What You Should Know About Sealcoating

Posted on: 8 February 2018

Sealcoating is a must for any asphalt surface. Asphalt is used in a variety of construction projects, both residential and commercial. Keeping the asphalt in good shape is something that many property owners are concerned with, and sealcoating can help. Whether it's a parking lot or a driveway, periodic sealcoating can add years to the surface's lifespan and keep it looking great. Here are a few things you should know about when it comes to adding a sealcoat to an asphalt surface. 

What It Does

Knowing exactly what sealcoating can do is important. Sealcoating essentially acts as a barrier to the elements. It protects against UV rays, water, and fluids such as oil and gas that can leak from vehicles. Sealcoating not only protects asphalt, but it also improves its appearance. A sealcoat is applied with either a brush, a sprayer or a squeegee. There are three main types of sealcoats including tar-based, asphalt-based, and petroleum-based. A contractor can help determine which one will work best for your surface. While sealcoats are great for adding a layer of protection and improving an asphalt surface's appearance, they are unable to repair cracks on other damage.

It Can Extend A Surface's Lifespan

The additional protection that regular sealcoating can add to an asphalt surface can help extend its lifespan. How long asphalt will last depends on a variety of factors including climate, how much use the surface receives, and how well it is maintained. An asphalt driveway can last anywhere from 12 to 35 years. Sealcoating can help extend an asphalt surface's lifespan by protecting it from the elements. Sealcoating is recommended every 1 to 3 years.

The Cost

Replacing an asphalt driveway, parking lot, or other type of surface can be pricey. Sealcoating can help delay the need for replacement thereby saving money in the long run. The costs of sealcoating vary depending on whether you decide to do it as a do-it-yourself project or hire a professional. The cost of professional sealcoating is around 25 cents per square foot for a driveway and around 20 cents per square foot for a parking lot. Sealcoating is an affordable way to extend the lifespan of an asphalt surface as well as to improve its appearance.

Sealcoating may not be something that you have considered for your asphalt surface, but it does have a variety of benefits. Sealcoating acts as a protective barrier for an asphalt surface. It can extend its lifespan if done every 1 to 3 years. The cost of sealcoating is affordable. Regular sealcoating can also prevent the need for expensive early replacement.
