Pay close attention to any of the kit’s warning labels or notices. For example, it might advise you that certain types of tile, such as laminate, are not good candidates for refinishing. In this case, you may need to replace the tiles or talk with a professional installer. [4] X Research source

If the refinishing glaze that you are using is opaque, don’t worry too much about matching the replacement tile’s color exactly with the old ones. After all, they will all look the same after the paint coating. Repair small cracks or minor chips by applying a polyester putty to the area and then smoothing it out. This will make the tile waterproof once more and the repairs will be covered up by the refinishing process.

To remove a ceramic tile, drill into the center of the tile with an abrasive diamond drill bit. Work slowly, keeping your drill set to the lowest speed, and dip the drill bit in water frequently to prevent it from getting too hot.

This step can get pretty messy, so keep a vacuum close by to suck up the dust and debris. Use a mix of muriatic acid and water to loosen the grout. Only use the acid if you are working in a well-ventilated area and wear a mask and gloves while handling it. You’ll want to replace the grout either before painting or after the epoxy paint has cured. It is really your choice. Grout covered with epoxy paint will be uniform and easier to clean. But, some people like the look of grout lines.

For instance, try making a paste by mixing a little water with an oxygen bleach powder like OxiClean. Scrub the paste into the tile and grout with a stiff nylon scrub brush, let it sit for 10 minutes, then rinse or wipe it away completely with water.

If you are working with kitchen tiles, use a degreaser cleaner or rubbing alcohol to remove any oily residue. [10] X Research source

Remember that your goal is to remove any surface bumps and imperfections, not to sand it down to its base. Porcelain tiles need to be prepared with an etching liquid or a pumice block so the glaze will adhere to it. Sanding increases the lifespan of your refinishing job by allowing the epoxy paint to more fully adhered to the surface of your tiles. Don’t get too discouraged if you can’t see clear results from your sanding. Just keep going and rub your hands over the tile’s surface to feel the change in texture. [12] X Research source

If the day is warm or hot, opening the windows may shorten the drying time.

Check that the gloves that you plan on using fit you well. If your gloves are loose or baggy they may hurt your ability to apply the paint cleanly.

Some suggest using a sprayer to apply the primer, instead of rolling or brushing it on. This may prevent some stickiness, but you’ll likely want to practice with the sprayer beforehand, as they can sometimes be difficult to use. [17] X Research source

It’s generally best to use a foam roller, as it will leave less of a pattern on the tile. And, if you use a paint pan, make sure to change out the liner and refresh the paint before applying a second coat. Otherwise, you may end up with dried paint lumps on your tile. [19] X Research source

Tile reglazing fumes are strong and could cause sensitivity if you have allergies or asthma.
