These grubby looking Textured Ceramic Tiles were in a bathroom of a house in the old village of Narborough near Leicester. As you can see from the picture below they were overdue for a deep clean and the customer has been struggling to do that. On inspection it was clear that the textured surface which was designed to prevent slipping has become ingrained with dirt making them difficult to clean and therefore lose appearance. This can be a problem with a rough surface and so to prevent dirt building up the surface is sealed, however sealers do wear off after a few years depending on use and I suspect this is what happened here.
Cleaning and Preparing Porcelain Tile and Grout
To remove any remaining sealer from the less worn areas and clean the tile and grout a strong dilution of Tile Doctor Pro-Clean was applied and left to soak in to the surface for around ten minutes before scrubbing it into the tile with a rotary machine fitted with a black scrubbing pad and also a stiff hand brush along the grout lines. The floor was then rinsed down with fresh water which was removed with a wet Vacuum. This stripping and cleaning process was repeated until the tile and the grout was looking new again after which the floor was given a thorough rinse in order to remove any trace of product and then dried as much as possible using the wet vacuum.
Sealing Micro Porous Porcelain
We left the floor to dry and then came back two days later to seal the floor, testing it first with a damp meter to ensure it was dry. The two days was enough time to dry it out so we moved on to seal the floor using two coats of Tile Doctor Colour Grow which is an impregnating sealer that occupies the pores in the tile providing strong stain protection as well as lifting the colour.
