This process is crucial for maintaining the structural integrity and appearance of your asphalt, acting as a sacrificial layer that takes the brunt of UV radiation, water, and traffic wear. We ensure proper surface preparation, which is the most critical step, because without it, even the best sealer will not adhere correctly or provide lasting protection.
Our approach begins with a detailed inspection of your asphalt surface to identify any areas requiring pre-treatment, such as oil spots or significant cracks. We then use high-powered blowers and wire brushes to remove all loose debris, dirt, and vegetation, ensuring a clean, porous surface for optimal sealer adhesion. For oil and gas stains, we apply a primer to prevent bleed-through and ensure a uniform finish, which means the sealer cures evenly and lasts longer.
For Missoula properties, sealcoating is particularly important due to the significant temperature fluctuations and freeze-thaw cycles we experience. These conditions cause asphalt to expand and contract, leading to cracks that allow water to penetrate the sub-base, causing further damage. A properly applied sealcoat acts as a barrier, preventing water intrusion and slowing down the oxidation process caused by the intense summer sun and harsh winter elements, thus preserving your asphalt's flexibility.
Many homeowners ask about the best time to sealcoat. We generally recommend waiting at least six to twelve months after new asphalt installation to allow the surface to fully cure and release its oils before applying sealer. After that, a sealcoat application every two to three years is typically sufficient to maintain optimal protection, depending on traffic volume and environmental exposure. We use commercial-grade sealers that offer superior durability and a richer, darker finish.
Missoula's climate presents unique challenges for asphalt pavements, making regular sealcoating a critical maintenance practice. Our hot summers and cold, snowy winters, coupled with significant freeze-thaw cycles, accelerate the degradation of unprotected asphalt. UV radiation from the sun oxidizes the asphalt binder, causing it to become brittle and lose its flexibility, which leads to surface raveling and cracking.
Water penetration is another major concern. When cracks form, water seeps into the asphalt's base layers. During freezing temperatures, this water expands, creating potholes and further damaging the pavement structure. Sealcoating creates a waterproof barrier that prevents this infiltration, protecting the underlying base from erosion and weakening, which means your pavement remains stable and resistant to structural failures.
Beyond protection from the elements, sealcoating also improves the aesthetic appeal of your property. It restores the rich, dark black color of new asphalt, enhancing curb appeal and making your driveway or parking lot look well-maintained. This dark surface also absorbs more solar energy, which can help melt snow and ice slightly faster in winter, a small but noticeable benefit in Missoula.
We begin by thoroughly cleaning the asphalt surface using commercial-grade blowers, wire brushes, and brooms to remove all dirt, debris, and loose aggregate. Any oil or grease spots are treated with a specialized primer to ensure proper adhesion of the sealer.
Minor cracks (typically under 1/4 inch wide) are cleaned and filled with a hot-applied rubberized crack sealant. This prevents water from penetrating the sub-base, which is crucial for the long-term integrity of the pavement.
We apply two coats of commercial-grade asphalt emulsion or refined coal-tar sealer using either spray equipment or squeegees, depending on the surface and desired finish. This ensures a uniform, durable protective layer across the entire surface.
The newly sealed surface is barricaded to prevent traffic for 24-48 hours, allowing the sealer to fully cure and harden. We advise against heavy vehicle traffic for at least 72 hours to ensure maximum durability and longevity of the sealcoat.
