What is Asphalt Sealcoating?

Sealed and Striped Parking Lot

Asphalt pavement is made primarily of rock and/or stone and gravel, along with a binder. The binder, also known as asphalt cement, is created from certain crude oils. Maintaining this binder is essential in prolonging the life of asphalt surfaces.

Sealcoating is a protective coating made of coal tar, along with additives specific to the climate of the project. It is applied over asphalt to protect those oils and prevent water, oil, and UV rays from damaging your parking lot. It is applied as a liquid, and dries to a deep black finish.

At National Pavement, our teams have sealed more than 10 million square yards of pavement since the 1980’s. Our asphalt sealcoating contractors meticulously apply top-of-the-line asphalt sealer to keep your lot looking fantastic and protected from the elements.

Benefits of Asphalt Sealer

Sealcoating Extends the Life of Your Asphalt
Rain Protection sealing Asphalt

One of the biggest benefits to asphalt sealing is the fact that it can double the life of your asphalt. Asphalt is a naturally porous material and rain, snow, and temperature changes cause cracks and buckling over time, while harsh sunlight fades the surface.

Sealcoating protects the asphalt by making the surface less permeable to water, chemicals, and UV rays. When the asphalt is protected, your risk of cracks and damage is greatly reduced, which extends the life of your asphalt. This helps you avoid costly repairs or repaving.

As an added benefit, it also speeds the melting of snow and ice! To get the most life out of your asphalt, we recommend having asphalt sealer applied every 2-3 years.

Asphalt Sealcoating Increases Your Curb Appeal

In addition to extending the life of your asphalt, sealcoating also helps keep it looking new. New asphalt is black while older asphalt that has not been sealed looks gray and run-down. After fresh asphalt coating is applied, your parking lot will be restored to that deep black color, adding curb appeal to your property.

The Asphalt Sealcoating Process

  1. We start by thoroughly cleaning the asphalt to remove all dust and debris.
  2. Then we prepare the sealcoat by adding up to 4 lbs of sand per gallon of sealant. This helps prevent additional wear and decreases the slickness of the coating.
  3. The sealcoat is applied.
  4. Once the sealcoat has dried and set, we re-stripe and re-mark the surface according to your needs and ADA regulations.

Asphalt Sealer Does Not Repair Asphalt

If your asphalt is already severely cracked or damaged, asphalt sealcoating will not repair the damage. To repair asphalt we recommend an asphalt overlay or complete repaving, depending on the extent of the damage. Once the overlay or new asphalt has been applied, we can seal it so it’s protected from the very beginning.

Asphalt Sealcoating FAQ’s

Is Sealing Asphalt Necessary?

Having asphalt surfaces sealcoated isn’t 100% necessary but the advantages of sealing make it a good decision for most surfaces. Sealcoating will allow your asphalt surface to last much longer than a surface that isn’t sealed, which means you’ll spend less money on maintenance of the surface. If you invest the money to have asphalt installed on a residential property or commercial property, we highly recommend that you have it sealcoated as well to properly protect your investment.

How Often Should Asphalt Be Sealed?

How often asphalt should be sealed is totally dependent on the surface. Each surface has a variety of different factors to consider such as the weather in the area, how much physical traffic is on the surface each day, how well the asphalt was installed in the first place, etc. We recommend that you have a pavement professional take a look at your surface to give you an accurate answer to how often it should be sealed.

How Long Do You Wait Before You Seal Asphalt?

Typically asphalt requires at least 90 days for it cully harden and cure. During this time the asphalt is strengthening and it is important to not seal the surface until this process is completely over. We recommend that you wait at least 90 days before you seal asphalt, it can be beneficial to wait even longer than the 90 day period to give the asphalt as much time as possible to solidify.

How Long Does It Take For Asphalt Sealer To Dry?

It typically takes roughly 4-6 hours for asphalt sealer to dry before it is protected against rain or other light weather. We typically recommend that you give your sealer as much time as possible before it is impacted by outside forces such as weather or physical traffic.

Does Asphalt Need To Be Cleaned Before Sealing?

We recommend that the asphalt is properly cleaned and polished before we begin the sealing process as this allows the sealcoating to connect directly to the asphalt without any debris getting in the way. Cleaning the asphalt before sealing will give you a better result with better protection for your surface. We have found that cleaning the surface plays a role in helping the surface have a longer lifespan.

How Much Does It Cost To Seal Asphalt?

The cost of the project has a variety of different factors that will influence the overall price. As a small driveway sealing will cost much less compared to a three-lane asphalt highway that needs to be sealed. We typically will give each surface a thorough diagnosis to make sure that sealcoating is a good fit for the surface and then come up with a cost that includes the amount of labor hours and material costs for the project.
