Benefits of Sealcoating

Sealcoat or pavement sealer is a coating for asphalt-based pavements. The top of the asphalt pavement is said to oxidize and decay when left unprotected. The sealcoat serves as the asphalt’s protective barrier against wear, freezing, and vehicle leaks. Sealcoat is marketed as a protective coating that extends the life of asphalt pavements.

Sealcoating may also reduce the friction or anti-skid properties associated with the exposed aggregates in asphalt.


Prior to application the surface must be completely clean and dry using sweeping methods and/or blowers. If the surface is not clean and dry, then poor adhesion will result. Pavement sealers are applied with either pressurized spray equipment, or brushed or squeegeed by hand. Equipment must have continuous agitation to maintain consistency of the sealcoat mix.
