Protectosil AQUA-TRETE 40
Protectosil AQUA-TRETE 40 is a clear, breathable, penetrating silane water repellent engineered for long-lasting concrete protection. This ready-to-use, low-VOC silane emulsion chemically bonds with silica within the substrate, creating a permanent hydrophobic layer that repels water and waterborne contaminants. By preventing ingress, it helps avoid damage from efflorescence, leaching, scaling, dirt buildup, corrosion of reinforcing steel, and freeze–thaw cycles. Designed to meet both national and state VOC regulations, it is particularly suitable for projects where solvent-borne products are restricted.

Common Applications
Ideal for protecting concrete, including GFRC, from acid rain, deicer scaling, and freeze–thaw damage. Reduces absorption of dirt and pollutants, prevents reinforcing steel corrosion, and resists alkalis, UV light, and waterborne chemicals. Suitable for infrastructure such as bridges, parking decks, marine structures, and architectural concrete where durability and aesthetics are essential.
