If you’re responsible for an asphalt parking lot, seal coating is one of the most effective ways to prolong its life span, reduce the risk of damage from inclement weather or harsh chemicals, and maintain the overall appearance of the pavement. However, sealants don’t last forever, and sealing too often can lead to peeling and hairline cracks. Here’s what you need to know about protecting your asphalt so it looks pristine year-round.

When Is the Best Time to Redo a Seal Coating?

Initial Coat

The ideal time to have professionals apply an initial coat is one to two years after the parking lot’s first paving or repavement. This is because the seal coating material binds to the asphalt and cement on the surface. If you wait too long, the parking lot may have worn down too much for the sealant to work effectively. If your asphalt is over five years old and you haven’t applied a seal coating, ask a professional contractor whether or not repavement is necessary before adding a sealant.

Resealing Schedule 

Once you have added a seal coating to your asphalt, resealing should be performed four years later, and, subsequently, every four to five years. This pavement maintenance routine will keep your parking lot in shape for longer and ensure it looks beautiful year-round.

Exceptions

The amount you have to reseal may depend on your lot’s location. For example, pavement may need to be sealed more frequently in a lot that receives heavy foot traffic, such as at a shopping center or movie theater. A parking lot in this location should be reevaluated every three years. However, if your lot is used less frequently, it’s more cost-effective to hold off on resealing until five years have passed.
