Stripping Layers of Sealer from Slate Tile

I was asked to strip and re-seal these interesting Chinese Slate tiles that were installed in the kitchen floor of a property in Hale Barns, Cheshire. It seems the tiles had been re-sealed over the years without giving them a deep clean first resulting in dirt and grime being sealed in between layers of old sealer making them impossible for the customer to clean.

Cleaning Chinese Slate Floor Tiles

To remove the many layers of sealer and get the tiles clean I let them soak in a strong dilution of Tile Doctor Remove and Go which is a coatings remover for the stripping of sealers from floors that is safe to use on Tile, Stone and Grout. This was worked into the tile and grout using stiff brushes followed by steam cleaning the floor. The resulting soiled solution was removed and the floor washed down with clean water to reveal the bare stone; stubborn areas were re-treated using the same process before leaving the floor to dry before sealing.

Once I was satisfied the floor was dry it was sealed using Tile Doctor Seal and Go which is a highly recommended sealer for slate that leaves an attractive low sheen finish and smooth surface, it’s also a water based sealer so there is no smell.
