What Is Parking Lot Sealcoating? Benefits & Process

Parking lot sealcoating is the process of applying a protective layer over your asphalt parking lot. This layer shields the asphalt from sun, water, and automotive fluids, extending its life and improving its appearance.

Parking lot sealcoating is an essential maintenance practice for any business with an asphalt parking lot in North Alabama. The sun here in Huntsville and surrounding areas can be intense, and the freeze-thaw cycles of winter also take a toll. Sealcoating helps asphalt stand up to these challenges.

What is Parking Lot Sealcoating and Why Does it Matter?

Asphalt paving is made from aggregates held together by a binder: bitumen. Over time, UV rays from the sun and oxidation cause the bitumen to dry out and become brittle. This leads to cracks and potholes. Water penetration then makes these problems worse. Gas and oil leaks from vehicles also break down the asphalt.

Sealcoating creates a barrier against these damaging elements. It slows down the oxidation process and prevents water from seeping into the pavement. It also resists gasoline, oil, and salt, which can degrade the asphalt surface.

Another benefit of parking lot sealcoating is that it restores the rich, black color of the asphalt, giving your property a clean and well-maintained look. This makes a good first impression on customers and clients. A well-maintained parking lot also shows that you care about your property and your business.

The Parking Lot Sealcoating Process

The sealcoating process involves several steps to ensure a long-lasting and effective application.

Preparing the Surface

First, the parking lot must be thoroughly cleaned. This involves removing all dirt, debris, and loose aggregate. We use power blowers, sweepers, and sometimes pressure washers to get the surface as clean as possible. Any oil spots or stains are treated and removed or primed to ensure the sealcoat adheres properly.

Next, any existing cracks or potholes need to be repaired. This is a critical step, as sealcoating will not fix structural damage. Small cracks are typically filled with hot rubberized crack filler, which expands and contracts with the pavement. Larger cracks and potholes require more extensive asphalt repair to ensure a stable base for the sealcoat. We always address these issues before applying the sealcoat to prevent further deterioration.

Applying the Sealcoat

Once the surface is clean and repaired, the sealcoat is applied. We use a commercial-grade asphalt emulsion sealer. This material is designed to penetrate the asphalt surface and provide maximum protection. The sealcoat is applied in thin, even coats.

Depending on the condition of the asphalt and the specific product used, two coats are often applied. Each coat needs time to cure properly before the next one is applied. The amount of drying time depends on humidity, temperature, and sun exposure. In North Alabama's summer heat, drying times can be faster, but it is still important to allow sufficient time for each coat to set.

After the final sealcoat application has dried, if necessary, we can then apply parking lot striping, re-marking parking spaces, arrows, and other directional cues. This ensures the lot is safe and functional for traffic flow.

Factors Affecting Sealcoating Cost

The cost of parking lot sealcoating varies based on several factors. The size of the parking lot is a primary consideration, as larger areas require more material and labor. The current condition of the asphalt also plays a significant role. If there are many cracks or potholes that need repair, that adds to the overall cost.

Accessibility to the parking lot can influence labor costs. If the area is hard to reach or requires significant traffic management, it might take more time. The type of sealcoat material chosen can also affect the price, as some products offer enhanced durability or quicker drying times, but may cost more. Finally, the timing of the project can impact the cost. Scheduling during off-peak hours or seasons to minimize disruption might be more expensive than during regular business hours.
