This process includes thorough cleaning of the surface, filling minor cracks, and then applying a commercial-grade coal tar or asphalt emulsion sealer. The result is a revitalized surface that resists degradation, maintaining its structural integrity and aesthetic for years.
Our approach to sealcoating begins with a detailed assessment of your pavement's condition to determine the most effective treatment. We use industrial-grade blowers and wire brushes to remove all debris, oil spots, and loose aggregate. Any cracks up to 1/2 inch wide are cleaned and filled with hot-applied crack filler, preventing water penetration and further deterioration before the sealer is applied. This preparation ensures maximum adhesion and a uniform, long-lasting finish.
For Portland properties, sealcoating is a critical maintenance step due to the region's specific climate challenges. Frequent rain and freeze-thaw cycles can accelerate asphalt degradation, leading to potholes and surface erosion. Our sealcoating applications are formulated to withstand these conditions, providing a robust shield against moisture intrusion and temperature fluctuations. This proactive maintenance significantly extends the life of your asphalt, delaying the need for costly repaving.
Property owners often ask about the drying time and usability after sealcoating. Typically, the sealed surface is dry to the touch within 4-8 hours, depending on temperature and humidity. We advise keeping vehicles off the freshly sealed area for a minimum of 24 hours, and ideally 48 hours, to allow for full curing and to prevent tire marks. This ensures the protective layer bonds properly and delivers its full intended benefit.
Portland's climate, characterized by significant rainfall and fluctuating temperatures, creates specific challenges for asphalt pavement. Unprotected asphalt is highly susceptible to water penetration, which, combined with the region's freeze-thaw cycles, leads to accelerated cracking and pothole formation. Sealcoating acts as a waterproof barrier, preventing moisture from seeping into the sub-base and causing structural damage.
Beyond water protection, the persistent cloud cover and occasional intense UV exposure in the Pacific Northwest also contribute to asphalt oxidation. This process causes the asphalt binder to dry out, making the pavement brittle and prone to aggregate loss. A high-quality sealcoat contains UV inhibitors that block these damaging rays, preserving the asphalt's flexibility and dark color, which in turn helps it absorb heat more efficiently for snow and ice melt.
Investing in sealcoating every 2-3 years directly translates into significant cost savings over the lifespan of your pavement. By mitigating the effects of weather and oxidation, you effectively double the functional life of your asphalt driveway or parking lot. This preventative measure avoids the substantial expense and disruption associated with major repairs or full asphalt replacement, delivering a superior return on your property maintenance budget.
We meticulously clean the entire asphalt surface using commercial-grade power blowers, wire brushes, and brooms to remove all dirt, debris, and loose aggregate. Any oil or grease stains are pre-treated and removed to ensure proper sealer adhesion.
All cracks up to 1/2 inch wide are cleaned and filled with a hot-applied, rubberized crack sealant. This prevents water intrusion into the sub-base, stopping further deterioration and extending the pavement's life before sealing.
Using specialized spray equipment or squeegees, we apply two coats of commercial-grade asphalt emulsion sealer evenly across the entire surface. This ensures complete coverage and a durable, protective layer that resists wear and tear.
The freshly sealed area is barricaded to prevent traffic for a minimum of 24-48 hours, allowing the sealer to fully cure. This step is crucial for the longevity and performance of the sealcoat, ensuring maximum protection.
