The type of stone, tile and grout that you have will determine if sealing is necessary. Glazed ceramic and porcelain tiles have almost no porosity and are highly resistant to staining; therefore, sealing is not required. However, it is beneficial to seal unglazed, polished porcelain floor tile. If either the tile or grout is considered porous, such as natural-stone tile, terra cotta, Saltillo, brick or cement-based grout, sealing is recommended.
MAPEI recommends using UltraCare Penetrating SB Stone, Tile & Grout Sealer on all cement-based grouts, porous natural stone, clay tile, cement-based tile, quarry tile, brick and polished porcelain tile. This sealer leaves the surface unchanged in appearance, is breathable, and doesn’t peel, flake or darken the tile or grout. Once fully cured, it helps protect against the absorption of both water and oil-based contaminants, making the surface easier to clean and maintain.
It used to be said that solvent-based products were more durable and longer lasting than water-based products. In today’s world, we have water-based technology that is equal to, or better than, solvent-based products. Because of its unique molecular construction, UltraCare Penetrating SB Stone, Tile & Grout Sealer is formulated for use on both porous and dense surfaces.
