Polished Black Marble Foor Polished in Barrow in Furness
This client from Barrow in Furness contacted Tile Doctor about their polished black marble floor which had been installed 20 years ago. Its polished appearance had diminished with use over that time, and they had wasted money on different products sourced from DIY shops and the internet to rectify it.
Many of these products were unsuitable for this type of tile and as such the top surface was quite tacky to walk on and had done nothing to improve its appearance. Happy I could resolve the problem they accepted my quote to re-polish the floor and a date was agreed to commence the work.
Cleaning a Polished Black Marble Dining Room
My first task was to protect the woodwork by applying a bead of clear waterproof mastic between the wood and the floor, this prevents water being soaked into the wood through capillary action, this can cause water staining and worst-case blow MDF skirting and doors.
Once done work started on polishing the marble floor using a 200-grit 17-inch diamond pad fitted to a rotary floor machine. This pad removes encrusted sealers, old polish and other products that were upsetting the stone finish. Applied with water for lubrication this pad does a good job of cleaning up the stone but leaves it looking dull with a matt finish.
To bring back the finish, finer grit diamond Burnishing pads are applied in sequence starting with 400 then 800 and 1500-grit. These pads clean and rebuild the polish on the Marble slowly brings the stone back to life again. The floor is rinsed off with water after each pad and the soiling extracted with a wet vacuum. The edges were then completed with a small handheld machine using smaller pads of the same grits.
After this work, I started on the grout lines which were scrubbed by hand using Tile Doctor Pro-Clean which is an alkaline cleaner and will not upset the marble. I find it best to do this work by hand as the pads can struggle to reach into the recesses of the grout line.

A final rinse with clean water which was then extracted with the wet vacuum and the floor left to dry off overnight.
I called back the next day and started work by checking the stone and grout was nice and dry and ready for a final polish using a 3000-grit diamond pad. This pad brings up the polish on the floor even further and is applied using a tiny amount of water from a spray bottle which aids in the final polish.
Sealing a Polished Black Marble Dining Room
Once the whole floor was polished including all the corners and edges it was time to start applying the sealer. With this being a Black Marble floor with more than a few marks on it from the wear and tear over the last twenty years, I opted to use a sealer normally designed for outside areas called Tile Doctor X-Tra Seal. This is an oil based breathable sealer that soaks into the pores of the stone protecting it from within and ensuring any dirt remains on the surface.
We don’t normally recommend X-Tra Seal for polished surfaces as the oil takes a lot to cloth off, however in this case I felt the extra work would be justified as the oil works well on Black stone.
Once done the Marble tiles were transformed by the work much to the relief of the owner who had really struggled to maintain the floor. Before leaving I made sure to spend time discussing future cleaning and recommended, they use Tile Doctor Stone Soap going forward. This is a mild but effective cleaner which helps maintain the patina on the Marble.
