The earthy hues of travertine flooring add beauty and style to your home, but this flooring may require occasional repairs since the calcareous, porous stone easily scratches. As a form of limestone, travertine naturally features small pits that formed when gas bubbles became trapped on the stone's surface. These holes, along with deep scratches and cracks, may require repair with travertine-coloured epoxy. Once you apply the epoxy and let it dry, your floor will look smooth and attractive again.
Clean the travertine you need to repair with floor cleaner. Remove any dirt or grit that fell into the cracks or holes requiring repair. Let the area dry thoroughly, or you can wipe it down with clean, dry rags to make the drying process go faster.
Apply the travertine-coloured epoxy to the cracks or holes with the putty knife. Once you fill the spot, scrape the putty knife across the newly-filled area at a 45-degree angle to make the epoxy even with the rest of the travertine.
Wipe the area with a damp rag or sponge to remove any extra epoxy. Continue to fill any leftover cracks or holes, then use the damp rag or sponge to remove the excess. Repeat this process until all holes and cracks get filled.
Dry the floor for at least 24 hours once you finish filling the last hole. Avoid walking on the newly-filled areas or cleaning the surface until the floor finishes drying.
Watch for holes that sink down with the new epoxy. Add more epoxy to these holes until you fill them and can smooth them down to match the same height of the surrounding travertine. You can buy travertine fill kits that contain mixing sticks and travertine-coloured epoxy.
The epoxy dries very quickly, so as soon as you apply it to an area, use the wet rag immediately to clean off the excess.
