethen finished in whatever method is specified. For nonload-bearing applications, finished wall may be of any typemeeting local codes including exposed Shaftliner and battenswhere appearance is not critical.

The Durasan line consists ofDurasan Brand VinylCovered Wall Boards. AllDurasan Wall Boards can beapplied directly to studs oras a finish layer over gyp-sum wallboard. DurasanBoards are especially suitedfor most demountable parti-tion systems. BecauseDurasan is prefinished, it isgenerally less expensive toinstall than building a walland then applying a wallcovering material.

Durasan is the registered trade-mark for National GypsumCompany prefinished gyp-sum wall boards. This quali-ty paneling combines thetime-proven characteristicsof gypsum wallboard withthe beauty, colors, textures,and durability of a widevariety of vinyl coverings.

Durasan can be toploaded ongypsum trucks and is avail-able from all National Gypsum plants. Some plantsmaintain inventories of the most popular colors and patterns which are availablefor immediate shipment

PHYSICAL PROPERTIES

Thickness: Available 1/2" thickas a standard product. Fire-Shield Durasan is also avail-able as a special order itemin 1/2" or 5/8" thicknesses.

Sizes: Durasan Boards are typi-cally 4' wide. For informa-tion on widths narrowerthan 4', consult yourNational Gypsum CompanySales Representative.Normal lengths are 8', 9'and 10'. Other lengthsbetween 8' and 14' areavailable on special order.

Edges: The long edges of allDurasan Wall Boards arewrapped with a vinyl filmcovering. Board edges arebeveled.

Vinyl Covered Durasan WallBoards comply with ASTMSpecification C 960 andFederal Specification SS-L-30D. Approved by Board ofStandards and Appeals foruse in New York City underCalendar Nos. 709-39.

NONCOMBUSTIBLE

Durasan Gypsum Wallboard isconsidered noncombustible,since it meets the followinggenerally acceptedrequirements:

1. A structural base of non-combustible material suchas gypsum.

2. A surface material not over1/8" thick which has a flamespread of not over 50.

DURASAN BRAND PREFINISHED GYPSUM WALLBOARD

LIMITATIONSHigh HeatDurasan Wall Boards have the

same limitations regardingheat as regular gypsumwallboard and should notbe used in areas where sur-face temperatures willexceed 125˚F.

Durasan Wall Boards are notsuitable for use behindstoves where direct heat orsteam could affect theboard covering.

Moisture ConditionsDurasan Boards should not be

used around bath tubs, inshower enclosures or inareas where boards will besubject to free moisture.

When Durasan Boards abutconcrete floors and/or ceil-ings, cut board to allow for1/8" to 1/4" clearancebetween board and floorand/or ceiling to preventpotential wicking.

Treated LumberIf Durasan Boards will be

applied over treated lum-ber, tests should be con-ducted prior to applicationto be sure the chemicaltreatment of the wood doesnot affect the bond or colorof the board covering.

Masonry WallsDo not apply Durasan Boards

over wet or damp masonrywalls. Mildew or stainingproblems could result if thewalls are not dry or will notremain dry.

Trim ApplicationPlastic, wood or metal trim

must be applied at bothfloor and ceiling.

Trim should be applied care-fully to Durasan Boards toavoid creating excessivepressures which might latercause delamination of thecovering.

Color accuracy of these Dursan Vinyl patterns is limited in printing.Therefore, it is suggested that reference also be made to actual samples inthe Durasan Pocket Selector. Contact your National Gypsum SalesRepresentative for Selectors and for information on Durasan Vinyl deliveryschedules in your area.

COMMON STAINING MATERIAL RECOMMENDED SOLVENT

Grease, tar, shoe polish, Kerosene or mineral spiritslipstick, oil paints

Nail polish Denatured alcohol

Ink (regular or ballpoint) 1:1 mixture—Denatured alcohol and “Aromatic 150”

“Aromatic 150” is a proprietary solvent manufactured by Exxon Company USA.

PAINTINGDurasan is a factory-finish

However, if desired, Durasancan be satisfactorily paintedwith the following products:

1. Two coats of an alkyd orlatex semigloss enamel.

2. Oil primer with finish coatof oil paint or flat latex.

3. Two coats of flat oil paint.PATCHINGIt is suggested that scraps of

Durasan be saved in casepatching a damaged area isnecessary. When patchingsmall rips or tears, removethe vinyl film from aDurasan scrap. Place thefilm over the damaged areaand, using a razor blade orvery sharp knife, makestraight cuts through bothlayers of film. The damagedfilm underneath is thenremoved and the patchcemented in its place with agood quality vinyl-to-vinyladhesive.

WALLCOVERINGMatching Durasan in 30-Yard RollsFabric-backed vinyl film is

available in most Durasanpatterns, colors and texturesfor field application to pro-vide a close, commercialcolor match for use oncolumns, curved surfaces orwhere extensive cutoutswould make Durasanboards difficult to use.Because field-applied vinylis fabric-backed, theDurasan Boards and the comple-mentary vinyl roll goodsmay vary slightly in colorand texture.

Durasan fabric-backed wall-coverings meet or exceedthe criteria outlined inFederal Specification CCC-W-408B.

Color VariationSince manufacturers of the

laminate used on DurasanBoards finish to a commer-cial color match, minorcolor variations are possi-ble. Therefore, care shouldbe taken during applicationto ensure that boardsapplied on single walls orvisual areas are colormatched to minimize anysuch variations in the lami-nate.

CLEANINGComplete removal of dirt,

stains and marks is easier ifcleaning action is startedbefore staining material hasdried, cured or set.

To remove most common dirtand marks, simply rublightly with a moistenedcloth, sponge or soft hairbristle brush, using a mildsoap, detergent or non-abrasive cleaner. Thenrinse with water and wipe dry.

More stubborn stains can besafely removed by wipingaway excess material,scrubbing the stained areawith a stiff bristle brushwetted with appropriatesolvent as listed in chart,and quickly wiping drywith a clean cloth.

Caution: The use of strongorganic solvents (such asketones), harsh abrasivecleaners or steel wool arenot recommended. Thesematerials may causedulling, discoloration, softening and other permanent damage to the vinyl surface.

Some proprietary solventcleaners used for fabricspot stain removal mayremove the vinyl surfaceoverprint pattern.

If the suitability of any clean-ing agent is unknown,check its effect on theDurasan surface in a hid-den area or on a scrappiece before attempting to remove a field stain.
