Consider using travertine stone throughout your home, inside and out. For a formal look, polish the travertine smooth and ensure that all the pits are filled. For a more casual appearance or for exterior use, consider leaving the travertine in its natural state.

Select a sealer specifically made to be used on travertine, or on all types of stone. Any other type of sealer may create stains and will affect the durability of your travertine tile.

Clean the travertine tile with the cleanser recommended by the manufacturer of the sealer you chose. The chemicals in the two products should be formulated to work together and provide you with the best results.

Use a spray bottle and wet the entire surface of the travertine tile you plan to seal. Wait for the water to begin drying, typically after just a few minutes.

Rewet your travertine tile with the sealer. Make sure the entire surface of the travertine tile is covered with the sealer.

Wait 30 minutes and wipe away any excess sealer with a clean white cloth.

Remove an excessive buildup of sealer by rewetting the area with more sealer and wiping it away again with a clean white cloth.

Allow the newly sealed travertine tile to cure for 48 hours to get the strongest seal.
