The Limestone floor in the picture below was actually installed by the homeowner in the hallway of their property in Leigh-on-Sea twelve years ago. They had managed to do a good job maintaining it however overtime dirt had accumulated in the pores of the stone and they realised it was time to have it professionally cleaned.
I visited the property to survey the floor and provided them with a quote to deep clean the Limestone tile and grout, hone the stone to bring up the polish and then seal to protect it going forward. Happy with the quote we set a date for my return.
Cleaning and Polishing a Limestone Tiled Floor
On arrival the first task was to clean out all the dirt trapped in the pores of the stone. To do this I ran a coarse 200-grit pad over the floor assisted with a dilution of Tile Doctor Pro-Clean. The coarse pads are fitted to a buffing machine and run over each tile several times to remove minor scratches, sealers, and ingrained dirt.
The floor was then rinsed and soiling extracted with a wet vacuum before applying the next coarse pad which was a 400-grit. This process was then repeated with a medium 800-grit and fine 1500-grit pad which are the first stages in bringing up the polish on the Limestone.
Next step was to scrub the grout lines using more Tile Doctor Pro-Clean. I find this is best done by hand as the pads struggle to reach into the recesses of the grout line. Once done the floor was rinsed and extracted several times to neutralise the floor and remove any trace of product.
The floor was then left to dry off overnight.
Sealing a Polished Limestone Tiled Floor
The next day I gave the tiles a spray burnish using an extra fine 3000-grit burning pad, this is applied dry to the floor using only a little water sprayed onto the tile. It leaves the floor nice and dry and is the last step in the polishing process.
To get the best out of the colour in the Limestone I recommended sealing it with Tile Doctor Colour Grow, which as its name implies contains a colour enhancing formula. Its also an impregnator which works by occupying the pores in the stone thus preventing dirt from becoming ingrained there. Two coats were applied and this ensures dirt remains on the surface where it can be easily removed with regular cleaning.
Once done the Limestone tile and grout looked so much lighter and cleaner making the owners very happy. For the aftercare cleaning of a polished stone floor like this we recommend using Tile Doctor Stone Soap. It’s a gentle yet effective cleaner that helps maintain the patina and won’t damage the sealer ensuring it lasts a long time.
