Mapegum WPS is a liquid waterproofing membrane for interior surfaces. Not suitable for continual immersion in water or areas that are subject to rising damp.
Mapegum WPS is a ready-to-use, single component, solvent-free, grey coloured paste, with a base of synthetic resins in water dispersion. Mapegum WPS has a thixotropic consistency. This makes it easy to apply on all surfaces, especially those that are horizontal, sloping or vertical. After the quick evaporation of the water content, Mapegum WPS forms a flexible membrane which is non sticky, and strong enough to withstand light pedestrian traffic. It also creates an excellent surface that bonds perfectly to adhesives specifically used for laying ceramics, marble and natural stones.
CHARACTERISTICS
Mapegum WPS’s flexibility enables it to withstand normal expansion and contraction movements of the surface, due to variations in temperature and vibrations. Thanks to its flexibility, it acts as an anti-fracture membrane for substrates subject to light cracking.
Mapegum WPS is resistant to water, limewater (pH > 12), and water that contains chlorides, and normal household detergents and cleaning products.
Please be aware that this is a non stock item and lead times may vary.

Mapegum WPS can be used on all types of surfaces including gypsum, gypsum board walls, and cementitious renders. Light-weight concrete blocks, existing ceramic tiles, cementitious and anhydrite substrates, wood and wood substrates, magnesite and hot poured asphalt.
Great as a waterproofer for bathrooms, shower walls and floors before installation of ceramic tiles and natural ston. Waterproofing kitchen floors, walls and countertops before installation of ceramic tiles.
APPLICATION
Preparation of the substrate
Surfaces must be solid, clean and dry, and free of paintwork or any material that could compromise bonding. Thoroughly clean the surfaces to be waterproofed by washing and brushing them down.
Cementitious surfaces must be stable and dry, and not exposed to areas subject to rising damp. Substrates that are highly absorbent must be pre-treated with Primer G. Wait several hours until the coating is completely dry.
Application of the product
Mapegum WPS may be applied by trowel, roller, brush or spray. It must be applied evenly, in thin coats of approx. 1 mm each. Wait until the first coat is dry before re-applying. Drying time is roughly 1-2 hours.
The final thickness must never be less than 1 mm. Make sure there aren’t any gaps caused by surface imperfections.
After 12-24 hours from application of the final coat, the surface will be ready for laying ceramic tiles/natural stone, etc. Use an adhesive from the MAPEI range to lay these.
LIMITATIONS
• Do not apply if the temperature is lower than +5°C.
• Where necessary, create sloping surfaces to avoid the formation of puddles.
• Do not apply on damp cementitious surfaces, or on areas subject to rising damp.
• Do not apply on bitumen or asphalt membranes that could bleed oil/plasticisers.
• Do not use to cover cracks that are subject to shearing movements.
