Benefits of Asphalt Sealing

Protection Against Elements

Asphalt sealing provides a protective barrier against the elements that can deteriorate pavement over time. This includes harmful UV rays, rain, snow, and automotive fluids. By sealing your asphalt, you're essentially extending its lifespan and maintaining its appearance.

Enhanced Appearance

Aside from practical benefits, a fresh sealcoat improves the visual appeal of asphalt surfaces, restoring their rich, black finish. This can significantly boost the curb appeal of a residential driveway or the professional look of a commercial parking lot.

Asphalt Sealcoating Process

Preparation Is Key

Proper preparation is paramount. This involves cleaning the asphalt surface thoroughly to remove debris, dirt, and oil spots. Any necessary repairs, such as crack filling, must be completed beforehand to ensure a smooth, uniform coating.

Application Techniques

At Black Diamond Sealcoating, we utilize commercial equipment to apply sealcoating evenly across the surface. This ensures a consistent, durable layer that fully protects and rejuvenates the asphalt.

Timing and Weather Conditions

We also consider timing and weather conditions crucial to the process. Sealcoating requires dry conditions and warmer temperatures to cure properly. Our experience allows us to schedule jobs during optimal conditions, guaranteeing the best outcome for asphalt sealing Portland OR.

Maintenance Tips Following Sealcoating

After sealcoating, it's important to follow a few maintenance tips to extend the life of your asphalt. These include keeping the surface clean, avoiding sharp objects that can damage the sealcoat, and addressing any spills or leaks promptly to prevent staining and deterioration.

Asphalt Sealcoating Process

Is it worth it to seal asphalt driveway?

Absolutely, sealing an asphalt driveway is a cost-effective way to extend its lifespan and enhance its appearance. Think of sealcoating as a protective sunscreen for your driveway. Just as sunscreen shields your skin from harmful UV rays, a quality sealcoat shields your asphalt from the sun, rain, oils, and other damaging agents. Here at Black Diamond Sealcoating, we've seen driveways go from dull and aged to vibrant and protected overnight. It's not just about making your driveway look good for the short term; it's a matter of adding years to its life and preventing costly repairs down the line.

Is it better to spray or roll on asphalt sealer?

The choice between spraying and rolling on asphalt sealer depends on the specific conditions of the project and the desired finish. Spraying can cover large areas quickly and ensure an even application, making it suitable for commercial parking lots and extensive driveways. Rolling, on the other hand, might offer more precision on smaller, intricate surfaces or residential driveways. At Black Diamond Sealcoating, we consider the unique needs of each surface and often employ both techniques to achieve the best result. Ultimately, the goal is a uniform, durable coat that fully protects the asphalt.

How often should asphalt be sealed?

On average, asphalt should be sealed every two to three years, but this can vary based on several factors including climate, usage, and the condition of the pavement. Frequent exposure to heavy rain, snow, and extreme temperatures can degrade asphalt more quickly. Likewise, high traffic areas may need more frequent sealing. At Black Diamond Sealcoating, we perform a thorough assessment of each surface to recommend a maintenance schedule. It's not just about applying a new coat when the old one looks worn; it's about proactive preservation to ensure longevity.

Do you need to wash asphalt before sealing?

Yes, washing the asphalt surface before applying sealer is essential. This cleaning step removes dirt, debris, and oil spots that can prevent the sealcoat from adhering properly. At Black Diamond Sealcoating, we emphasize proper preparation, which includes a comprehensive cleaning process. Skipping this step or doing it haphazardly can lead to uneven coating and reduced durability of the sealant. The goal is to create a clean, receptive surface that allows the sealer to bond seamlessly for maximum protection and longevity.

What are the signs that your asphalt needs sealing?

Signs that your asphalt may need sealing include visible wear, color fading, small cracks, and brittleness. When the rich, dark color of your asphalt starts to turn gray, it's a clear indicator that the surface is beginning to oxidize and deteriorate. Cracks, no matter how small, can quickly become larger issues as water seeps in and freezes during colder months. These signs not only detract from the appearance of your property but also signal that your asphalt is losing its resilience. Addressing these issues early on with sealcoating can prevent more significant damage and extend the life of your asphalt.

Can sealcoating fix existing cracks in asphalt?

Sealcoating is excellent for protecting and prolonging the life of asphalt but it's not a cure-all for existing damage like deep cracks. Before sealcoating, any cracks should be filled and repairs made to ensure a uniform and effective application. At Black Diamond Sealcoating, we assess each surface and address necessary repairs before applying sealer. This preparatory work is crucial as it ensures that the sealcoating can do its job effectively. While sealcoating can make surfaces look brand new and prevent future damages, addressing existing issues is a necessary step in the asphalt maintenance process.
