9 Crucial Steps To Take Before Applying Asphalt Seal Coating

When it comes to maintaining and preserving your asphalt surfaces, a good seal coat is much like a shield. It protects your driveway or parking lot from the ravages of sun, rain, and chemicals. Before you get , there are essential steps to take to prepare your asphalt for this protective treatment. Doing it right extends the life of your pavement and enhances its appearance, making the investment well worth it.

Laying The Foundation With Asphalt Seal Coating Services Bellevue WA:

Did you know that dirt and debris on your asphalt can significantly hinder the effectiveness of seal coating? Before anything else, a thorough cleaning is crucial. This means sweeping away all loose dirt, leaves, and debris. For those stubborn oil stains, a degreaser or detergent will work wonders. It's also a smart move to pressure wash the area to ensure it's immaculately clean. This initial step is foundational; any sealant applied to a dirty surface won't adhere properly, which can lead to patchy areas and reduced longevity of the coat.

Crack Filling: The Art of Asphalt Care

No one likes cracks on their roads—literally! Before seal coating, addressing any cracks in the asphalt is essential. This involves using a crack filler to seal these gaps, preventing water from seeping under the asphalt. Water intrusion is a major enemy of asphalt, leading to further damage like potholes or base erosion. Properly filled cracks ensure a smooth, uniform seal coat, and importantly, it stops small problems from becoming costly headaches in the future.

Oil Spot Treatment: A Necessary Precaution

Here’s a pro tip: don’t overlook those oily patches on your asphalt. Applying sealant directly over oil spots is a recipe for failure. These areas need special attention with an oil spot primer. This primer acts as a barrier, ensuring the seal coat adheres uniformly across the surface. Skipping this step can result in peeling or flaking of the seal coat, compromising the aesthetic and protective qualities of your pavement.

Trim And Tidy: Edges And Obstacles

Seal coating is not just about slapping on some product over your driveway or parking lot. It's about precision and attention to detail. This includes trimming grass along the edges and removing any obstacles that might hinder the application process. Clean edges not only look better, but they also prevent premature wear and tear along the borders of your asphalt.

Weather Watching: Timing Is Everything

Lastly, keep an eye on the forecast. Seal coating requires a dry, warm climate to cure properly. Typically, a 24-hour window without rain post-application is ideal. Also, temperatures should ideally be above 50 degrees Fahrenheit. Applying sealant in less-than-ideal conditions can significantly affect its durability and effectiveness. So, choosing the right day makes all the difference.

Material Choice: Selecting The Best Sealant

Choosing the right sealant can make a significant difference in how well your asphalt withstands the elements and traffic wear. Not all sealants are created equal; they vary based on the type of asphalt, traffic volume, and climatic conditions. For residential driveways, a coal tar emulsion might be ideal due to its durability and resistance to fuel spills. Meanwhile, for high-traffic areas like commercial parking lots, an asphalt-based sealant could offer better flexibility and adhesion. So, opt for driveway sealing services in Bellevue WA, tailored to your specific needs, ensuring that the material chosen will provide optimum protection and longevity for your pavement.

Barrier Installation: Ensuring Uninterrupted Application

Before the sealant application begins, setting up barriers is essential to prevent cars, pedestrians, or pets from accessing the area. This step is crucial as foot or vehicle traffic can disrupt the even laying of the sealant and affect its curing time. Use cones, tape, or signs to create clear boundaries around the work area. Moreover, asphalt sealing services in Bellevue WA, not only help achieve a smooth, flawless finish but also ensure the safety of everyone around. Proper planning and barrier installation make the seal coating process efficient and prevent any unnecessary rework due to disturbances.

The Right Application Method: Sprayer VS. Squeegee

The application method can greatly impact the quality of your seal coating. Using a sprayer is a popular method, as it allows for quick and even coverage, making it ideal for larger areas. The sprayer method also tends to be less labor-intensive. However, for areas that require more precision or where thicker coats are needed, a squeegee might be the better choice. It provides greater control over the thickness of the application and ensures better penetration into the asphalt's pores. Some situations might benefit from a combination of both techniques to maximize the effectiveness of the seal coat. Hire experienced experts to get asphalt sealing in Bellevue WA, and can advise on the best method for your specific situation.

Post-Application Care: The Final Step

After putting on the seal covering, you can't just wait for it to dry. If you take the right steps after applying your seal coat, it will last a lot longer. Do not drive or walk in the freshly treated area for at least 24 to 48 hours so that it has time to cure properly. Keep the area clean and free of anything else during this time. Following the curing process, normal upkeep should include cleaning on a regular basis and limiting exposure to heavy chemicals or oil leaks. Following this maintenance plan will not only keep your asphalt looking good but also keep it working well. This will protect your investment over the years.


When it’s time to protect and preserve your asphalt surfaces, taking the right preparatory steps before applying the seal coat ensures the best outcome. Whether it's a driveway or a parking lot, following these guidelines not only enhances the longevity of your pavement but also its overall look.
