Advantages of Sealcoating and Crack Filling
Sealcoating and crack filling are critical to the durability of your asphalt driveway. These preventive maintenance measures also improve your property’s curb appeal.
Sealing asphalt protects it from water damage, spills, weather elements, and traffic wear. Before applying the sealer, the contractor will first repair surface cracks using a crack sealer.
Experts recommend seal coating new asphalt within the first year of application. However, it is not advisable to seal coat within 90 days of the first application.
The consequences of ignoring sealcoating and crack filling are alligator cracking and potholes, leading to the need for major repairs such as asphalt patching and resurfacing.
Why is Sealcoating important?
Sealcoating is a process where a protective top coating is applied to asphalt paving. As asphalt ages, the binder (bitumen) that keeps the sand and gravel degrades. The leading cause of this degradation is oxidation from the sun rays. However, rain, snow, and chemicals such as car oil also compromise the binder.
The seal coat acts as a barrier preventing the rapid degradation of the binder. It is a liquid compound applied on the surface of asphalt using a brush, sprayer, or squeegee. Typically, seal coating is a service provided by professional asphalt paving maintenance professionals.
If performed correctly and regularly by an experienced contractor, seal coating will extend the life and enhance the appearance of asphalt paving.
