Asphalt Sealcoating: What Is It and Why Is It So Important?

Asphalt surfaces, whether roadways, parking lots, or driveways, are an essential part of our daily lives. These surfaces are continuously exposed to various elements, such as sunlight, water, and chemicals, which can lead to their deterioration over time. Asphalt sealcoating is a vital maintenance process that helps preserve and extend the life of these surfaces. This blog post explores what asphalt sealcoating is and why it is an essential aspect of maintaining the integrity and aesthetics of your asphalt pavement.

What Is Asphalt Sealcoating?

Asphalt sealcoating is a protective coating that is applied over the surface of an asphalt pavement. This coating acts as a barrier between the asphalt and the various elements that can cause damage and deterioration. Sealcoating is typically made from a mixture of water, emulsified asphalt, and various mineral fillers, which together form a thin, liquid solution that can be easily applied to the pavement’s surface.

The primary purpose of sealcoating is to protect the asphalt from the damaging effects of the elements, as well as to maintain its appearance and prolong its lifespan. It does this by sealing the small cracks and pores in the pavement, preventing water, chemicals, and debris from entering and causing further deterioration.

Why Is Asphalt Sealcoating Important?

There are a couple of reasons asphalt sealcoating has become vital in many asphalt applications:

1. Protection from the Elements

One of the primary reasons for sealcoating is to protect the asphalt from the harmful effects of the sun, rain, and other environmental factors. Ultraviolet (UV) rays from the sun can cause the asphalt’s binder to break down, leading to cracks and potholes. Water, on the other hand, can seep into the cracks and cause further damage by eroding the base layers of the pavement. Sealcoating acts as a barrier that protects the pavement from these elements, reducing the risk of damage and costly repairs.

2. Aesthetics

Sealcoating not only protects your asphalt but also improves its appearance. Over time, asphalt surfaces can fade and wear due to exposure to the elements. Applying a sealcoat restores the deep black color of the asphalt and gives it a fresh, new look. This can be particularly beneficial for commercial properties, as an attractive and well-maintained parking lot or driveway can create a positive first impression for potential customers.

3. Cost-Effectiveness

Asphalt surfaces can be expensive to repair or replace. Regular sealcoating can help extend the life of your pavement, making it a cost-effective solution in the long run. By protecting the surface from damage and maintaining its appearance, sealcoating helps you avoid the need for costly repairs or early replacement of the pavement.

4. Safety

Cracks and potholes in asphalt surfaces can create safety hazards for pedestrians and vehicles. Sealcoating helps to prevent the formation of these hazards by sealing small cracks and maintaining the integrity of the pavement. Additionally, many sealcoating products contain additives that increase the skid resistance of the surface, improving safety for both pedestrians and motorists.

When Should Asphalt Sealcoating Be Performed?

Asphalt sealcoating should be performed regularly to ensure maximum protection for your pavement. It is generally recommended that a new asphalt surface should be seal coated within the first 12 to 18 months of installation. After the initial sealcoating, it is advisable to reapply the seal coat every 2-3 years, depending on the amount of traffic and exposure to the elements.


Asphalt sealcoating is an essential aspect of pavement maintenance that helps protect the surface from the damaging effects of the elements, maintains its appearance, and prolongs its lifespan. With regular sealcoating, you get to enjoy a cost-effective solution that can help you avoid costly repairs and early replacement of your pavement.
