Grinding marble doesn’t have to be a complete mystery. When you’re talking about the best commercial floor surfaces, you may have invested in marble, at least for some portion of the floor’s surface.
At various times and with excessive use, grinding the marble will likely be necessary. This helps to remove scratches that develop over time through the natural process of people walking across it, dragging rolling carts and other items. It may also be necessary if the marble has uneven tiles, fractures, or deep cracks and holes.
Here are some tips that can help.
Clean the surface. Before doing any grinding of the marble surface, you want to make sure it is clean. If it’s not, the dirt or other residue that’s on the surface of the marble can cause extra damage to the rest of the marble.
The last thing you want to use when grinding marble or trying to clean it is to use what’s known as a stripping agent. These cleaners can actually degrade the marble so that when you start grinding it will begin tearing apart more and more of it.
Remove lippage. Where the tiles meet and where you have a grout line, it may not be even. It might look like it, but if you feel a rough surface, almost like an edge, you’ll want to use a grinder to help even out those seams.
Repair cracks. Before you do any grinding or sanding of a marble surface, make sure you fill in small cracks. If you set about grinding the marble surface before repairing those cracks, you will notice chipping and holes beginning to develop.
Diamond polishing. When you have completely sanded or grinded down the marble surface to your specifications, you want to use a diamond grinding tool to create a fine surface. This will help create a more polished and finished look to the marble surface.
