Protectosil® AQUA-TRETE® EM is a penetrating, waterborne, vapor-permeable water repellent for use on concrete, brick, concrete masonry units and some natural stones. As a ready-to-use, low-VOC, silane/siloxane emulsion, this product reduces the ingress of water and waterborne contaminants by chemically bonding with siliceous materials within a substrate to form a permanent attachment to the water repellent molecule. This can prevent premature deterioration among other things. By reducing the ingress of water and waterborne contaminants into the substrate, Protectosil® AQUA-TRETE® EM reduces such problems 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. Protectosil® AQUA-TRETE® EM water repellent is especially suited for applications where solvent-borne products are not acceptable, such as states that have VOC regulations for AIM coatings. Protectosil® AQUA-TRETE® EM is VOC compliant in all 50 states, including California’s SCAQMD.
