Concrete driveways are a durable and long-lasting surface, but they can still develop cracks over time. Fortunately, there are several steps you can take to repair cracks in a concrete driveway. First, use a screwdriver and wire brush to remove any residue from the crack. Then, use a pressure washer to wet the driveway and add a Quikrete engraver, cleaner, and degreaser to the machine tank.
Attach a high-pressure nozzle and thoroughly clean the surface. Next, mix Re-Cap Quikrete Concrete Grinder with water in a 5-gallon bucket and pour it over the cracks. Use a flat-edged trowel to force the mixture deep into them and allow it to dry overnight. Finally, mix a much thinner batch of rejuvenator and moisten the concrete before applying it.
For larger jobs, you may need to use a hammer and mason's chisel to chip away any soft or crumbled concrete in and around the cracks. Additionally, use a weed removal tool or lawn edger to scrape away any grass or weeds that may be in crevices in the driveway surface. Finally, seal the area with an advanced polymer concrete crack sealant for added protection.
