Learn why seal coating is essential for extending the life of your asphalt surfaces and how it can save you thousands in replacement costs.
What is Seal Coating?
Seal coating is a protective layer applied to asphalt surfaces that shields them from damaging elements like UV rays, water, oil, and chemicals. Think of it as sunscreen for your driveway or parking lot.
The Science Behind Seal Coating
Asphalt is made from aggregate (rocks and sand) bound together with a petroleum-based binder. Over time, this binder breaks down due to:
- UV radiation from the sun
- Water penetration from rain and snow
- Chemical exposure from oil, gas, and de-icers
- Oxidation from air exposure
Seal coating creates a barrier that protects against all these factors.
Benefits of Regular Seal Coating
1. Extended Lifespan
Properly maintained asphalt can last 25-30 years. Without seal coating, you might see significant deterioration in just 5-7 years.
2. Cost Savings
- Seal coating costs: $0.15-0.25 per square foot
- Asphalt replacement: $4-8 per square foot
The math is clear: regular seal coating saves money.
3. Enhanced Appearance
Fresh seal coating gives your property a clean, professional appearance. First impressions matter, especially for businesses.
4. Easier Maintenance
Sealed surfaces are easier to clean and maintain. Snow removal is more efficient, and debris doesn't accumulate in cracks.
When to Seal Coat
Ideal Conditions
- Temperature above 50°F for 24 hours
- No rain expected for 24-48 hours
- Spring or early fall are ideal seasons
Frequency
- New asphalt: Wait 6-12 months before first application
- Existing surfaces: Every 2-3 years
- High-traffic areas: May need annual application
The Seal Coating Process
1. Surface Preparation
We begin with thorough cleaning:
- Power washing
- Oil spot treatment
- Crack filling
- Weed removal
2. Application
Professional application ensures even coverage:
- Two coats for optimal protection
- Spray or squeegee application
- Edge trimming and detail work
3. Curing
Allow 24-48 hours before traffic resumes.
DIY vs. Professional Application
While DIY seal coating products exist, professional application offers:
- Better materials with higher solids content
- Proper preparation that ensures adhesion
- Even application without streaks or puddles
- Warranty coverage on workmanship
