Mapei Mapegum WPS Fast Tanking Membrane

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:
