As you grind concrete the diamonds cut into it and scratch it away. During this process, the diamonds break and wear down, but at the same time, the bond metal is worn away by the sands of the concrete which allows more diamonds to be exposed so that cutting can continue. When you grind concrete that is too hard for the bond (matrix) the ...

Polished concrete is the highest category of steps of processed concrete. Any grit abrasive from approximately an 800-grit resin and above, typically to a 1,500 or 3,000 grit, is considered a polishing step. A polished concrete surface has clarity of reflection like a mirror and has a glass-like finish.
