The Sealcoating Process for Asphalt – A Guide

30 August 2023 by Clifton Sullivan

Asphalt is the most commonly used material for driveways and parking lots in the United States. Nevertheless, lacking adequate upkeep, it can rapidly degrade as a result of exposure to sunlight, rain, and other weather elements. Sealcoating is an essential process for protecting your asphalt surface from damaging factors and extending its lifespan. This guide will go over some things you need to know about the sealcoating process.

What is Sealcoating, and Why is it Necessary?

Sealcoating serves as a shield, safeguarding your asphalt surface from harmful elements like UV rays and water. The process involves applying a coal-tar or asphalt-based emulsion to the surface, which fills in small cracks and prevents water from seeping through and causing further damage. Sealcoating also enhances the look of your asphalt surface by reestablishing its rich, dark hue, giving it a fresh and pristine appearance.

When is the Right Time to Apply Sealcoat?

The best time to apply a sealcoat is several months after installing your asphalt surface and then every few years after the initial coat. However, the timeline may vary depending on the amount of traffic your surface receives, the weather conditions, and the quality of the initial installation. If you notice cracks or fading, then it's time to apply a new layer of sealcoat.

Can You DIY the Sealcoating Process?

Although you can purchase sealcoat and attempt to apply it yourself, it's highly recommended to hire a professional contractor for the job. A professional contractor has the proper equipment and experience to ensure that the application process is done correctly. They'll also do a thorough cleaning and inspection of your asphalt surface before applying the sealcoat to ensure that it's in good condition.

What's the Cost of Sealcoating an Asphalt Surface?

The cost of sealcoating an asphalt surface varies depending on several factors, such as the size of the surface, the quality of the sealant, and geographic location. On average, expect to pay a fraction of a dollar per square foot for sealcoating. You can save some money by doing some pre-sealcoating preparation work, such as filling small cracks with sealant before the contractor arrives.

What to Expect During the Sealcoating Process

The sealcoating process typically takes around a day, depending on the size of the surface, to be sealed. Here's what you can expect:

• Clearing and cleaning the surface of debris, dirt, and oil
• Filling any visible cracks with a crack filler
• Applying a first coat of sealer, followed by a second coat once the first coat has dried
• Applying a final layer of sand to add texture and improve skid resistance

Sealcoating is a crucial aspect of maintaining your asphalt surface and ensuring its longevity, and it's worth the investment. Hiring a professional contractor will save you time and ensure that the job is done properly. With proper sealcoating and regular maintenance, your asphalt surface will maintain its appearance and functionality for many years to come.
