These Limestone tiles, installed in a lovely residence in the ancient market town of Oswestry close to the English/Welsh border, had become dull and dirty over the years and I was asked to get them looking their best again. When I arrived to do the quotation the customer’s main concern was that the grout lines had become dirty, but when I completed a test clean on one tile and the grout around it they realised the tiles themselves were dirty and had lost their shine to become a mat finish.

Cleaning Limestone Tiles
It was a large floor so working in sections I gave the floor a general clean using a mild dilution of Tile Doctor Pro-Clean which was spread over the floor with particular attention paid to getting the solution into the grout lines. The solution was left to soak in and eat through any dirt and a stiff grout brush was run along each grout line giving it a good scrub along the way. Next we removed any trace of product by using a wet vacuum to extract the now dirty cleaning solution and rinsed thoroughly with clean water.
There were a couple of holes in the Limestone that needed attention so these were filled with a matching colour. The next step was to use a set of diamond encrusted burnishing pads which attach to a rotary machine and burnish the floor with four different grits from coarse to super fine. To remove any remaining sealer and dirt the floor is burnished using a course pad and a little water to help lubricate passing over each tile around four times in the process. The resultant soiled water is rinsed away with clean water which in turn is removed using a wet vacuum. This process is then repeated with the remaining pads, rinsing between each pad until a nice polish is built up on the tile. I managed to finish with the 2nd and 3rd pads but it was getting late to completely finish the polishing so called it a day.
Sealing Limestone Tiles
When I arrived on the second day to finish the polishing process with the fourth super fine polishing pad and seal the floor the customer thought I had already finished polishing and was already happy with the shine we had achieved so far, so you can imagine how happy she when I told her there was more to do. Once I had finished polishing I applied a single coat of Tile Doctor Colour Grow which impregnates the pores in the stone to prevent other contaminates getting in there; Colour Grow also does a great job of bringing out the natural colours in the stone.

The customer was very happy with the end result and
Its a fact that Natural stone floors such as Limestone and Travertine will loose their shine over the years; you can either give the floor a quick clean and polish every six month to maintain the shine or have it burnished every few years.
