Protectosil® CHEM-TRETE® 40D

Protectosil® CHEM-TRETE® 40D

Clear, penetrating reactive sealer and surface consolidant.

PRODUCT OVERVIEW:

Protectosil® CHEM-TRETE® 40 D is a clear, penetrating, breathable water repellent and consolidant for use on exterior above-grade calcareous stone such as limestone and marble, brick masonry and natural stone. This product penetrates the surface to chemically body to the substrate, resulting in a permanent attachment of the water repellent molecule. Protectosil® CHEM-TRETE® 40 D is not a coating and as a result will not change the surface appearance of the substrate.

APPLICATIONS:

Makes limestone and marble water repellent, and acts as a surface consolidant. For use on brick masonry, to protect against the ingress of wind-driven rain and to harden soft bricks. For use on concrete that has a high percentage of limestone or coral aggregate, to consolidate and make water repellent. Reduces the damage that salt burst has on natural stone, and the effects of mildew, efflorescence and stains on vertical concrete and masonry buildings.
