Repairing chipped concrete steps can be a tricky task, but it is possible to do it yourself with the right materials and tools. Start by cleaning the area of all debris, dirt, dust and moss. Then, apply a layer of concrete patch with a mason's trowel. For structural damage, fill the holes and smooth the surface with a trowel.
Coat the inside of the mold with cooking oil spray and apply a plentiful layer of latex adhesive liquid on the chipped surface. In a plastic bucket, mix a small batch of quick-setting cement, such as Quikrete's FastSet cement. Pick up some of the cement with a pointed trowel and press it firmly into the shape. Lightly fill the corner, then smooth the cement flush with the top of the step.
Allow the repair to dry overnight before carefully peeling off the tape and removing the mold. Spray the damaged area with water from your spray bottle, just enough for a ready mist. Using the trowel, apply the wet cement to the broken parts of the cement steps. Make sure you really work in every nook and crack.
You can also use Cement All and NewCrete together for a team remedy for any concrete installation problems. To make the new concrete match the old one, hammer some of the original pieces that fell off until a fine powder is left and sprinkle over the patch while it is still wet and level carefully. Finally, you may want to re-coat all steps with a concrete resurfacing for a consistent look.
