Travertine tile floors can offer advantages not found in other types of flooring, such as a more unique appearance and a more secure footing than you may find with ceramic tile. But in the installation of this tile you should be aware of common pitfalls you're likely to encounter if you're not aware of them.
Spreading Glue
In spreading the thinset glue that is typically used for adherence of this tile, avoid using any trowel except one with ½ inch teeth. Using any other trowel will result in applying too much glue that could ooze up from beneath the tile. Too little glue could inhibit the tile from adhering properly to the floor.
Choosing the Right Grout
When your tile has been glued to the floor and has dried, you'll need to use the proper grout to spread on it. A common mistake made in choosing grout is in assuming that there is a single, universal grout that should be used. Grout should be chosen according to the color that will match your tile, and the grout should be sanded.
Choosing the Right Sealer
Travertine tile, because it is porous, is easily stained by common household products that may be spilled on it. Choosing the wrong sealer will allow products such as coffee and wine to stain your tile, even after it is sealed.
