Water Seal

Cementone Waterseal is a long lasting, deeply penetrating, water repellent solution for porous external walls and fascias. It deposits a waterproof resin in the capillaries of the substrate which expands on reaction with residual moisture and almost completely reduces rainwater penetration, whilst still allowing the substrate to breathe. This reduction of the movement of water through the structure improves insulation, reduces dirt retention, mould and algae growth. It also reduces the incidence of efflorescence. Cementone Waterseal is completely colourless although it may enhance the colour of treated surfaces in rare cases. Before using this product refer to the relevant Health & Safety Sheet.
