How to Renovate Dirty Terracotta Tiling

We were contacted by the owner of a property in Moulton with a problematic Terracotta tiled kitchen floor. She was seriously considering ripping up the entire area of tiling and replacing it as she was having a new kitchen installed. Both her and her husband were concerned that unless I could restore this floor to somewhere near to its original condition, they would need to replace it.


I went over to inspect the Terracotta tiles and could see the entire surface was deeply ingrained with soiling and the grout lines were filthy. After carrying out a test it became obvious that the previous sealer had been applied very sparingly and had mostly worn away, leaving the stone prone to staining. Terracotta is a very porous tile and dirt had become ingrained in the pores leaving it looking very dull and difficult to clean.


I completed the test on a small part of the floor and the customer could see the results which could be achieved. Happy with the result they agreed my quote and we set a date for my return to complete the floor.

Cleaning a Terracotta Tiled Kitchen Floor

The tiles turned out to be made of a fairly soft Terracotta which meant that we were able to deep clean them extremely effectively using a strong dilution of Tile Doctor Pro-Clean. We used Tile Doctor Remove and Go in particularly stubborn areas.

The process I use is to spray the Pro-Clean onto the floor and leave it to soak in for about ten minutes before being worked in using a heavy rotary machine fitted with a black scrubbing pad. The resulting slurry is removed using a wet pick up vacuum. All the dirt and virtually all of the old sealer was removed at this stage; the remaining patches around the edges of the area being finished by hand with a 200-grit burnishing block. The grout lines were then cleaned by hand with an angled grout brush.


Finally, the deep-seated oil stains in front of the cooker were brought out using Tile Doctor Oxy-Gel which was left to dwell on the marks for an hour before being agitated with a diamond burnishing pad and rinsed away with a wet pick up machine. The floor was rinsed with water and allowed to dry off overnight.

Sealing a Terracotta Tiled Kitchen Floor

The following day I inspected the floor and checked it was ready to be sealed. All was well so I applied an initial coat of Tile Doctor Colour Grow which is an impregnating sealer that occupies the pores in the tile enhancing the natural colours of the Terracotta and provide a base layer of protection from staining.


I returned at a convenient time once the kitchen was completely installed to finish the job. This involves carrying out a light maintenance clean with Tile Doctor Neutral Cleaner and once the floor was dry, I applied 5 further coats of Tile Doctor Seal and Go which provides a pleasing satin finish which is really suited to this type of floor.


The customer was very happy with the results and has left the following feedback. "We were really pleased with the results, thank you!"
