This job was a Terracotta Tiled kitchen floor in Paxford near Chipping Camden, the Terracotta tiles were in a large kitchen/diner which had a mix of different types of Terracotta due to the replacement of some damaged tiles. The recently fitted tiles were slightly darker than the older tiles in the kitchen area and the customer wanted a closer match but at the same time didn’t want the floor looking new (with all the wax and oil removed) just the old tiles made darker. You can clearly see the problem in the first photograph below.
Cleaning Terracotta Tiles
The floor had a heavy build of a wax and oil coatings which we tackled with a Tile Doctor Pro-Clean mixed with two parts NanoTech Ultra-Clean; this combines the strong cleaning power of the alkaline Pro-Clean with the nano sized abrasive particles in the Ultra-Clean to make a powerful cleaning agent. We left the solution to dwell and soak into the tiles for twenty minutes before working it in with a heavy floor buffing machine fitted with a black scrubbing pad, some areas had experienced little foot traffic and so had a thicker coating needed up to three cleans. All the edges were done by hand using wire wool pads and brushes. The soiled water was picked up by a wet and dry vacuum and then the floor was thoroughly rinsed with water using a high pressure spinning tool.
Terracotta Tile Sealing
We let the floor dry overnight and returned the next day to seal it for which we used a combination of Tile Doctor sealers. The first step was to darken some of the lighter tiles so they would match the others in the dining room we did this using a sealer called Colour Grow which brings out the colour in a Tile. Once we were happy with this floor was fully sealed using five coats of Tile Doctors new formula High Shine sealer to give a uniform look.
