Sealcoating

Driveway sealcoating is a process used to protect and enhance the appearance of asphalt driveways. It involves applying a protective layer, typically made from a mixture of asphalt or coal tar pitch, water, sand, and additives, to the surface of the driveway. Here are the key points about driveway sealcoating:

Benefits of Driveway Sealcoating

1. Protection from Elements:

   • Weather: Sealcoating helps protect the driveway from damage caused by rain, snow, and UV rays.
   • Oxidation: It prevents the oxidation of the asphalt binder, which can lead to brittleness and cracking.

2. Prevention of Damage:

   • Water Penetration: Sealcoating creates a barrier that prevents water from seeping into the asphalt, reducing the risk of potholes and cracks.
   • Chemical Spills: It guards against damage from oil, gasoline, and other chemicals that can degrade asphalt.

3. Aesthetic Improvement:

   • Appearance: A freshly sealcoated driveway looks new, with a uniform black surface that enhances curb appeal.

4. Extended Lifespan:

   • Durability: Regular sealcoating can significantly extend the life of an asphalt driveway by protecting it from the elements and wear and tear.

Process of Sealcoating

1. Preparation:

   • Cleaning: The driveway must be thoroughly cleaned to remove dirt, debris, and stains. This may involve sweeping, power washing, and using cleaners for oil spots.
   • Repairing: Cracks and potholes should be repaired before sealcoating. This ensures a smooth and even application.

2. Application:

   • Mixing: The sealcoating material is mixed to ensure uniform consistency.
   • Application Methods: The sealcoat can be applied using a brush, squeegee, or sprayer.
   • Coverage: It is important to apply the sealcoat evenly to avoid streaks and ensure complete coverage.

3. Curing:

   • Drying Time: The driveway needs to cure for at least 24-48 hours before it can be used. This allows the sealcoat to set and provide maximum protection.

Frequency of Sealcoating

• Initial Application: Typically, an asphalt driveway should be sealcoated within the first year of installation.
• Maintenance: After the initial sealcoating, it is recommended to reapply every 2-3 years,
