How to Fix Hairline Cracks in Concrete Driveway?
Hairline cracks in concrete driveways can be a common issue that can be easily fixed. Cracks can occur due to natural wear and tear, excessive weight and extreme temperature changes.
Hairline cracks are generally less than 1/8 of an inch in width and can be an eyesore on your driveway. Fortunately, there are several simple ways to repair hairline cracks in your concrete driveway.
The first step in fixing hairline cracks in your concrete driveway is to clean the area thoroughly. Use a stiff brush to remove any dirt, debris, or weeds that may be growing in the crack.
Once the area is clean, use a garden hose to thoroughly rinse the area. If necessary, use a pressure washer to clean the area. Once the area is washed, allow it to dry for at least 24 hours.
Once the area is dry, it’s time to repair the hairline crack. Start by purchasing a concrete patching compound and a trowel from your local hardware store.
Apply the patching compound to the crack using the trowel. Make sure to press the compound down into the crack and fill the entire void. Allow the patching compound to dry completely, which should take around 24 hours.
