DEFY Siloxane WB Concentrate is a blend of silanes and siloxanes designed to be diluted with water, at the job site. DEFY Siloxane WB Concentrate penetrates concrete and masonry up to 1/4" or more depending on surface porosity and moisture content at the time of application.

It reacts with the minerals in concrete and masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed by this process allow DEFY Siloxane WB Concentrate to become an integral part of the substrate and provide long term water repellent protection.

The coverage rates vary depending on the type of surface product is being applied to. 1 gallon of Siloxane WB Concentrate will make anywhere between 8-20 gallons, after it is diluted. Each diluted gallon has a coverage rate of between 75-150 sq. ft.
