Sealcoating is a protective treatment applied to asphalt surfaces, such as driveways, parking lots, and roads, to safeguard them against the damaging effects of sunlight, water, oil, and other elements. This process involves applying a coal tar or asphalt-based emulsion over the surface, forming a protective layer that seals small cracks and prevents moisture penetration. Sealcoating enhances the appearance of the pavement, restores its original black color, and provides a smooth, uniform surface. Additionally, it helps to extend the lifespan of the asphalt by reducing oxidation and minimizing the formation of cracks and potholes. Overall, sealcoating is an essential preventive maintenance measure that preserves and maintains the structural integrity of asphalt surfaces, saving both time and money in the long run.
