Putting the shine back on Black Slate tiles

This black slate tiled floor installed in a hallway of a client's house in East Sussex had seen its share of foot traffic and as you can see from the photograph below the tiles had dulled and grout become stained.

Cleaning black slate floor tiles

We set about scrubbing the floor with a rotary machine fitted with a black scrubbing pad together with a dilution of Tile Doctor Pro-Clean which is an effective Tile and Grout cleaner especially recommend for stone floors due to its alkaline formula. It’s also quite good at stripping sealers from floors however this wasn’t too much of any issue in this case as most of the old sealer had been worn off. The next step was to get into the grout lines with stiff brushes to give the grout a good scrub, this step has to be done by hand as the scrubbing pads can struggle to reach the grout. The next step was to remove the soiled cleaning solution with a wet vacuum and wash the floor down with clean water to remove any remaining cleaning product and neutralise the floor before the next step of sealing.

Once the floor was dry we came back to seal it using two coats of Tile Doctor Seal and Go which put the shine back into the tile and will protect the tile and grout from stains going forward.
