Repairing Cracks in Limestone Tiles

I appreciate my photography is not the best but hopefully if you take a close look at the lower half of the picture below showing a dull Limestone floor tiles you can see a couple of long cracks in the tiles. The picture was taken at a house in Hornchurch which is in the East End of London; we had been asked round to see if we could repair the cracked tile and put some new life into the floor.

Cleaning and Repairing a cracked Limestone floor

To begin I gave the floor a thorough clean using Tile Doctor Pro-Clean worked in with a black scrubbing pad fitted to a rotary machine. I wanted the floor clean before I tacked the cracked tiles and this would also ensure any grit etc. would be removed from the floor before I started the polishing process. After cleaning the floor was rinsed with water and the soiled cleaning solution extracted using a wet vacuum. I should mention Pro-Clean is a versatile, alkaline cleaner recommended for cleaning natural stone floors such as Limestone. The crack was then filled using a special stone glue and hardener.

Polishing a Limestone tiled floor

Once the glue had hardened we started to restore the appearance of the Limestone using a set of diamond encrusted burnishing pads which you apply in sequence from coarse to super fine with a little water for lubrication and a rinse with water in between. It takes a while to do but it does a great job of bringing back the polish on the tiles.

Once we were finished burnishing the next step was to apply Tile Doctor Shine Powder into the tiles, the shine powder is worked in using a white buffing pad attached to a rotary machine running on slow speed. It adds more depth to the polish and forms a very durable finish.

Last step was to finish the floor by sealing it with Tile Doctor Colour Grow, Shine Powder works as a sealer too but Colour Grow gets deep into the pores of the stone protecting it from within and enhancing it’s natural colours.

As you can image the owner of the property was very happy with the results and with the added protection of Shine Powder and Colour Grow it should stay that way for some time to come.

Repairing Cracked Limestone Floor Tiles

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.

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.
