Mar 29, 2019 · Use a straightedge or snap line to lightly mark the joints before cutting and keep your tool straight as you cut. A grooving tool works well for most projects. If your concrete has already started to dry and crack, use a dry-cut saw that can cut to the desired depth. For extra large projects, use a long-handled marking tool.
In addition to the concrete mix and the weather conditions, determining when to saw concrete is based on the concrete's hardness as well as the type of cutting equipment used to make the saw cuts. Cutting too early causes raveling, an effect created by the saw blade pulling the aggregate out of position, leaving a messy, weakened edge along the cut.Get Price
