Seal coat application is a crucial step in maintaining the longevity and appearance of asphalt surfaces. Whether it’s a driveway, parking lot, or road, seal coating provides a protective layer that shields the asphalt from the damaging effects of weather, UV rays, and traffic. In this article, we will guide you through the step-by-step process of seal coat application, ensuring optimal results for your asphalt surfaces.


Before starting the seal coat application, it is essential to prepare the surface properly. This includes cleaning the area thoroughly, removing any debris, dirt, or vegetation that may hinder the bonding of the seal coat. Use a broom, blower, or power washer to ensure a clean surface.

Repairs and Patching

Inspect the surface for any cracks, potholes, or other damages. It’s crucial to repair these issues before applying the seal coat. Use a suitable asphalt repair material to fill the cracks and patch any damaged areas. Allow sufficient time for the repairs to cure before proceeding to the next step.

Edging and Taping

To prevent accidental overspray and ensure clean edges, it’s recommended to tape off any adjacent surfaces like curbs, sidewalks, or landscaping. Use painter’s tape or a similar masking material to create a boundary between the asphalt and the surrounding areas.

Mixing the Seal Coat

Properly mix the seal coat material using a paddle mixer or agitator. Follow the manufacturer’s instructions for the correct mixing ratios and procedures. It’s essential to achieve a homogeneous mixture to ensure consistent results.


Start the application process by pouring the seal coat material onto the surface. Use a squeegee, brush, or spray system to evenly distribute the seal coat. Work in small sections, applying a thin and uniform layer. Avoid over-application, as it can lead to drying issues and an uneven finish.

Curing and Drying

Allow the seal coat to cure and dry according to the manufacturer’s recommendations. This typically involves avoiding foot or vehicle traffic for a specified period. Proper curing ensures the seal coat forms a strong bond with the asphalt surface, maximizing its effectiveness.

Finishing Touches

After the seal coat has dried, remove the tape and inspect the surface for any missed spots or imperfections. Touch up these areas as necessary to ensure a seamless and professional-looking finish. Properly dispose of any leftover materials and clean the application tools.


By following these step-by-step instructions, you can achieve optimal results when applying Seal Coat to your asphalt surfaces. Remember to prioritize preparation, repairs, and proper application techniques to extend the lifespan of your asphalt, enhance its appearance, and protect it from the elements.
