You can also use concrete grinders to polish the surface of the concrete, making it look brand new. ... When grinding topical concrete, use silicon carbonite wheels; for general grinding purposes, use diamond wheels. The most important factor is achieving complete surface contact with the grinding wheels for seamless, smooth concrete.
Yes, a concrete grinder can be expensive, especially the best concrete grinder, but it's well-worth the cost in the end. Although there are many different names for concrete grinder, including concrete planers, scarifiers, milling machines, surface planers, etc., they all perform the same function.
