Acid damaged black limestone patio tiles in Bromsgrove


A local company in Bromsgrove were commissioned to lay a stunning and expensive Black Limestone patio for a customer who was renovating their property. Unfortunately, the company tried to clean the finished patio with brick acid, and because limestone is generally very porous and acid sensitive this discoloured the tiles to a rather unsightly, dull grey – a far cry from what their customer was expecting!

The company facing a large bill contacted Tile Doctor for expert advice to see if the beautiful tiles could be restored. If Tile Doctor couldn’t come to the rescue, then the company would have no choice other than to replace them at their own expense.

Black limestone paving has become incredibly popular over the last few years as its dark tones suit the current trend for a monochrome palette. It is also hard wearing and readily available.

Tile Doctor specialise in the restoration of all types of tile and stone and as their local agent, I was asked to go over and see what could be done. I realised that the brick acid will have damaged the surface of the stone so to restore it I first tried applying a coarse 200 grit diamond burnishing pad. The pad successfully demonstrated that the appearance could be restored and impressed with the difference the site foreman booked me in to complete the whole patio. Luckily the weather forecast was set fair for a few days, which would be needed to clean and seal the patio.

Made with industrial diamonds and available in different sizes and grits, burnishing pads are ideal for restoring the appearance of polished stone floors. The first step was to work on the tiles with a course 200 grit diamond pad fitted to a weighted rotary machine and lubricated with water. This took off a layer of the limestone, bringing back the original black appearance of the tiles.

Next the patio was worked on with 400 grit diamond pads followed by 800 grit pads – the first stage of polishing – and each application was cleaned off with water. Because the property was being renovated there was a lot of dirt on the tiles and grout from construction, so I scrubbed in medium dilution of Tile Doctor Pro-Clean using a CRB (counter rotating brush) machine. Once done I rinsed down the area with more water and left it to dry. As you can see from the pictures it was a large area, so this work took two days to complete.

Sealing Limestone Patio Tiles to Restore Colour

I returned the next day to start the sealing process beginning with the application of Tile Doctor Stone-Oil which restores the deep black colour and texture to the limestone, it’s also an impregnating sealer that adds protection and improves mechanical strength once cured.

I allowed this to dry for 24 hours and then applied a coat of Ultra-Seal, a no-sheen natural-looking sealer formulated to provide maximum stain protection.

The customer was very happy with the results. The patio tiles were fully restored to their original glory and their customer was delighted. More importantly, the company had been saved from making an insurance claim. They left the following feedback on completion:

Restoring a Carpet Covered Terracotta Tiled Floor in Appleton


I was contacted by a home owner in Appleton near Warrington who had a Terracotta tiled floor in their dining Room. The floor had previously been covered in carpet and they were keen to have the whole floor restored.

To complicate things further the Carpet had been stuck down with a strong adhesive and a local builder had advised them to remove the glue using brick acid. Although this was successful it had the side effect of discolouring the grout lines and no amount of rinsing with the floor with water to dilute and wash off the acid would resolve the problem.

Happy for me to resolve the problem, my client informed me they were going on holiday and would like me to do the work whilst they were away. This was a great idea as it would guard against unwanted foot traffic during the cleaning and sealing process and it would also mean they would have a nice surprise waiting for them on their return.

Deep Cleaning a Terracotta Tiled Kitchen Floor

After protecting the Kitchen units and skirting boards with plastic sheeting my first job was to strip any remaining sealer off the Terracotta tiles using a strong dilution of Tile Doctor Pro-Clean. The solution was spread across the floor and then left to dwell for twenty minutes before scrubbing it in with a black scrubbing pad attached to a rotary floor buffer. I then used a wet vacuum to remove the now dirty cleaning solution from the floor.

The grout was also given a good scrub using more Tile Doctor Pro-Clean but this time it was scrubbed in with a narrow stiff brush until I was satisfied it was as clean as it could be. The floor given a good rinse and I then inspected the floor tile and grout to ensure it was clean and free of sealers, any areas that needed ore work were retreated and the floor given a final rinse and dry with the wet vacuum before being left to dry off fully overnight.

Sealing a Terracotta Tiled Kitchen Floor

I returned the next morning and tested the tiles with a damp meter to ensure they were dry before beginning applying the sealer. All was well, so I started by applying a single coat of Tile Doctor Colour Grow. Colour Grow is an impregnating sealer that seeps into the pores of the tile protecting it from within and enhancing the natural red colour of the Terracotta in the process.

Once the first coat had dried I followed up with two coats of Tile Doctor Seal and Go which is a compatible water-based sealer that works really well on clay tiles and adds a lovely sheen finish to the floor.

The last step was to resolve the problem with the discoloured grout lines by applying a white grout colourant to the grout. This gave the grout a fresh and consistent appearance throughout and also has the benefit of sealing the grout which will protect it from staining and also make it much easier to clean.

Last step was to finish the sealing of the floor by topping up the sealer with another three coats of Seal and Go to ensure the floor was fully sealed.

The result was a huge improvement and now looked like a recently installed Terracotta floor. When my customer returned from holiday they were more than happy with the floor and the work I had done.
