Refinish your marble tile floors for less than $100. This method also removes the thin layer of grout which has been left if grout was installed and not immediately cleaned afterwards.
Section your floor into smaller work areas. If you use small 5 x 5 ft sections it will make your work easier to keep clean. Use rolled up towels or drop cloths around the 5′ x 5′ perimeter to limit the amount of kickback spray from the spinning motion that the angle grinder generates. If you don’t do this, the milky colored spray will get everywhere.
Wet the section of the floor with water and cover the calacata tiles with a nice layer of water (more is better as it provides lubrication for the pad). Add a small amount of buffing compound and mix thoroughly (just spread it around with your hand). Be sure the water/compound mixture completely covers your work area. Make sure the water/compound mixture is milky and pretty dissolved before buffing. Be sure to wear gloves when doing this as the buffing compound is acidic and will dry up and irritate your skin.
Use the angle grinder with the nylon pad to go over your wood marble tiles one by one. Let the angle grinder do the work and just hold the sucker steady. It will take a bit of getting used to at first, but you’ll get the hang of it. Spend least 30 seconds on each tile to make sure the scrapes, scuffs, scratches are buffed down and smoothed as much as possible. Keep the grinder moving in small circles to polish the santana stone tiles evenly.
After you have finished the sectioned area, pour clean water over the area and mix it around making it wet again. Use a shop vac and suck it all up. Then if necessary, rinse with clean water and suck that up too. Move onto the next section until every tile is done.
