Protect your Flagstaff asphalt surfaces from UV damage, water intrusion, and freeze-thaw cycles with our professional sealcoating.
Get Your Free EstimateAsphalt sealcoating is the application of a protective liquid layer, typically a refined coal tar or asphalt emulsion, over an existing asphalt surface. This service includes thorough cleaning of the pavement, addressing minor cracks, and then applying two coats of high-quality sealer to create a durable barrier against environmental stressors. It's a critical maintenance step that revitalizes the appearance of your driveway or parking lot while significantly extending its functional lifespan.
Our approach begins with a detailed assessment of your asphalt's condition. We look for oil stains, minor cracking, and areas of aggregate loss. This initial inspection informs our surface preparation, which is the most crucial part of a lasting sealcoat. We use commercial-grade blowers, wire brushes, and power washers to remove all dirt, debris, and loose aggregate, ensuring optimal adhesion of the sealer.
For Flagstaff properties, sealcoating is particularly important due to the high-altitude sun exposure and significant temperature fluctuations. The intense UV radiation at this elevation accelerates the oxidation of asphalt binders, leading to a faded, brittle surface. Our sealers contain UV inhibitors and create a physical barrier that slows this process, preserving the asphalt's flexibility and dark color. This protection is vital for resisting the freeze-thaw cycles common in Flagstaff winters, which can turn small cracks into major potholes.
Customers often ask about the drying time and traffic readiness. Typically, a sealcoated surface is dry to the touch within 4-8 hours, but we recommend keeping vehicles off for at least 24-48 hours, depending on temperature and humidity. Full curing can take up to 30 days, which means the sealer reaches its maximum hardness and chemical resistance. We advise against harsh cleaning or heavy traffic during this initial curing period to allow the material to properly set.
Asphalt sealcoating is not just about aesthetics; it's a preventative measure against the specific environmental challenges faced by pavements in Flagstaff, AZ. The intense solar radiation at 7,000 feet elevation causes asphalt to oxidize rapidly, leading to the loss of its vital oils and flexibility. This results in a faded, gray appearance and increased brittleness, making the pavement susceptible to cracking.
The significant temperature swings between day and night, coupled with Flagstaff's winter snow and ice, create constant expansion and contraction stresses on asphalt. Water penetration into unsealed cracks, followed by freezing, can cause significant damage through the freeze-thaw cycle, leading to alligator cracking and potholes. Sealcoating forms a waterproof barrier, preventing this water ingress and protecting the sub-base.
Furthermore, sealcoating provides resistance to oil and gas spills, which can dissolve asphalt binders and create soft spots. By applying a protective layer, we help maintain the structural integrity of your pavement, reducing the need for costly repairs and extending its service life by several years. It's an investment that pays off by preserving your property's value and curb appeal.
We begin by thoroughly cleaning the entire asphalt surface using commercial-grade blowers, stiff wire brushes, and, if necessary, power washing. All oil spots are pre-treated with an oil spot primer to ensure proper adhesion of the sealer.
Existing cracks are cleaned and filled with a hot-applied rubberized crack sealant, preventing water penetration. We address minor surface imperfections to create a smoother, more uniform base for the sealcoat.
Two even coats of commercial-grade asphalt emulsion or refined coal tar sealer are applied, either by spray or brush, depending on the specific surface and desired finish. This dual application ensures maximum coverage and durability.
The sealcoated area is barricaded or taped off to prevent premature traffic. We advise a minimum of 24-48 hours for vehicle traffic, with full curing taking up to 30 days for optimal performance and longevity.
