Thompson's Waterseal Clear Multisurface Waterproofer Sealer Spray, 12 oz. is an excellent clear waterproofing sealer designed for use directly from the can on a variety of surfaces. It effectively eliminates chipping and spalling by penetrating beneath the surface with a unique blend of organic and inorganic solids carried by an aromatic solvent. These solids expand to cork up the pores of the treated material, providing superior protection against water damage. I for decks, fences, brick, patios, concrete driveways, and other exterior surfaces, this water-based formula contains no silicones and covers approximately 60 square feet per can, depending on surface porosity. Its versatility and reliable performance make it a choice for both interior and exterior wood, brick, and concrete applications. Model Number: TH.010100-18
