This Terracotta tiled floor was in the kitchen of a house in Didsbury near Manchester. The tiles had never been sealed before and so had become ingrained with dirt making them very difficult to clean.
Cleaning Terracotta Tiles
To get the Terracotta tiles clean I soaked tiles in a dilution of Tile Doctor Pro-Clean and left it to dwell for ten minutes. Then using a large 17inch black scrubbing pad fitted to a rotary machine and a stiff grout brush proceeded to work the cleaning solution into the tile and grout. This process soon turned the cleaning solution dark with the dirt that had been released from the tile and this was removed using a wet vacuum. The floor rinsed down with water and stubborn areas retreated, finally once happy with the condition of the floor the tiles were thoroughly rinsed to remove any trace of cleaning product prior to sealing and the floor left to dry overnight.
Sealing Terracotta Tiles
I returned the next day to seal the floor testing it first with a damp meter to make sure it had dried. I then started to seal the tiles using Tile Doctor Seal and Go which is a water based sealer so it doesn’t leave any smell as it dries. Terracotta is a very porous clay based material and so the floor took seven coats of sealer to do the job, this is not unusual and I’ve known some Terracotta to need even more coats of sealer.

This terracotta floor installed in a house in Denham, at the southern end of Buckinghamshire, had become discoloured with ingrained soil and a mix of old sealers and wax coating leaving an unsightly looking kitchen floor that was in need of stripping, deep cleaning and reseal.
Cleaning Terracotta Tile
I started the job using a solution of Tile Doctor Pro-Clean, which is a heavy duty alkaline product ideal for cleaning natural products such as Terracotta; this was scrubbed into the tiles quite aggressively with a black pad fitted to a rotary machine on slow speed. Once this had been completed we could see the remaining old sealers and wax layers and started to remove them using a strong tile stripper called Tile Doctor Remove and Go. Once we were satisfied we had removed all of the coatings we gave the floor a thorough rinse with clear water to remove any remaining residue and left it to dry overnight.
Sealing Terracotta Tile
The next day came back to do the sealing and checked the floor first for any spots we might had missed and also to ensure it had dried sufficiently. Tile Doctor Seal and Go was used to seal the floor, it’s a water based sealer so it doesn’t give off an odour when it’s drying and also offers durable stain protection together with a satin finish. Terracotta is very porous and in the end the floor actually took nine coats of sealer before it was fully sealed. Applying a sealer does takes a long time to apply as you have to wait for it to dry before applying the next coat.
The work took two days in all and you can see the difference for yourself, the floor is much cleaner and will be a lot easier to maintain going forward.
