Thompson's Waterseal Clear Voc Multisurface Waterproofing Sealer, 6-Gallon is an excellent clear waterproofing sealer designed for use on multiple surfaces when applied directly from the can. This sealer effectively eliminates chipping and spalling, providing long-lasting protection. It contains no silicones and is made up of several organic and inorganic solids carried beneath the surface by an aromatic solvent. These solids expand to literally cork up the pores of the treated material, preventing water damage on decks, fences, brick, patios, concrete driveways, and other exterior surfaces. Coverage varies depending on the porosity of the surface being treated, making it a versatile and reliable solution for protecting your outdoor spaces. Model Number:
