Sealcoating is the process of applying a protective liquid coating over an existing asphalt driveway to shield the surface from water penetration, UV ray damage, oil and chemical spills, and general weathering that breaks down blacktop over time. The sealcoat material — typically a coal tar or asphalt-based emulsion — is brushed or sprayed evenly across the driveway surface, filling in small surface cracks and restoring the rich, dark appearance of fresh asphalt. Think of driveway sealcoating as a protective barrier that sits between your asphalt and the elements, slowing down the oxidation and deterioration process that causes driveways to fade, crack, and crumble. At L&C Blacktop, we use professional-grade sealcoating products and proper application techniques to give your driveway the protection it needs to stay looking great and performing well for years to come.
