Tile, Stone & Grout Sealer penetrates the surface pores to form a barrier against moisture and stains while fully allowing vapor transmission. Tile, Stone & Grout Sealer is an economical, entry-level alternative to impregnating/penetrating sealers. It is not a surface coating and will not change the natural look. All treated surfaces become harder and less slippery. Can be used on interior and exterior surfaces.
