The Advantages of a Film-Forming Coating and Silane/Siloxane Water Repellent DEFY Split Face Block Water Repellent is a waterborne block sealer that causes water to shed, and significantly reduces water penetration into a wall system. It is specifically designed for lightweight, split face and fluted block. This product is a silane/siloxane blend with acrylic elastomers that penetrate small pores and reduces the size of larger ones. This combination gives DEFY Split Face Block Water Repellent the advantages of both a film forming coating and a hydrophobic silane/siloxane water repellent.Technical Available Sizes:1 & 5 gallon Recyclable Containers Coverage Rate:Sq.

As a result, the special siloxanes in DEFY Solvent Base Water Repellent react to form strong chemical bonds beneath a treated surface. These bonds allow the product to become a physical part of the structure and provide long-lasting water repellent protection without altering the surface appearance. 100% Breathable ProtectionMoisture, from either internal or external sources, is usually present in masonry and concrete. Film-forming sealers and silicone coatings form a water resistant surface that traps water vapors inside. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration and freeze-thaw damage. DEFY Solvent Base Water Repellent is 100% vapor permeable, a non film-forming water repellent that penetrates and lines masonry and concrete pores.Ideal for previously treated surfacesWith its mineral spirits base, DEFY Solvent Base Water Repellent is an ideal maintenance product for previously treated surfaces as the mineral spirits carrier will allow the product to bond with surfaces that have previously been waterproofed. It can also be applied over siliconized acrylic concrete stains. Product UsesDEFY Solvent Base Water Repellent is an extremely versatile product that can be used on most vertical or horizontal exterior, above-grade masonry surfaces including: Adobe Architectural Concrete - precast or cast in place clay brick mortars natural stone limestone granite sandstone terra cotta exposed aggregate products Portland cement stuccos concrete driveways, sidewalks, patios (New masonry should be cured for a period of not less than 14 days.)
