Travertine is limestone that has been formed in hot springs. Water movement causes the erosion of the stone, creating numerous holes of varying sizes. A polished travertine will have its holes filled with color-matched cement filler. Because the filler does not take a high polish, the polish can sometimes appear blotchy.
Pros: Diverse style options. Simple installation. Beauty.
Cons: Unsealed stone is reactive to acidic products. Holes can become larger over time and need filling as well as cleaning. Polished travertine is a soft floor, and will dull in traffic areas over time.
Cleaning tips: Vacuum regularly. Use neutral floor cleaners these will not leave streaks on floor and are gentle on the stone. Stay clear from generic stone cleaners, as they can be abrasive and etch the floors.
Periodic Cleaning: Turbo cleaning is the preferred cleaning method because it is the only process that removes soil from deep in pores. A quality penetrating sealer is advisable to help keep the stone from soaking up oils, water based stains and dirt. I would never put a clear coat finish on top of this material because it is difficult to remove and it then becomes a maintenance floor. Expensive!!!
