This penetrating, clear, thin primer is used to prepare porous, non-painted masonry and concrete for sealing with Topps Seal® and other coatings. ClearSeal™ absorbs and bonds light surface oxidation and forms an initial seal beneath the surface. Prepares oxidized or chalked surfaces so they may be coated over with excellent adhesion by a sealant like Topps Seal. ClearSeal™ applies at approximately one gallon per 100 – 150 sq. feet. The coverage will depend on usage.
