Water-Based, Penetrating Water Repellent for Concrete and Masonry

Prime Protect SWR is a ready-to-use, water-based siloxane/silane penetrating water repellent sealer. It soaks into the substrate and forms a water and chloride barrier that protects concrete and masonry from the damaging effects of water and salts, especially in freeze-thaw climates and marine environments. Prime Protect SWR is a breathable sealer that does not alter the appearance or texture of the substrate.
