Description
our solution for waterproofing walls and floors in bathrooms and shower cubicles before laying ceramic tiles, natural stone and mosaic. we apply a ready-to-use, solvent-free, one-component, grey-coloured paste with a base of synthetic resins in water dispersion. the solution has a thixotropic consistency which makes it easy to apply on horizontal, sloping and vertical surfaces. After rapid evaporation of the water content, it 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 the solution enables it to withstand normal expansion and contraction movements of the substrate due to temperature variations and vibrations, it acts as an anti-fracture membrane for substrates which are subject to light cracking (< 1 mm).
The solution 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 (Ultramastic III), have been certified for use in damp environments by the following institutes:
