Removing Varnish From Grout in Harrogate

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.

Restoring Discoloured White Grout

Recently, I was called to a work on a Limestone tiled floor in a house near Hove Park. Hove Park is a popular park in Hove, East Sussex, which was once opposite to the Goldstone Ground, the traditional home of Brighton and Hove Albion football club until the ground was demolished. My client informed me that the house was used a meeting place every Friday, and the high traffic of people was taking its toll on the floor.

Cleaning a Limestone tiled floor

The floor was clearly in need of a good clean, especially the grout. You do need to take care when cleaning Limestone as it can be affected by the acidic substances you get in some cleaning products which can break down the surface of the Limestone and cause further damage. The results of my test clean showed the Limestone tiles responded well to the cleaning, but I was concerned about the grout, which was not cleaning very easily. I suspected that the grout had, in fact, been discoloured by a bleach-based cleaner, turning it grey. Bleach contains strong chemicals, so there is a good chance that any bleach-based cleaners used on tiled floors will discolour the grout over time. After discussing this issue with my client, I quoted separately for a possible grout recolour.

On the first day of working on the floor, I started the cleaning process using a black buffing pad attached to a floor buffer machine, in combination with a solution of Tile Doctor Pro-Clean, which I applied to the floor. This combination really helped to remove the heavily built up grime and dirt. Although the tiles looked great after the clean, I still wasn’t convinced by the state of the grout. After drying a test area with a heat gun, I confirmed that the grout was not continuous in colour and would need a recolour to get it back to looking its best again.

Recolouring the grout

I left the rest of the floor to dry for a period of two days, allowing any residual moisture to evaporate, before returning to recolour the grout with a white Grout Colourant which was applied using a good old fashioned toothbrush and baby wipes to remove any excess. I was careful to apply thin, even coats in order to prevent the possibility of the Colourant staining the tile.

After several hours of knee-breaking work, the recolouring was complete, and I was extremely pleased to be able to show my client the finished product. She was very happy to be able to show off the floor to her friends, which was now white all the way through, without the dark lines caused by the discoloured grout.
