This is a polished Limestone floor in the reception area of an office in the town of Wilmslow that had been installed around ten years prior. As you can see they were now in a poor state with ingrained dirt and cracks across the surface of some of the tiles.
Deep Cleaning Limestone Tile and Grout
The polished Limestone tiles needed to be cut back and refinished with a set of diamond encrusted burnishing pads however my first task was to clean the grout lines by applying a medium dilution of Tile Doctor Pro-Clean and scrubbing it in with a stiff narrow brush. I gave the grout a rinse with hot water and removed the now soiled water with a wet vacuum.
The next task was to start the burnishing process by running a course pad fitter to my rotary machine over each tile lubricated with a little water. The coarse pad removes the dirt from the Limestone and resultant slurry is washed away with more water and the wet vacuum. This process is repeated with the “medium” and “fine” polishing pads which restore the surface and build up the polish back on the tile.
Before moving onto the final polishing pad I tackled the large cracks in the tile by filling them with a colour matching resin. There could be a number of reasons for the cracks but typically it would indicate some sort of movement in the subfloor. A common cause is due to the concrete base was not being given sufficient time to dry out before being tiled over and shrinkage in the concrete as it dries caused movement.
Repairing and Sealing Limestone Tiles
Once the resin had dried I moved onto to apply the final “Super Fine” polishing pad which brings up the polish on the Limestone to that final deep level again using a little water and rinsing down afterwards.
Once the floor was dry it was then sealed with two coats of Tile Doctor Colour Grow which is an impregnating sealer which penetrates into the pores of the stone protecting it from within, it also had the added benefit of bringing out the natural colours in the stone enhancing the look of the floor.

This was an unusual request to clean a modern piece of contemporary artwork by New York City artist Mel Kendrick on display in one of the gardens of the Wormsley Estate. I’m no art expert but having done some research on the internet it appears to be part of a collection known as “Markers” that were on display at the Madison Square Park in 2009. The work is made from concrete cast into different coloured sections and fitted together to form a rather larger piece of art which having been exposed to the UK elements was now starting to discolour and go orange in part.
Cleaning Modern Concrete Artwork
Being such a prestigious work of art i had to be careful not to damage the stone in anyway so after careful consideration I worked out a process using an alkaline cleaning product Tile Doctor Pro-Clean.
To get the statue clean I used a warm water dilution of Tile Doctor Pro Clean working it into small areas at a time spraying the solution on and scrubbing with a brush, then rinsing it off with clean water. This process took some time but certainly did the trick.
Sealing a Concrete Artwork
With this project being outdoors and with it taking a couple of days I had to pick a good weather window and fortunately the weather held out long enough so I could continue and seal the concrete in order to protect it going forward. Again careful consideration had to be given to the choice of sealer and in the end I went with Tile Doctor Ultra Seal which is an impregnating sealer that soaks into the pores protecting from within and most importantly it’s a natural look sealer that does not change or enhance the colours.
If you’re a lover a modern art then you should appreciate the difference and will agree with me that the statue now looks new again.

We were engaged by a commercial maintenance contractor to clean the large Limestone reception floor area of a very prestigious office building in the centre of Cardiff. The office’s main tenant is a bank and the owners were keen to restore the floor as they were letting out the remaining office space and keen to show off its potential to other businesses. The Limestone floor had been laid in 2009 and naturally being a reception area had seen a lot of foot traffic and the standard cleaning process was struggling to keep pace with the ingrained dirt and would now need to be burnished with diamond encrusted pads to remove the ingrained dirt and bring back the polish.
Restoring Polished Limestone
First went over the area with a very course black burnishing pad fitted to a rotary cleaning machine and a little water to remove the worst dirt and cleaned the grout lines with Tile Doctor Pro Clean in the process with a stiff grout brush. For stubborn areas I mixed in a little Tile Doctor Nanotech HBU which deals with the heavy build-up of dirt, rinsing and extracting the soil with a wet vacuum as I worked.
Once the main ingrained dirt was lifted I moved onto the a medium burnishing pad which is the first step in restoring the surface back to its normal appearance; this was followed with the next pad in the sequence all the time lubricating with water as you go. The floor was then given a thorough rinse to remove any soil created by the processes and left to dry overnight.
The next day the floor was given a final polish with the last burnishing pad which is super fine and then it was sealed including the grout lines with a couple of coats of Tile Doctor Colour Grow which impregnates the stone to prevent contaminates becoming ingrained into the tile, it also enhances the natural colours in the stone. Last step was a final run over with a buffing pad to ensure any blemishes were removed.

This call actually came from a cleaning company where one of their cleaners had been to a customer in the village of West Hanney near Wantage and tried to clean the walls of this Limestone Shower using a supermarket Limescale remover, which as you can see from the photograph below didn’t work out very well.
I should point out that Limescale removers contain some strong acids which should never be used on stone or sealed surfaces as the acid will etch the surface. Even weak acid cleaners used over time will have an effect so do take care and always read the label.
Resurfacing Limestone Shower Tiles
To restore the surface I realised it would need to be treated like a polished stone floor and burnished. So with this in mind I started burning the tiles with a little water and a coarse 6 inch diamond burnishing pad fitted to a hand held rotary machine before moving onto a medium pad. Normally to bring up the polish you would move onto the fine and super-fine pads but it was evident that the other shower walls had a matt finish so there was no need.
Sealing Limestone Shower Tiles
I waited for the Limestone tiles to dry and applied two coats of Tile Doctor Ultra Seal which is a penetrating sealer that will protect the stone from staining.
The owners of the house were very pleased that the wall was not ruined and the cleaning company relieved that the problem had been resolved.
