Thompson's WaterSeal Clear Water-Based MultiSurface Waterproofer Sealer, 12 Oz.

An excellent clear waterproofing sealer when applied directly from can to multi-surfaces. Eliminates chipping and spalling. Contains no silicones, consists of several organic and inorganic solids that are carried beneath the surface by an aromatic solvent. Solids expand and literally cork-up pores of material being treated. Prevents water damage on decks, fences, brick, patios, concrete driveways, and other exterior surfaces. Covers approximately 60 sq. ft. per can depending on porosity.
