Restoring Quarry Tiles
The first process was to tape the newly papered wall to protect them from any splashes during the cleaning process. I then scrubbed in a dilution of Tile doctor Pro-Clean with the assistance of a rotary floor machine fitted with a black pad and then rinsed off the resultant slurry. This process defiantly made an improvement but I can see more work would be needed so I then applied a mixture of Pro-Clean and HBU (Heavy Build-up Remover) to the floor and scrubbed this with a carbon brush attached to a rotary floor machine. This proved to be more effective removing the carpet glue marks so I then rinsed the floor with water and used my wet vacuum to remove the slurry. I then gave the floor a thorough rinse with water again using the wet vacuum to extract the solution afterwards. To finish the cleaning of the floor and remove any grout smears and other minderal deposits I applied Tile Doctor Acid Gel to the floor; this was left to dwell for a short time before scrubbing in with a stiff brush and then rinsed away with more water and extracted again using the wet vacuum. The last job of the day was to fill in some holes in the tiles with a colour matching resin filler.Sealing a Quarry Tiled floor
I returned two days later and confirmed the floor was dry ready for sealing. To seal the floor I first applied a coat of Tile Doctor Colour Grow which is an impregnating seal that also enhances the colour of the stone. This leaves a Matt finish and I showed the client this as they was not sure what finish they wanted, after seeing this that wanted more shine to the floor so once dried I applied a couple of coats of Tile Doctor Seal & Go which is a topical sealer that gives a sheen finish to the floor.The client was very pleased with the end result leaving this as feedback. Our options were a completely new floor or renovate the existing quarry tiles. We were glad we chose renovation; the results are amazing and a lot less messy and expensive than a new floor!
