Cleaning, Burnishing and Sealing a Limestone Floor in St. John’s Wood

I was recently engaged to refresh the Limestone tiled floor at a house in St. John’s Wood, which is a very affluent area and apparently has the 5th most expensive postcode in London so as you can imagine this was a very expensive floor. The client had requested an improvement condition of the Limestone tiles in the living room and a thorough clean, polishing and seal was required. Over time, the floor in this busy living room – which was also used as a play area for young children – had become dirty and certainly worse for wear with all the use it had been getting. So, I set about my work to get this floor back to looking its best.

Cleaning and burnishing a Limestone floor

My initial task before beginning the cleaning process was to remove any furniture (as well as toys) from the room so I would have a clear area to work in. I then applied a layer of Tile Doctor Pro-Clean cleaner, diluted with water, to the floor. Pro-Clean is also suitable for use on other natural stone floors such as Slate, Granite and Travertine.

After leaving the solution to dwell for a period of a few minutes, I began to scrub the floor with a stiff hand brush. Whilst helping to remove a lot of the built up dirt on the surface of the tiles, the product also stripped off the old sealer and polish. Following this, I paid special attention to the dirty grout lines, cleaning them with Tile Doctor Oxy-Pro, a powerful, high-alkaline cleaner.

After completing the cleaning, I rinsed the floor with clean water to remove any excess cleaning products. I then began to burnish the floor using Tile Doctor Diamond encrusted burnishing pads. This was done in four steps, as I used four different pads (coarse, medium, fine and very fine) rinsing the floor with water between each pad. I would recommend using this setup of four pads for restoring the appearance of polished stone floors; you starting with a coarse pad and the gradually work your way up to the very fine pad achieving a high polish finish in the process. I finished of the process with a quick rinse and a buffing pad to give the floor a final polish before I commenced the sealing.

My choice of sealer was Tile Doctor Colour Grow, which is specifically designed to not only provide durable surface protection, but also to intensify the colour of the tiles. The sealer penetrates deep into the pores of the stone, providing water resistance and long-term protection from ingrained dirt and stains. As you can see from the photos, the sealer really helped to accentuate the fantastic natural colours in the Limestone.

My client was very pleased with the final result, and was amazed by how quickly I had been able to improve the state of her floor which, with a colourful and shiny finish, has really brightened up the living room.

Cleaning a Limestone Balcony in St John’s Wood

This balcony in St John’s Wood, London, NW8, which had been clad in Limestone floor tiles, had not been professionally cleaned for 15 years and was now covered in mould which the customer was unable to remove.

Stripping the Limestone Tiled Floor

To get the Limestone clean I used a neat solution of Tile Doctor Pro-Clean with was left to soak into the stone before being worked in with rotary machine fitted with a black buffing pad. This process removed most of the mould but there were still some stubborn patches so I then used a further application of Pro-Clean this time mixed 50/50 with Nanotech Ultra Clean to add an abrasive element to what is a powerful alkaline cleaning product. This was scrubbed into the tile and then steamed off using a Bosch steamer followed by further scrubbing by hand.

The next step was to use a set of four Tile Doctor burnishing pads to polish the Limestone surface to a low sheen. These diamond encrusted pads come in a number of different colours and are applied one after another with each pad being a finer grade than the last. After thoroughly rinsing the stone again and removing the waste water with a Numatic aqua vacuum I left the tiles to dry off overnight. Luckily the weather remained fine.

The next day I sealed the Limestone tiles using two coats of Tile Doctor Colour Grow sealer which I prefer for Limestone as it enhances the natural colours in the Limestone floor as well as providing stain protection something I’m sure it’s going to need given the location.

Although not quite all the damage from the mould could be entirely removed the tile was 95% improved and the customer was very satisfied with what had been achieved.
