A clear, penetrating, breathable water repellent for use on concrete, brick, concrete masonry units and some natural stones. Prevents water and waterborne contaminants from entering the substrate and causing premature deterioration. Penetrates into the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. Protectosil® CHEM-TRETE® PB VOC is especially suited for making porous substrates such as split-face block water repellent. This water repellent effect stands up against wind-driven rain.
