Recently we were asked to resolve an unusual problem with Limescale deposits on Black Slate floor tiles installed in a WC at a house in Hove on the East Sussex coast. You can see from the photograph below how Limescale has left an unsightly white haze and water marks on the surface of the slate tile.
Cleaning Limescale from a Slate Tiled Floor
The first step was to remove the Limescale and any other sealer products from the floor using a strong dilution of Tile Doctor Pro-Clean scrubbed into the floor using a rotary machine fitted with a black pad, we also used a stiff brush along the grout lines and in those hard to reach areas around the toilet. The floor was then rinsed thoroughly with clean water and any stubborn areas revisited with a repeat of the same process until we were happy the tiles were clean. Had the Limescale proved harder to shift we would applied a stronger product such as Tile Doctor Grout Clean-Up which can remove mineral deposits.
Sealing Black Slate Floor Tiles
We left the floor to dry overnight and came back the next day to seal it using Tile Doctor Seal and Go, a highly recommended sealer for Slate which provides good stain protection with a low sheen finish, slate is quite porous and it took five coats before it was fully sealed.
I think you will agree the slate tiled floor looks transformed as well as being much easier to clean.

This Ceramic tiled shower cubicle was installed at house in Birmingham, although the Ceramic tiles were in reasonable condition the customer wanted the grout to be refreshed. Ten years ago it would have been necessary to scrape out the top layer of grout and replace however the modern grout colourant kits allow you to achieve the same effects for a lot less expense.
Cleaning Tile and Grout
The first job was to clean the grouting with a dilution of Tile Doctor Pro-Clean worked in by hand using a scrubbing brush, we also removed the towel radiator on one wall to make sure we could get to the grout behind. Pro-Clean is a very effective tile and grout cleaner that’s good at getting grease & grime out of the grouting, this process also provides a good foundation for the grout colourant which needs a clean surface. If you’re cleaning the grout yourself you may want to consider using Tile Doctor Oxy-Pro instead as it’s a similar product that is ready to use.
Once the grout was dry Grout Colourant in a Linen colour was applied into the grout lines and the excess wiped off, I then cleaned off all the excess Grout Colourant from the tile surface and gave the tiles a good clean. As you can see it made a big difference to the bathroom and I think you will agree the choice of Linen colourant worked well and blended in well with the colour of the tiles needless to say the customer was delighted.
I should mention that the Grout Colourant range supplied by Tile Doctor also seals the grout preventing it from staining and therefore ensuring it will look good for some time to come.
