Technical Characteristics

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, marble 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 Keraflex and Granirapid and water dispersion adhesives (Ultramastic III), have been certified for use in damp environments by the following institutes:

• – BRANZ appraisal with testing to AS/NZS 4858:2004 (Australia and New Zealand).

• – Säurefliesner (Germany);
