Asphalt Sealcoating

What is sealcoating?

Sealcoating protects asphalt from the damaging effects of the environment, including moisture and ultraviolet oxidation, while restoring color and uniformity. It also minimizes raveling (the loss of aggregate) and fills minor voids in the surface to maintain safety.

How often do I need to sealcoat?

New asphalt should be sealed 9-12 months after installation. Sealcoat should then be applied every two to three years, depending on traffic volume and overall condition of the asphalt.

Can all asphalt be sealcoated?

Not all asphalt should be sealcoated. Pavements that exhibit extensive alligator cracking, base failure, or severe surface oxidation will not significantly benefit from sealcoating. To ensure proper adhesion, your asphalt surface should be evaluated prior to an application of sealcoat.

How long does sealcoating take?

Normal curing time for sealcoat is 24 hours for moderate temperature and humidity conditions.
