The pictures below are of a Riven Slate floor at a house in in the Leeds suburb of Horsforth which had been laid ten years prior. It’s probably difficult to appreciate from the images but the sealer on this floor was well worn through in the high traffic areas making it patchy in places. Without the protection of the sealer dirt was now ingrained in the pores of the stone leaving it looking dull. Riven slate is always tricky to clean thoroughly due to the rough surface and that combined with the ingrained dirt was making it very difficult to keep clean.
The floor now needed to be stripped of old sealer and then resealed and although I can provide a price for this over the phone my preference is to visit the property and survey the floor. In the case the owner had sent me some photographs via email however they were not too clear and so I felt it would be best if I paid the customer a visit to ensure I could give them an accurate price.

The floor was indeed overdue a clean and seal, as suspected dirt was ingrained into the areas where the seal had worn off. The house was home to a very busy family, so the area was subject to the significant traffic. I carried out a test clean on a small area and they were surprised by the results, when you live with a floor for so long you don’t notice the very slow decline in its appearance. They agreed to my quote and we arranged a time to return and carry the deep clean out.
Cleaning a Riven Slate Tiled Kitchen Floor
When I arrived, I started off by protecting the skirting and surrounding woodwork. Given the rough surface of the floor I first applied Tile Doctor Wax Away which is a very effective coatings remover that is designed for removing wax but works very well in these situations. The product was left to dwell for a round ten minutes so it could get to work breaking down the old sealer and then scrubbed in using a black scrubbing pad fitted to a rotary machine.
This process removed most of the dirt and old sealer, but some stubborn patches remained. To treat these, I replaced the black pad with a coarse 200-grit burnishing pad and finally some handheld diamond burnishing blocks for the edges and corners where more intricate work was required, and the circular pads struggle to reach.
I gave the floor a rinse, and extracted the soil with a wet vacuum, the floor was then left to dry off overnight.
Sealing a Riven Slate Tiled Floor
The next day I returned, first the slate floor was checked for moisture using the moisture meter. Once I was happy it was within the correct parameters, I then sealed with four coats of Tile Doctor Seal and Go. This is a modern water-based blend of acrylic polymers that provides both a stain resistant surface seal and a durable low-sheen finish also being water based there’s no smell as it dries.

The sealer really brought the stone to back to life and the lovely colours in the natural stones were now evident. The patchy appearance of the floor was gone, and the customer was happy.
I discussed with them how they should maintain the floor and advised them to use Tile Doctor Neutral Tile Cleaner. This is pH neutral cleaner that won’t prematurely erode the new sealer like the stronger products you find in Supermarkets which are only for use on Vinyl and Ceramic floors.
