Formed deep within hot springs, travertine stone has a naturally rustic appearance. Part of that appearance is due to the way that hot water vapor escaped the stone as it was forming. The vapor created bubbles in the forming stone that left behind numerous holes. Depending on how the travertine is cut into tiles, there may be dozens of holes in its surface. But those holes on a floor surface trap dirt, grease and food making it unsightly and even unhealthy after awhile.  Travertine tile is often sold in both filled and unfilled versions. Unfilled stones come with their holes still visible, You have the choice of leaving them alone or filling them on site. Remember that while they may add to the rustic charm of the tile, those holes are extremely difficult to get clean once they are soiled– even by a professional floor cleaner. To combat this problem, fill any holes you don't want to see in the stone with the same grout you use to install the tiles.  Tile and Grout Floor Cleaning in Boulder, CO 80301 can maintain all natural stone floors and grout for a stunning appearance.


1.        Saturate a foam paintbrush in an impregnating sealer meant for very porous stones like travertine. Wring out the brush slightly so it is not dripping. Carefully paint the sealer onto the surface of the travertine. Take care to avoid getting the sealer into the holes in the stone; just skim the top of the tile. The sealer will act as a grout release so the grout does not stick to the entire surface of the stone, but enters and fills the holes.

2.         Wait 10 minutes for the sealer to penetrate the travertine, then buff the surface of the floor with a lint-free cloth until the stone is dry and not tacky to the touch.

3.         Mix up sanded grout that matches the color of the travertine as closely as possible until it reaches the consistency of peanut butter

4.         Scoop up a small amount of grout onto the end of a grout float and  apply  it to the floor tiles.

5.         Work the grout into the holes on the surface of the travertine holding the float at a 45-degree angle to the stone. Scrape the float across the surface of the floor from several different directions to pack the grout into the holes in the stone. If you have not grouted the floor, work the grout between the tiles at the same time.

6.         Allow the grout to begin to cure for approximately 10 minutes. Saturate a grout sponge in water and wring it out well so it remains damp, but not dripping. Work it carefully over the floor, cleaning the excess grout from the surface of the stone. Use the corners of the sponge to shape the grout around the larger holes in the stone, as well as the grout joints. Rinse out the sponge frequently and continue wiping the stone until it is clean. Allow the grout to cure for a minimum of 24 hours.  And then, regular steam cleaning from Tile and Grout Floor Cleaning in Boulder, CO 80301 will make your floors shine and your home more beautiful.
