We were asked to come and advise a customer regarding their stone floor which the customer was struggling to keep clean. The property was in High Bentham which lies on the River Wenning, just West of the Yorkshire Dales National Park.


Cleaning a Black Riven Slate Tiled Floor
To get the tiles clean we burnished the stone floor with a coarse 200-Grit Diamond pad fitted to a weighted buffing machine using water for lubrication. The floor was then rinsed and then the process repeated using a series of different graded pads, namely the 400 and 800 grit burnishing pads which further cleaned and resurface the appearance of the stone.
The grout was cleaned using Tile Doctor Pro-Clean which was scrubbed into the grout lines by hand; Pro-Clean is a heavy-duty cleaner which gets to the really stubborn stains and it did a great job at getting the grout looking like it should. The cleaning process was then finished off by rinsing the floor with water and extracted the slurry with a wet vacuum. The floor was inspected and retreated to the same process where more work was required. We usually find leaving Pro-Clean on a stain for longer and assisting with a bit of steam helps to lift the dirt out of the pores of the stone.
Once cleaned thoroughly we rinsed the floor again and then extracted as much moisture from the floor as possible with a wet vacuum before leaving it to dry off fully overnight.
Sealing a Riven Black Slate Tiled Floor
We called back the following day to apply a sealer first checking the floor was dry using a moisture meter. All was well, so we started to apply the first of two coats of Tile Doctor Colour Grow, a third coat was attempted but the slate would not accept any more sealer, and this was removed with a cloth. It is important to know if you have reached FCS (Full Cure Sealability) if not then the pores of the tiles will still be open to accepting dirt and the job won’t last long. Over a very short period of time the tiles will diminish in stature and finish.

The floor looked lovely when finished and the customer was very happy with the overall result.
