What is Asphalt Seal Coating?

Asphalt seal coating is a protective layer applied to asphalt pavements to safeguard them against the elements and prolong their lifespan. Comprising a mixture of emulsified asphalt, water, mineral fillers, and additives, seal coating acts as a barrier against UV rays, water penetration, and chemicals that can degrade asphalt surfaces.

Benefits of Asphalt Seal Coating

  1. Preservation of Asphalt Surface
    So, asphalt seal coating prevents oxidation and deterioration caused by exposure to sunlight and air, preserving the structural integrity of the asphalt.
  2. Enhanced Aesthetic Appeal
    The dark, smooth finish provided by seal coating enhances the curb appeal of properties, making them more attractive and inviting.
  3. Cost-Effective Maintenance
    Compared to extensive repairs or replacements, regular seal coating is a cost-effective preventive maintenance measure that extends the life of asphalt surfaces.

When Should You Seal Coat Your Asphalt?

  1. Newly Laid Asphalt
    It is advisable to seal coat new asphalt surfaces after they have cured for approximately six months to protect them from early wear and tear.
  2. Every 2-3 Years
    For existing asphalt surfaces, reapplying seal coat every 2-3 years helps maintain optimal protection and appearance, depending on traffic and environmental conditions.

The Seal Coating Process

  1. Surface Preparation
    Proper cleaning and preparation of the asphalt surface, including filling cracks and repairing potholes, ensure a smooth and uniform application of seal coat.
  2. Application of Seal Coat
    Seal coating is typically applied with specialized equipment such as squeegees or spray systems to achieve an even layer that adheres well to the asphalt surface.
  3. Curing and Drying
    Allow sufficient time for the seal coat to cure and dry completely, usually 24-48 hours depending on weather conditions, before allowing traffic on the surface.

Choosing the Right Seal Coating Contractor

  1. Experience and Reputation
    Select a contractor with experience in seal coating and a reputation for delivering quality workmanship and customer satisfaction.
  2. Quality of Materials
    Ensure that the contractor uses high-quality seal coating materials that comply with industry standards for durability and performance.
  3. Cost-Effectiveness
    While cost is a consideration, prioritize value and long-term benefits over the lowest bid to ensure a durable seal coating application.


Investing in asphalt seal coating not only protects your pavement investment but also enhances its appearance and extends its lifespan. By understanding the process and benefits of seal coating, property owners can make informed decisions to maintain their asphalt surfaces effectively.
