Driveway Sealcoating questions, answered by experts

In general, crack fillers last for about two years on average. That timeline can be shorter if you have extremely harsh winters or longer if you live in a mild climate. Luckily, this product is pretty affordable at the hardware store (about $10 to $30) and easy to DIY, so redoing it every few years shouldn’t be too much of a hassle.

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.

The three most common types of asphalt are hot asphalt, MC cold mix, and UPM asphalt. Hot asphalt is used most often for paving and patching roadways while it’s hot and workable. MC cold mix asphalt cures more slowly than hot asphalt, but it can be used for temporary patches and repairs in low-traffic areas. UPM is also used cold, but it can be used as a longer-term fix, usable in almost any conditions at almost any temperature.

Apply either one or two coats, depending on the manufacturer’s instructions.

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