How to Choose the Best Sealcoating for Your Parking Lot
Sealcoating is a critical part of parking lot maintenance, acting as a protective barrier that extends the life of asphalt while improving its appearance. Without proper sealcoating, asphalt is vulnerable to UV rays, oil spills, water infiltration, and weather damage, leading to premature deterioration and costly repairs.
With several types of sealcoating available, property managers must carefully choose the right option for their specific needs. In this guide, we’ll explore the different sealcoating types, their benefits, best practices, and long-term strategies for maintaining a durable parking lot surface.
Why Sealcoating is Essential for Parking Lots
1. Protection Against the Elements
Asphalt is constantly exposed to sun, rain, and temperature fluctuations, all of which contribute to its breakdown over time. UV rays dry out the asphalt binder, leading to cracks and surface deterioration. Rain and moisture seep into small crevices, causing potholes and structural damage. Sealcoating acts as a shield, preventing water infiltration and oxidation.

2. Improved Durability and Longevity
A well-maintained sealcoating layer helps asphalt last twice as long as unprotected surfaces. It reduces cracking, protects against chemical spills, and prevents premature wear from vehicle traffic.
3. Enhances Curb Appeal
A freshly sealcoated parking lot looks brand new, providing a smooth, dark black surface that enhances the overall aesthetic of a business or commercial property. A well-maintained parking lot can increase property value and leave a positive first impression on customers.
4. Cost Savings
Regular sealcoating minimizes the need for expensive repairs and extends the lifespan of the pavement, ultimately saving property owners thousands of dollars in resurfacing or replacement costs.

Types of Sealcoating: Which One is Right for You?
There are several types of sealcoating materials, each with its own advantages and best-use scenarios. Understanding the differences can help you make the best decision for your parking lot.
1. Coal Tar Sealers
✅ Durability: Extremely resistant to UV rays, oil, and gas spills.
✅ Lifespan: Lasts up to 5 years with proper maintenance.
✅ Best For: High-traffic commercial parking lots.
🚫 Drawback: Contains higher levels of volatile organic compounds (VOCs), which can create environmental concerns.
2. Asphalt-Based Emulsion Sealers
✅ Eco-Friendly: Lower VOC emissions compared to coal tar.
✅ Adhesion: Bonds well with asphalt surfaces.
✅ Best For: Residential driveways and low-traffic areas.
🚫 Drawback: Less resistant to chemical spills than coal tar.
3. Acrylic Sealers
✅ Color Options: Available in various colors for customization.
✅ Weather Resistance: Highly resistant to UV rays.
✅ Best For: Decorative parking lots, walkways, and specialty applications.
🚫 Drawback: More expensive than traditional sealers.
4. Fast-Dry Sealers
✅ Quick Application: Dries faster, allowing for faster reopening of the parking lot.
✅ Best For: Businesses needing minimal downtime.
🚫 Drawback: May require more frequent applications.
How to Choose the Best Sealcoating for Your Parking Lot
1. Consider Traffic Volume
- High-traffic commercial lots: Coal tar or acrylic sealers for maximum durability.
- Medium to low-traffic lots: Asphalt emulsion or fast-dry sealers.
2. Evaluate Environmental Impact
If sustainability is a concern, asphalt-based emulsion or acrylic sealers are preferable due to their lower VOC emissions compared to coal tar sealers.
3. Think About Climate Conditions
- Hot & sunny climates: UV-resistant sealers like acrylic.
- Cold & wet climates: Coal tar provides excellent waterproofing.
4. Factor in Maintenance Frequency
Some sealcoating materials require more frequent reapplications than others. If long-term cost savings are a priority, choosing a durable sealer that lasts longer may be the best option.
5. Consult a Professional
A professional paving contractor can assess your parking lot condition and recommend the best sealcoating solution based on usage, weather exposure, and traffic patterns.

Best Practices for Sealcoating Application
1. Prepare the Surface Properly
Before applying sealcoating, the asphalt must be clean and free of debris, oil, and cracks. Any potholes or cracks should be repaired in advance to ensure a smooth application.
2. Apply at the Right Temperature
For best results, sealcoating should be applied when temperatures are between 50-85°F and during dry weather conditions. Avoid application during rain or extreme humidity.
3. Allow Proper Drying Time
Most sealcoatings require at least 24-48 hours to fully cure before reopening the parking lot to traffic. Fast-dry options can reduce downtime significantly.
4. Maintain a Routine Sealcoating Schedule
- Apply sealcoating every 2-3 years for optimal protection.
- Inspect annually for signs of wear and fading.
