ACTFLEX 400 Clear Waterproofing Membrane is a class 2 waterproofing membrane. It is transparent single-pack co-polymer emulsion combined with a synthetic
rubber latex emulsion. Engineered to function as a UV-resistant, transparent waterproofing barrier, this membrane is specifically designed to be applied over existing tiled
surfaces to create a waterproof barrier without necessitating the removal of the original tiles. ACTFLEX 400 is characterized by its toughness, durability, flexibility, and foot
traffic compatibility, all in a glossy transparent finish. This membrane is particularly suitable for areas where retaining the original substrate appearance is desired, such as
tiled shower areas, balcony decks, podium levels, and face brick walls. It is essential to perform compatibility testing before application.
