AQUA STOP

TROWEL APPLIED,CEMENTITIOUSWATERPROOFINGMEMBRANE

AQUA STOP is a thin, load bearing waterproofingsystem which offers high bond strength and chemi-cal resistance. It has a built-in resiliency com-bined with load bearing quality that enables themembrane to absorb physical shocks and elimi-nate cracking of the joints under wheeled traffic.Unprotected Aquastop membrane takes light foottraffic and is suitable for terraces, sundecks, pa-tios, roof deck and similar outdoor areas.

RECOMMENDED USES

l Designed for under water use- tank linings,kitchens, swimming pools, fountains.

l Under thin set ceramic tiles, pavers, stone,marble, indoor or outdoor carpeting, syn-thetic grass and concrete toppings.

l Can be used over existing ceramic tiles orterrazzo.

ADVANTAGESHigh strength and heavy duty waterproofingSeamless.Resistant to physical and thermal shocks.Chemical resistant, non-flammable and non-toxic.Handles the differential movement between tilesand concrete.

INSTALLATION INSTRUCTIONSPreparationThe surface to be waterproofed should be cleanand free from dirt, oil, grease, etc. Dry or dustyslabs should be dampened and the excess waterswept off. Installation may be made on a dampsurface.Plan the sequence of placement. Pre-cut the re-inforcing fabric into lengths allowing 2” (50 mm)for overlap and a minimum of 4” (100 mm) at eachend for flashing cove base upto the wall. Roll upthe cut fabric, so that each piece of fabric may beproperly placed and unrolled into wet waterproof-ing paste.Examine the floor surface for cracks and coldjoints which will require additional layers of rein-forcing fabric. Use a 6” (150 mm) wide strip of fab-ric and waterproofing paste to reinforce all cracksand joints prior to waterproofing application. Ap-ply an extra layer of fabric and waterproofing pasteto flash into drains, at outside corners and at ar-eas which are subjected to stress or movement.Floor surfaces that require patching, levelling orpitching to drains shall be prepared prior to theplacing of the membrane. All patching and level-ling should be carried out using CEMMIX LATEXADDITIVE with a 1:3 mixture of Portland Cementand sand.

MixingAdd the powder component to the latex liquid andmix either by hand or conventional mixer of therotating drum type. Mixing can also be carried outusing an electric slow speed drill. 13 mm paddleshould be attached. Keep mortar as stiff a pos-sible for the intended use. Over mixing should beavoided - it will entrap air. Total mixing time perunit of AQUA STOP should not exceed five (5)

CMCICMCIminutes. Do not add water to the mix.

ApplicationUse a trowel or squeegee to apply thin layer(Approx. 1.5 mm) of waterproofing mortar slightlywider than the width of the fabric. Spread the pastethen immediately unroll and embed the reinforc-ing fabric into the wet mortar. Immediately spreadanother thin layer of waterproofing mortar on topof the fabric until it completely and uniformly sealsthe fabric. Lap the fabric 2” (50 mm) at seams.Be sure the mortar completely covers and sealsthe fabric with a smooth surface free of pinholesand voids.The same procedure applies to cover horizontaland vertical applications.

CuringAQUA STOP is self curing system. However,when areas are exposed to sunlight, rapid airmovement or very warm temperature cover withwet burlap or a fog mist spray for at least 24 hours.

PACKAGINGl 20 Liters waterproofing liquidl 50 Kg waterproofing powderl 20 Sq. meter reinforcing fabric.

COVERAGEEach unit of AQUA STOP will cover an area ofapprox. 15 sq. mtrs. at 3mm thickness.

PRECAUTIONS & LIMITATIONSl No sealers or curing compounds shall be

used on concrete slabs which are to receiveAQUA STOP waterproofing membrane.

l Application of AQUA STOP should not bemade when air or surface temperature isbelow 7 deg. C.

l Allow the membrane to cure for at least 7days.
