HydroBloc impregnating agents keep mineral surfaces dry, clean and beautiful. Protected facades don´t get wet by driving rain, which prevents from efflorescence and frost damages as well. The next shower will wash dirt and dust away and keep the surface clean. The effectiveness of thermal insulation increases dramatically in dry conditions, so in the end surface protection lowers energy costs and safe money. ARCAN Impregnation materials protect concrete, mineral plaster, natural stones, brick and limestone.
