2. Consider the bond strength. If you want the abrasives on your concrete grinding wheel to cut efficiently, then the wheel must contain the proper bond. The bond is the material that holds the abrasives in place to enable them to cut more effectively. The bond should also wear alongside the abrasive grains, as it will expose sharper grains.

To grind, hone and polish a concrete surface to the maximum "clarity of reflection," use a sequence of grit abrasives, moving on to the next finer grit only when the previous one has done its job. This will insure a clean, crisp look of the concrete surface at a 200-, 400- and 800-grit resin while achieving a maximum surface durability.
