Asphalt is made up of binder, oils, rock, stone, and gravel. The binder holds these components together. When new asphalt is laid it is normal for oils to oxidize out which will make the pavement stronger. Experts suggest sealing your asphalt parking lot 90 days after the asphalt is laid to slow down the oxidation. After the first application of sealer, it is then suggested to seal your asphalt every 2-3 years after that. There are many things that contribute to oxidation: sunlight, rain, air, and chemicals being the most common.
Your parking lot is the welcome mat to your business. After years of exposure to sunlight and the elements asphalt will gradually become a dull grey colour. Applying a fresh coat of sealer will bring your asphalt back to its jet-black finish from when it was initially paved. Asphalt sealing is also a great solution for homeowners who are looking to boost the curb appeal of their home, the matt black finish will make your driveway look as good as new. If you’re looking to list any type of property for sale a fresh coat of asphalt sealer will also help to increase your property value.

Prevents water penetration
Water is to Asphalt what Kryptonite is to Superman. Keeping your asphalt sealed on a regular basis will help to prevent water penetration. A water-based coal tar emulsion sealer will help by filling minor cracks and imperfections in your asphalt. By keeping those imperfections and cracks filled you are lessening the chance of water freezing and expanding inside of them which will make them grow larger year after year.
