   Once the chipped area is completely dry, you'll need a concrete-vinyl patching compound. These are available off the shelf at most big box stores and are easy to use. Simply add a small amount of water to the powdered mixture and mix it until you achieve a peanut butter-like consistency. Apply the compound to the chipped out area using a masonry trowel or a disposable trowel. Feather out the surrounding area to match the existing concrete. For corner chips or areas next to expansion joints, you may need to take a little extra time to carefully form the patch to follow the existing contours.
