Here at Tile Doctor we can’t stress often enough how careful you have to be when choosing a cleaning product for use on natural stone. Acid bases cleaners in particular can etch the surface so always read the label before buying. Unfortunately, this customer, who lives in Twickenham, learned this the hard way.
Limescale build-up on shower tiles can be an unsightly problem in hard water areas and this customer’s house cleaner had attempted to treat it with Cillit Bang on their Marble tiled shower room floor. Whilst good at removing Limescale on ceramic tiles, the product is acid-based and in this case caused severe etching to the surface of the Marble.
This customer is not the first to experience this problem with Cillit Bang and we have looked into this before and I can confirm it does say on the back on the bottle that you should not use it on all natural stone including Marble and Granite.
The mistake had really damaged the appearance of this lovely floor however the good news is etched Marble can be refinished and we do offer this service. Fortunately, this customer found us on-line and called us in to rectify the problem as
Burnishing a Marble Tiled Shower Room Floor
With high quality, acid-sensitive stone we find that rather than cleaning with a liquid product, it is lot effective to use a process known as burnishing. This involves the application of abrasive diamond encrusted pads to cut back through the damaged stone. This removes a layer from the surface to expose the undamaged stone, which in then polished.
Using different grades of small diamond pads fitted to a hand buffer I began burnishing the floor tiles. I started the process with a Coarse pad and worked my way through to Medium, Fine and eventually the Very Fine pad. A small amount of lubrication in the form water is used with each pad, but no chemical products are needed, making this a completely natural process. The floor was rinsed with water afterwards to remove any slurry from the polishing.
Sealing a Marble Tiled Shower Room Floor
After allowing the floor dry out overnight, I returned to apply two coats of Tile Doctor Colour Grow, which is a solvent-based, impregnating sealer designed to enhance the variety of natural colours and shades in the stone. It also protects the stone against daily exposure to chemical-based shampoo and soaps.
The customer was worried that the floor could not be restored, but she can now rest assured knowing not only knowing that the floor is back into top condition, but that professional help is at hand in case mistakes happen again in the future! Another happy customer for the Middlesex Tile Doctor.
