How to Seal Asphalt: Expert Tips for Protecting Your Asphalt Investment

The long-term durability and performance of driveways, parking lots and roadways depends largely on their construction. In fact, one crucial step in the laying process can be the difference between early deterioration and an asphalt surface that stands the test of time: it all comes down to properly sealed asphalt. Let’s explore how to protect your asphalt for years to come—and save yourself time and money along the way. 

Why Seal Your Asphalt?

During its lifetime, your asphalt surface will be exposed to severe weather, UV rays, vehicle fluids and weight that can lead to stains, crumbling, cracks and costly damage. Sealed asphalt actually helps repel water and is more likely to resist the effects of other exposure over time, reducing the need for expensive repairs or total paving replacement. Plus, sealed asphalt typically appears darker—and therefore fresher—than unsealed asphalt for increased curb appeal as an added benefit.

Types of Asphalt Sealants

The type of sealing used to protect your paving depends on a range of factors, including the asphalt’s intended application, the paving material used, surrounding environmental conditions and budgetary limits. Acrylic sealers are most commonly used in residential driveways and provide a low-gloss finish, while solvent-based sealers can provide a high-gloss, oil-resistant finish to your commercial paving. Asphalt emulsion sealers offer cost-effective, environmentally friendly protection, while the less eco-conscious coal tar sealers are designed for ultra durability. Ultimately, the experts at Raleigh Paving can help you determine the best protection for your asphalt.

So, How Do We Seal Our Asphalt Projects?

Sealing should only take place as a final step, so we’ll ensure our paving process meets all your needs before applying that final layer of protection for a smooth, long-lasting finish. Our team will address any paving repair or replacement needs first, as well as remove any dirt or debris, for a flat base. We’ll then apply a sealant based on the aforementioned factors like the asphalt material used, the asphalt’s use and expected traffic and your budget, aiming for an even coating across the entire surface. We’ll then allow for the requisite drying time—anywhere from 1-4 hours, but ideally as much time as possible—before your asphalt is ready to perform.

When Should You Reseal Your Pavement?

Ongoing maintenance of your asphalt is the best way to minimize costly damage. The amount of maintenance required will depend on how much exposure to the elements, heavy traffic and chemicals it receives. Typically, we recommend resealing after 2-4 years of wear, but if you notice signs of deterioration in your asphalt or concrete paving, a new application may be necessary earlier.
