Asphalt Seal Coating

Asphalt sealcoating is a preventative maintenance procedure to protect and prolong the longevity of parking lots. A sealer acts as a waterproofing agent, minimizing the rate at which water enters the pavement. Its protective coating also reduces the depth to which oil, gas, or other substances can permeate the surface and break down the asphalt substrate. Finally, it reduces oxidation and helps the parking lot maintain a jet-black color for longer.

Seal Coating or Resurfacing?

Even a perfect application of sealer will not repair cracks and other surface defects in asphalt parking lots. Our team can assess your parking lot to make sure the pavement is in proper condition to accept sealer. If there are widespread areas of deteriorated asphalt or if the pavement has been sealed too many times, for example, resurfacing may be necessary. Prior to applying sealer, our team will recommend addressing any surface defects including cracks, oil spots, potholes, and oxidized areas.

Our Local Sealcoating Contractors

Our sealcoating partners are local to your jobsite to ensure that sealer application occurs during proper temperature and weather conditions. Once complete, traffic should be kept off a newly sealed surface for a minimum of 18 to 36 hours. This timeframe is necessary for the asphalt sealer to dry and begin its initial cure.

How Often Should You Seal Coat?


After initial application (typically one year after construction), asphalt sealcoating should be budgeted for and performed every 24 to 36 months. If the process is done more frequently, sealer may build up on the asphalt – resulting in cracking and peeling. On the other hand, if too much time has passed without sealcoating, pavement will be exposed to the elements.

What Does Sealcoating Cost?

Asphalt sealcoating cost varies based on material and application process, both of which are dependent on a range of factors including pavement condition, climate, and location. With the help of our local sealcoating contractor network, we will advise you on the right product and process for your jobsite.

It is important to consider more than price, however, when choosing a parking lot sealer. For example, a polymer-modified or high-performing pavement sealer may cost 15-20% more up front, but add 50% longer life than a conventional product. This reduces the frequency of sealcoating applications, helps minimize disruption (due to lengthy drying/curing time), and lowers maintenance cost over the lifecycle of the pavement.

Work with a Local Expert in Sealcoating

In addition to material, the right application technique is crucial and will vary based on specific region and site condition. We work with local asphalt sealcoating contractors from our pre-qualified network who know the region and land quality to determine which application, i.e. spray system or squeegee, and number of coats is best for your jobsite.
