Protectosil Chem-Trete PB

Protectosil Chem-trete PB VOC is a clear, penetrating, breathable water repellent for use on concrete, brick, concrete masonry units and some natural stones. It 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. Treated surfaces are fully breathable because the natural moisture vapor transmission is not affected.
