Asphalt Sealing A & B Asphalt Maintenance Reasons for Seal Coating: Seal coating is designed to protect and extend the life of your asphalt from the damaging effects of the environment, including moisture and ultraviolet oxidation and everyday wear and tear from vehicular traffic. Protecting your asphalt with seal coating is similar to using sun block on your skin or varnish on wood, meaning that it slows the destructive effects of our environment and everyday life. Seal coating also minimizes raveling (the loss of aggregate) and fills minor voids in the surface. Other benefits include creating a uniform color and improving the curb appeal appearance of your property. Seal coating, followed by re-striping of parking spaces, handicapped areas and crosswalks improves traffic flow and enhances public safety. When and Where to Seal Coat: To reduce long-term maintenance expenses (such as expensive asphalt overlays), industry experts recommend that pavement should be seal coated every two to five years, depending on traffic and overall condition. Other than cosmetic improvement, pavement that exhibits extensive cracking, base failure, or severe surface raveling will not significantly benefit from seal coating. Sealer tends to not adhere well to areas saturated with oil, so such areas must be treated with an oil spot primer to aid adhesion, or cut out and replaced with new asphalt. Sealer is applied by either squeegee or spray methods. The spray method is recommended for smooth pavement, whereas rough, porous surfaces are better serviced by the squeegee method with its thicker application. Normal curing time is 24 hours for moderate temperature and humidity conditions. Scope of Work: Before sealcoating can commence, all vehicles have to be removed from the work area. The job site will normally be barricaded off the night before and residents and employees will be notified of the work the week prior so they can plan accordingly. After the job site has been cordoned off, the asphalt is meticulously cleaned with steel bristle brooms and mechanical blowers to ensure that the sealer will adhere. After the cleaning is complete, a thick coat of sealer is hand squeegeed along the edges of the asphalt; carefully avoiding concrete, decorative rocks and sides of buildings. Once the edge has been squeegeed, the sealer is then applied via spray wand over the entirety of the asphalt. Once the first coat has dried, a second coat is then applied. After the second coat has dried, striping can commence as necessary. To avoid tracking the sealer onto concrete sidewalks or into ones home or business, do not walk or drive on the sealer until 24 hours after the job has been completed.
