After noticing several areas on your driveway that tiny cracks in the surface, you may decide to try to fill in these alligator cracks yourself. If so, use the following three tips to help you fill in the alligator cracks in your home's asphalt driveway.
Clean Out the Dust with a Whisk Broom
Before you start filling in the alligator cracks, the first thing you should do is make sure that the cracks are as free from dust and debris as possible. Making sure there are as little free particles as possible within the crack helps create a more solid foundation to which the filler can attach.
To ensure that you reach the bottom of the cracks, use a whisk broom to sweep inside and around the cracks. Make sure you choose one with very stiff bristles so that they can penetrate the tiny spaces left by the alligator cracks.
Use an Asphalt Squeegee to Smooth Out the Surface
Once you are ready to start filling in the alligator cracks with an asphalt filler, have an asphalt squeegee on hand for after to apply the filler. This squeegee is designed to remove the excess patching material so that you have a smoother surface once the filler has set up.
When filling in the cracks, do small sections at a time, starting at one end of each crack. As you fill in the spaces, run the squeegee over them. Each time you finish filling an area, start the squeegee a few inches past your ending point to ensure there are no spaces or gaps left in the filler.
Apply a Spray Sealant Coating
After you have filled in the cracks and allowed the filler to set up for a couple of days, you want to finish the job by spraying a sealant coating over the patched areas. If a sealcoating is not applied, the asphalt patch will be exposed to moisture, pressure, and temperature changes, leaving it vulnerable to damage.
Using the instructions on the can, spray the sealant over the cracks and a few inches on either side. However, if your driveway has never had sealcoating applied, you may want to speak with an asphalt contractor to see about having the entire surface covered.
Using the tips above can help you fill in your driveway's alligator cracks while giving the surface a long-lasting, smooth finish. However, if you find that you have more damage to your driveway than the small cracks, you may want to contact a contractor, such as from Stripe A Lot, who specializes in asphalt crack repair to have them inspect the damage and recommend your next course of action.
