Protect your Flagstaff asphalt surfaces from harsh sun and winter elements with our durable sealcoating applications.

This coating, typically a refined coal tar emulsion or an asphalt-based emulsion, forms a barrier against environmental degradation. We ensure a clean, properly prepared surface before application, which means the sealcoat adheres effectively, providing a uniform, dark finish that enhances curb appeal and pavement longevity.
Our approach to sealcoating begins with a thorough inspection of your asphalt to identify any cracks or potholes that require repair. We then meticulously clean the surface using power blowers and wire brooms, removing all loose debris, dirt, and oil stains. This preparation is essential because even minor contaminants can compromise the bond of the sealcoat, leading to premature wear and peeling. We apply the sealcoat evenly, often in two coats, using specialized squeegees or spray equipment to achieve consistent coverage and thickness.
In Flagstaff, the high altitude and intense UV radiation are particularly harsh on asphalt, causing it to oxidize and become brittle much faster than in other climates. Our sealcoating acts as a sacrificial layer, absorbing the sun's damaging rays and preventing water penetration from snowmelt and monsoon rains. This protection is vital for preventing aggregate unraveling and crack formation, which are common issues here due to freeze-thaw cycles and temperature fluctuations.
Customers often ask about the best time to sealcoat. We recommend scheduling during warmer, dry periods, typically late spring through early fall in Flagstaff, when temperatures are consistently above 50°F (10°C) for at least 24-48 hours. This allows the sealcoat to cure properly, achieving its maximum durability and protective qualities. We also advise against heavy traffic for at least 24-48 hours post-application to ensure the material fully hardens.
Asphalt sealcoating is essential in Flagstaff because our climate presents unique challenges that accelerate pavement deterioration. The intense UV radiation at 7,000 feet elevation causes asphalt binders to oxidize rapidly, leading to a loss of flexibility and the appearance of graying. This oxidation makes the asphalt brittle and prone to cracking, which then allows water to penetrate the sub-base, causing further damage through freeze-thaw cycles.
Beyond UV, Flagstaff experiences significant temperature swings and heavy snowfall. Water infiltration from snowmelt and monsoon rains can weaken the asphalt's foundation, leading to potholes and alligator cracking. A properly applied sealcoat creates a waterproof barrier, preventing this moisture from reaching the base layers, which means your pavement remains stable and structurally sound for longer periods.
Investing in sealcoating also offers significant cost savings over time. Regular sealcoating, typically every 2-3 years, can extend the life of your asphalt driveway or parking lot by many years, delaying the need for expensive repairs or complete repaving. It's a proactive maintenance step that protects your investment against the specific environmental stressors found in the Flagstaff area.
We begin by thoroughly cleaning the entire asphalt surface with power blowers, wire brooms, and specialized degreasers to remove dirt, debris, oil stains, and loose aggregate. Proper cleaning ensures optimal adhesion of the sealcoat material.
Existing cracks are cleaned and filled with hot-applied rubberized crack filler, which expands and contracts with the pavement, preventing water penetration. Larger potholes or damaged areas are patched with hot asphalt mix to create a uniform surface.
We apply two coats of commercial-grade sealcoat material, either a refined coal tar emulsion or an asphalt-based emulsion, using professional spray equipment or squeegees. This ensures even coverage and the recommended film thickness for maximum protection.
After application, we establish clear barricades and recommend a minimum 24-48 hour curing period before allowing vehicle traffic. This allows the sealcoat to fully dry and harden, achieving its full protective properties and durability.
