When Is The Best Time To Apply Oil Based Sealcoating On A Parking Lot?

February 26, 2024

When it comes to maintaining a parking lot, applying sealcoating is an essential step to protect the asphalt surface from damage caused by water, sunlight, and heavy traffic. One of the key decisions that needs to be made when planning to sealcoat a parking lot is whether to use oil-based or water-based sealcoating. In this blog post, we will focus specifically on oil-based sealcoating and discuss the best time to apply it for optimal results.

Understanding Oil-Based Sealcoating

Oil-based sealcoating is a popular choice for parking lot maintenance due to its durability and ability to provide a long-lasting protective layer to the asphalt surface. This type of sealcoating is made from a mixture of asphalt, additives, and emulsifiers that create a flexible and weather-resistant coating. Oil-based sealcoating is known for its deep black finish and ability to protect the asphalt surface from UV rays, water penetration, and chemical damage.

Factors to Consider

Before deciding on the best time to apply oil-based sealcoating to a parking lot, it is important to consider a few key factors that can impact the effectiveness of the sealcoating application. These factors include weather conditions, temperature, traffic volume, and the condition of the asphalt surface.

Best Time to Apply Oil-Based Sealcoating

Ideally, the best time to apply oil-based sealcoating on a parking lot is during the warmer months of the year when the temperature is consistently above 50 degrees Fahrenheit. This temperature range allows the sealcoating to cure properly and form a strong bond with the asphalt surface. Applying sealcoating in cooler temperatures can lead to longer curing times and may affect the overall performance of the sealcoating.

Spring and summer are typically the most ideal seasons to apply oil-based sealcoating, as the warmer temperatures and longer daylight hours provide the optimal conditions for the sealcoating to cure properly. It is important to avoid applying sealcoating during rainy or humid weather, as moisture can affect the adhesion and drying of the sealcoating.

Preparing the Surface

Before applying oil-based sealcoating to a parking lot, it is essential to properly prepare the surface to ensure a smooth and even application. This includes cleaning the parking lot surface to remove dirt, debris, and oil stains, as well as filling any cracks or potholes to prevent water infiltration. It is also important to trim any vegetation along the edges of the parking lot to create a clean and defined boundary for the sealcoating application.

Application Process

The application process for oil-based sealcoating involves cleaning the surface, applying the sealcoat with a squeegee or sprayer, and allowing the sealcoating to cure for at least 24 hours before reopening the parking lot to traffic. It is important to follow the manufacturer’s instructions for mixing and applying the sealcoat to ensure a proper and effective sealcoating application.

Benefits of Oil-Based Sealcoating

There are several benefits to using oil-based sealcoating on a parking lot, including:

– Provides a protective barrier against UV rays, water, and harsh weather conditions

– Enhances the appearance of the asphalt surface with a deep black finish

– Extends the lifespan of the asphalt by preventing cracks, potholes, and deterioration

– Improves traction and safety for vehicles and pedestrians

Summary

The best time to apply oil-based sealcoating on a parking lot is during the warmer months of the year when the temperature is consistently above 50 degrees Fahrenheit. It is important to consider weather conditions, temperature, traffic volume, and the condition of the asphalt surface when planning for a sealcoating application. By following the proper preparation and application process, oil-based sealcoating can provide long-lasting protection and enhance the appearance of a parking lot. If you are considering sealcoating your parking lot, it is recommended to consult with a professional contractor to ensure a successful and effective sealcoating application.
