The photographs below were taken at a property in Weybridge where the owner had Limestone tiles installed throughout the Kitchen and adjacent dining room. Like any stone floor the sealer and appearance will degrade with use and in this case the tiles and especially the grout had become darker with ingrained dirt. The owners had decided it was time to the floor professionally cleaned and asked me to quote for the work.
Limestone is a beautiful stone that cleans up really well but to get the best out of it needs to be polished with burnishing pads using heavy equipment, something the tile shop salesman usually forgets to mention.
Having surveyed the floor I worked out a renovation plan which included tile and grout cleaning, stone polishing and finally sealing to protect it going forward. Happy with my quote we set a date for the work to begin.
Resealing a Polished Limestone Floor
My first job was to protect the kitchen cabinets from splashing with a sheet of decorator’s plastic about a foot from the ground upwards. I also like to apply a thin line of transparent mastic at the base of the cabinets where they meet the tile as this is usually a place where unwanted water can find its way in.
Once the kitchen woodwork was protected, I set about deep cleaning the grout. To do this I run a dilution of Tile Doctor Pro-Clean along the grout lines then leave it to dwell for five minutes and then scrubbed by hand using a wire brush until clean. All the waste is then rinsed off and extracted with a wet vacuum.
With the grout now clean and the soil removed I set up my rotary floor cleaning machine ready to burnish the stone tile and restore the finish with a set of diamond encrusted burnishing pads.
The first pad in the set to be applied is a coarse 400 grit pad that is designed to open the pores of the stone allowing dirt to be flushed out and removes existing sealers in the process. Water is used for lubrication and the during the following hours the process was repeated with the medium 800 grit and fine 1500 grit pads which gradually close the pores, buildup the polish and return the shine. This is a wet process which generates a slurry which is removed with after each pad with the wet vacuum.
Once the whole floor had been burnished it was given a final rinse and dried as much as possible with the wet vacuum. It was then left to fully dry off fully overnight.
Sealing Limestone Tiles
Returning the next day, I tested the floor was dry with a damp meter which confirmed the floor ready for sealing. The customer wanted a natural look to the floor so we chose to apply Tile Doctor Ultra-Seal which adds almost invisible protection. This sealer is an impregnator which soaks into the pores of the stone preventing dirt from becoming ingrained and keeping it on the surface where it can be easily removed. Two coats were applied and this should keep the floor protected for many years to come.
Once complete I advised the owner to stay off the floor for an hour or so and then they can return the furniture. For aftercare cleaning I recommend Tile Doctor Stone Soap which is a gentle but effective cleaner that will keep the floor clean whilst maintaining the patina and without harming the sealer.
