Should I Sealcoat my driveway? Benefits of Asphalt Sealcoating

Updated: May 29, 2020

Did you know that in only a few hours, a faded, dull asphalt pavement surface could be restored, almost like new? The magic of sealcoating is real; it not only restores your driveway cosmetically, but prevents against the premature breakdown of the asphalt as well.

So what exactly is asphalt sealcoating?

Sealcoating is the process of applying a thin liquid layer over a paved surface to protect it from damage caused by UV rays, rain and snow, and fluids from vehicles. Sealcoating won’t cure existing issues, like cracks, but it will help prevent such damage from forming in the first place. Sealcoating the asphalt, seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material; improving the longevity of your driveway or parking lot.

What are the benefits of sealcoating?

  1. Sealcoating protects and prolongs the life expectancy of asphalt pavement by filling surface damage and providing a protective layer to keep out damaging UV rays, vehicle fluids, and water.

  2. The low cost of regular sealcoating can save you money in the long run. A properly maintained and sealed asphalt surface has an extended lifetime and reduces long-term repair costs.

  3. With exposure to the elements, asphalt pavement over time becomes faded in appearance. A fresh sealcoat application enhances the appearance of asphalt, making it look and wear like new.

  4. Sealcoating acts as a waterproofing agent, minimizing the rate at which water enters the asphalt. Sealcoating asphalt prevents the seepage of water and moisture from rain and snow, thus preventing damage from freeze thaw cycles which is a common reason driveways or parking lots begin forming cracks.

  5. Sealcoating seals the asphalt pavement, preventing the oxidation and erosion of the top layer; along with replacing fine particles lost from the asphalt surface due to oxidation on older pavements. It also resists gas, diesel fuel, oil, salt, and chemical penetration which will break down the bond between the aggregate and the liquid asphalt.
