What you'll need
- Stone sealer
- Grout float
- Color matched epoxy grout
- Damp sponge
- Paper towels
- Lint free cloth
- Soapy water
Step 1 - Grout
To start you need to find a colored epoxy grout that matches the color of your travertine tile floor. Ideally, you should take a small piece of tile to the tile or hardware store to be able to match the color exactly.
If that’s not possible, bring home plastic swatches of grout color, but be aware that the color you see on the swatch is a shade darker than the grout will be on the travertine tile floor.
Step 2 - Cleaning
Before you apply the grout, thoroughly clean out the hole. Do this with soapy water, then dry it with paper towels. Make sure you extract all the debris from the hole. Allow it to dry completely before proceeding.
Step 3 - Sealer
Use stone sealer on the travertine tile floor around the hole you need to fill. You’ll find that doing this will make it a great deal easier to clean up the grout later, once the hole is filled. Give the sealer a full hour to dry before you wipe the floor with a cloth. Make sure the cloth is lint free.
Step 4 - Filling
The important part is filling the hole properly. It needs to be well packed with the grout. Begin by mixing up the epoxy grout according to the instructions on the packet. Put a little of the grout on the hole and use the gout float to begin packing it into place.
Keep going until the hole has been filled. Be sure to pack the grout down firmly into the hole so it can bond fully. If you don’t, then the chances of the grout working its way out of the hole again are quite strong. Pack until no more will go in. Use a damp sponge to wipe the excess grout from the travertine tile floor. This where you’ll appreciate having put on the sealer first, as the excess grout will wipe up very easily. Don’t have to sponge too wet, and don’t wash the grout from the hole.
Step 5 - Cleanup
Give the grout a full 24 hours to dry before cleaning up. You might find that there’s a grout haze. If that happens, wipe the travertine tile floor with a dry paper towel to remove the haze from the stone. As long as you’ve put the grout in properly and wipe off the excess you should have a smooth finish on the stone. If there are other holes in the travertine tile floor, they can be repaired using the same method.
