Maintaining and repairing your asphalt parking or driveway surface is important for keeping a long-lasting asphalt surface. As time passes, sun, weather, and vehicle traffic can cause your asphalt's durable surface to degrade, break down, become faded, and ultimately fail. Take action and repair cracks and other damage when they first begin to show and whenever you plan to resurface with seal coat or new asphalt. Here are two steps to help you properly repair damage and prepare your asphalt for resurfacing.
Step 1: Clean the Surface
Before you can seal coat or repave your asphalt surface, it is important to clean and prepare the surface to receive a new layer of asphalt. The new layer of asphalt or seal coat protects and resurfaces the old asphalt to help the surface last several more years.
First, remove vegetation that may be growing through any cracks or gaps in the asphalt. Use the tip of a screwdriver, the blade of a shovel or garden trowel, or vegetation clippers to dig up and remove all traces of vegetation.
Next, it is important to remove any sediment, rocks, silt, or other materials that have settled onto the surface or in any cracks in your asphalt. Lift out any large chunks of damaged asphalt from any cracks or larger potholes that you will be repairing.
Use a pressure washer or a shop vacuum for smaller areas to remove any dirt and debris, especially from within cracks on the asphalt. If you use a pressure washer to clean dirt and debris from the asphalt, be sure to allow the pavement to thoroughly dry before applying the new layer of asphalt or seal coat.
Step 2: Fill Cracks and Holes
After your asphalt is cleaned and free of vegetation, you can apply the crack filler to fill any cracks in its surface. If any cracks are left un-repaired, they can grow larger to become a bigger problem.
Buy a tube of asphalt crack filler to fill in any smaller and hairline cracks, applying the filler into the crack with the tube's tip. For larger cracks, fill them with a tube of asphalt filler caulk, which is a thicker type of repair product. Be sure to press and apply the caulk into the base of each crack, filling it to its top until the repair is flush with the surrounding surfaces.
If you have wider cracks that you can fit one or two of your fingers into, you can begin their repair with foam backer rod. Press a length of foam backer rod deep into the crack, and then apply asphalt repair caulk around and over the rod, covering it within the crack.
Follow all product's instructions to allow for drying time. Don't drive or walk over the repairs until they have fully set and dried.
