The Many Benefits Of Sealcoating

If you own asphalt, either on your personal property or at a business you own, then you should be aware of the benefits of sealcoating. Here is a breakdown of exactly what sealcoating is and how it can help you:

What is sealcoating?

Basically, sealcoating is a liquid which can be added to the surface of asphalt in order to help protect it from UV rays, cracking, and traffic. There are three major types of sealcoating and each has different strengths and weaknesses.

1. Coal Tar

One of the most common and durable varieties of sealcoating is coal tar, which is a water-based product. It is also created from the byproducts of steel manufacture. This means that it is highly resistant to damage caused by gasoline and passing vehicles. Therefore, it is a perfect choice for popular roads, which experience a lot of traffic. It is also excellent for reducing UV damage to the asphalt.

However, it is also a greyish color, which means that it is usually blended with other, darker sealcoats in order to create the ideal black color. 

2. Asphalt Emulsion

One of the major problems with coal tar is that its supply is dwindling faster than it can be created. In order to rectify this, people began to use byproducts of the asphalt creation process as a form of sealcoating, which is known as asphalt emulsion.

Asphalt emulsion is very dark, which makes it a prime candidate for both mixing and darkening your asphalt. However, it's primary drawback is that it is not as protective as other forms. It also does not offer amazing protection against either UV rays or automobile damage.

3. Oil-Based Asphalt

Finally, there is oil-based asphalt, which is generally the least preferable option. Unfortunately, it offers poor protection against petroleum products and leaves a very distinctive odor for several days after application. It can take quite a while to cure and be ready for use, so it's not a good choice for most applications.

How to Apply Sealcoating

Several of the main application methods are: via specialized spraying tools, by hand, or by a moving squeegee machine. Generally, all the methods require that you apply two separate coats with a 1-2 day gap in between. Your choice in method will depend on several key factors, such as whether you are willing to rent expensive equipment, how large the area is that you need to coat, and how much manual labor you are willing to exert. If necessary, hire a professional, like Hals Construction Inc., to help you with your sealcoating.
