What Are The Advantages Of A Seal Coat?

Asphalt is an inexpensive way to create a driveway for your home, but as tough as it might appear, asphalt is susceptible to the ravages of mother nature. For example, the UV rays of the sun can bake asphalt until it gets brittle and prone to cracking. This is just one of the dangers that asphalt has to contend with. If you want to decrease the cost of maintaining your driveway and extend its service life, you should consider installing a seal coat. 

What Is a Seal Coat?

A seal coat can be made of a few different materials such as coal tar or an asphalt emulsion. It will come as a thick liquid that you paint over your driveway. Not only will a seal coat return your driveway to its original color, but it will help to protect it from the elements and other agents that could cause your driveway to break apart. 

What Are the Benefits of a Seal Coat?

If you do nothing to protect your driveway, it is only a matter of time before cracks and potholes start to form. As mentioned previously, the sun can bake out any liquid in the asphalt tar that holds your driveway together. When this happens, your driveway looses its ability to flex with the pressure of vehicles driving over it. Thus, simply driving your car on a brittle driveway can create enough stress to cause cracks. Water can get down into the smallest cracks and depressions in your driveway, and when that water freezes, it creates a wedge that can create and widen cracks. A final danger is posed by gas and other petroleum products that leak on your driveway and dissolve the asphalt that holds it together. A seal coat will protect your driveway against all of these dangers. 

You should install a seal coat right after you install a new driveway to keep your driveway in good condition, but even if you move into a home that has an old driveway, you can still reap some benefits by applying a seal coat. With older driveways, you will want to repair any damage to the driveway before you apply the seal coat for best results. While you can buy and apply seal coat on your own, you will usually get better results by trusting the job to professionals like Norwest. They will have the right tools and experience to get the job done quickly and correctly.
