Why Your Asphalt Driveway Needs A Sealcoat Applied
You can enhance the appearance of your asphalt driveway and reduce the need for repairs by having a sealcoat applied. The coating can be put on a new driveway after the asphalt has had time to cure completely, and then it can be added every few years after that. Here's why sealcoating is beneficial and how it's done.
Why Asphalt Needs A Sealcoat
Asphalt is made of stones and sand that's held together with a binder. Over time, the binder gradually wears down due to sun exposure and chemicals such as gas and oil that leak from your car. A sign the binder is oxidizing from UV exposure is when the driveway starts to fade from its original dark color. Losing the attractive color is just one effect of sun and weather exposure. When the binder wears away, water can leak into the asphalt and cause cracking and potholes as the water freezes and thaws. Water can even leak into the base beneath the asphalt and cause the soil to loosen or shift. These problems are reduced when sealcoating is applied.
How Sealcoating Protects Your Driveway
A sealcoat is a thin layer of protection for your driveway that sacrifices itself to wear and tear so your driveway is protected. The coating repels rain so the water won't seep into the asphalt. It also protects the binder from the sun so it won't oxidize as fast. Sealcoating also provides a shield against damage from oil drips and chemical spills on your driveway. The coating has a dark black color, so it keeps your driveway looking like new. By having the coating applied regularly, you can slow down the aging of the asphalt, reduce repairs needed, and prolong the life of your driveway.
How Sealcoating Is Applied
Sealcoating goes on as a liquid that can be sprayed on or spread with a squeegee. Your driveway is washed first, and minor repairs are made to cracks. Then, the coating is applied and allowed to dry. You should wait until it is cured before you park on your driveway. The length of time you have to wait depends on the weather conditions and outside temperature. The paving installer will tell you when it's safe to park on your driveway again.
By having the sealcoating applied, your driveway will be an attractive component of your property and add to its curb appeal. Plus, you can ward off alligator crumbles and ugly cracking for as long as possible which not only saves money on repairs, it keeps your driveway from becoming an eyesore.
