Grit and Bond Needed
Do you need to remove mastic or some other tough material, or is this a simple polishing job? Concrete grinding discs come with different levels of grit according to the type of job.
Higher number labels on grits mean that the disc is less aggressive to the concrete surface. These grit levels are best for polishing after the hard work has been done. A typical label for a concrete grinding wheel meant to polish is 80 or 100.
More aggressive grits are meant to remove coatings like epoxy and mastic or grind down harder concrete. For tough jobs, you can try an 18 or 20 grit. For moderate jobs, you can resort to a 30 or 40 grit.
Grit isn't the only thing to pay attention to. The hardness of concrete can wear down your tools if you're not using the right kind.
Newer concrete tends to be harder while older concrete tends to be softer. If you're dealing with newer concrete, you'll want to make sure your tool is equipped with the right bond.
The bond is the level of wear resistance. You'll want a soft bond for harder concrete floors so that new diamonds are released quickly to keep grinding down the concrete. For softer concrete, you'll want a hard bond.
