Terracotta Tile Cleaning
To get the tiles cleaned 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 an cleaner containing tiny nano sized abrasive particles that work deep into the floor. This mixture is ideal for dealing difficult floors, its best to let it seep 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 dirty 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 seep in for a while before rinsing thoroughly with clean water and then treated with a steam cleaning machine to ensure the floor had been neutralized of all chemicals. It is 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 after two days to start the sealing.
Terracotta Tile Sealing
Once 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 spongy so eight coats were required to completely seal the floor so it was some time before it was finished.
When I was done, 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.
