A Primer on Asphalt Sealcoating

Using an asphalt sealer in Pittsburgh, PA, can enhance the durability and longevity of your pavement. Whether it’s for the parking lot or the roads, sealcoating should be a part of your property’s maintenance program. In this article, we will discuss the basics of sealcoating and how it benefits pavement.

How Sealcoating Works

The basic components of asphalt pavement are rock, gravel, and a binder. The binder is perhaps the most important portion of the three since it keeps the pavement together. The pavement is porous, which means it can absorb water, oils, and other liquid contaminants over time. As a consequence, they can degrade the binder material and increase the chance of damage to the pavement.

Asphalt sealer, also known as sealcoat, provides a layer of protection to pavement. The sealcoating blocks water, oils, and also UV damage. It can also create a slip-resistant surface. Sealcoating can be applied via brushing, spray, or squeegee. It normally leaves a deep, black finish.

 

Asphalt sealer is particularly useful as it can potentially double the effective lifespan of pavement. This means that property owners can save thousands of dollars by adhering to a maintenance routine rather than investing in a costly re-pavement project every few years.

Sealcoating is a vital component of the maintenance process. It is highly recommended to apply an asphalt sealer every two to three years.
