Finish the Concrete
After the concrete has set for an hour or so, run an edging trowel along the inside of the forms to separate the concrete and create a finished edge (Image 1). At 4' intervals, lay a straight board across the forms and use a groove trowel to create expansion joints across the concrete walkway (Image 2). These joints allow the concrete to expand and contract and thus help eliminate cracking.
Before the concrete fully sets, lightly drag a broom across the surface to add a non-slip texture. Covering the concrete with plastic as it cures will help prevent cracking. After 48 hours, remove the plastic and the wooden forms.
