Asphalt should be sealed every 2 to 3 years. The open chain provides easy access to weather, salts, and chemicals to attack and disintegrate the asphaltic molecules. When the asphaltic molicules disintegrate, the asphalt in the pavement loses much of its original properties, such binding and waterproofing. If your driveway or parking lot has turned gray, it means the surface has oxidized and is loosing the binder that holds the aggregate together. Seal-Coating extends the life of your asphalt, preserves your investment, increases the value of your property and landscape. BP2 uses Seal Master products for all of their Seal-Coating jobs, and we are capable of getting several different types of Sealcoat according to what the job consists of making it the right product to have at an affordable cost.
