Do you have to seal Ceramic and Porcelain Tiles?

Ceramic and porcelain tiles that are glazed do not require sealing. But we do recommend that unglazed porcelain tiles be sealed, since they are more porous and susceptible to staining and water absorption.

It is also helpful to seal an unglazed porcelain tile before grouting to help in the clean-up process.
