HydroBloc Si 740 keeps mineral surfaces dry, clean and beautiful. The reactive silane connects with the building material and creates an inseparable connection. This together with the excellent wetting and penetration power and excellent hydrophobic properties results in super long-term durability.
The advantage compared to a liquid impregnation system is the easy and drip-free application. Besides the usual flat facade surface, the use at complicated structures and especially overhead is much easier in comparison to the application of liquid systems.
