STUHR CP ELASTIC WA-158 is an aqueous acrylic copolymer emulsion for mixing with cement, adhesive mortars and smoothing mortars to provide a waterproof or water-resistant smoothing layer. High performance polymer that can be aggregated into regularizing mortars, adhesive mortar and cement.
It is indicated as a waterproofing membrane for wet and wettable areas such as swimming pools, balconies, baths and reservoirs. It is also suitable for waterproof subfloor adhesion bridge, subfloor mortar additive or waterproof bars, adhesive mortar additive for sealing properties (applied as polymeric mortar) and flexible mortar for laying mortar.
Method | Test | Unity | Result |
---|---|---|---|
ASTM E 70 | pH | 7 - 10 | |
ME-013 | Viscosity | cP | 5.000 - 10.000 |
ASTM D 792 | Density | g/cm3 | 0,90 - 1,10 |

SURFACE PREPARATION
The surface must be clean, free of loose particles, release agents, dust, cement cream and other contaminants. When necessary, the surface must be previously moistened, but not saturated. On regularizing mortars a Primer should be applied.
HOW TO USE: Primer: 1 of STUHR CP ELASTIC WA-158 and 4 of water. Membrane: 1 STUHR CP ELASTIC WA-158 and 1 CP-II F or CP-II E. Polymeric Mortar: 4 STUHR CP ELASTIC WA-158 and 20 Type I Adhesive Mortar Regularization Mortar: 1 cement, 3 of washed average sand and 30% STUHR CP ELASTIC WA-158 on the weight of the cement. Use the structurant on corners, drains and bypasses when applying the second coat of the membrane. Consult the Waterproofing Project for the number of coats required and the locations that require the structure.
On smooth concrete surfaces, wash, brush or roughen the base to increase porosity and roughness. Do not use lime or gravel in mortars added with STUHR CP ELASTIC WA-158. Clean the tank after leakproofness testing before performing the potability test or using drinking water. Use the appropriate PPE for the preparation and application of adhesive and cement mortars (gloves, glasses and boots). Keep the application environment well ventilated. Accidentally hit body parts require immediate washing.
