How Often Should I Reseal My Asphalt Driveway?

October 22, 2019

Asphalt driveways are durable and look nice, but they do require some maintenance to keep them that way. While you should not seal a newly installed driveway for the first six months during its curing time, it’s not uncommon for homeowners to not know when it’s time to reseal their driveways.

As a general rule of thumb, you should add new sealcoating in Des Moines, IA every one to three years, depending on the weather in your area—some areas may allow you to get by with this service only every five years. This will help guard your driveway against cracks and other types of damage that can present over time. In the case of either asphalt or concrete, repairing minor cracks as soon as possible is the best way to save yourself from costly repairs or replacements down the road.

How often you should sealcoat your asphalt driveway depends on several factors. Here are a few:

  • Quality of pavement sealer: The better the quality of your pavement sealer, the longer the sealcoat application will last. For example, durability will be compromised in a sealer composed of a low-solids material (meaning one that’s watered down). If you hire a local sealcoating company to reseal your driveway, be sure to specify that you want a quality sealer from a reputable producer.
  • Proper sealcoat and mixture application: Now that you know why the quality of pavement sealer matters, the next step is to ensure a proper sealcoat application mix design. Ideally, a properly mixed sealcoat should contain sand and maybe a polymer additive. You might be wondering why sand is used—sand creates traction for vehicles and pedestrian traffic to safely travel over, while also providing added durability to the freshly sealcoated surface.
  • Number of seal coats applied: Both resealing projects and new sealcoating in Des Moines, IA need to have two coats of sealer—yes, this double product application over your asphalt driveway is necessary to achieve optimal sealcoating results. The pros know to leave the first coat of sealer long enough to dry thoroughly before the second coat can be applied. Once the final coat of sealer is on, the driveway must be left to dry and cure for at least 24 hours before use.
  • Amount of daily traffic or use: Another factor that determines how often you should reseal an asphalt surface—and impacts the longevity of the results—is the amount of daily wear from vehicle or pedestrian traffic. Heavy traffic will result in faster sealcoat wear, while less trafficked areas deteriorate more slowly. If your driveway receives a high volume of traffic, your sealcoating technician may recommend a third coat of sealer.
  • Location: The area where you live has a role in how fast the seal coat on your driveway will wear down—think harsh winter weather that produces a lot of moisture, significant freeze-thaw cycles and the application of salt and plowing to remove snow.

The benefits of sealcoating in Des Moines, IA include fewer repairs to fix cracks and pits and lengthening the overall lifespan of your asphalt surface. Call the Pearce Paving team today to request a service estimate!
