This process includes thorough cleaning of the surface, crack filling, oil spot priming, and then one or two coats of a high-quality sealant, designed to protect the asphalt binder from oxidation and water intrusion.
Our approach begins with a detailed assessment of your pavement's condition. We identify existing cracks, oil stains, and areas of wear, which dictates our preparation strategy. For instance, cracks wider than 1/8 inch are cleaned and filled with hot-applied or cold-pour crack filler, depending on their size and movement, because untreated cracks allow water to penetrate the sub-base, leading to accelerated deterioration.
In Billings, our sealcoating process is particularly critical due to the region's freeze-thaw cycles and intense summer sun. The temperature fluctuations cause asphalt to expand and contract, creating stress that leads to cracking. A properly applied sealcoat acts as a barrier, minimizing water absorption into these cracks and slowing down the oxidation caused by UV radiation, which means your pavement remains flexible and structurally sound for longer.
Many property owners in Billings wonder about the best time to sealcoat. Generally, we recommend sealcoating asphalt that is at least six months old and ideally between one and three years old, then every 2-3 years thereafter. This schedule provides optimal protection without over-applying material, which can lead to premature flaking or delamination. We also advise against sealcoating during periods of heavy rain or when temperatures are expected to drop below 50°F within 24 hours of application, as this can compromise the sealer's cure and adhesion.
We use commercial-grade, polymer-modified asphalt emulsions that offer superior flexibility and adhesion compared to standard sealers. These materials are engineered to withstand Billings' specific environmental challenges, providing a tougher, longer-lasting finish. After application, we recommend allowing 24-48 hours for vehicle traffic, depending on ambient temperatures and humidity, to ensure the sealer fully cures and achieves maximum durability.
Asphalt sealcoating is not just about aesthetics; it's a vital maintenance practice that protects your investment against Billings' unique climate challenges. The intense UV radiation from our high-altitude sun accelerates the oxidation of asphalt binders, causing the pavement to become brittle, fade to gray, and develop surface cracks. A sealcoat provides a sacrificial layer that absorbs this UV damage, preserving the integrity of the underlying asphalt.
Billings experiences significant temperature swings, from scorching summers to freezing winters, accompanied by freeze-thaw cycles. Water is asphalt's worst enemy; when it penetrates cracks and then freezes, it expands, creating larger cracks and potholes. Sealcoating fills hairline cracks and creates a water-resistant barrier, preventing water intrusion and mitigating the damage caused by these cycles, which means fewer costly repairs down the line.
Beyond weather protection, sealcoating defends against chemical spills like oil, gas, and antifreeze, which degrade asphalt binders on contact. It also enhances the pavement's curb appeal, restoring its rich black color and making it easier to clean. This combination of protection and aesthetic improvement significantly extends the service life of your driveway or parking lot, providing a better return on your pavement investment in Billings.
We begin by thoroughly cleaning the asphalt surface using power blowers, wire brooms, and edgers to remove all loose debris, dirt, and vegetation. Any oil or grease stains are then pre-treated with a specialized primer to ensure proper adhesion of the sealcoat.
Existing cracks are addressed next. Cracks 1/8 inch or wider are cleaned out and filled with a hot-applied rubberized crack sealant or a cold-pour asphalt emulsion filler, depending on crack size and type, to prevent water penetration and sub-base erosion.
Using commercial spray applicators or squeegees, we apply one or two coats of a high-quality, polymer-modified asphalt emulsion sealer. This ensures uniform coverage and proper mil thickness for maximum protection and a consistent finish.
After application, the sealed area is barricaded to prevent premature traffic. The sealcoat typically requires 24-48 hours to cure sufficiently for vehicle traffic, with full curing taking several weeks, ensuring optimal durability and longevity.
