Marble Shower Tiles Ruined by Viakal Restored in Ealing

Posted on by

We recently received an enquiry from a customer in Ealing, East London who was concerned about their Marble Tiled Shower which had been damaged from the use of Viakal Limescale Remover. Unfortunately, this is a very common problem and we often receive calls from customers with similar issues. Limescale removal products such as Viakal and Cillit Bang are very effective but like any acidic product, they are very harmful to natural stone such as Limestone and Marble. With any cleaning product you should really read the label before use and in this case you will find they state the product should not be used on natural stone.

The Viakal had etched the surface of the Marble in several places where it had been applied and although the damage looked really bad I was happy to inform my customer there is a solution and that I could indeed restore the appearance of the stone.

Polishing Damaged Marble Shower Tiles

My first task was to give the Marble tile and grout a good clean and remove any sealer and soap scum etc; to do this I used a strong dilution of Tile Doctor Pro-Clean scrubbed in with a small black scrubbing pad fitted to a hand-held machine. The Marble tiles were then rinsed with water to remove the soil generated by the cleaning process.

To fully restore the appearance of the Marble the next step required the application of coarse burnishing pads applied in sequence from very coarse to very fine using six-inch pads fitter to a handheld buffer. It’s a process that takes the polish off the stone and rebuilds it. A little water is needed to help lubricate with the coarser pads and the tiles are rinsed off between each one to remove any slurry generated during the process.

To achieve a very high shine the Marble tiles were then treated to an application of Tile Doctor Shine Powder which involves buffing crystallising polishing powder into the stone to build a deep durable finish

Sealing Marble Shower Tiles

The last step was to seal the Marble tile and grout to protect it going forward. Before sealing we needed to make sure that the tiles are dry and a damp meter is a very useful tool for this. A single coat of Tile Doctor Colour Grow was applied which is an impregnating sealer that occupies the pores in the stone whilst enhancing the natural colours in the Marble in the process.

The work took three days in total but as you can see from the photographs on this page it was well worth the effort and the white streaky damage caused by the Viakal has now been removed and the stone has been transformed. My customer was very happy with the results and left the following feedback.

I had serious acid etchings from spraying Viakal on my marble shower box and basin. Didi and his partner did a good job of polishing out the majority of the acid etchings. It was a 3 day job for them, and over all I was happy with the result and service.

Removing Limescale from Black Marble Bathroom Tiles

Posted on by

This customer in Baldock, North Hertfordshire has a beautiful Black Marble bathroom floor which unfortunately was far from looking its best due to a build-up Limescale. Normally this can be removed with an acidic cleaning product however Marble like all natural stones is acid sensitive would be damaged in the process.

The only way to remove the Limescale would be to polish it off using a set of diamond pads which would also restore a high shine finish to the Marble floor tiles.

Removing Limescale from Polished Black Marble

The first step before starting the process was to cover the threshold edges, skirting’s and doors with tape to protect it from splashing etc. Next we used a medium dilution of Tile Doctor Pro Clean which is an alkaline tile and grout cleaner with hand brushes to clean-up the thin gout lines and remove any grit from the floor.

The floor was then rinsed with fresh water to remove the now soiled cleaning product and also steam cleaned to neutralise floor. The water was extracted from the floor using a wet vacuum.

Honing Black Marble to Restore Polish

To bring back the natural shine we honed the floor using a series of diamond-encrusted burnishing pads. Firstly, I applied a Coarse 400 grit pad to strip away what remained of the old sealer and Limescale, rinsing the floor afterwards. I then applied the Medium 800 grit and Fine 1500 grit pad to gradually close the pores of the stone which, in turn, restores the polished effect. Again each pad is used in combination with a small amount of water and any excess moisture is removed with a wet vacuum. The final 3,000 grit pad brings up a really deep shine and is applied with small amounts of water sprayed onto the tile.

Sealing Polished Black Marble Tiles

After drying the floor the Marble tiles were sealed with two coats of Tile Doctor Ultra-Seal which is a natural look sealer that doesn’t alter the appearance of the stone and protects it from staining by occupying the pores in the stone.

The last step was to buff the Marble tiles with a white buffing pad.

The floor now looks fantastic and you can really see your reflection in the shine of the black Marble tiles.

Dealing With Limescale On Marble Bathroom Worktops

Posted on by

This job required the cleaning of Marble Worktops in twelve toilets at a very nice office in the Abingdon Science Park. The building was occupied by a company called Sophos who you may have heard of and over a period of time the Marble had become stained through the build-up of Limescale from the water supply and the cleaning company servicing the office could not clean it off. I’ve seen a few horror stories of stone surfaces being damaged through the use of acidic Limescale removers so the cleaning company was quite right not to touch it.

Polishing Marble Worktops

To remove the Limescale it would be necessary to hone the Marble using a set of small six inch burnishing pads fitted to a handheld buffing machine. The process involves starting with the coarse 400grit pad with a little water which cuts through the Limescale and then moving on to the 800, 1500 and finishing with 3000 grit to hone the surface and build the polish backup. The water helps lubricate the activity and the surface needs to be rinsed down between each pad.

Sealing Marble Worktops

When the surface was dry I applied two coats of Tile Doctor Colour Grow which is a colour enhancing sealer which impregnates the pores of the stone to protect it, it also enhances the natural colours in the stone.

There were twelve of these to do so as you can imagine it took me a while to get round.

Repolishing Marble tiles in a Hallway in Marlborough

Posted on by

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.
