Water repellents, stones

The product reduces the ingress of water and water-borne contaminants into the substrate and thereby prevents premature deterioration. It penetrates the substrate and chemically bonds with silica to form a permanent attachment of water repellent molecules. Protectosil® AQUA-TRETE® EM water repellent is especially suited for applications where solvent-borne products are not acceptable, such as in states that have VOC regulations for AIM coatings. Protectosil® AQUA-TRETE® EM is VOC compliant in all 50 states, including California's SCAQMD.

By reducing the ingress of water and water-borne contaminants into the substrate, Protectosil® AQUA-TRETE® EM reduces various problems such as efflorescence, leaching, acid rain deterioration, scaling, dirt buildup, staining, corrosion of reinforcing steel and mildew. Treated surfaces are fully breathable because their natural moisture-vapor transmission is not affected. This will reduce problems that entrapped moisture can cause, including blushing of the sealer and freeze-thaw damage to the masonry.
