Sealing an asphalt surface is a preventive maintenance measure with several key benefits. Here’s why you should seal coat asphalt:
- Protection from Water Damage:
Asphalt is porous, allowing water to seep in and cause damage. Seal coating creates a protective barrier that prevents water penetration, reducing the risk of cracks, potholes, and erosion.
- UV Protection:
The sun’s ultraviolet rays can break down the asphalt’s chemical bonds, leading to fading, brittleness, and deterioration. Seal coating helps reflect UV rays, slowing the aging process.
- Oil and Chemical Resistance:
Vehicles often leak oil, gasoline, and other chemicals that soften and damage asphalt. Seal coating provides a resistant layer to protect against these substances.
- Prevention of Oxidation:
Asphalt oxidizes over time, becoming dry and brittle. Seal coating minimizes oxidation, helping to maintain the asphalt’s flexibility and extending its lifespan.
- Enhanced Appearance:
A seal coat gives asphalt a fresh, black finish, improving the overall aesthetic of driveways, parking lots, and roads.
- Cost Savings:
Regular maintenance, including seal coating, is significantly cheaper than repairing or replacing damaged asphalt. It extends the life of the surface, saving on significant repair costs.
- Smoother Surface:
Seal coating fills minor cracks and surface imperfections, creating a smoother surface that is easier to sweep and maintain.
How Often to Seal Coat
Most experts recommend seal coating asphalt every two to three years, depending on traffic volume, climate, and wear. Avoid over-application, as excessive sealant can cause peeling and cracking.
Investing in seal coating protects your asphalt surface from premature deterioration, enhancing both durability and appearance.
