Tips:
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.
