Repair A Small Crack In A Concrete Sidewalk And Seal Its Surface

If a small portion of the concrete sidewalk in front of your home has a crack in it, due to excess weight being placed upon it, remove loose fragments of concrete and patch the damaged section with the steps below. After completing the project, apply a coat of concrete sealer to the sidewalk to provide the paved surface with a uniform appearance and prevent moisture from damaging the concrete.

Materials Needed

  • push broom with stiff bristles
  • wire brush
  • putty knife
  • shop vacuum cleaner with hose
  • concrete cleaning agent
  • waterhose
  • bucket
  • sponge mop
  • cold concrete patch
  • trowel
  • drop cloths
  • concrete sealer
  • roller and roller frame
  • extension handle
  • paint tray

Sweep The Sidewalk's Surface And Remove Loose Concrete

Use a push broom that has stiff bristles to sweep the sidewalk's surface. If there are loose pieces of concrete stuck inside the damaged portion of the sidewalk, move a wire brush over the crack to dislodge them. The tip of a putty knife can also be used to help pull pieces from the gap. Use a shop vacuum cleaner's hose to suck up tiny pieces of concrete.

Clean The Concrete And Fill The Crack

Add a concrete cleaning agent to a bucket and add the recommended amount of water to the agent as specified on the back of the product's packaging. Dip a sponge mop into the cleaning mixture and move the cleaning tool over any dirty spots on the sidewalk's surface. Rinse the sidewalk off with a strong stream of water and wait for the concrete surface to dry.

Apply an even amount of cold concrete patch to the tip of a trowel. Many types of patch are premixed and do not require that any additional items are added to them. Insert the trowel into the crack to fill it with the patch. Use a putty knife to level the patch with the rest of the sidewalk's surface. Wait for the patch to cure.

Apply A Coat Of Concrete Sealer

Cover the portions of the ground that are adjacent to the sidewalk with drop cloths. Pour some concrete sealer into a tray that is designed to hold paint. Dip a paint roller into the sealer and push the roller across the sidewalk's surface in straight lines. Wait for the sealer to dry completely and add a second coat if you didn't effectively cover the concrete with the first coat. Once the sealer has dried, use the sidewalk as you normally would.
