Natural-Stone Tile Cleaning
The first step was to remove the existing sealer and give the floor a thorough clean; fortunately we were able to do this using a strong dilution of Tile Doctor Pro-Clean which is a multipurpose cleaner/stripper. Pro-Clean was applied to the floor and then left to dwell for a good twenty minutes giving it time to break down the remaining sealer before being worked in using a rotary machine fitted with a black scrubbing pad. To get the grout clean we made up a further batch of Pro-Clean, this time with warm water and scrubbed it by hand into the grout lines using a stiff grout brush. The soiled cleaning solution was removed using a wet vacuum and the floor given a thorough rinse using clean water. Stubborn areas were re-treated using the same process and the floor was left to dry overnight assisted with a turbo air blower.Sandstone Tile Sealing
The next morning we applied three coats of Tile Doctor Seal and Go to the tiles with each coat taking around twenty minutes to dry. Seal and Go is an ideal sealer for natural stone flooring and being water based there are no nasty smells to worry about like most solvent based products. Seal and Go also added a nice subtle sheen to the floor and will protect the tiles for years to come.The customer was delighted with the results.
