Asphalt is one of the most common kinds of driveway material. Asphalt is a bitumen product in which petroleum is liquefied and applied to a driveway. When it dries, you need to make sure that you protect it. Since asphalt is a petroleum product, it reacts with other petroleum products. Many of the chemicals that run your car or tractor are petroleum products. If oil drips from your car onto your driveway, that oil can slowly degrade the petroleum in the asphalt. Therefore, you need to protect your driveway. Seal coating is how you protect your driveway from such deterioration.
Coating Your Driveway
Coating your driveway with a seal coating in New Holland, PA protects your driveway from the elements as well as from fluids that could drip from your car. It helps to protect your driveway from cracking as well. A good coat should last you about two years. Such protection means you’ll need to replace your coating every other year.

How to Know
The two-year rule of thumb is just a general rule and not unchanging. Depending on how thick the layer of seal coating was when it was applied and the conditions of your driveway, it could last longer than that. It could also degrade much faster than that. You should look at your driveway’s color to determine when to replace the coat.
Ideally, you will need to wait until the coating has completely worn off before you apply it. If you apply coating before the underlayer wears off, it might not adhere as well as it should. If your driveway is still black, the coating is probably still good. If your driveway has turned gray, the coating has mostly worn off.
