5 Common Sealcoating Questions: Answered

If you’re planning on sealcoating pavement, it’s important you understand the process. Whether it’s brand-new or recycled asphalt, the sealcoating procedure will remain the same. In fact, according to the National Asphalt Pavement Association, “More than 99% of asphalt pavement reclaimed from roads and parking lots was reclaimed for use in new pavements instead of going into landfills.” This means the chances are high that the driveway or parking lot you are sealcoating contains recycled material. As such, they’ll require protection.

At NAC Supply, we offer more than sealcoat supplies—we have the industry knowledge to answer all your sealcoating questions. Our team of experts will make sure you get what you need for every job, no matter the scope of work. Below we answer some of the more common sealcoating questions.

How long should I stay off the asphalt after sealcoating?

The drying and curing time of sealer depends on the humidity level, temperature, and how much sunlight there is. The ideal weather conditions include low humidity, high temperatures, and lots of sunlight—this will speed up the process. Under these perfect conditions, we recommend staying off the pavement for a minimum of 24 hours. As such, you should plan to not be able to use the space for a few days depending on the environment.

What is the best time of year to sealcoat?

The single most important factor in deciding when to start a sealcoating project is the weather. The ideal temperature is 70 degrees and rising, meaning you want to perform this task early on so it gets warmer as the day goes on. Never start a project if it might or has recently rained. Water will keep the coating from adhering and drying properly. You want plenty of sunshine to speed up the drying.

What does sealcoating do?

Since asphalt receives regular exposure to the elements, it needs some protection. That’s what sealcoating does—it provides an extra layer of protection to the asphalt. This protective coating prevents water, oil, and UV rays from damaging the asphalt. Regular sealcoating will extend the life of the asphalt and decrease the odds of needing a replacement early on.

How often should I sealcoat?

The general rule is every other year, but that is only a guideline. There are a lot of factors that you should note when making this decision. If there are a lot of heavy-duty vehicles, high traffic, and scraping from snowplows, you may need to sealcoat more often. The damage that occurs to a lot or driveway will determine how often it needs protection.

How should I prepare?

There are a few precautions you’ll want to take before sealcoating. The following actions will ensure your asphalt receives the proper protection:

  • Don’t mow the grass during or immediately after professionals apply the sealcoat. You don’t want grass clippings to get stuck in the wet sealer. Additionally, if you regularly apply fertilizer to any grass along the parking lot or driveway, make sure to do this a week before the sealcoating process occurs.
  • The pavement needs to be completely dry for sealcoating, so do not hose it off right before or after professionals complete the process. Make sure to turn off any sprinklers—if they start up and wet the pavement, you’ll have to stop the project and delay it until the pavement dries.
  • Avoid parking any vehicles on the pavement—it needs to be completely clear as the sealcoat dries. If you see tire marks on the pavement a couple of weeks after applying the protective coating, don’t worry. Once the sealcoat completely dries, the marks will go away.
