Protectosil® AQUA-TRETE 40

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.

Typical Applications

Protects concrete (including GFRC) from the damaging effects of acid rain, deicer scaling, freeze-thaw cycles, and freeze-thaw related damage. Keeps concrete clean by reducing the amount of dirt and other pollutants that may absorb into the substrate. Prevents corrosion on reinforcing steel from water, deicing salts, and other waterborne chemicals. Provides resistance against water, alkalis, acid rain, UV and staining.

Benefits at a glance

Protectosil® AQUA-TRETE® 40 is a silane in a proprietary emulsion system. Unlike other silane or siloxane emulsion systems, Protectosil® AQUA-TRETE® 40 is ready to use on concrete, without the need to blend oils, silicones, stearates or acrylates into the system. Protectosil® AQUA-TRETE® 40 is designed to provide a high level of surface beading with penetration to protect against wind-driven rain. The active components are unique because they chemically bond to the silica in the substrate and set up a hydrophobic layer of protection. By incorporating Protectosil® AQUA-TRETE® 40 into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEED) credits for both new and existing construction projects.
