MAPEI recommends using UltraCare Penetrating Plus Stone, Tile & Grout Sealer or UltraCare Penetrating Plus SB Stone & Porcelain Tile Sealer on all cement-based grouts, porous natural stone, clay tile, cement-based tile, quarry tile, brick and polished porcelain tile. UltraCare Penetrating Plus Stone, Tile & Grout Sealer leaves the surface unchanged in appearance, is breathable, and does not peel, flake or darken the tile or grout. Once fully cured, UltraCare Penetrating Plus SB Stone & Porcelain Tile Sealer helps protect against the absorption of both water and oil-based contaminants, making the surface easier to clean and maintain.
