While fantastic to look at, Riven Slate tiles can be particularly difficult to keep clean. The natural unevenness of the stone causes dirt to become more easily trapped and more difficult to remove. Over time, heavy buildup of ingrained dirt can have the effect of dulling the colours in the stone. This was the case with this large area of Riven Slate tiles at a very busy farmhouse in the Lincolnshire port town of Boston, the original namesake for the perhaps more famous city in Massachusetts, USA.
Cleaning Dirty and a Dull Riven Slate Tiles
The cleaning process was split into two main components. Firstly, I scrubbed a strong dilution of Tile Doctor Pro Clean into the tiles to remove the initial layers of soil buildup. Pro Clean is our go-to cleaner for most natural stone due to its reliability and the fact that, unlike a lot of supermarket floor cleaners, it isn’t acid-based and so won’t damage the stone.
Since the ingrained dirt problem was quite severe, I opted to also clean the tiles using our van-mounted pressure cleaning system. This very efficient system applies hot water under pressure to the to stone to penetrate deeply and eradicate particularly stubborn ingrained dirt. It then automatically extracts the soiled water back into a tank in our van.
Sealing Riven Slate Tiles
To seal the tiles I used four costs of Tile Doctor Seal and Go. This is a topical sealer, meaning it forms a robust layer of protection on the surface of the tiles. Seal and Go also helps to enhance colour while providing a natural look matte finish that complements the natural stone.
