Protectosil® 40H

Clear, penetrating, breathable water repellent for use on above-grade concrete.

PRODUCT OVERVIEW:

Protectosil® 40 H is a clear, penetrating, breathable water repellent for use on all types of exterior above-grade concrete. This product penetrates the surface to chemically bond to the substrate, resulting in a permanent attachment of the water repellent molecule. Protectosil® 40 H is not a coating and as a result it will not leave a film or gloss on the surface.

APPLICATIONS:

For use on concrete, to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and other waterborne chemicals. For use on highways, airport runways and concrete pavement, to reduce scaling due to deicer chemicals. Reduces the expansion of alkali-silica reactivity. Reduces the effects of mildew, efflorescence and stains on vertical concrete surfaces. Imparts water repellency to a substrate for an extended time
