"Fortunately, this company wasn't the normal seal of your driveway and run. This company removed any high spots, bumps, low spots, covered everything with a fresh surface of new asphalt and they ran roller machines over it for some hours. It looks great."

Driveway Sealcoating questions, answered by experts

Many services include sealing as part of the repair process. Confirm with your contractor.

New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.

During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.

The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.

It extends pavement life, improves appearance, protects against weather, and reduces maintenance costs.

Regular cleaning, sealing, and timely repair of cracks help maintain its condition.

You don't technically need to seal your driveway after pressure washing, but doing so will help keep your driveway clean for longer. The best driveway sealer depends on the type of driveway you have. To seal asphalt, consider an asphalt emulsion sealer, fast-drying sealer, or latex acrylic sealer. Concrete driveways commonly use acrylic sealers or penetrating sealers.
