PENTREAT(TM) 244-100 water repellant penetrating sealer is a 100% active silane sealer that inhibits water and chloride ion penetration in concrete and masonry structures. A hydrophobic, impregnating sealer, it helps prevent chloride-induced corrosion of rebar, scaling, spalling, freeze-thaw damage and other causes of debilitating concrete. Designed for use on horizontal and vertical, new and existing concrete and masonry above-grade surfaces, it can be used on concrete parking structures, driveways, plazas, patios, walkways, median barriers, bridge decks and piers, ramps, traffic barring concrete, marine structures, vehicular repair and wash down facilities, and loading docks. Providing an effective chloride screen, it keeps treated surfaces cleaner and minimizes penetration from de-icing chemicals, salt and others that may damage concrete/masonry surfaces.
