The photographs below show a Terracotta Tiled floor we maintained that was installed in the kitchen and conservatory of a house in the Northamptonshire village of Holcot. The tile and grout was in good physical condition but had become ingrained with dirt and were now in need of a deep clean and reseal.
Cleaning Terracotta Tiles
First job was to protect the kitchen units, doors and skirting boards during the cleaning process for which I used blue plastic sheeting. Next a strong dilution of Tile Doctor Pro-Clean which is an industrial strength alkaline cleaning product that’s safe to use on tile and stone was applied to the floor using a mop. The solution was left it to dwell on the floor for twenty minutes in order for it to soak into the tile and get to work on the dirt. It was then worked into the floor using a rotary machine fitted with a black scrubbing pad and stiff hand brushes were along the grout lines where the pad struggled to reach.
The soiled solution was picked up using our large wet and dry vacuum and the floor was then rinsed with clean water to neutralise the tile and allow us to see which areas need further attention. The process was repeated until I was happy that any old sealer and all the dirt had been removed and then the floor was given a final rinse, wet vacuum and then left to dry overnight ready for sealing the next day.
Sealing Terracotta Tiles
When I returned the next day I checked the floor had dried using a damp meter which it was and so proceeded to seal the Terracotta tiles with seven coats of Tile Doctor Seal and Go which will protect the tiles from staining and also add a nice subtle shine to the floor. Terracotta is a clay based product and so naturally quite porous.
