About Asphalt Sealcoating
What is Sealcoating?
Sealcoating is a protective layer applied to asphalt surfaces to shield them from damage caused by UV rays, water, oils, and chemicals. It's a preventative maintenance measure that extends the life of your asphalt driveway or parking lot by 5-10 years when applied regularly.
Benefits of Sealcoating
- •Protects against water penetration and freeze-thaw damage
- •Prevents oxidation and deterioration from UV rays
- •Resists oil and chemical spills that can damage asphalt
- •Enhances appearance with a fresh, black finish
- •Saves money by extending pavement life and reducing repairs
When to Sealcoat
New asphalt should cure for at least 6 months before the first sealcoating. After that, residential driveways should be sealcoated every 2-3 years, while commercial parking lots may need treatment every 1-2 years due to heavier traffic.
Pro Tip
The best time to sealcoat is during warm, dry weather with temperatures between 50-90°F (10-32°C). Allow 24-48 hours of dry weather after application before using the surface.
Types of Sealcoat
- •Coal Tar Emulsion: Traditional option with excellent fuel resistance
- •Asphalt Emulsion: More environmentally friendly alternative
- •Acrylic Sealers: Premium option with enhanced durability and color retention
Sealcoating Process
Preparation
Surface is cleaned thoroughly to remove dirt, debris, and oil stains. Cracks are filled, and damaged areas are repaired.
Application
Sealcoat is applied in thin, even layers using spray equipment or squeegees. Two coats are typically recommended for best results.
Curing
Surface needs 24-48 hours to cure completely before vehicle traffic. Pedestrian traffic can usually resume after 12 hours.
Sealcoating Coverage Rates
Factors Affecting Sealcoating Costs
Surface Area
Larger areas typically have lower per-square-foot costs due to economies of scale. Small driveways may cost $0.25-0.50/sq ft while large parking lots might be $0.15-0.35/sq ft.
Surface Condition
Heavily damaged surfaces require more preparation work, increasing overall costs. Extensive cleaning, crack filling, and repairs can add 20-50% to the base price.
Accessibility
Difficult access for equipment and materials can increase labor costs. Areas with limited access may require more manual labor, adding 10-25% to the cost.
Sealant Quality
Premium sealants with additives like sand for traction, latex for durability, or fast-drying agents cost more but last longer and provide better protection.
Geographic Location
Labor rates and material costs vary by region. Urban areas typically have higher costs than rural areas due to higher labor rates and business expenses.
Application Method
Spray application is faster but less durable. Squeegee application provides better coverage and penetration but costs more due to increased labor time.

- • Fill cracks and repair damaged areas
- • Trim edges and remove vegetation
- • Allow surface to dry completely
Sealcoat Application
- • Apply first coat with sprayer or squeegee
- • Work in small sections for even coverage
- • Allow first coat to dry (2-4 hours)
- • Apply second coat (if specified)
- • Ensure consistent coverage
Curing & Aftercare
- • Allow 24-48 hours for complete curing
- • Keep all traffic off surface during curing
- • Avoid parking in the same spots repeatedly
- • Clean up oil spills promptly
- • Plan for reapplication every 2-3 years
Pro Tips for Successful Sealcoating
Timing is Everything
Apply sealcoat when temperatures are between 50-90°F (10-32°C) with no rain in the forecast for 24-48 hours. Late spring through early fall is typically ideal.
Thorough Preparation
The most important step is proper cleaning and preparation. A clean, dry surface ensures proper adhesion and longer-lasting results.
Two Thin Coats
Two thin coats provide better protection than one thick coat. Allow the first coat to dry completely before applying the second.
Avoid Common Mistakes
Don't apply sealcoat too thick, skip proper preparation, or allow traffic before complete curing. These mistakes can lead to peeling, flaking, and premature failure.
Weather Considerations:
Ideal application conditions include temperatures between 50-90°F (10-32°C), low humidity, and no rain in the forecast for at least 24-48 hours. Avoid applying sealcoat in direct sunlight on extremely hot days, as it can dry too quickly and not properly penetrate the asphalt.
