This Terracotta Tiled floor was located in a house in the town of Ringmer, East Sussex, it had been a while since it had last been thoroughly cleaned and re-sealed and was now well overdue for some extra attention.
Terracotta Tile Cleaning
To get the tiles clean we applied a strong dilution of Tile Doctor Pro-Clean which is a heavy duty alkaline cleaner/coatings stripper ideal for tiled surfaces. We let the solution 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. The photograph below shows the floor half way through this process with the top section cleaned and the bottom section still to do.
The soiled solution was removed from the floor using a wet vacuum and any stubborn areas re-treated before thoroughly rinsing the tiles down with clean water to remove any remaining product and neutralise the floor prior to sealing.
Terracotta Tile Sealing
Once the floor was dry the floor was sealed with TIle Doctor Seal and Go which took some time to do as you need to wait until the first coat dries before applying the second. Terracotta is very porous so seven coats were required to completely seal the floor.
I thing you would agree from the photographs the floor is much improved and the sealer should keep the Terracotta tiles looking good and much easier to keep clean going forward.
