Why and How to Sealcoat Your Asphalt Surfaces

Sealcoating is an essential maintenance technique that extends the lifespan and enhances the appearance of asphalt surfaces. Whether it's a driveway, parking lot, or pathway, applying a sealcoat is a crucial preventive measure that protects against various damaging factors. At Lawn Harmony Landscaping, we specialize in this service and are here to provide a detailed guide on why sealcoating is vital and how to do it effectively.


The Importance of Sealcoating


1. Protection Against Elements:

  • Moisture Barrier: Sealcoating prevents water from penetrating asphalt, reducing the risk of potholes, cracks, and other damage caused by freeze-thaw cycles.

  • UV Damage: It acts as a sunblock for your asphalt, protecting it from oxidation and the fading caused by UV rays.

2. Enhances Aesthetic Appeal:

  • Visual Improvement: A fresh sealcoat provides a dark, rich color that makes older asphalt look new, significantly boosting the curb appeal of your property.

3. Increases Lifespan:

  • Cost-Effective: By regularly sealcoating, you can double the lifespan of your asphalt, delaying expensive repaving costs.


Step-by-Step Guide to Sealcoating


4. Assess and Prepare the Surface:

  • Cleaning: Start by thoroughly cleaning the asphalt surface. Remove all dirt, debris, and oils using a broom, pressure washer, or professional cleaning equipment.

  • Repair: Fill in cracks and potholes with an appropriate asphalt patch product. Smooth and compact these repairs to create a uniform surface.

5. Choose the Right Sealcoat Product:

  • Types of Sealcoat: Select a sealcoat that suits your climate and traffic conditions. Consult with a professional to find the best product that offers durability and longevity.

6. Application Techniques:

  • Tools Needed: Depending on the size of the area, you might use a squeegee, brush, or a sprayer to apply the sealcoat. Larger commercial areas often require a sprayer for a more efficient and even application.

  • Application Process:

  • Mixing: Stir the sealcoat thoroughly to ensure it’s well-mixed.

  • First Coat: Apply the first coat and allow it to dry completely, usually taking a few hours.

  • Second Coat: Apply a second coat if necessary, particularly on high-traffic areas, to ensure complete coverage and protection.

7. Drying and Curing Time:

  • Cure Time: Allow the sealcoat to cure for at least 24 hours before allowing traffic on the surface. Avoid sealing on rainy days or when temperatures are too low for proper curing.


Best Practices for Sealcoating


8. Regular Maintenance:

  • Frequency of Sealcoating: It is recommended to sealcoat asphalt surfaces every 2-3 years to maintain optimal protection and appearance.

  • Seasonal Considerations: Plan sealcoating for dry, warm months to ensure the best adherence and curing of the sealant.

9. Environmental and Safety Precautions:

  • Eco-friendly Options: Consider using environmentally friendly sealcoat products that are free from harmful PAHs (polycyclic aromatic hydrocarbons).

  • Safety Gear: Always wear appropriate safety gear when applying sealcoat, including gloves, goggles, and respiratory protection if necessary.
