Sealcoating is a protective coating applied to asphalt-based pavements to shield them from the damaging effects of elements such as water, oils, and UV damage. This preventative maintenance process involves the application of either coal tar pitch or asphalt cement mixed with inert fillers, water, emulsifying agents, or additives. The sealcoat acts as a barrier against these elements, greatly extending the pavement's lifespan by preventing oxidation, which can lead to cracks and potholes over time.

The process of sealcoating not only protects but also enhances the appearance of the pavement, giving it a dark, rich, new look that improves the overall aesthetics of the area. This is particularly beneficial for commercial properties where the appearance can impact customer perceptions. Sealcoating is typically recommended every two to three years to maintain the integrity and aesthetics of pavement surfaces. It is most effective when the underlying pavement is in relatively good condition without major cracks or structural issues.

Furthermore, sealcoating is cost-effective, as it is much cheaper than having to repair or replace damaged asphalt. By forming a protective layer, it minimizes the need for more frequent and costly repairs, making it a wise investment for both private driveway owners and municipalities managing extensive road networks. Additionally, because it can be quickly applied and dries within hours, sealcoating projects usually have minimal impact on traffic and can be scheduled to accommodate various logistical considerations.
