Features & Benefits

Mapegum WPS is a ready-to-use, solvent-free, one-component, grey-coloured paste with a base of synthetic resins in water dispersion.

Mapegum WPS has a thixotropic consistency which makes it easy to apply on horizontal, sloping and vertical surfaces.

After rapid evaporation of the water content, Mapegum WPS forms a flexible membrane which is not sticky and which is strong enough to withstand light pedestrian traffic. It also forms an excellent surface which bonds perfectly to adhesives used for laying ceramics and natural stone.

The flexibility of Mapegum WPS enables it to withstand normal expansion and contraction movements of the substrate due to temperature variations and vibrations.

Mapegum WPS is resistant to water, limewater (pH > 12), water which contains chlorides and normal household detergents and cleaning products. Systems based on the use of Mapegum WPS flexible membrane, on which various types of tiles have been laid using MAPEI cementitious-based adhesives (such as Granirapid, Keraflex and Adesilex P9) and water dispersion adhesives (MapeGrip D2), have been certified for use in damp environments by the following institutes:

• Säurefliesner (Germany)
• Sp Swedish National Testing & Research Institute (Sweden)
• Norwegian Research and Building Institute (Norway)

• Mapegum WPS may be used on the following:
  • Plasterboard, gypsum or cementitious render
  • Suitable tilebacker board
  • Cementitious, anhydrite substrates
  • Existing ceramic and natural stone
• Suitable for waterproofing indoor floor and wall surfaces that are not subject to rising damp nor in permanent water immersion
• Flexible, anti-fracture membrane
• Apply before the installation of ceramic tiles or stone material
• Product certified EC1 Plus by the GEV Institute (Gemeinschaft Emissions-kontrollierte Verlegewerkstoffe e.V) as a product with very low emission of volatile organic compounds
• Ready to use
• Rapid application
• Floor coverings may be installed after 12 hours
• Excellent elongation properties
• No reinforcement required
• Some application examples
• Waterproofing walls and floors in bathrooms and shower cubicles before laying ceramic tiles, natural stone and mosaic
