Photographs below of a White Limestone tiled kitchen floor at a house in Wallingford that was proving difficult for the owner to clean effectively. I went around to inspect the floor and could see that the sealer had worn off leaving the tiles vulnerable to dirt becoming ingrained in the pores of the stone. Once this happens it makes the job of keeping the floor clean quite difficult as you really need to get the dirt out of the pores of the stone to do it right and of course once you do dirt will soon become trapped again without a sealer in place.
Given these Limestone tiles were White the dirt was more visible than usual, so the customer was keen to have the floor deep cleaned to remove the ingrained dirt and then sealed to prevent the problem reoccurring.

Cleaning White Limestone Kitchen Floor Tiles
To restore the floor back to its original condition I used a set of burnishing pads which are encrusted with industrial diamonds and come in different grades from coarse to very fine. Applied with a little water the coarse 400 grit pad is designed to strip the floor of dirt and old sealers whilst the remaining pads which are a finer restore the polished surface. Between each pad you need to rinse the floor with fresh water which is removed with a wet vacuum before finally being left to dry overnight.
On this occasion I found when I started with the 400 grit pad it wasn’t having the effect I was expecting and quickly established that this floor would need grinding back with a much coarser milling pad first. Fortunately I have numerous different types of pads available and was able to switch to a 50 grit milling pad which not only got rid of any remaining seal but also grinded out the ground in dirt. This does leave the stone in a rough condition so to restore the final finish I followed up with the 400 and 800 grit pads and finished with the 1500 grit pad, rinsing with water between each pad to remove the soil that is generated. It was quote a large floor, so it took two days to complete the process over every Limestone tile.
Sealing White Limestone Kitchen Floor Tiles
To seal the floor, I used Tile Doctor Ultra Seal which works by impregnates the stone occupying its pores and thus preventing dirt from becoming ingrained in there. This particular sealer doesn’t change the appearance of the stone and so leaves it with a natural look. Again, it was a large area, so it took two days to apply two coats. I then returned on day 5 to go over the whole floor with a 3000 grit polishing pad to give the floor a slight sheen.
