Sealcoating is an important maintenance step for your asphalt pavement. Sealcoating provides a protective layer that helps to keep your pavement safe from the elements. This helps to increase the life span of your asphalt pavement. However, sealcoating cannot be completed all times of the year.
The biggest issue with sealcoating is that it must be fully dried for the process to be completed. If it is not fully dried then it can mess up the sealcoat and the protective benefits are removed. So it is important that the sealant is put on during a time that it can fully dry.
The 2 things that help the drying process for sealcoating are the sun and heat. The hotter it is the faster the sealcoat dries. Also the longer that the sun is out, the faster it is able to dry. As fall comes and the days get shorter, it takes longer for sealcoating to dry. It is important that sealcoating is applied at temperatures above 50 degrees and that it remains above 50 degrees during the drying process.
As with any pavement job, you are at the mercy of weather to get the job done. A job can be planned out, but if the weather is not cooperating then the job may be pushed back. It is best to get the job done right, rather than pushing ahead when the weather can cause some problems to the process. In the realm of sealcoating, you have to protect against rain which would cause problems. As the days get shorter and colder, it takes longer for sealcoating to dry, meaning that you have to take note of the weather for several days before deciding to have the job done.
It is important that you work with a trusted paving professional who will be honest about whether it is a good idea to sealcoat based on the weather.
Next year plan ahead and get sealcoating on your calendar before it gets too cold!
