Type - Porcelain
Porcelain and Ceramic tile are very similar. Both are man made, Porcelain is considered to be a little higher quality. Tile consists of clay and a glaze coating. Clay is the body of the tile and the glaze is a coating that’s put on before a firing process.
During the firing process the clay cures and the glaze goes through a chemical reaction. The glaze becomes as hard as Granite. This tile is nonporous, etch and scratch resistant. Ceramic and Porcelain are non-porous and do not need to be sealed.
This tile is usually set with at least ¼ - ½ inch grout lines, which exposes a lot of grout. Grout is very, very porous and subject to staining. Clear penetrating sealers do nothing to seal grout.
The best and only recommended way to seal grout is to color seal grout with a Concrete stain that is the same color as the original grout. This is actually a coating for the grout which not only seals it off, but makes it look brand new and easier to clean.
