Protectosil® CHEM-TRETE® PB 100

FOR BRICK, CONCRETE AND CONCRETE MASONRY BUILDINGS

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. Protectosil® CHEM-TRETE® PB 100 is especially suited for making porous substrates such as split-face block water repellent. This water repellent effect stands up against wind-driven rain.

By preventing water and water-borne contaminants from entering the substrate, Protectosil® CHEM-TRETE® PB 100 reduces problems caused by efflorescence, leaching, acid rain deterioration, scaling, dirt build-up, staining, corrosion of reinforcing steel and mildew. Protectosil® CHEM-TRETE® PB 100 will not cause adverse surface appearance of the substrate. Treated surfaces are fully breathable because the natural moisture vapor transmission is not affected. This will eliminate problems caused by entrapped moisture, including blushing of the sealer and freeze-thaw damage to the masonry.
