The owners of this house in the historic city of Oxford contacted Tile Doctor about their Tumbled Marble tiled floor which was not looking its best and was proving difficult to clean effectively. The floor is part of a kitchen/dining room where the grout had darkened substantially with dirt. Oxford is only 12 miles from by base in Chalgrove so I spoke to the client on the phone and arranged an appointment to visit the property and survey the floor.

I could see that sealer had also worn off which is a common problem with natural stone floor and dirt was now trapped in the pores of the stone. They had tried multiple types of household floor cleaners and nothing was getting the floor to look clean, and as it was so light in colour it was really looking quite dirty.

We find the best way to renovate hard stone flooring such as Marble is to use a set of diamond burnishing pads which hone the stone and restore its appearance. I recommended this method to the homeowner and worked out a quote. The quote was agreed, and we set a date to do the work which given the size of the floor I calculated would take two days, one to burnish and one to seal.

Cleaning/Repairing a Tumbled Marble Tiled Kitchen/ Dining room Floor

The burnishing process starts with the application of a coarse 400-grit diamond pad which is applied using a rotary floor scrubber and lubricated with water. This pad is run over each tile two to three times and this effectively cleans the stone removing any old sealer in the process.

After rinsing the fine slurry off the floor with more water and extracting with a wet vacuum I turned my attention to the grout. For this I applied a strong dilution of Tile Doctor Pro-Clean along the grout lines and scrubbed it into grout with a stiff brush. The cleaner was then rinsed away with water taking the dirt with it and extracted as before using the wet vacuum.

I then continued to burnish and hone the Marble tiles starting with 800-grit pad and then followed by 1500-grit pad. Each pad was applied with water to lubricate and then the slurry rinsed and extracted off the floor as before. The floor was then left to dry out overnight.

Sealing a Tumbled Marble Tiled Kitchen/ Dining room Floor

On day two I returned and began work by checking the floor was dry enough to seal with a damp meter. All was well so I proceeded to apply the sealer. After discussing sealer options with the client, I opted to use Tile Doctor Colour Grow which is a colour intensifying sealer which enhances the natural colours in the stone. It also provides durable protection by impregnating the pores of the stone preventing dirt from becoming engrained there. I applied two coats of Colour Grow allowing time in-between for the first coat to dry before applying the second.

Before leaving for the day I buffed the floor with a white pad to remove any excess sealer and give the floor a lovely sheen.

After I had finished the floor looked pristine and my client was over the moon.
