Repair A Concrete Sidewalk That Has A Long Crack In Its Surface

Blog

If a piece of heavy equipment accidentally fell onto the concrete sidewalk in front of the business that you own and has formed a long crack in its surface, successfully patch the damaged area and improve the appearance of the walkway by completing the following instructions.

Materials Needed

  • broom
  • dustpan
  • shop vacuum (with hose attachment)
  • water hose
  • commercial-strength cleaner for concrete
  • long-handled scrub brush
  • degreasing agent
  • container of concrete patch compound
  • handheld shovel
  • trowel
  • tamping tool
  • bucket of sealant (designed for concrete)
  • mixing stick
  • paint roller
  • signs

Remove Loose Concrete And Clean The Sidewalk's Surface

Sweep up loose concrete pieces. If there are small pieces that are stuck inside of the crack, a shop vacuum cleaner's hose can be used to collect them. Use a water hose to moisten the sidewalk's surface. Remove visible stains on the concrete with a commercial-strength cleaner that is designed for concrete and a scrub brush. If there are any grease spots on the sidewalk's surface, eliminate them with a degreasing agent. Remove the cleaning agent and degreasing agent with a water hose once the sidewalk's surface is clean.

Use Concrete Patch Compound To Fill The Crack

Apply concrete patch compound to the crack with a small shovel or trowel. Make sure that the compound is firmly packed into the damaged section. Use a tamping tool to flatten out the surface of the patch. Wait for the patch to cure. This may take several hours, but it is best to read the back of the compound's container to determine how long you may need to wait since some brands of compound may take longer than others.

Apply Concrete Sealant To The Sidewalk

Eliminate air bubbles from a container of concrete sealant by stirring the product for a couple minutes. Apply a thin, even coat of sealant to the sidewalk's surface with a paint roller. Move the roller along the sidewalk in straight lines. Apply more sealant to the roller as needed. 

While you are waiting for the sealant to dry, post a sign next to each end of the sidewalk so that nobody walks upon its surface while it is still wet. After the sealant has dried, add an additional coat to the concrete if you missed any spots when the first one was applied. Once dry, the sidewalk can be walked upon as normal and you will no longer see any signs of damage.

Decorating Your Pavement

After I began working with a friend of mine to beautify my yard, I realized that there was one piece of the puzzle that I seemed to be missing. My driveway and front sidewalk were in dire disrepair, and I knew that I needed to do something to make things right. I worked with a paving contractor to completely patch, refinish, and stain the pavement, and when he was done the area blended right into my design aesthetic. This blog is all about decorating your pavement by doing things like using concrete acid stain and hiring professionals to add decorative details.
