Although officially the East Surrey Tile Doctor we often get requests further afield through customer recommendations, this particular Terracotta Tiled floor was in Brixton, South London. You can see from the video below that the floor was not looking its best and had been splashed with paint.
Terracotta Tile Cleaning
To get the tiles clean we applied a strong dilution of Tile Doctor Pro-Clean mixed 50/50 with NanoTech Ultra Clean which combines well to produce a heavy duty alkaline cleaner/coatings stripper with a cleaner containing tiny nano sized abrasive particles that work deep into the floor. This combination is ideal for dealing difficult floors, its best to let it dwell on the floor for 10 to 20 minutes before working it into the tiles with a rotary machine fitted with a black scrubbing pad.
Once that was done the soiled solution was removed from the floor using a wet vacuum and we were then able to see a few spots where old wax remained on the floor. To deal with the wax Tile Doctor Remove and Go, which is a powerful coatings remover, was applied to the floor and left to dwell for a while before rinsing thoroughly with clean water and then treated with a steam cleaning machine to ensure the floor had been neutralised of all chemicals. It’s important not to leave a trace of chemical on the floor as they could react with the sealer.
The floor was still quite wet at this stage with small puddles of water forming in the dips of the uneven floor; the wet vacuum took care of most of this but the floor was still too damp for sealing so I left a couple of air blowers to assist with the drying of the floor and returned two days later to start the sealing.
Terracotta Tile Sealing
When we returned the floor was mainly dry but there were a couple of damp spots which I took care of with a heat gun. Tile Doctor Seal and Go was used to seal the floor; Terracotta can be very porous so eight coats were required to completely seal the floor so it was some time before it was finished.
When I finished I gave the customer instructions on how to maintain the floor. He was over the moon with the result and said that it had far exceeded his expectations.
Another happy customer.
