Limescale Removal

Limescale Stained Slate Shower Floor Renovated Penn

Removing Limescale from Slate Wet Room Tiles in Penn

This is a great example of what we can achieve with very stained Slate Tiles so well worth sharing. The customer was from Penn in Buckinghamshire and as you can see from the photo below the Slate tiled floor in their wet room was heavily stained with thick limescale mainly around the shower trap where the water collects.

Buckinghamshire is known for its hard water problems which basically means the water contains high levels of calcium carbonate. These deposits are carried in the water and left on the tiles after each shower resulting in Limescale. You can reduce the problem by installing a water softener and it can be dissolved using some of the strong products you find in supermarkets however these are acidic and can etch natural stone if you are not careful. Always read the label!

In this case my customer had just moved into the house and wanted to improve the look of the bathroom and then eventually they planned to change the whole bathroom itself, but in the meantime wanted it cleaned and restored.

Cleaning a Slate Tiled Shower Floor

To renovate the Slate tiles, I started with the application of a strong dilution of an alkaline product made by Tile Doctor called Pro-Clean. This is a great grout cleaner and when used as a strong dilution it will also strip off any sealer remaining on the Slate.

I used the usual method of spraying the Pro-Clean onto the tile and grout and leaving it to soak in for at least ten minutes so it can get to work. It was then scrubbed in with hand tools and an 80-grit silicon carbide brush which is a very effective combination. This gave the stone a deep clean and removed some of the thick limescale on the tiles which was rinsed off with water.

Once the floor had been cleaned and stripped back, I used another Tile Doctor product called Grout Clean-up which is an acidic cleaner and is applied in the same way. Because the build-up of Limescale was so thing I found that a lot of pressure was needed when scrubbing the tiles and, in some areas, I needed to use a scrapper to take off the top layer.

After cleaning off all the limescale and giving the stone a good rinse, I dried the floor using a white rag and left it to dry off so it would dry enough for sealing. After giving the floor time to dry I used tile doctors oil-based sealer called X-Tra seal putting down a thick coat and allowing the tiles to soak up the sealer. After some time, the floor was then buffed with a cloth to remove the excess and then a second coat was applied.

X-Tra Seal adds the oil back into the stone which restores the dark tones and bring out the natural colour in the Slate, its also rated for external use so will cope well with the damp conditions of the wet room. After that coat had dried a 6-inch 1500-grit buffing pad was used to remove excess sealer and add a slight sheen to the floor.

The fresh sealer should make the Slate less prone to limescale deposits however its not going to prevent the problem indefinitely. Also, for the aftercare of sealed shower tiles, I recommend Aqua-Pro which is a mild cleaning product designed for regular use and won’t harm the sealer like many of the stronger products you find in supermarkets.

Slate Shower Floor Tiles Before After Limescale Cleaning in High Wycombe

Removing Limescale from a Slate Shower Floor in High Wycombe

I received this enquiry from a client in High Wycombe who needed the Slate tiled shower floor cleaning. I visited site to view the problem and it turns out this was a bit of an understatement; the whole floor was completely covered in limescale, and this had turned the Slate tiles white over time.

Limescale Stained Slate Shower Floor Before Cleaning High Wycombe

Limescale is a big problem for High Wycombe which is classed as a hard water area which basically means the water contains high levels of calcium carbonate. These deposits are carried in the water and left on the tiles after each shower. You can install a water softener to alleviate the problem but that won’t solve this client’s current issue. There are numerous limescale removal products that you can buy in supermarkets however these are acidic and can etch natural stone if you are not careful. Always read the label!

Cleaning a Slate Tiled Shower Floor

The limescale build up on this floor was really bad so I felt the best approach would be to use a light acidic cleaning product to help remove the worst of it and then to refinish the appearance and removing any etching of the tiles using a series of diamond encrusted stone burnishing pads. I provided the client with a quote based on this solution and it was accepted.

To start removing the limescale I applied neat Tile Doctor Grout Clean-up which is an acid cleaner that can remove grout smears and other mineral deposits such as in this case calcium carbonate deposits. I then used my handheld polishing machine with a very coarse 80-grit diamond brush attached and scrubbed it to remove the crust of the limescale.

I then applied more Tile Doctor Grout Clean-up and watched the remaining scale fizz away; the floor was then rinsed to remove the soil using water and our wet vacuum. The next step was to apply a 400-grit six-inch diamond pad, again fitted to the hand polisher to buff the floor and prepare it for the new seal.

After waiting for the stone to dry I was able to finish the floor with a fresh sealer. For this I applied one coat of Tile Doctor Colour Grow which was left to soak in and then buffed with a clean cloth to remove the excess. I then applied one coat of Tile Doctor Stone Oil to restore the natural oil in the stone and buffed this in, I then finished with one more coat of Tile Doctor Colour Grow and buffed the floor with a 3000-grit diamond pad to bring up the polished appearance of the stone even further.

The client was delighted with the restoration and surprised at how we had managed to shift the limescale. the shower looked a lot more inviting! For aftercare I recommended cleaning with Tile Doctor Stone Soap which will help build patina and maintain the polished appearance of the stone.
