Sealcoating is a protective process applied to asphalt surfaces to extend their lifespan and enhance their appearance. It involves spreading a thin layer of coal tar or asphalt-based emulsion over the pavement to shield it from damaging elements like water, oil, UV rays, and oxidation. Over time, exposure to these elements can cause asphalt to crack, fade, and deteriorate. Sealcoating acts as a barrier, preventing moisture from seeping into the surface and slowing the development of cracks and potholes. It also restores the rich black color of the asphalt, giving it a clean, new look. Typically applied every 2–3 years, sealcoating is a cost-effective way to maintain and protect asphalt surfaces.
