DIY steps
- Before starting, put on protective gear, including gloves, safety glasses, and a dust mask. Clear the area around the crack of any debris, toys, or obstructions. If the crack is deep or wide, consider using a backer rod to provide additional support and help the filler adhere.
- Use a wire brush to scrub the crack and surrounding area, removing any dirt, oil, or other substances that might interfere with the filler's adhesion. This will help ensure a strong bond between the filler and the driveway.
- Cut the nozzle of the caulk tube at an angle to create a 1/4-inch opening. This will give you more control over the flow of filler and help you fill the crack more accurately.
- Use the caulk gun to fill the crack, starting at one end and working your way down. Hold the nozzle close to the surface and squeeze the gun gently, using a steady, consistent motion to fill the crack completely.
- Use a putty knife to smooth out the filler, feathering it out towards the edges so it blends in with the surrounding surface. Make sure to fill the crack completely, but avoid overfilling, which can create a mess.
- Allow the filler to dry completely, according to the manufacturer's instructions, before sealing the driveway or exposing it to water. This will help the filler cure properly and ensure a long-lasting repair.
- Once the filler is dry, use a wire brush to remove any excess material and smooth out the surface. Your driveway is now ready for sealing or use.
