"Javier at TN Construction was amazing! As project manager (and worker) he was thorough, professional, knowledgeable, and a great guy to work with. He listened carefully to my questions and proposals for what we wanted done, then followed through precisely. He was quick to respond to texts. And, most shockingly of all in my experience with contractors, his crew was at our house, prepared, with everything they needed, exactly when he said they would be! They went the extra mile to please us and they certainly did! I feel confident that Javier and his crew would go that extra mile for all their clients."

Driveway Sealcoating questions, answered by experts

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.

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.

You should plan on sealing your driveway about once every five years, although you should plan to do it once every three years if your area experiences frequent rain or snow. Sealing your driveway protects it from moisture, UV rays, and chemicals from your car, like motor oil and antifreeze. If you find that your driveway stains easily or appears to be cracking or fading, you may want to schedule a sealing service regardless of when you last sealed it.

To maintain their strength, asphalt driveways and parking lots need to be sealcoated once every two to five years. You may also need to reapply paint striping every few years as it fades to ensure drivers can safely navigate the parking lot.

Regular sealing, drainage management, and debris removal help prevent asphalt deterioration, protecting and extending surface life.
