  • Mapei Mapegum WPS – Various Sizes



    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.


    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.

  • Protecta Waterproofer 3 Litres



    Protecta Waterproofer is a high viscosity cream-like impregnating fluid based on alkyl-alkoxy-silanes. When applied to cured Protecta® EX Mortar, the Waterproofer protects the surface by making it water repellent. The Waterproofer will also protect other porous substrates such as stone, brickwork and concrete in facades.

    Protecta Waterproofer also provides a comprehensive protection against efflorescence and decomposition caused by water-soluble pollutants, frost damage and attack by moulds and bacteria on damp substrates. The construction material’s physical properties, especially its water vapour permeability (Sd-value) is barely affected by application of Protecta Waterproofer.

    – Long-lasting and reliable
    – Simple, drip-free application with excellent workability
    – Water and VOC-free
    – High concentration of active ingredients
    – Alkaline stable
    – Does not build up a film
    – Extraordinary penetration depth
    – Can be applied without any loss, in one layer and without sag
    – Causes no discoloration or intensification of masonry surfaces
