How Sealcoating Shields Against UV and Oxidation
Sealcoating is an essential maintenance step that protects asphalt surfaces from the damaging effects of ultraviolet (UV) rays and oxidation. In cities like Sarnia, where weather and environmental factors can accelerate pavement wear, understanding the benefits of sealcoating is crucial for long-lasting, attractive parking lots and roadways.

What Is Sealcoating?
Sealcoating is the process of applying a protective liquid coating to asphalt surfaces. This coating acts as a barrier against external elements such as water, oil, and harmful UV rays. Capital Parking Lot Line Painting, a leading company in Sarnia, offers professional sealcoating services designed to extend the life of your asphalt and maintain its visual appeal.
How UV Rays and Oxidation Damage Asphalt
The Role of UV Rays
Ultraviolet rays from the sun cause the asphalt binder to dry out and become brittle over time. This leads to cracks and surface deterioration, making the pavement more susceptible to damage from daily traffic and weather conditions.
Understanding Oxidation
Oxidation is a chemical reaction where the asphalt binder reacts with oxygen in the air. This process hardens the binder, reducing its flexibility and causing premature cracking and surface wear. In Sarnia, where seasonal temperature fluctuations are common, oxidation can accelerate if the asphalt is left unprotected.
Benefits of Sealcoating Your Asphalt
Sealcoating provides multiple advantages that help combat UV damage and oxidation, including:
- UV Protection: The sealcoat acts as a shield blocking harmful rays from breaking down asphalt oils.
- Oxidation Prevention: It slows the chemical aging process, preserving the asphalt’s flexibility.
- Water Resistance: Prevents water penetration that can cause potholes and further surface damage.
- Enhanced Appearance: Restores a deep black finish, improving curb appeal for businesses and property managers.
- Cost Efficiency: Extends pavement life, reducing the need for costly repairs or full replacement.

Common Mistakes to Avoid When Sealcoating
- Skipping Surface Preparation: Failing to clean or repair surfaces leads to poor adhesion.
- Applying in Poor Weather: Sealcoating during rain or extreme temperatures reduces effectiveness.
