Natural stone floors, especially in a high-traffic commercial areas become dull and lose their shine when the sediment and grit (sand that people bring with their shoes) start eroding the stone’s crystals.
The foot pressure forces the sediment lying on the surface, causing an abrasion and fracturing the delicate crystals of the stone. The only safe and proper way to restore the crystals natural ability to reflect light evenly and provide a brilliant shine is to re-hone & re-polish them by using diamond abrasives, engineered and designed particularly for Granite and/or Marble works.
Specific types of diamond super-abrasive discs are used through the various stages of the floor restoration process. Metal bond diamond discs are used for rough grinding, heavy stock removal, leveling and flattening the floor.
Electroplated diamond discs are used on Marble & Terrazzo. Sintered and brazed diamond discs are used on Concrete, Granite and Marble. Rigid resinous diamond discs are used to grind, hone and polish the floor surface.
Most natural stones are composed of minerals that vary by hardness to one another. Using diamond discs that flex and float (designed for edge polishing applications) cause an uneven polish. Flexible diamond polishing pads and/or discs have the tendency to remove more of the softer portion of the stone, causing a ‘wavy’ appearance and uneven reflection on the surface.
Resinous diamond discs with different diamond properties and bonding agents are used on Granite and Marble applications.
Mechanical diamond polishing is a very orderly, multi-step process.If there are any high-low areas present (commonly known as lippage) the floor should be ground flat using the metal bonded diamond discs.
It is very important to make sure that all prior scratches are removed before moving onto the next grit step.
Each diamond grit step requires an average of 4 passes, depending on the density of the particular stone and its current condition.
If the floor is worn and scratched, begin with the metal bonded diamond super abrasives.
Once the floor is leveled, continue with the resinous diamond discs and begin with a grit size equal to the one of the metal bonded diamond discs that you’ve just completed or a step lower. That will ensure there won’t be any scratches and swirl marks left from the previously used metal bond diamond super abrasives.
Rinse the surface well in between every grit in order to remove all of the excess material remains.
Once the grinding stage is entirely completed, continue through the honing diamond steps. Many Marble stones and Terrazzo are capable of taking a polish immediately after completing Grit 400.
However, Granite, green Marble (Serpentine) and some other Marble stones require higher honing steps, prior to the polishing.
After the last honing step is completed the stone’s crystals will begin developing a low shine and will be capable of taking a higher polish and developing a reflection.

Testimonials
I wanted to thank you for the restoration work you and your crew completed in our building. The marble entries and bathrooms look wonderful! All of us have been thrilled with the results of your work, even agreeing the stone looks better now than when it was installed.
Angelo and Sergio were pleasures to work with day in and day out. They were proud to show our staff their procedures to polish the marble. I hope they enjoyed their time here, as it was quite a chore to get through all 158 rooms. It is always exciting to find another organization that recognizes the importance of excellence. We are glad to have started a relationship with Marble Doctors, and look forward to more projects and shiny marble!"
