Right Stop Silane 40

Commercial Liquids


RIGHT STOP SILANE 40 is a breathable, colorless, non-staining, ready to use, deep penetrating concrete and masonry water repellent compound. It protects, stone, brick and block against the damaging effects of deicing chemicals, water intrusion, freeze-thaw exposure and airborne contaminants such as industrial fumes, smog and acid rain. RIGHT STOP SILANE 40 protects without altering the appearance or texture of the treated surfaces. RIGHT STOP SILANE 40 produces a non-filming water repellent surface while penetrating deep into the capillaries of the subsurface. Chemical reactions with the capillaries form long lasting water repellent groups that crosslink into a silicone compound.

RIGHT STOP SILANE 40 should be applied using airless spray equipment. A garden sprayer may be used for smaller projects only when an airless sprayer is not available. Do not use pressure pot or lacquer type paint sprayers. To product the proper material flow, reduce air pressure on pumping equipment and use spray tips with orifice sizes no smaller than 0.0l5” (0.9cm). Larger tips may be required with some spray equipment to get desired material flow. Flood the surface with RIGHT STOP SILANE 40 using a low pressure sprayer, roller or broom. Distribute material evenly. After the surface absorbs the RIGHT STOP SILANE 40, apply a second coat before the surface dries. Do not allow the material to puddle.
