Details below of a tired Slate and Flag Stone floor installed in a house in Cookham, Berkshire; the client was actually the son of an existing client whose floor we had also cleaned recently. The existing sealer had been wearing away over time and the floor had becoming increasingly ingrained with dirt making it difficult to keep clean, the solution was to strip the floor back and re-seal it.
Stone Floor Cleaning
To clean and strip the tiles of the remaining sealer the floor was soaked in a solution of Tile Doctor Pro-Clean and scrubbed in using a weighted rotary machine to help loosen the soils and break down the sealers. The soiled solution was removed and it was clear some areas of the floor needed further attention to remove the sealer so an application of Tile Doctor Remove and Go was applied which was left to soak in for a while to assist in breaking down the sealer before being scrubbed again. Once the floor was clean and the sealer was gone the floor was rinsed using our hot truck mounted extraction system and was then allowed to dry for 36 hours.
Stone Floor Sealing
When we returned I checked to make sure the floor was dry and ready to seal, all was well so I then sealed both the Slate and Flagstone floors with six coats of Tile Doctor Seal and Go using a paint pad applicator.
The floor looked much improved when finished I took time to explain how to clean the floor using a Neutral Cleaner that will extend the life of the sealer, the customer was pleased with the service and left the following comment on the Tile Doctor feedback system.

This 50 m2 Limestone tiled floor at an old thatched cottage in Slough had unfortunately been stained following a radiator system leak which covered the tiles in dirty radiator water and sludge. The limestone tiles had been laid on a floor without a screed damp proofing membrane which resulted in the release of efflorescent mineral salts rising up through the stone from the soil beneath. This left a constant layer of reforming fine salt on the surface of the stone which looked like fine dust. The water had also damaged the surface of the stone leaving patches of dull etched stone next to clean polished areas.
Stripping the Limestone Tiled Floor
To encourage the stone to dry out thoroughly we left a number of dehumidifiers in the room for a week and increased the room temperature. Once the stone was dry, it stopped releasing effloresce salts and we were able to restore the surface polish by burnishing the floor.
Burnishing involves stripping back the Limestone surface using a set of burnishing pads, these diamond encrusted pads come in a number of grades and each one does a different job. I started with the coarse pad together with water removed the slurry with a wet vacuum, rinsed the floor and then carried on with the medium, fine and super fine pads using the same processes until the surface was polished again. Finally when I had dried the floor I used a green buffing pad to buff the floor up.
Sealing the Limestone Floor
The next step was to seal the Limestone with a couple of coats of Tile Doctor Colour Grow which will provide a durable protective sealer against future staining. The result was an even, polished limestone tiled floor with a durable sealing to protect against future soiling and staining.
