Concrete Resurfacing – Repairing Small Cracks

While small cracks don’t indicate any structural problems with concrete, it is best to fix the issue as soon as possible. Once a small cracks appears, wear and tear will inevitably cause it to expand. ‘Minor’ usually refers to cracks that are 0.5 inches or less deep and 0.25 inches or less wide. Here is a quick 5 step process to repair minor cracks and get your concrete ready for resurfacing:
  • 1. Clean the cracks with a wire brush. Get rid of loose debris and vacuum. Be sure to thoroughly remove any oil or grease around the crack.
  • 2. Use clean sand to fill up the crack; if it is more than 0.5 inches deep, only fill the crack up to 0.5 inches with sand.
  • 3. Purchase premixed concrete crack sealant, shake the container and cut its tip to the same width as the crack.
  • 4. Apply the sealant in layers of 0.25 inches and if you need to force the sealant into the crack, use a putty knife. Allow each layer to set overnight before trying to add another one.
  • 5. Do not fill the cracks beyond the surface level of the concrete. Don’t walk or drive across it until the sealant has been fully cured.
