Does porcelain tile need to be sealed?

Thumbtack Editors
Answered

No, porcelain tile often does not need to be sealed, especially if it’s glazed porcelain tiles.

However, if your porcelain tile is unglazed or a flat matte, you should seal it before you apply grout, using a surface sealant. This will add a high gloss to your porcelain tile. Most professionals also recommend using a penetrating sealant to seal the grout. A sealer can protect the grout against wear and damage. 

If you don’t have experience sealing porcelain tile, contact the best tile contractors near you and find out how much it will cost to have this done professionally.
