Acid Damaged Negro Marquina Marble Shower Tiles Polished in Thame

I received a call regarding a Black Marble tiled shower that the customer thought he would clean himself and ended up unfortunately making worse. Black Marble adds a very opulent and elegant look to a bathroom, and I suspect this particular variety with the white veins is known as “Negro Marquina” which comes from the Basque region of Spain. I did a quick price check on-line and these tiles are priced around £60 each!

If you look closely at the before picture you can see the Marble has lost its shine and has a cloudy appearance. This was due to the use of an acid based cleaner. Thame and Oxford lie in a hard water area, so we often find customers seek to remove Limescale deposits off tile using household products such as Vikal or Cillit Bang. The trouble with these products is they are acidic, and marble is acid sensitive so is easily marked and damaged by their use. You should always read the label before using any cleaner to check if its safe to use on natural stone.

The client was desperate to get the shower room looking how it should when he had selected this beautiful stone.

Cleaning a Marble Tiled Shower

To rectify the problem and restore the polished appearance of the marble I burnished the stone using a small 6 inch 200-grit diamond pad attached to a handheld buffer. This coarse pad cuts back the stone surface to remove the etching, I then used a 400-grit pad which removed the fine scratches made by the first pad. This was followed up with an 800-grit pad which starts the honing process which restores the polished appearance. Water is used to lubricate the process and the tiles are rinsed with water after each stage to remove the fine slurry that is generated.

This is further followed by 1500 and 3000 grit pads the last pad is applied dry with only a little bit of water and leaves the tiles dry and ready for the next stage.

To further build the polish and protect the stone I applied Tile Doctor Shine Powder buffed in with a white pad. This was applied to the marble wall tiles and then rinsed with water and wiped dry with a clean cloth. When the tiles were fully dry, I buffed the tiles with a clean white pad to show the final polished finish. The tiles looked much improved and very shiny.

The job was completed in a day and the customer was much relieved that I was able to restore the appearance of the marble. I suggested that he should use Tile Doctor Aqua Pro as his tile cleaner of choice in future. This is pH neutral so will not damage the tiles like the acidic products he had used previously, and it should help him keep the shower room looking sparkling and opulent as initially intended!

Restoring the Polish on Marble Tiles

This customer from the town of Brackley near Northampton got in touch with us to discuss their lovely black Marble tiled floor where it was proving difficult to maintain the shine. I went to visit and after carrying out some tests and asking a number of questions it became clear that that the product that had been used for regular cleaning had a high alkaline detergent content which was not suitable for the floor and had been causing smears, there were also light scratches due to the soiling levels. For polished stone or sealed floors we always recommend a neutral PH cleaning product such a Tile Doctor Neutral Cleaner.

Burnishing Polished Black Marble Tiles

To remove the light scratches and restore the shine on the Marble it was necessary to cut back the surface and re-polish with a set of burnishing pads. The pads come in a set of four and are applied in sequence starting with a coarse pad together with a little water to cut through the old sealer and grime. You then progress through the other finer pads one by one until you get to the final polishing pad which provides a high polish.

After polishing the floor was rinsed down to remove any slurry from the polishing process and then allowed to dry before sealing with Tile Doctor Colour Grow which impregnates the pores in the stone enhancing the natural colours and protecting it from future staining.
