Mould-stained Marble Tiled Bathroom Restoration in Twickenham

As you can see from the photographs below this Marble tiled bathroom at a property in Twickenham had a very bad case severe case of mould staining. The client was trying to decide if the tiles were too far gone for restoration after letting a property for the past 4 years, the tenants unfortunately didn’t let him know the state of things.

Keen to have the problem resolved quickly I managed to move some things around called into the property the following day. I was confident that the mould could be removed however you do need to be careful with Marble as its acid sensitive, also I could see the tiles had a factory seal so proceeded with caution and was able to demonstrate that the problems could be rectified.

Happy with the proposed solution and keen to get the property back on the rental market I was immediately booked to return the following week.

Cleaning Mould from Marble Bathroom Tiles

Day one for this job was to remove all mould from the tiles. To do this I lightly rubbed Tile Doctor Acid-Gel into small sections of the tiles until I could see the clean surface and then immediately washed off with clean water, making sure I got every part of the tiles to avoid any runoff.

Work proceeded in this manner until all the tiles free of mould and dirt. With the mould staining removed I noticed some of the tiles were effected by grout haze which happens when the tiler fails to polish off all the grout during installation. It wasn’t part of the initial quote however I felt obliged to deal with it so more Acid Gel and elbow grease was applied until that was removed allowing the details of the Marble tiling to come through.

Next step was to treat the grout lines using a similar process with Acid Gel but for this I used a wire brush to remove surface staining leaving the grout clean and returning the grout lines to their original colour.

To bring up the appearance of the Marble tiling a six-inch 1500-grit burnishing pad fitted to a handheld machine was run over each tile several times using only water for lubrication. This was then followed with a very fine 3500-grit pad to bring up the polish.

Once I was happy that the finish on the Marble tiles was as good as it could get, I then re-inspected the grout and decided to replace some areas of grouting that had suffered deep staining. I used a coloured grout to match what was originally there.

Last step before leaving for the day was to strip out all the silicone sealant from the wall verticals and along the bath and allowed the joints to dry overnight.

Applying a Grout Colourant to Marble Bathroom Tiles

The next day I returned the next day to finish the project off starting with an inspection to ensure nothing had been missed. At this point I felt the grout could still be improve so all grout lines were coloured with a Tile Doctor Grout Colourant to ensure a consistent appearance. I was hoping to avoid this but I felt it was the best solution to bring the bathroom to an “as new” appearance. The colourant also acts as a barrier over the grout making it much easier to keep clean.

Last step was to apply new mould resistant silicone sealant to the verticals and along the bath which finished off the project nicely. They still had some work to do including painting the ceiling but from my point of view I was very happy with the way the Marble tile and grout had responded to the treatment.

My work was done so I called the client who was keen to come over and look. To say they were shocked is an understatement, they were considering ripping all the tiles out and replacing but luckily, we saved them a small fortune. For aftercare I advised increasing the ventilation and using a mild cleaning product such as Tile Doctor Aqua Pro.
