AquaMast polymer waterproofing under tiles — for bathrooms and WCs

Mastics and liquid membranes

AquaMast polymer waterproofing based on an aqueous polymer dispersion is applied under ceramic tiles in wet rooms — bathrooms, WCs, laundries and on balconies. The grey solvent-free paste goes onto concrete, brick, gypsum, plaster, gypsum plasterboard, gypsum fibre board and KVL board, is suitable for underfloor heating and is applied by brush, roller or spatula in at least 2 coats. Elongation at break is at least 250%, adhesion to concrete is at least 1.5 MPa, and the watertightness class of concrete with the coating is W8. Tiles are laid on cementitious adhesive not earlier than after 12 h; the material is not used in pools or water tanks.
