When given the right care, a polished Limestone floor can be an amazing asset to any house. If neglected, however, the tiles can quickly discolour from wear, especially in areas of high traffic, such as the kitchen.
Such was the case at this house in the small, picturesque town of Cowbridge, in South East Wales. My client had contacted Tile Doctor to see what could be done to improve the condition of the tile and grout which, as you can see from the photographs had not been properly maintained.
To get the floor back to its best it would need to be burnished which is a process that rejuvenating the appearance of polished stone through the application of different grades of diamond encrusted floor pads from coarse to very fine.
Re-Polishing Limestone Floor Tiles
Before beginning the burnishing process, I made sure to check that there were no inherent moisture issues using a damp meter, the home owner had informed me beforehand that the floor did have a damp proof membrane installed however it is always a good precaution to check and additionally it provides a good baseline for later when checking the floor has dried after cleaning.
Burnishing and Sealing a Limestone Tiled Floor
The Tile Doctor burnishing system consists of four main burnishing pads. I began by applying the coarse pad to the tiles lubricated with a little water, before rinsing the floor and moving on to medium and fine grit pads again lubricating with water and rinsing after each pad. After finishing with the third pad, I paused to rinse the entire area a thorough rinse extracting the resulting waste with a wet-vac machine.
I then paid special attention to cleaning the grout lines, which had turned black in places. I applied undiluted Tile Doctor Pro Clean and agitated the grout lines with a stiff scrubbing brush to restore the original colour. This was followed by another thorough rinse.
Sealing Limestone Floor Tiles
I left the floor to dry overnight, before completing the burnishing process by applying the final very fine grit pad which adds that aesthetically pleasing shine. I used the damp meter to check the floor had dried and once I was happy I began the sealing process with the application of three coats of Tile Doctor Colour Grow. Colour Grow is a great choice for Limestone as it penetrates into the pores of the stone protecting it from within whilst enhancing the natural colours in the Limestone. As a final step and to ensure there were no unappealing marks left on the floor, I went back over the floor once more with the fine grit burnishing pad.
What was once a dull stone floor with dirty grout lines has now been restored back to its original condition and with the correct maintenance going forward should stay that way for some time.
