This Quarry tiled floor in Milton Abbas, Dorset was over 200 years old and had suffered from various attempts at maintenance over the years. Built at a time before the invention of damp proof membranes there was evidence of efflorescence where damp had risen up through the floor and deposited salts on the tile surface leaving white staining.
Cleaning and Efflorescence removal
Tile Doctor Grout Clean-Up was applied to remove the Efflorescence, it’s an Acid based product more commonly used for the removal of grout from the tile surface but also just as handy for the removal of mineral deposits, rust stains as well as efflorescence; I should warn that you can’t leave the product on the tile surface for too long as being an Acid it can damage the tile so it needs to be washed off with clean water soon afterwards.
Once we had tackled the efflorescence problem we set about cleaning and neutralising the floor using a dilution of Tile Doctor Pro-Clean mixed 50/50 with NanoTech Ultra Clean which adds nano sized abrasive particles to the solution to make a more effective cleaner. We allowed this to dwell for a short while before agitating it with a rotary machine fitted with a black scrubbing pad working the solution into the floor. Once we were happy with floor it was washed down with a high pressure spinning tool which is a special floor cleaning machine. Once clean the dirty solution was removed using a Vet Vacuum and then left to dry.
Sealing Quarry Tiles
When the floor was dry we applied Tile Doctor Seal and Go which is a specially formulated water-based blended sealer ideal for Quarry tiles that provides both a stain resistant surface seal with a durable low-sheen finish, six coats were required to completely seal the floor.
