What Our Customers Think of the CLC Diamond System

Prairie Supply logo"When I first learned polishing, I was taught to wet grind metal bonds dry and use the STI 50 and 100 Terrazzo Pads to transition; followed by the FL-07 series dry. This works great and I still have customers using this system.

However, for new guys getting into it; I've had great success suggesting STI’s CLC Polishing System, as it simplifies the process and removes the guesswork, while still allowing for traditional technique.”

~ Mike Nelson, Prairie Supply

logo concrete-resources"What we were pleased to find is that the diamonds worked exactly as advertised. We did not have issues with scratch marks between steps – productivity and diamond life were spot on. I will use the system again because of its predictable results and faster turnaround time (with excellent results).”

~ Darcy Manchak, Concrete Resources Inc., Edmonton, AB, Canada
