STAIN-PROOF® Waterbased Penetrating Sealer

Formerly Stain-Repella™, STAIN-PROOF Waterbased Penetrating Sealer provides penetrating stain protection while preserving the natural appearance and breathability of porous surfaces.

STAIN-PROOF® Waterbased Penetrating Sealer is an invisible, breathable sealer designed for natural stone, porous tile, concrete and masonry. The penetrating formula works beneath the surface rather than forming a topical coating, helping maintain the material's natural color, texture and finish.

According to the supplied product information, protection may last up to approximately five years depending on the surface, exposure, traffic and maintenance.
