Facade Waterproof (WP7-401) is an invisible exterior wall protector and sealer from the Tec7's Waterprotect series. WP7-401 helps prevent frost damage and prevents the loss of heat through the walls, rain penetration, green deposits and moss growth on north-facing facades. In addition, WP7-401 reduces the adhesion of dirt, making facades easier to clean.

Tec7 Facade Waterproof is easy to use and is visible when applied, but invisible after penetration. In addition, this product is applicable on all porous, mineral substrates and is fully absorbed after 30 to 60 minutes. This product contains no solvents nor VOCs.
