Sealcoating is the first line of defense in protecting your asphalt investment. Many factors contribute to the deterioration of asphalt, such as sun exposure, water erosion, oxidation, chemicals, freeze-thaw cycles and traffic. WNY applies all sealcoat emulsion by hand (even large commercial lots) to the surface of the pavement. This application, as opposed to "spray on" applications, goes on thicker and therefore lasts longer. In addition to protecting the asphalt, sealcoating also has esthetic value. Freshening your asphalt with a rich black color definitely adds curb-side appeal.
