Protectosil Chem-trete Pb100 Water Repellent 5 Gal Pail
A clear, penetrating, breathable water repellent for use on exterior above-grade concrete masonry units, brick masonry and most natural stones. Provides resistance against water, alkali attack, acid rain and waterborne staining. Penetrates into the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. It is especially suited for making porous substrates such as split-face block water repellent. By preventing water and waterborne contaminants from entering the substrate, it reduces problems such as efflorescence, leaching, acid rain deterioration, scaling, dirt buildup, staining, corrosion of reinforcing steel and mildew. It will not cause adverse surface appearance of the substrate. Treated surfaces are fully breathable because the natural moisture vapor transmission is not affected.
For use on materials such as concrete masonry units (split-face, fluted or ground-faced blocks) that can be protected from the ingress of wind-driven rain. Brick masonry, especially single wythe wall construction, can be treated to prevent moisture from entering and damaging interior walls. Other substrates that can be protected include sandstone, terra-cotta, Saint Joe brick, hand-molded bricks and most natural stones.
