You’ve probably seen decorative joints in concrete before, from faux paving stones to circular medallions. You may have even wondered how they’re made. After all, saw blades only cut in straight lines, right?
According to Bob Harris of the Decorative Concrete Institute, not really.
Harris shows you how to cut both round joints and precise straight joints with walk-behind saws and angle grinders in this ConcreteNetwork.com video. (You may remember him from another ConcreteNetwork.com video that we featured two weeks ago on cutting control joints in concrete). Since this is a video about decorative concrete, there’s also a section on dyeing and acid staining. Watch it now, and let us know what you think in the comments section.
