Here at Maximum Driveway Care, we use a premium oil-based sealant called Black Mac. Our product was created to rejuvenate asphalt and extend its life. If you notice your driveway is pale or grey this is because the sun and environment have depreciated the oil in your asphalt. Driveways have three main ingredients, sand, gravel, and oil, and when your oil is depreciated the other two ingredients fall apart. That is why there is sand at the bottom of your driveway. To prevent this from happening you need to spray a fresh coat of our sealant on your asphalt. Our product seeps through the asphalt and creates that chemical bond with the gravel, sand, and oil again! If you want to extend your driveways life call today for a FREE quote.
