How To Concrete Grinding 3 Methods 11 Steps Cost Overview
Feb 22, 2021 After grinding with the 150-grit diamond, you must apply a chemical hardener to densify the concrete surface. Now you can start the polishing. Start with a 100- or 200-grit resin-bond diamond, or a combination of the two. After that, polish with a 400-grit resin-bond diamond. Then you may proceed to also polish with an 800-grit resin-bond diamond.
