These photos are of a four-year-old Limestone kitchen floor at a property in Boughton that the customer was finding hard to keep clean and maintain a shine. Part of the problem was he owned two dogs and we often warn about the problems of dog urine on sealed tile and stone due to it being high in nitrogen. On my initial visit I was able to ascertain that the sealer had almost completely worn off, leaving the stone vulnerable to dirt becoming ingrained into the pores of the stone. I come across this problem a lot, in my experience when stone floors are installed by tilers, they generally apply a single coat of sealant which wears off over time, and as discussed earlier can be prematurely degraded by strong chemicals. My quote to renovate the Limestone floor was accepted and included a deep clean to the stone and grout, stone polish and then re-seal. I arrived on site on the arranged date and began by scrubbing all the grout lines with Tile Doctor grout brushes and a 3:1 dilution of Tile Doctor Pro-Clean. I then moved on to a small handheld polishing machine to clean around the tile edges using 800 and 1500 grit diamond encrusted burnishing pad to achieve a deep clean. The process was then repeated throughout the rest of the area using larger 17” burnishing pads fitted to a floor polishing machine. The burnishing pads I used come in a set of four starting with 400-grit and moving up to 800, 1500 and 3000 grit, after each pad is applied the floor is rinsed with water and the soil extracted with a wet vacuum. It took me much of the day to complete this stage of the renovation and the floor was still damp so once done I left for the day, allowing the floor to dry off overnight. I returned the following day to complete the final polish using the 3000-grit burnishing pad, this gave a high polished finish which the customer had requested. This last pad is applied dry with only a little water splashed onto the tile, a process we call a spray burnish. The floor was then sealed with three applications of Tile Doctor Ultra Seal Sealant to protect the newly restored and polished tiles. Ultra-Seal is a penetrating sealer that soaks into those recently cleaned pores in the stone, occupying the space and preventing any dirt from becoming ingrained there. It’s also a natural look sealer so it doesn’t change the colour of the stone in anyway and is almost indetectable once applied. “Hard work from Philip has left us with a kitchen floor brought back to life – cleaned and sealed in little over 24 hours – brilliant job – Thanks” Before leaving I gave the customer some tips on maintenance and a complimentary bottle of Tile Doctor Stone Soap to enable him to keep the floor looking its best, this product works well with the sealant we applied and is PH neutral so won’t degrade the new sealer.
