Though these minor problems do not post any structural threats, it would be wise to address cracks as soon as possible through a concrete repair. Whenever chips or small cracks appear, it is certain that wear and tear would follow. Follow these instructions to repair small cracks that are 1/4 to 1/2 inch wide:

Difficulty: Easy

Time Required: One to two hours

  1. Procedure:
    Clean the crack using a wire brush. Remove loose debris and vacuum the crack. In cases where dirt, oil or grease is near or remains in the crack, remove it by a thorough cleaning.
  2. Undercut the edges of the crack by using a large hammer and a cold chisel. This process will keep the patch in place.
  3. Always use eye protection.
  4. Coat the surface of the crack with concrete bonding adhesive using a small paint brush. Let the adhesive sit and dry completely.
