"Lane and his team were great to work with. After a quick site inspection of my driveway, I received a competitive quote for crack repair and seal coating, next day. Thunderstorms caused the cancellation of our initial work day, but Lane quickly got me back on the schedule. My driveway was a year or two overdue for repair, but LB Asphalt & Construction has it looking new again. I?ll be calling Lane for future work without hesitation."

Driveway Sealcoating questions, answered by experts

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.

In general, water-based driveway sealers are considered the most eco-friendly option. Products that utilize water, limestone, and some basic binding agents have lower VOC levels and odor levels compared to sealants made with oil or tar. In recent years, soy-based driveway sealers have become available for homeowners who want fully VOC-free driveway sealers.

When asphalt cures, it typically changes from a very dark black hue to a lighter, more matte gray color. Cured asphalt also won’t be tacky or sticky to the touch or emit any odors from the asphalt mix. Additionally, the surface of fully cured asphalt won’t deform under any pressure.

Most sealing projects take 1-2 days, including drying time before allowing traffic.

A good rule for all homeowners is to seal every driveway to protect it. Wait at least three months to seal an asphalt driveway and one month to seal a concrete driveway. You know it’s time to reseal your driveway when it shows obvious signs of wear and tear. It may appear as fading or discolored asphalt, small cracks, and oil stains. If you notice that one area of your driveway seems to dry slower than others, it’s time to reseal.
