Description

H&C® HYDRO-DEFEND® SILANE SL-40 WATER REPELLENT is a high performance water repellent that penetrates into the substrate and provides long term weatherproofing protection. It’s a single component product that is ready to use and typically requires only one application. SL-40 will not darken the surface or leave a visible surface film. SL-40 penetrates deeper into the surface to chemically react with and bond to it.
