Best driveway sealcoating pros near Exeter, NE

New asphalt goes through two stages: drying and curing. Drying typically takes 24 to 72 hours, after which the surface is solid enough for light use like walking or careful driving. While you may be able to park on it after 72 hours, the surface is still soft and should be treated gently. Full curing is a much longer process, taking anywhere from 30 days to a full year for the asphalt to reach maximum strength. During this extended curing period, the asphalt is susceptible to damage from heavy vehicles, sharp objects, and high temperatures. Factors like weather, the specific asphalt mix, and application thickness all influence drying and curing times. For the most accurate timeline and to ensure the longevity of your new asphalt, it is always best to consult with your installation contractor for their specific recommendations.

No. You cannot use asphalt products on concrete driveways. To seal a concrete driveway, use acrylic, epoxy, polyurethane, silane, siloxane, and silicate sealers or deep penetration sealers made specifically for concrete. Meanwhile, asphalt sealers contain refined coal tar (asphalt emulsion), water, sand, clay, polymers, and additives and are incompatible with concrete’s surface texture and higher density.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

If your asphalt driveway shows cracks, potholes, or standing water, it’s likely time for a repair. Cracks, big or small, let water seep in, weakening the base and causing further damage. Potholes are a sign of this weakening process in action while standing water suggests your driveway has poor drainage, which can cause even more issues. You may also see warping or buckling—a sign of a compromised base layer—or sinking pavement. Spotting these signs early on can help you save yourself a bigger repair bill in the future.
