Protect Your Asphalt Before It Fails
Sealcoating is one of the most cost-effective ways to extend the life of your parking lot or driveway. Regular maintenance helps protect asphalt from water, UV exposure, oxidation, oil stains, and the harsh freeze-thaw cycles common in the Pacific Northwest.
Without sealcoating, asphalt can age and fail years earlier than expected.
Why Sealcoating Matters
Helps prevent water penetration Slows cracking and surface deterioration Protects against UV and oxidation Improves curb appeal with a fresh black finish Extends the life of your asphalt Built for Pacific Northwest Weather
Rain and temperature swings are hard on asphalt surfaces throughout Washington. Sealcoating acts as a protective barrier that helps reduce moisture damage and premature wear.
At FrontLine Lot Revival, every sealcoating project starts with an honest site evaluation to determine whether sealcoating is the right solution for your lot.
Our process includes:
- Surface cleaning and preparation
- Crack filling before sealing
- Asphalt emulsion application (optional second coat)
- Proper curing time before reopening traffic
- Optional restriping after curing
We do not cut corners with single-coat applications or low-grade products.
When Should You Sealcoat?
Most commercial lots should be sealcoated every 2–3 years, depending on traffic levels and weather exposure.
The Right Maintenance Order
For aging lots, the correct process is:
- Crack Fill
- Sealcoat
- Stripe
Skipping crack filling before sealcoating is one of the most common causes of early sealcoat failure.
Seasonal Scheduling
Sealcoating in the Pacific Northwest is typically performed between May and September to ensure proper curing and long-lasting results.
