Have you considered sealing your commercial asphalt parking lot? A parking lot is a valuable asset for any business, but it does not last forever. The lifespan of an asphalt parking lot depends on location, traffic patterns and weather conditions, such as precipitation and temperature.

Why sealcoat your asphalt parking lot?

A sealcoat will protect the top layer of your commercial asphalt parking lot from harmful ultraviolet rays, moisture penetration and oxidation. It is typically done every 3 years in order to maintain a professional-looking business entry while still ensuring that everyone’s safety is taken into consideration due to the sealcoat’s ability to keep potential hazards at bay like potholes on pavement surfaces after rainstorms.

When should you sealcoat your asphalt parking lot?

The summer months are usually the best time of the year to sealcoat your commercial asphalt parking lot because the coating will dry better and quicker in hot temperatures.

Preparation for sealcoating is essential to avoid any further damage to your asphalt. First, sweep the area, removing any debris. Second, it is best to have qualified experts spread the sealcoat material over your asphalt as they have the experience and knowledge of how much to put down and the right sealant to use. A professional will also be able to spot the common signs that your asphalt parking lot requires sealcoating. These common signs include:


When a pavement like asphalt is left to age without any care or attention, it will begin developing hairline cracks that grow wider over time. These cracks might not seem significant at first glance, but they continue to widen until patches of gravel break through crevices causing dangerous driving conditions for anyone using your parking lot.

By noticing hairline cracks early on and treating them with a sealcoat, you can avoid potential costly patchwork repairs, prevent these cracks from widening and save you money in maintenance down the road.


Pothole hazards come from cracks within parking lots that have had little to no maintenance done to them. These flaws lead to personal injury risks as well as costs associated with repairing vehicles, or even having to replace an entire lot due to damage. If left untreated, potholes will continue to grow in size until they’re too big for the average person to fix on their own.

If you take care of your asphalt and properly maintain it with the right sealcoat, it will be a worthwhile investment for the long haul of your business and everyone who visits.

Damage from Sun

The sun is the enemy of asphalt because over time, ultraviolet rays from the sun breakdown oils and other components that make up asphalt. This causes the surface to fade to a light gray color. As the color in asphalt starts to dim, it begins to disintegrate, becoming more susceptible to cracks and potholes. Not only does this make your lot appear unattractive, but it also requires more maintenance.

Sealcoating provides the best protection against the sun’s harmful rays, ensuring your asphalt’s beautiful, shiny black surface remains intact.

Fluid Stains

If your parking lot commonly experiences fluid stains, you should consider having it seal coated to protect the asphalt from these harmful substances. Sealcoating is a liquid that coats and protects the surface of an asphalt’s top layer making it more resistant to petroleum-based fluids such as motor oil or gasoline which can eat away at the protective material on your pavement if left untreated. If this isn’t done, these liquids will spread across any area they come in contact with leaving behind unsightly black streaks and spots along its path.
