Sealcoat

Sealcoat is a bituminous liquid mixture that is applied to asphalt.

Benefits

Since asphalt is a petroleum based product, other petroleum products may react with the surface. This includes vehicle oil and gasoline. The sealcoat may act as a temporary barrier against those materials. A sealcoat is not a crack filling agent; this must be done prior to applying the sealcoat. sealcoating may reduce the friction or anti-skid properties associated with the exposed aggregates in asphalt.

Types

There are primarily three types of asphalt sealers. They are commonly known as coal-tar, asphalt emulsions, and acrylics. All three have their advantages but are typically chosen by the contractors’ preference unless otherwise specified. Some States in North America have banned the use of coal tar based sealants primarily based on United States Geological Survey studies.

Acrylic sealers are typically produced in multiple colors and are a niche product for sealing and beautifying properties such as driveways, golf cart paths or as identifiers to specific parking areas or entrances.
