Need To Sealcoat Your Driveway? You Have Three Different Material Choices

If you have an asphalt driveway, you probably already know about some of the many benefits of sealcoating. Sealcoating your driveway on a regular basis will improve the appearance of your driveway and will extend the life of your concrete. However, did you know that you could choose between three different types of material to sealcoat your driveway?

Before you have your driveway sealcoated again, discuss with your contractor which type of material will be used on your driveway:

Most Common: Asphalt Emulsions

The most common material used to sealcoat driveways is asphalt emulsions. Asphalt emulsions are made from a base of crude oil and also include fillers, chemicals and pigments to create the coating.

It is important to note that none of the chemicals used in most asphalt emulsions mixtures are known to irritate humans. This type of seal coating does not have very much of an odor to it and it tends to dry very quickly. 

The only downside to this type of coating is that over time, gas, oil, salt and sunshine can wear away at the coating. 

The Strongest: Coal Tar

Coal tar is made from crude oven tar, which is a typical byproduct of the steel industry. The biggest downside to coal tar sealant is that it produces a strong odor. The strong odor of coal tar has caused it to fall in usage. 

However, coal tar sealcoating does have one really big advantage. Of all the products used to seal asphalt driveways, coal tar stands up the best to exposure to oil, gas, salt and ultraviolet rays. You don't have to sealcoat your driveway as often when you use coal tar. 

The Most Colorful: Acrylics

If you don't want your driveway to be black, and where hoping to make it a little more colorful and distinctive, you can sealcoat your driveway with a special acrylic sealer.

However, if you want more color, be prepared to pay for it. Acrylics sealant tends to be pretty expensive. They are generally used by business and homeowners to give their pavement a unique look. Acrylic sealants stand up okay to environmental elements, but wear down more quickly than coal tar.

The next time you need to have your driveway sealcoated, talk to the contractor you hire about the materials they plan on using. If you don't like strong smells, go with an asphalt emulsion coating. If you want the coating to last for a long time, go with a coal tar coating. Or, if you want to add a little more style to your driveway, spring for acrylic coating.
