Driveway Sealcoating questions, answered by experts

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.

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.

Asphalt dries and cures best between 50 and 85 degrees Fahrenheit. This range allows moisture to evaporate quickly without causing the asphalt to cool too fast, which can negatively affect the drying process. However, keep in mind that other weather conditions can also affect curing and drying times, such as precipitation and humidity.

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.

The main difference between asphalt and blacktop is that asphalt has a lower ratio of bitumen—a low-grade tar-like crude oil—than blacktop. While blacktop is heated to 300 degrees or more, hot-mix asphalt is heated to a lower temperature, typically between 275 and 300 degrees Fahrenheit. Consult an asphalt driveway professional about which type of material is the best fit for your future asphalt driveway.
