What we do on a travertine restoration
Deep clean the stone and grout
Stone-safe chemistry that won't etch the surface, given time to break down old residue, then a scrub and extraction to pull the slurry out of the holes and grout lines instead of spreading it around. Grout that stays dark after that may need its own attention, covered on our grout cleaning page.
Strip old sealer that has gone cloudy
Topical sealers and floor finishes that were rolled onto travertine tend to yellow, scratch, and trap dirt. If a previous product is sitting on the surface, it comes off before anything else happens, or the new sealer won't reach the stone.
Fill open holes
Open voids get filled with a color-matched filler so they stop collecting dirt. This is the step that makes a cleaned floor stay clean. More on how that works on our hole filling page.
Hone out etching and wear
Diamond honing takes the surface down past etch marks, scratches, and worn traffic lanes to fresh stone. It also flattens the fill so it sits level with the tile. Honed travertine has a smooth matte look that most people expect from the stone.
Seal with a penetrating sealer
Once the stone is clean and dry, we use a penetrating sealer that soaks into the travertine instead of leaving a plastic film on top. It slows stains down. It doesn't make the stone stain-proof, and it doesn't stop acid from etching it.
