Knaresborough is a historic town in North Yorkshire, popular amongst holiday goers for its numerous attractions. I travelled to the area not to visit the attractions, however, but to visit a customer, whose fantastic white Limestone tiled floor was in need of a deep clean.
Burnishing a Dirty White Limestone Floor
To treat high end, polished stone floors such as Limestone and Marble, we recommend using the process of burnishing. Simply put, burnishing involves the application of diamond encrusted pads of varying grits, which serve to break down dirt and then polish the stone.
Typically, we use a set of four pads in gradual succession; here, I used the first three pads on the first day. Starting with the Coarse grit pad, along with a little water as lubrication, I polished the Limestone, before repeating the process with Medium and Fine pads to refine the polish.
On the same day, I also cleaned the grout using a solution of one part Tile Doctor Pro-Clean (a high alkaline cleaner) and three parts water. On Limestone floors you should take care to avoid even mildly acidic cleaning products as sensitive stones like Limestone and Travertine can be damaged over time. After successfully cleaning the dirt grout lines, I rinsed the floor before using a wet-vac machine to soak up the residue. The floor was then left to fully dry overnight.
Sealing a White Limestone Floor
The next day, I returned to the property to complete the restoration. Before sealing the tiles, I applied the fourth and final of the burnishing pads to achieve a Very Fine polish.
Then, I polished the excess sealer off with a white buffing pad and left it to dry for an hour, before polishing a final time with the Very Fine grit burnishing pad. With this method, the floor was perfectly dry and the customer could walk on the tiles as soon as I left.
