I wanted to know what you think about the product Techniroc Aqua 3 in 1 for roofing. Is this really valid and on?
As far as I know, the TECHNIROC AQUA product acts as an anti-foam cleaner, it "mineralizes" the tile (which slows down its wear by abrasion) and ensures a water repellent treatment of the roof. It is a siloxane resin. It is therefore technically a satisfactory product.
I also know that the cost of this kind of treatment is quite high (to say the least in some applicators), which means that it is justified only in case of obvious porosity of the tiles. A treatment on healthy tiles is even discouraged (because it leads to the formation of a surface film).
