ProCover WB

Transparent water-borne impregnating agent.

ProCover WB is a transparent water-based impregnating agent (hydrophobic solvent) that creates a water-repellent surface. Alkali-resistant fluorocarbon resin combined with alkyl polysilane, that penetrates well into the substrate. Grease-repellent and diffusion-open - allows water vapour coming from inside the structure to pass through. Reduces salts moving to the surface of the structure. Does not form a superficial film. Reduces the growth of algae and green discolouration. Reduces the risk of frost damages.

Facades, floors in e.g. warehouses, roofs of fibre cement, concrete and clay, paving stones and other materials of mineral origin, such as sandstone, concrete, terrazzo, clay tiles, sand-lime bricks, paving and flagstones.

4 - 8 m²/l The practical spreading rate depends on application method, form and surface of the material.

Waterborne

Must be protected from frost. Should not be stored in temperature above +30°C.

The temperature must be between 5° C and 30° C and relative humidity <85 % RH.

Clean the surfaces from dirt, dust and salts. Clean the surface with Iso A-Clean according to instructions. The surface must be totally dry, clean and absorbing to ensure good penetration.

First coat:

Soak the surface with ProCover WB till saturation point by spraying “wet on wet”. ProCover WB must be applied in 1 – 2 “layers” in order to obtain the best result. Avoid application of the product in presence of strong wind or rain as this may cause stains or blotches. A surface already treated with a water-repellent product will not allow the penetration of other impregnating agents (hydrophobic solvents). Liquid not absorbed can cause stains on the surface – these are very difficult to remove. All splashes, if any, must be wiped away from windows immediately. It is recommended to cover windows before applying ProCover WB. Newly plastered or rendered walls must be fully hardened and dry before the application of ProCover WB. Always make a test coat to ensure the compatibility of product and surface.
