Brazilian Slate is amongst some of the highest quality available in the world and the grey variant is particularly striking when used for large areas of flooring. I mention this as I recently encountered a fantastic Grey Brazilian Slate tiled floor in what turned out to be one our largest domestic restoration projects to date.
Fortunately, the customer arranged to have all furniture moved into storage, so we could have a clear area to work on and were able to get straight to work on arrival.
Cleaning a Brazilian Slate Tiled Floor
Due to the size of the job, the cleaning process was carried out over the course of four days by two Tile Doctor technicians on site. Our first course of action was to mix a strong solution of our reliable high-alkaline cleaner, Tile Doctor Pro-Clean. The solution was applied and agitated into the tiles and grout using specialised grout brushes and a rotary machine with a 17” black scrubbing pad. This not only cleaned the tiles but also removed any old sealant remaining on the floor.
The resulting slurry was quickly soaked up using a wet vacuum. We then applied a dilution of Tile Doctor Grout Clean-Up to all the grout lines, brushing the product in with grout brushes and using the wet vacuum to remove any excess chemicals. Grout Clean-Up is a concentrated phosphoric acid cleaner which removes grout smears from the surface of the tile to ensure there’s nothing that can detract from its natural appearance.
We rinsed and mopped the floor with plain water to neutralise the floor in preparation for sealing and performed a final go over with the wet vacuum. Each area was dried with fans and the cleaning process began again in the next room. This work was repeated in each area as we moved from room to room.
Sealing a Brazilian Slate Tile Floor
Each area was given at least 24 hours to dry before sealing and then sealed with five coats of Tile Doctor Seal and Go sealant. This sealer works really well on Slate adding robust protection whilst achieving a light sheen finish which gave the customer the look they were hoping to achieve.
“Excellent service. Very friendly and very professional. I would certainly recommend.”
