What Are the Benefits of Sealcoating Asphalt?

Asphalt surfaces are commonly used in driveways, parking lots, and roads due to their durability and cost-effectiveness. However, over time, these surfaces can deteriorate and become prone to cracks and other damages. That’s where sealcoating comes in. Sealcoating is a protective layer that is applied to asphalt surfaces to enhance their lifespan and reduce the need for expensive repairs. In this blog post, we will explore the benefits of sealcoating asphalt.

1. Extends the Lifespan of Asphalt

One of the primary advantages of sealcoating asphalt is that it helps extend the lifespan of the surface. Asphalt surfaces are constantly exposed to harsh weather conditions, UV rays, and chemicals from vehicles. Over time, these elements deteriorate the asphalt binder, causing the surface to weaken and develop cracks. By applying sealcoating, you create a protective layer that prevents the penetration of damaging elements, shielding the asphalt from premature deterioration. Regular sealcoating can significantly prolong the life of your asphalt surface, saving you from costly repairs or total replacement.

2. Prevents Water Damage

Water is one of the major culprits behind asphalt deterioration. When water seeps into the cracks and crevices of an unsealed asphalt surface, it can freeze and expand during colder temperatures, leading to further cracking and potholes. Sealcoating acts as a waterproof barrier, preventing water penetration and reducing the risk of damage caused by freezing and thawing cycles. By preventing water damage, sealcoating ensures a longer lifespan for your asphalt surface and saves you money on repairs.

3. Protects Against Oxidation and UV Rays

Another benefit of sealcoating asphalt is that it protects against oxidation and UV rays. Over time, exposure to sunlight causes asphalt to oxidize, leading to the formation of a dry and brittle surface. This can make the asphalt more susceptible to cracking and crumbling. Additionally, UV rays can fade the color of the asphalt, making it less visually appealing. Sealcoating blocks UV rays from reaching the asphalt surface, preserving its appearance and preventing oxidation. By protecting against oxidation and UV rays, sealcoating helps maintain the structural integrity and aesthetics of your asphalt.

4. Enhances Asphalt Appearance

Asphalt sealcoating not only protects your surface but also enhances its appearance. The application of a sealcoat gives your asphalt a smooth, sleek, and uniform look, instantly improving its curb appeal. Whether it’s a commercial parking lot or a residential driveway, a fresh coat of sealcoating can make a significant difference in the overall appearance of your property. The dark black color of sealcoated asphalt also helps to hide stains and spills, making it easier to maintain a clean and attractive surface.

5. Increases Safety

Sealcoating plays a crucial role in increasing the safety of asphalt surfaces. The smooth finish created by sealcoating helps to reduce friction on the surface, making it easier for vehicles to navigate and decreasing the risk of skidding. Additionally, sealcoating fills in small cracks and fissures, preventing them from expanding and becoming trip hazards. By enhancing the safety of your asphalt surface, sealcoating provides peace of mind for both property owners and users.


Sealcoating is an essential maintenance practice that offers numerous benefits for asphalt surfaces. From extending the lifespan of your asphalt to preventing water damage and increasing safety, sealcoating provides a cost-effective solution to protect and enhance your asphalt surfaces. Regular sealcoating can save you money on repairs while maintaining the aesthetics and functionality of your asphalt for years to come. So, if you want to maximize the lifespan of your asphalt surface and improve its appearance, sealcoating is definitely the way to go!
