Water-Based, Environmentally Friendly! DEFY MasonrySaver 20B is a V.O.C. compliant water repellent which contains an optimized 20% blend of silane and siloxane. This water based blend penetrates concrete pores up to ¼ inch or more depending on surface porosity and moisture content at the time of application. DEFY MasonrySaver 20B reacts with the minerals in the concrete in the presence of ultra-violet 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 in the process allow it to become an integral part of the substrate and provide long term water repellent protectionTechnical Available Sizes: 5, 30 & 55 Gallon Containers Coverage Rate: 40 - 80 sq. ft. per gallon, depending on surface porosity Application Temperatures: Minimum 40-90 °F Dry Time: 2-4 hours (allow 4 hours before rainfall) Application Method: Low-pressure Sprayer, or Airless Sprayer (use tip sizes between .011 and .015) Cleanup: Mineral Spirits
