Repairing Concrete Cracks Instructions

  • Repairing Concrete Cracks

    Cracks in concrete form due to the freezing and thawing of water that has seeped under the driveway, weed or grass growth in small cracks, and general wear and tear. Regular maintenance will prevent the need to replace the existing driveway. This is usually easy to do and requires up to a half day to complete depending on the condition and size of your repairs.

  • Overview

    The first step to any concrete repair is to clean the area. Next, determine the size of your crack. The directions for repairing cracks less than ¼”, ¼“ to ½” and areas greater than ½” will differ.

  • Preparing the Area

    Clean the crack by removing all loose dirt and chunks of concrete with an awl or hook. If there are larger chunks of concrete you can use a mallet and chisel to loosen them. Make sure to wear eye protection. Use a broom or a stiff brush to remove small pieces of concrete and dirt. Then, using the spray attachment on your garden hose, spray the crack with water to remove any remaining debris. It is important to clean the crack well so that the patching material will adhere to it. If there is oil in the crack, use detergent to scrub it out and then rinse the crack thoroughly. Allow all surfaces to dry before continuing with the patching process.

  • Cracks under 1/4”

    Cracks that are less than ¼” are generally filled with sealants that come in a caulk gun tube. Squeeze the filler into the crack until it begins to overflow. Then smooth it out using a metal or plastic scraper. As the filler dries, it may not completely fill the crack. In this case fill the crack and smooth it out again.

  • Cracks between 1/4” – 1/2”

    Fill cracks that are between ¼” and ½” with pre-mixed mortar or a sealant that comes in a can or plastic jug. Shake or stir the product well before using. Pour the filler into the crack until it begins to overflow and smooth it out using a metal or plastic scraper. Again, pay attention that the sealant completely fills the crack even after it has dried and repeat if necessary.

  • Cracks over 1/2”

    Cracks that are larger than ½” must be filled with pre-mixed concrete. Mix your material as the manufacturer recommends, and pour the concrete mixture into the crack. Wait an hour before removing any excess concrete.

  • Curing the Patch

    Drying may take several days. Keep the patch moist by lightly misting the area using a garden hose and keeping it covered with a plastic sheet, as slowly curing the concrete will give you a stronger patch. When the concrete has cured, apply a commercially available water seal with either a roller or a sprayer.
