Seal coating asphalt parking lots is the process of applying a liquid product over an existing asphalt pavement in a manner that seals the surface. Sealers can provide excellent adhesion, flexibility and durability. Sealers protect and renew old, oxidized pavement and provide a new black surface to existing asphalt parking lots, which helps to melt snow and ice faster. The sealer also acts as protective barrier, sealing away harmful elements such as water, oil and sun rays from penetrating the surface that causes cracking and parking lot failures reducing safety and functionality.
