Surface water repellent. High quality water based product meant for weatherproof walls and roofs. Eco-friendly product, hazardless for the environment as well as users. Colorless, odorless, PRO WALL AQ does not change the initial aspect of treated surfaces. (no wet aspect, no brilliance or color change).

The protection is made of very thin active compounds which do not clog up the pores of substrates and allow the substrates treated to breathe without film-forming. The substrate remains permeable to vapor and air. Vapor and moist can evacuate from walls.

PRO WALL AQ will penetrate deeply into the substrate. It becomes waterproof, and is thus protected against weathering effects: moisture degradation, the frost and thaw cycle, rapid growth of moss and micro-organisms, dirt deposits…

High UV resistance product, PROWALL AQ is a Class A water repellent (> 95% efficiency) and remains efficient up to 10 years. Verified by ageing tests of the BBRI (Belgian Building Research Institute)

Water-repellent PRO WALL AQ


PRO WALL AQ has been designed for weather-proof porous mineral substrates. It is a high quality product (class A) which does not modify the initial aspect of treated surfaces. Once applied onto a surface, it is protected against water penetration. On the contrary, vapor and moist can evacuate the material thereby making it healthier.
It prevents water from stagnating in materials and bringing dust, dirt or plant spores with it. PROWALL Aq sanitizes materials as it enables them to dry and limits the development of micro-organisms.
