Asphalt sealcoating is an important process in pavement maintenance and is known for its ability to extend the life of asphalt surfaces and improve their appearance. However, for many property owners and managers, the process can bring up a number of questions. Understanding sealcoating is key to making the proper decisions about the maintenance of your pavement. Andersen Asphalt & Striping would like to share some of the most frequently asked questions about asphalt sealcoating.

What is Asphalt Sealcoating?

Sealcoating is the application of a protective coating or layer to an asphalt-based pavement . This coating is designed to shield the pavement from various damaging elements, including water infiltration, oils, UV rays, and the wear and tear of traffic. The sealcoat material is typically a mixture of water, oil, slate, and other additives.

Why is Sealcoating Important for Asphalt Maintenance?

Sealcoating is vital for a number of reasons. For one, it prolongs the lifespan of the pavement by protecting it from natural and man-made elements. Additionally, sealcoating restores the black color of asphalt, enhancing the overall appearance of your property. It can also fill in small voids on the surface of the pavement, reducing exposure to oxygen and UV rays.

How Often Should Asphalt be Sealcoated?

It is generally recommended that asphalt should be sealcoated every 2-3 years. However, this can vary depending on several factors, such as the amount of traffic, the climate in your area, and the condition of the pavement. Regular inspection by a professional can help determine your asphalt sealcoating scheduling needs.

Can Sealcoating Repair Cracks in Asphalt?

Sealcoating is not a repair solution for cracks. Cracks need to be properly filled and repaired before the sealcoating process. Sealcoating can then be applied to protect the surface and prevent future cracking.

What is the Best Weather for Applying Sealcoat?

The ideal conditions for sealcoating are in warm, dry weather. Generally, it is best when the temperature is above 50°F both during the application and for at least 24 hours afterward. This ensures proper curing of the sealcoat material.

How Long Does Sealcoating Last?

A properly applied sealcoat can last between 2 to 3 years, depending on traffic conditions and weather exposure. Regular maintenance can extend the life of your sealcoating.

Is Sealcoating Environmentally Friendly?

The environmental impact of sealcoating depends on the type of sealcoat used. Today, many contractors offer eco-friendly sealcoat options that are low in volatile organic compounds (VOCs) and safer for the environment.

Can I Sealcoat My Asphalt Driveway Myself?

While DIY sealcoating kits are available, professional application is recommended for the best results. Professionals have the right equipment and expertise to apply the sealcoat evenly and effectively.

What Should be Done to Prepare for Sealcoating?

Before sealcoating, the surface should be thoroughly cleaned and any necessary repairs, such as crack filling, should be made. Also, any oil spots should be treated. Ensure the pavement is completely dry before applying the sealcoat.
