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.
Use Roadware MatchCrete™ Clear, quartz sand, and portland cement to repair cracks in exterior concrete sidewalks and decks with a broom finish. MatchCrete™ Clear is a non-yellowing polyurethane bland that sets fast, bonds very well and can accommodate exterior conditions.
A common concrete repair problem is broken steps. Roadware 10 Minute Concrete Mender™ is a good choice for repairing steps and curbs. Here is a repair sent in by Roadware distributor Minitman Supply in Colorado.
Rebuild of a Damaged Step Corner
A repair like this one starts with cleaning the concrete with a wire brush or diamond blade. Use blue Dow board to make a form and hold it in place with duct tape.
Fill the repair area with Roadware 10 Minute Concrete Mender™ combined with silica sand. Pull the form after the material sets in about 10 – 20 minutes depending on temperature.
After you remove the forms, you will see something like this.
Use a finishing stone to bland and contour the repair into the rest of the steps. A finish coat of a latex cement finishing coat over the entire stairway will have your steps looking good as new.
