During the winter thaw, the store bought sealants can chip, peel or flake off leaving your driveway unprotected and susceptible to cracks.
Black Mac is a petroleum/oil based product which is the very substance asphalt is made from. When applied to your driveway by a high pressure sprayer, it does just paint the top. Instead, the sealer penetrates the surface going deep into your asphalt. This protect against the sun's harmful U.V.B. rays and restores colour and aesthetics thus extending the life of your driveway and saving you money!
