If you’re passionate about tiled floors and easily upset I suggest you look away now as believe it or not the photographs below are from a recently laid Limestone tiled floor in Banbury. It had been left in a very poor state by the tiler who had managed to cover in Grout Haze and then in the process of trying to rectify the problem by cleaning it off with acid managed to etch the surface of the Limestone making the situation even worse. Limestone being a calcareous stone can in fact be dissolved by acids, in face it’s not unknown for mildly acidic cleaning products to cause holes to appear in the surface over time.
Restoring Limestone Tiles
To resolve we had to strip back the Limestone surface using a set of burnishing pads, these diamond encrusted pads come in a number of different colours each one does a different job from honing to polishing. I started with the coarse pad together with water and then carried on through the set until I got to the finer pad removing the soiled water with a wet vacuum along the way. Finally when I had dried the floor I used a finishing pad to buff the floor up. This activity took most of the day so left the floor to completely dry overnight.
Sealing Limestone Tiles
The following day I checked the floor to make sure it had dried, which it had and started to seal the floor which was done using a couple of coats of Tile Doctor Colour Grow Sealer which is an impregnating sealer which gets into the pores of the Limestone to prevent dirt being trapped, the formula as well as providing stain protection also enhances the natural colours in the stone.
We should setup a Floor Crimes court for this sort of thing and hand out Tiling ASBO’s for all offenders.
