If you have asphalt at your retail business, shopping mall, apartment and condominium community, industrial park, school, airport, or other location, it is important to maintain the asphalt to make it last as long as possible, especially since you have already invested so much money into the initial paving. One critical part of the maintenance program is sealcoating the asphalt. Sealcoating acts as a barrier against materials like oil and gasoline that can react with the surface of the asphalt and damage it. It also can prevent oxidation, guard against cracking, protect against the harsh ultraviolet rays of the sun, and increase the curb appeal of the property by making the pavement surface look like new.
