It is crucial to apply a seal coat to an asphalt driveway in order to protect the pavement. However, you may quickly discover that there are multiple types of sealants available, which can make you wonder if you are picking the right one. Here are a few key differences between the various types of asphalt sealants.
Coal-tar-based sealants are commonly used on asphalt due to how it allows the surface to resist gasoline and oil spills. They do a great job at providing protection against the UV rays from the sun as well, which prevents asphalt from prematurely drying out and deteriorating over time.
However, know that coal-tar-based sealants contain a substance known as polycyclic aromatic hydrocarbons, which can potentially harm the environment. There may be a ban where you live on using a coal-tar-based sealant because of this, which will force you to pick another for your asphalt driveway.
A popular alternative when coal-tar-based sealants cannot be used are asphalt-based sealants. They offer many of the same protections in terms of durability that other sealants provide, as well as being an environmentally friendly option. An asphalt-based sealant is made by blending together asphalt with various additives and water, which provides a protective barrier that is simple to apply on your own.
A newer option for asphalt sealant is acrylic-based material. They are known for providing longevity to your asphalt since it resists water damage, harsh weather conditions, and UV rays quite well. An acrylic-based sealant can also make the surface look smooth and glossy, which actually enhances the look of your asphalt driveway in a way that other sealants do not.
A problem with an acrylic-based sealant is that it does not resist the damage caused by oil and gas as well. While a car does not regularly leak these fluids, it may not be a concern to you if you do not care about your driveway looking perfect.
As you can tell, there is a bit of thought that goes into picking the right asphalt sealant for your driveway. Carefully consider what you are trying to accomplish with a sealant to determine the one that fits your needs the best. Know that you can always hire a professional to come out and do the job for you since they can share their expertise in selecting the right coating to get the job done.
