Cleaning Riven Sandstone Tiles
I cleaned the floor with a dilution of Tile Doctor Remove and Go which was left to seep into the Sandstone before being worked in with a rotary machine fitted with a scrubbing brush attachment. I used a brush rather than a pad since the floor had a riven texture and a flat pad may not have had the desired effect. Tile Doctor is an effective coatings remover ideal for removing sealers for tile, it’s also a good cleaning product having said that there were areas where the old sealer was really stubborn so and I had to retreat those and use steam in the really difficult areas.
Once the floor was stripped back I gave it a thorough rinse with water using a wet vacuum to remove the liquids from the floor and get it as dry as possible.
Sealing Riven Sandstone Tiles
For four days, the floor was left to completely dry out and then I returned to seal it first checking with a damp meter that it was dry. All was as expected so proceeded to seal the stone using four coats of Tile Doctor Seal and Go which is a water based sealer (no smell) and ideal for these types of floor as it offers good protection whilst adding a nice sheen to the surface.
The client was really happy with the result and can now see all the amazing detail and character in this natural stone floor including evidence of fossilised plants.
