Details below of a Sandstone floor installed in the Kitchen of a house in Clapham, South London. The client had not been happy with the floor since it had been installed because the tiler hadn’t applied the seal correctly. The owner had also had a quote from a stonemason who had recommended grinding off the top later of stone. I explained that that would not be necessary and went on to explain the process to restore it. As it turns out my quote was £500 cheaper that the Stone mason but I was confident I could get as good a result and the customer could see I knew what I was talking about and gave the job to me.
Sandstone Tile Cleaning
I began work on the floor using a coarse diamond burnishing pad fitted to a rotary scrubbing machine with a little water. I slowly scrubbed the floor in small areas and removed the old sealer from the whole tile. The next step was to tackle the grout which was done by applying Tile Doctor Pro-Clean worked in along the grout lines using a stiff grout cleaning brush. After this the pad was replaced on the rotary machine with a medium brush head and the floor was given a good scrub followed by rinsing thoroughly with fresh water.
At this stage it was evident that a couple of stubborn areas were still in need of attention due to the old sealer still being present so Tile Doctor Remove and Go was applied which is a strong sealer stripper and left to dwell for around 40 minutes before being scrubbed in and washed down again.
I can recommend a Wet Vacuum at this point as they are great at removing liquids from floors; at this point I left for the day to allow the floor to dry overnight ready for sealing the next day.
Sandstone Tile Sealing
Then next day when I returned I checked to make sure the floor was dry and ready to seal, there were a couple of little patches I needed to redo and once they were rinsed I dried them using my heat gun. I then sealed the floor with four coats of Tile Doctor Colour Grow and when the last coat had dried I demonstrated to the customer that it was fully sealed using a water test.
The client was really pleased with the results and that I had saved him so much money and left the following comment on our feedback system.
“Bill was great and worked hard to restore and protect the floor. We’re very pleased. There has been some accidental damage outside which I’m happy we’ll sort.
