Step 1 – Clean the Tile
Whether you want to paint natural stone tile that is indoors or out, you first have to make sure that is clean. Sweep the tiles with a broom and pick up all the dust. Use a vacuum cleaner if you really want to make sure you get all the dust off the tiles. Then you need to wash the tiles. If you intend to paint natural stone tile that is outside, the easiest way to clean it is to use a pressure washer. The tile must be clean so that no dust or dirt will remain and show through the paint when it is dry.
For inside cleaning, remove all the furniture from the room so that there won’t be anything in your way. You do need to use special cleaners for the stone tile, but you already know this if you have had stone floors for a while. Mop the floor with the cleaner and let it dry.
Step 2 – Seal the Stone
Before you start painting the natural stone you do have to apply a sealant. You can purchase this sealant at home improvement or flooring stores. Shake the can vigorously before you open it, even though it has probably been well shaken at the floor. Open the can and pour out some of it into the paint tray. Attach a broom handle to the paint roller to make the work easier on your back. Paint the floor with the sealant in the same way as you would paint a wall. Then you must let the sealant dry thoroughly, which could take a few hours.
Step 3 – Inspect the Look of the Natural Stone
As the sealant is drying on the floor, inspect it very carefully to make sure that you have covered all areas and that there are no spaces that look duller than the others. If everything is to your satisfaction, all you have to do is sit back and wait. Allow at least 24 hours for the sealant to dry completely before you walk on the tiles or move any furniture back into the room. If you do notice any imperfections, you may have to repeat the process.
