The photographs below of a Honed Limestone tiles fitted in the living room of a house in Marlborough. The tiles were proving difficult to keep clean especially around the high traffic areas such as the doorway, I suspect the sealer had worn down and dirt was now becoming ingrained in the pores of the stone.
Cleaning Limestone Floor Tiles
The first job was to remove any surface dirt and get the grout clean so a strong dilution of Tile Doctor Pro-Clean was mopped onto the floor and left to dwell for around ten minutes before being scrubbed into the tile and grout lines with a stiff brush. We then removed the dirty cleaning solution with a wet vacuum and rinsed the floor with clean water.
The next step was to burnish the Limestone tiles using a set of diamond burnishing pads starting with the coarse or number 1 pad as it’s known. This is run over the stone in conjunction with a little water and is designed to remove old sealers and other surface coatings and clean at the same time. The resultant milky slurry is the removed using a wet vacuum and the floor rinsed before repeating the whole process with the medium (number 2) pad and fine grade (number 3) pad. The Limestone tiles were then given a final rinse and left to dry overnight. I should point out the Limestone was honed as opposed to polished so there was no need to apply the final pad which is used to bring up the polish on stone.
Sealing Limestone Floor Tiles
I returned the next day to seal the floor checking first that it was dry by taking multiple readings with a damp meter. The result were fine so I was able to move quickly onto sealing the floor for which I used two coats of Tile Doctor Colour Grow which is a versatile impregnating sealer that occupies the pores in the stone preventing contaminates from lodging there and enhancing the colours in natural stone.
Limestone Floor Burnished, Buffed and Sealed in Wiltshire
This was an unusual problem; a customer contacted us regarding their Marble shower room at a house in Marlborough where the customer had sprayed Viakal Limescale remover onto the Marble tiles to clean them which unfortunately etched the surface. I’ve downloaded the MSDS sheet from the Inernet for this product and can verify it contains a combination of Etidronic, Formic and Phosphoric acids so not a very safe product to use on Marble or any sealed stone surface.
Cleaning Marble Wall Tiles
To remove the etching the Marble tiles were burnished using a 6inch coarse diamond encrusted burnishing pad fixed to a hand held rotary machine and lubricated with a spray bottle of water to help keep tiles wet. Burnishing pads come in a set of four from Coarse, Medium, Fine and Super Fine so once we had removed the etching using the coarse pad we then applied the next pads in turn which re-polish the area back to its original shine. Between pads we rinsed the tiles down to remove any soiled water away; after the final super fine pad was applied the shower tiles were given a thorough rinse down ready for sealing.
Sealing the Marble Wall Tiles
The wall was wiped down and left to dry overnight and we returned the next day to seal the Marble tiles using two coats of Tile Doctor Colour Grow which will protect the tile against water marking and staining from toiletries. I explained to the customer that the best way to protect the sealer was to simply use the shower head to rinse the walls every time you shower; Tile Doctor also sell an everyday cleaning product for use with showers called Aqua-Pro which is a mild alkaline cleaner that can remove body fats and stains from shampoo and soap products etc.
Burnishing the Marble tiles resolved the problem so all is well however if you have a natural stone or sealed tiled surface in your house be warned and always read the label of cleaning products before you use them; if in any doubt do give Tile Doctor a call we are always ready to advise.
