Can Sealcoating Be Applied at Night?
Asphalt pavements are surprisingly economical, rapid to construct, and aesthetically pleasing. With proper installation and proactive maintenance, an asphalt pavement can deliver decades of use before it requires a reconstruction. One of the best ways to protect asphalt pavements against the ravages of UV rays and corrosive chemicals is to sealcoat them periodically. However, many property managers and owners question whether sealcoating operations can take place at night so that business operations are not disrupted. The short answer is that nighttime asphalt sealing may be technically possible, but it is seldom the wisest decision.
What Is the Problem With Sealcoating at Night?
There are several challenges involved when sealcoating parking lots or other asphalt pavements at night. The most obvious challenge is the reduced visibility that sealcoating contractors and their crew members will encounter; even the best artificial lights cannot fully duplicate sunlight. A second issue is that the sealant manufacturer may refuse to honor its product warranty unless the mix and application conform to the manufacturer’s specifications, and some specifications state that the sealant is not to be applied at night. Furthermore, the weather can make Treasure Coast sealcoating operations difficult enough without adding the complexity of nighttime applications. However, the most critical challenge involves the way that asphalt paving lot sealcoating cures.
Why Is Curing a Challenge for Nighttime Sealcoating Operations?
The liquid sealant used for parking lot sealcoating is about 70% water, and curing requires this water to evaporate. Evaporation is slower at cool temperatures and high humidity levels, but exposure to direct sunlight can counteract these negative impacts. Sunlight is so important to curing that sealant manufacturers recommend that their products receive at least four hours of sunlight before the pavement begins receiving traffic. Therefore, it is usually unrealistic to expect that applying parking lot sealcoating at night automatically guarantees that the pavement can be open to traffic first thing in the morning. There are additives that can be included in the mix that will force the sealant to dry faster, but sealcoating contractors must handle them carefully and pay meticulous attention to avoid substandard results.
Are There Alternatives to Sealcoating Parking Lots at Night That Help Avoid Disrupting Business Operations?
Experienced sealcoating companies know various ways to minimize disruptions when sealing asphalt pavements. However, you will need to discuss the possible alternatives with your contractor to select the best approach for your specific operation. For example, if your business is closed on weekends or certain holidays, your contractor may be able to sealcoat your parking lot on a day when your operations are shut down. If your business operates seven days a week, it might be possible for your contractor to divide your parking lot into sections that can be closed, sealed, and returned to service individually.
