Driveway Sealcoating FAQs, answered by experts

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.

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.

Ideally, you should seal your driveway when there won’t be rain for several days, but at a minimum, there can’t be rain for at least 24 hours. If it rains shortly after you seal your driveway, the water can wash away the sealer and render your work useless. You’ll have to wait for your driveway to dry out and try applying again. Note that some sealers—like oil-based sealers or specialty fast-drying sealers—may cure faster. Ask your contractor for information on timing before the install, and if there’s rain in the forecast, postpone the job.

Costs depend on the extent of damage, material costs, labor, and whether resurfacing is needed.

Regular maintenance will help you avoid costly repairs and early replacement. Clean the driveway surface with a stiff brush and water at least twice yearly, and remove any weeds that try to take root. Additionally, every two to five years, apply a sealcoat—this protects the driveway against damaging UV rays and keeps it looking like new.
