Marble Grinding

Stone Floor GrindingMarble can be honed to a matte or satin finish through a grinding process. We can also remove severe etching and deep scratching through our natural stone Grinding service. Grinding is often needed to remove damage, and it is often used to provide a less glossy finish to the stone. Grinding can be achieved using a special grit of diamond pads that make the stone surface silky smooth while not leaving too much sheen on its finish.

Grinding is done using a special grit of diamond pads that make the stone surface silky smooth while not leaving too much sheen on its finish. Grinding your floors and countertops will give the stone a very natural look, but, you must make a special effort to clean up any spills as soon as possible to avoid damage to your honed surfaces.

Marble Restoration

At some point in time, a full marble restoration service will be required. This will be due to the large amount of cracking, deep scratching, unsightly lippage, moving tiles, grout damage, high traffic patterns, problem staining, or any other defect which cannot be remedied by polishing marble alone. Resurfacing of the marble will require a diamond abrasive procedure referred to in the industry as diamond grinding. This is carried out after any epoxy repair work. The marble is then polished or left honed and then re-sealed.

Marble Repairs

Marble can be very expensive, so buying replacement worktops, fireplaces or tiles could put a major dent in your budget. This means that rather than purchasing brand new items as a substitute for damaged ones, it’s worth considering specialist marble repairs services. Here at Njwa Marble, we have a wealth of experience when it comes to fixing items made from this material. Whether you’re in need of a marble fireplace repair, marble floor repair, or anything else, we should be able to help.

Marble Polish

This can be done with the polish process using diamond polish. Diamond polishing which is running a very fine grit diamond with water until you receive the desired polish. Then finished with polishing powders, pastes, or diamond pads. These pastes and powders are very abrasive and acidic and when used correctly they can give good results. We polish using a combination of those technologies, and techniques.

Marble Cleaning

Due to its acid sensitivity, marble must be cleaned using an alkaline cleaning solution. We give the solution approximately 20 minutes of dwell time. This gives the cleaner time to emulsify the dirt that is embedded into the stone and grout. We then use an industry-accepted spinner tool which provides pressure coupled with vacuum for extraction.

This process also removes dirt from the top of your grout lines. This is the industry recommended method to clean stone and tile floors.

Marble Maintenance

A polished marble floor will scratch very easily compared to a harder stone like granite. Sand, which has a hardness rating of 7 on Moh’s Scale will scratch marble if it walked onto as most marble has a hardness rating of about 3.
The reflectivity after polishing marble is caused by natural crystals in the stone. When sediment and grit are walked, dragged, or scraped across the stone, the crystals become damaged and the surface is no longer even, causing a loss of reflectivity and shine.
It is important to protect your marble with good barrier matting as a preventive step. Keeping indoor slippers to change into by the door is also recommended as outdoor dirt and grit can become trapped in the tread of the shoes. Taking these measures will help to prevent the loss of shine.

Marble can be extremely porous if it is honed rather than polished and so it is imperative that it is properly sealed with a penetrative sealer prior to usage. Polished marble does not necessarily need to be sealed due to something called the Beilby layer.
