Protectosil® AQUA-TRETE® 40 is a clear, breathable, penetrating water repellent intended for use on concrete. As a ready-to-use, low-VOC silane emulsion, this product reduces and prevents the ingress of water and waterborne contaminants by chemically bonding with silica, within a substrate, to form a permanent attachment of the water repellent. By preventing water and waterborne contaminants from entering the substrate, Protectosil® AQUA-TRETE® 40 reduces problems such as efflorescence, leaching, acid rain deterioration, scaling, dirt buildup, staining, alkali attack, corrosion of reinforcing steel and mildew. Treated surfaces continue to be fully breathable as 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 concrete. Protectosil® AQUA-TRETE® 40 water repellent is especially suited for application when solvent-borne products are not acceptable, as in states that have VOC regulations for AIM coatings. Protectosil® AQUA-TRETE® 40 meets most national and state VOC regulations.
