When Is the Best Time to Sealcoat Your Parking Lot?


Maintaining the condition of your parking lot is essential to the safety of your customers and employees. One of the most effective ways to do this is by sealcoating. Sealcoating is the process of applying a protective coating to the surface of the asphalt, which helps fend off natural elements such as water, snow, and UV rays. While this is a beneficial process, it’s important to know when is the best time to do it to ensure maximum protection. This blog will give you the information you need to determine the best time for sealcoating.


Before diving into the best time to sealcoat, it’s essential to understand the two primary reasons for sealcoating: to protect the asphalt and enhance its appearance. When determining the right time to apply the sealcoat, both reasons must be weighed since they have different requirements.

Typically, the best time to apply the sealcoat is in the summer, late spring, or early fall. A temperature of about 50°F or higher, combined with lower humidity, will provide the best conditions for a high-quality, long-lasting sealcoat. This temperature range allows for quick drying, ensuring the job is completed without any complications.

While summer is the ideal season for sealcoating, it’s not always accessible for everyone. The fall is another great option, to start the process. In addition, early spring or late winter can also work out, depending on the weather condition. However, applying sealcoat during a small window of time may have it work, but it's essential to understand that a lack of ideal conditions can have an effect on the duration of the sealcoat.

Keep in mind that the temperature of the asphalt must also be considered. The asphalt surface must be dry and warm to the touch. The surface’s temperature must also be checked, ensuring it is between 50°F and 85°F before the application of sealant.

Finally, if you want to extend the life of your asphalt, resist applying sealcoat as soon as your parking lot is paved. After installation, asphalt requires about 90 days to cure fully. Therefore, if you apply sealcoat too fast, the curing process will be hindered, leading to more harm than good.



Sealcoating protects your pavement from the natural elements such as water, UV rays, and snow, as well as improves the appearance, which can increase the value of your business. Deciding on the best time to sealcoat your asphalt parking lot should be taken seriously, keeping in mind the appearance and quality of the work. From the information provided, the ideal time to apply sealcoat is in the summer, followed by early fall or late spring.
