estimating wallcoverings

wall preparation

•walls must be clean and dry—free from grease, dirt, body oils & old wallpaper•determine who will do prep•nail holes need to be filled•walls need to be smooth•unsealed walls need to be primed and sealed•determine appropriate sizing to use•paint trim before hanging wallcovering

estimating materials

how to measure:•use steel measuring tape—25 ft. long x ¾ in. wide—always measure in inches•measure length then width of each wall•put measurements on rough sketch/ exploded floor plan•measure windows, doors & other openings—add measurements to drawing•follow-up measure by wallpaper hanger

estimating materials

estimating wallpaper:•consulting manufacturers charts—

• fastest & easiest; works well for average, box-shaped rooms

•strip method—• requires counting of actual strips used• chopped-up wall space, cathedral ceilings,

commercial installations•square footage method—

• works for almost any wall surface

estimating materials

estimating wallpaper: european, american-made,

oriental, commercial

double roll—five

full strips (with 8 ft. ceiling)

estimating materials

American-made wallcoverings (27-inch roll)

•standard formula—no pattern repeat•measure perimeter of room•multiply by ceiling height•divide by 30•deduct 2 single rolls for every 4 ordinary openings

example: room is 12 ft x 14 ft w/8 ft ceilings room has 2 windows & 2 doors

12’+14’+12’+14’ = 52’x 8’ ceiling= 416’/30 = 14 rollsdeduct 2 rolls for openings = 12 rolls

estimating materials

European wallcoverings (20-22 inches wide)

•estimate square footage, divide by 22•more rollage is needed than when using American-made

Oriental wallcoverings (36-inches wide)

•estimate square footage, divide by 36

commercial wallcoverings (54-inches wide)

•can be done by strip method or square footage method•sq ft method must be divided by 13.5 to convert to linear yards

estimating materials

pattern repeats•lengthwise/crosswise measurement of one design motif to where that same pattern is again repeated•straight—straight across match•half-drop—same height pattern motif halfway in between two other repeats•random—does not present matching problem—advisable to reverse strips for grasscloth

estimating materials: rollage chartplain or solid coverings

time estimating•realistic time-estimate only given after wallcovering is ordered•call paper hanger to set installation date—ask for estimate of time

cost estimating•materials—vary GREATLY in cost•hanging labor—charged per roll

choosing a paper hanger

•have hangers in mind before you need them•range from inexpensive part-timers to seasoned professionals•get referrals from other designers•set up appointments and interviews—see their work & call past clients•always get a signed work order to avoid misunderstandings
