How to Grind Concrete Three Ways
Put a coarse-grit diamond grinding pad on the grinder. Adjust the rotation speed. Decide on a path and methodically move over the concrete's surface. Put on a pad with a finer grit. Completely grind the floor again. Continue to change to finer grit pads and grind the entire floor until you get the desired finish.
