Vertical concrete repair with Roadware 10 Minute Concrete Mender™ is simple if you use a few basic techniques. The following is a repair to a spalled out concrete step. As with any concrete repair, the first step is to remove any loose concrete with a chisel and clean the repair area with a wire brush and a shop vacuum. Remove all dust, dirt and loose materials. Any moisture on the concrete surfaces should be allowed to dry. On occasion, I will use a heat gun to dry the concrete.
