Restoring the Appearance of Washed Out Black Slate Flooring with Tile Doctor Seal and Go Extra

This client from Charlwood near Gatwick had a couple of problems with his Black Slate tiled kitchen floor. First the washing machine had leaked something onto the tiles and second their son had a habit of scraping his toys across the floor. All of this had taken its toll on the original sealer and the Black Slate was now stained, scratched, and looking washed out.

The solution was clear in that both issues could be resolved by replacing the sealer which would take two days. Day one would would focus on removing all the original sealer by deep cleaning the tiles and then on day two a fresh sealer would be added to restore the Black colour of the Slate and protect the stone going forward. Having agreed my quote, a date was scheduled for the work to begin.

Charlwood is a small village in East Surrey on the border of West Sussex, it’s close to Gatwick airport with the perimeter running immediately to the Southwest. There were times when the local government wanted to move the village into West Sussex, but this was unpopular and so it stayed in Surrey.

Deep Cleaning a Black Slate Tiled Kitchen Floor

To remove the sealer, I applied a strong dilution of Tile Doctor Pro-Clean which is our go to tile and grout cleaning product that can also strip sealers off a floor. This was left to soak in for ten minutes before scrubbing it in with a Black pad fitted to a rotary floor buffer. I also gave the grout a good clean using more Tile Doctor Pro-Clean and a handheld scrubbing brush. Once done the soiling was rinsed away with more water and extracted with a wet vacuum.

I then turned my attention to the staining using a fine handheld diamond block. This gently skims a little stone away from the surface taking the stain and scratches along with it. A heat gun was used to speed dry the problem areas so I could quickly see if further work was needed and repeat the process until I was satisfied the Slate was looking at its best. After a final rinse the wet vacuum was used to remove as much moisture as possible and the floor left to dry off overnight.

Sealing Black Slate Kitchen Floor Tiles

The next day I returned and after passing the damp test I was able to seal the floor with Tile Doctor Seal and Go Extra. This leaves a nice sheen for clients who don’t want a very shiny floor but want good protection from the wear and tear caused by the kids.

Once complete the Black Slate looked like a new floor and client was very pleased with the result. Before leaving I took time to discuss on-going cleaning and recommend the use of a Neutral Tile Cleaner. This is important as many of the tile cleaning products you find in supermarkets are simply too strong for use on sealed tiles and can prematurely erode the sealer.
