Seal coating is a crucial maintenance procedure that extends the lifespan and enhances the appearance of asphalt surfaces. Understanding the science behind seal coating can help homeowners appreciate its importance and ensure that they undertake this maintenance at the right intervals. At Lawn Harmony Landscaping, we specialize in providing top-quality seal coating services designed to protect your investment in asphalt paving. Here's a deep dive into how seal coating works and why it's beneficial for your asphalt surfaces.
What is Seal Coating?
Seal coating involves applying a protective layer over asphalt pavements to shield them from the damaging effects of weather, traffic, and chemicals. The sealant used is usually a coal-tar or asphalt-based emulsion that seals the surface of the asphalt to prevent water, oils, and UV damage.
How Seal Coating Protects Asphalt
1. Protection Against Water Damage:
Moisture Barrier: Water is one of the biggest enemies of asphalt, causing it to break down and form cracks or potholes over time. Seal coating provides a waterproof barrier that prevents water from penetrating the asphalt, thereby reducing the risk of structural damage.
2. UV Radiation Defense:
Oxidation Prevention: Ultraviolet (UV) rays from the sun can cause the asphalt binder (the glue that holds the aggregate together) to oxidize and become brittle, leading to cracking and deterioration. Seal coating helps block these UV rays, maintaining the flexibility and integrity of the asphalt.
3. Resistance to Oil and Chemical Spills:
Chemical Protection: Asphalt is susceptible to damage from oil, gasoline, and other chemicals. These substances can soften asphalt, leading to surface degradation over time. Seal coating creates a barrier that prevents these chemicals from directly contacting the asphalt.
The Process of Seal Coating
4. Surface Preparation:
Cleaning: The existing asphalt must be thoroughly cleaned to remove dirt, debris, and any existing oil spots. This ensures that the sealant adheres properly to the asphalt surface.
Repair Work: Any cracks or potholes should be repaired before the seal coating application to ensure a smooth, uniform surface.
5. Application Techniques:
Method of Application: Sealant can be applied using a squeegee, brush, or sprayer depending on the size of the area and specific conditions.
Curing Time: After application, the sealant needs to cure for 24-48 hours before the pavement can be used. Curing times can vary based on temperature and humidity levels.
Long-Term Benefits and Maintenance
6. Extending Pavement Life:
Lifespan Increase: Regular seal coating, typically every 2-3 years, can double the life expectancy of an asphalt pavement by protecting it from the elements and wear.
Cost-Effectiveness: By extending the pavement's lifespan, seal coating reduces the frequency and severity of repairs and delays the need for expensive resurfacing or replacement.
7. Aesthetic Improvement:
Enhanced Appearance: Seal coating gives asphalt a fresh, new, dark appearance, enhancing the curb appeal of the property.
