A clear, penetrating, breathable water repellent for use on exterior above-grade concrete, brick masonry, concrete masonry units and some natural stones. Penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule. Protectosil® CHEM-TRETE® 40 VOC is not a coating and as a result will not discolor or change the surface appearance in anyway.
