When Should You Seal Asphalt Pavement in Winchester, NV? Best Weather Temperature, Humidity & More

Sealcoating is an essential maintenance task for asphalt pavements which extends their lifespan, enhances their appearance and more. However, the timing of this task is important. Not only does the effectiveness of sealcoating depend on the method and materials used, but also heavily on the weather conditions at the time of application. Choosing the right time of year to sealcoat can make the difference between a durable, protective coating and a wasted effort. Andersen Asphalt & Striping would like to share some of the best times of the year to have sealcoating done and the reasons behind these choices.

Understanding Sealcoating

It is important to understand what sealcoating involves. Sealcoating is the application of a protective layer over an asphalt surface to guard against damage from UV rays, rain, chemicals, and wear and tear. This protective barrier not only extends the pavement’s life but also restores its rich, black appearance.

Ideal Conditions for Sealcoating

Temperature: Sealcoating requires warm temperatures for proper curing and adhesion. The temperature should ideally be above 50 degrees Fahrenheit during application and for several hours afterward. This is why late spring through to early fall is often considered the best time for sealcoating in most climates.
Humidity: Low to moderate humidity levels are ideal for sealcoating. High humidity can slow down the curing process, potentially leading to uneven drying and less effective protection.
Dry Weather: It is important that the weather is dry both during and after application, at least 24-48 hours post-application. Rain can wash away the sealant before it has a chance to dry properly, diminishing its effectiveness.

Seasonal Recommendations for Sealcoating

Spring: Late spring is often ideal for sealcoating. The temperatures are typically within the perfect range, and in many areas, the rainy season has passed. This timing also prepares the pavement to withstand the upcoming summer heat and heavy traffic, especially in commercial areas.
Summer: Early to mid-summer can also be a good time for sealcoating, provided the heat is not excessive. Extreme temperatures can cause the sealcoat to dry too quickly, which can lead to cracks and an uneven surface. Morning or late evening applications are recommended during hot days.
Fall: Early fall is another good time of the year for sealcoating. Similar to spring, temperatures are usually moderate, and the excessive summer heat has cooled. Getting the sealcoating done before the leaves fall and rain increases can protect the asphalt from winter damage.
Winter: Winter is generally not recommended for sealcoating due to low temperatures and high precipitation levels in many regions. However, in warmer climates, where temperatures rarely drop below 50 degrees, winter applications is still possible.
