STAIN-PROOF® Dense Stone Impregnating Sealer is an impregnating, invisible and breathable sealer that protects countertops from damage caused by water, salts and oil-based stains. Treated countertop surfaces become easier to clean, maintain, and keep looking good for longer. Dense Stone Impregnating Sealer provides lasting protection. Stain-Proof® sealers are formulated using a unique sealing technology – our sealer molecules are approximately 400+times smaller than other impregnators and penetrate much further into the pores to form a deeper water and oil repellent barrier, providing optimum protection to surfaces such as natural stone, bricks, pavers, tiles, engineering concrete and grout. Benefits Permanent premium oil and water repellence. 25-year written performance warranty when applied by a STAIN-PROOF Accredited Applicator. Three different custom sealing molecules for 3 levels of penetration and maximum stain repellence Includes a super penetrator for deep penetration of dense granites and marbles. Retains natural surface color and finish Super breathable: water vapor escapes freely preventing harmful moisture build-up inside the treated material Suitable for indoor, outdoor, residential and commercial use.
