Driveway Sealcoating questions, 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.

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

Fading color, visible cracks, or water pooling signal the need for sealing to prevent further damage.

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.

It depends on the type of sealer. Some sealers can dry in as little as 4 hours, but many can take up to 48 hours to fully cure. To play it safe, don’t drive on your driveway for two days after sealing.
