Photograph below of a very dirty Limestone tiled kitchen floor at a house in Henley on Thames, the sealer had worn off some time ago and now the tile was trapping dirt that was proving very difficult for the home owner to remove. I do love floors in this condition as they make great adverts for how well Tile Doctors can restore your floors.
Cleaning Limestone 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 four different grades from coarse to very fine. Applied with a little water the coarse pad strips the floor of dirt and old sealer 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.
Sealing Limestone Floor Tiles
The next day I check the floor was dry which it was and then proceeded to seal the Limestone with two coats of Tile Doctor Colour Grow which is a colour enhancing impregnating sealer which occupies the pores in the natural stone to provide maximum stain protection.

Kitchen floors can be very high traffic areas which means the sealer will wear off quicker, for these areas you should consider maintaining the floor on a regular basis and if necessary applying more sealer.
