We were asked to look a bathroom at a flat in Kensington by a property management company; the slate tiled floor was textured with lines and the stone was affected by a number of problems including limescale and grout haze which had been partly sealed in. The owner was at the property when I arrived and I was able to demonstrate how it was possible to remove the limescale and grout haze using Tile Doctor Grout Clean-up which is an acid based product and so was given instructions to complete the job.
Removing Limescale from Textured Slate
Armed with more quantities of Grout Clean-Up we were able to remove the limescale from the surface of the slate tile. The floor was then rinsed and then covered with Tile Doctor Remove and Go in order to remove the remaining sealer. We had to repeat this process twice in order to remove the grout haze that had been locked in under the sealer.
Sealing Textured Slate
After a thorough rinsing down to ensure no products remained on the floor we left it to dry and returned later to apply three coats of Tile Doctor Colour Grow which will provide future protection and as you can see from the photographs really helped to give the floors appearance..
I then explained how to clean the tiles going forward. She was extremely happy with the work carried out and also pleased with the management company for contacting us in the first place.
