I was recently at a property in the North Yorkshire town of Harrogate, undertaking what I initially thought would be the cleaning and polishing of a Cream Limestone tiled kitchen. However, as I began the cleaning process I quickly discovered that under the dirty grout lines someone had taken a lot of effort to paint with a small brush directly onto the grout using varnish!
Removing Varnish from Grout
In a normal situation, I would have covered the whole floor with Tile Doctor Remove & Go to solve the problem, however compared to, say, adhesive or paint staining, varnish is very difficult to remove. So instead I opted for the long, yet necessary process of cleaning the grout manually with several thin wire brushes. Over the course of two days I managed to remove approximately 90% of the stubborn varnish – and could finally move onto cleaning and polishing the Limestone as originally planned.
Burnishing and Sealing a Limestone Tiled Kitchen Floor
The polish had been lost from the Limestone kitchen tiles over time, so I set about restoring it using a type of polishing known as burnishing. This involves the application of diamond encrusted pads of varying grit to the floor to gradually buff the stone and achieve an aesthetic and durable shine. Burnishing is most commonly used on high-end stone such as Marble, Travertine and, of course, Limestone.
At Tile Doctor, our burnishing system comprises four burnishing pads, ranging from a Coarse grit to a Very Fine grit. After applying the first three pads (Coarse, Medium and Fine), I gave the tiles a further clean with Tile a Doctor Pro Clean, which is our alkaline cleaner, to remove any residue from the burnishing process. I then rinsed the floor with clean water and soaked up the residue with a wet vacuum, before leaving it to dry.
The floor was then polished to a satin finish using the fourth and final Extra Fine burnishing pad. I sealed it using a couple of coats of Tile Doctor Ultra-Seal, an impregnating sealer designed to provide maximum protection against dirt and stains.
The combination of burnishing and sealing always makes a huge difference to Limestone tiles. Here, the finished result was almost like a new floor! The customer was both amazed and very pleased with the transformation.
