What Does Seal Coating Protect Your Asphalt From?

Untreated asphalt is constantly under attack from the environment. Seal coating creates a protective barrier that defends against the five most common causes of asphalt deterioration in Eastern Washington.

01

UV Oxidation

Sunlight breaks down asphalt binders over time, turning the surface gray, brittle, and prone to cracking. Seal coating blocks UV exposure and slows that oxidation process significantly.

02

Water and Moisture

Water infiltration is the leading cause of pavement failure in Spokane. Seal coating creates a waterproof barrier that prevents moisture from reaching the subbase and causing structural damage.

03

Oil and Chemical Spills

Petroleum-based fluids soften asphalt binders and accelerate surface breakdown. A seal coat acts as a resistant barrier against oil, gas, and chemical damage from vehicle drips and spills.

04

Freeze-Thaw Cycles

Water that enters surface cracks expands when it freezes, breaking pavement apart from the inside out. Sealing surface pores prevents that cycle before it starts.

05

Traffic Wear

Daily vehicle traffic gradually abrades the asphalt surface. A fresh seal coat adds a protective layer that absorbs that wear and preserves the pavement underneath.

Integrity in Every Layer

How Does Cornerstone Paving WA Apply Seal Coating?

Every seal coating job at Cornerstone Paving WA follows a proven five-step process that ensures the sealant bonds correctly, covers evenly, and lasts the full 3 to 5 years it should.

1. Surface Cleaning

What happens before seal coating is applied?
We clean the entire surface, removing dirt, oil stains, and debris that would prevent the sealant from bonding correctly to the asphalt.

2. Crack and Edge Repair

Why is crack filling done before seal coating?
Existing cracks are filled and edges are addressed before any sealant goes down. Skipping this step is the most common reason seal coating fails prematurely.

3. Seal Coat Application

How is seal coating applied professionally?
The sealant is applied evenly across the entire surface using professional squeegee or spray equipment, ensuring consistent coverage and proper thickness from edge to edge.

4. Curing

How long does seal coating take to dry?
The seal coat cures for 24 to 48 hours depending on weather conditions. We give you a specific timeframe before we leave so you know exactly when the surface is ready for use.

5. Final Inspection

What happens at the end of a seal coating job?
We walk the entire surface before leaving to confirm even coverage, clean edges, and a consistent finish across the full area.

Maintenance

How Often Should You Seal Coat Your Driveway in Eastern Washington?

For most Spokane driveways, seal coating every 3 to 5 years is the recommended maintenance interval. The right timing depends on your specific situation.

New Asphalt Driveways

Wait 6 to 12 months after installation before applying the first seal coat. New asphalt needs time to fully cure and off-gas before a sealant will bond correctly.

High-Traffic Driveways

Driveways with heavy or frequent vehicle use benefit from seal coating every 2 to 3 years to keep the protective layer intact.

Visibly Faded or Gray Asphalt

If your driveway has lost its dark black color and looks dry or chalky, it is overdue for a seal coat. Do not wait until surface cracking begins.

Surfaces With Minor Cracking

Hairline or early surface cracks should be filled and sealed as soon as they appear. Acting early is always more affordable than waiting for damage to spread.

Common Questions About Seal Coating in Spokane, WA

What is seal coating and what does it do?
Seal coating is a protective liquid treatment applied over existing asphalt to block moisture, resist UV damage, and slow surface deterioration. It also restores the dark, clean appearance of the driveway.
A professionally applied seal coat typically lasts 3 to 5 years in Spokane. High-traffic driveways or surfaces with heavy sun exposure may need reapplication closer to every 2 to 3 years.
The surface is ready for light foot traffic within a few hours and vehicle use within 24 to 48 hours. We give you a specific timeframe based on weather conditions on the day of application.
Seal coating alone does not fill cracks. Existing cracks need to be filled and repaired before the sealant is applied. We handle both crack repair and seal coating as part of the same service visit.
If your asphalt is fading from black to gray, feels dry or brittle, or shows hairline surface cracking, it is time to seal coat. These are early signs of UV oxidation and moisture damage that seal coating can stop before they become structural problems.
Yes. The cost of seal coating is a fraction of what crack repairs, resurfacing, or full driveway replacement costs. Applied on a regular schedule, seal coating is the single most cost-effective maintenance decision a homeowner can make for their asphalt driveway.
