Asphalt Parking Lot Sealcoating FAQ

What Is Asphalt Parking Lot Sealcoating?

Sealcoating is the process of applying a protective coating to the surface of asphalt pavement. This coating acts as a barrier against damaging elements such as water, UV rays, vehicle fluids, and oxidation.

Over time, exposure to the environment causes asphalt to dry out, become brittle, and develop cracks. Commercial parking lot sealcoating helps slow this deterioration and keeps pavement in better condition for longer.

Why Is Parking Lot Sealcoating Important?

Asphalt naturally deteriorates as it ages. Without protection, the surface becomes more vulnerable to cracking, potholes, and structural damage.

Sealcoating helps preserve the asphalt by reducing the impact of weather, sunlight, moisture, and chemicals. It also enhances the appearance of the pavement by restoring its rich black color, creating a cleaner and more professional look for customers, tenants, and visitors.

How Often Should a Parking Lot Be Sealcoated?

The ideal sealcoating schedule depends on factors such as traffic volume, weather exposure, and pavement condition. In general, many commercial parking lots benefit from sealcoating every two to three years.

Lots that experience heavy traffic or significant exposure to the elements may require more frequent maintenance. A professional pavement evaluation can help determine the best schedule for your specific property.

Can Sealcoating Repair Cracks and Potholes?

Sealcoating is designed to protect asphalt, not repair major damage. Before sealcoating is applied, cracks and potholes should be properly repaired to create a stable surface.

Crack filling and asphalt repairs are often completed as part of the preparation process. Addressing existing damage before sealcoating helps maximize the effectiveness and longevity of the protective coating.

How Long Does Sealcoating Take to Dry?

Drying times can vary depending on weather conditions, temperature, humidity, and the specific sealcoating material being used. In many cases, parking lots can be reopened to vehicle traffic within 24 to 48 hours.

Property owners should follow the contractor’s recommendations regarding drying and curing times to ensure the best results.

Does Parking Lot Sealcoating Make Financial Sense?

Yes. Sealcoating is one of the most cost-effective forms of pavement maintenance available. By protecting asphalt from premature deterioration, sealcoating can help reduce the need for extensive repairs and delay the expense of parking lot resurfacing or replacement.

Routine maintenance is typically far less expensive than addressing major structural pavement failures later.

When Is the Best Time to Sealcoat a Parking Lot?

Commercial parking lot sealcoating is generally performed during warmer months when temperatures and weather conditions are favorable for proper curing. Spring, summer, and early fall are often ideal times for sealcoating projects in Michigan.

Scheduling maintenance proactively helps ensure your parking lot receives protection before harsh weather conditions take a toll on the pavement.
