Sealcoating vs. Resurfacing: What’s the Difference?

What Is Sealcoating?

Sealcoating is a preventative maintenance treatment applied to the surface of an asphalt parking lot. The sealcoat acts as a protective barrier against damaging elements such as UV rays, rain, snow, ice, vehicle fluids, and oxidation.

Over time, exposure to the elements causes asphalt to become dry, brittle, and faded. A fresh sealcoat restores the rich black appearance of the pavement while helping prevent premature deterioration. Parking lot sealcoating is typically recommended every two to three years, depending on traffic levels and environmental conditions.

It is important to understand that sealcoating does not repair structural damage. Instead, it helps preserve asphalt that is still in relatively good condition by slowing the aging process and reducing future maintenance costs.

What Is Asphalt Resurfacing?

Asphalt resurfacing is a more extensive repair solution used when a parking lot has significant wear and surface damage. During the resurfacing process, the top layer of pavement is removed and replaced with a fresh layer of asphalt.

Resurfacing addresses issues such as widespread cracking, surface deterioration, minor depressions, and general aging. The result is a smooth, like-new driving surface without the cost of a complete parking lot replacement.

Because resurfacing adds new asphalt, it restores both appearance and functionality. However, the underlying foundation must still be structurally sound. If the base has failed, a full replacement may be necessary instead.

When Should You Choose Sealcoating?

Sealcoating is the ideal option when your parking lot is showing signs of normal aging but remains structurally healthy.

You may be a good candidate for sealcoating if your pavement has:

• Minor surface wear
• Fading or discoloration
• Small, repaired cracks
• No major potholes or structural issues

By investing in routine sealcoating, property owners can significantly extend the lifespan of their parking lots and delay the need for more costly repairs.

When Is Resurfacing the Better Choice?

Resurfacing may be the better solution when your parking lot has progressed beyond basic maintenance needs.

Signs that resurfacing may be necessary include:

• Extensive cracking across large areas
• Surface raveling or crumbling
• Uneven pavement conditions
• Recurring repair issues

Addressing these problems early with resurfacing can restore the parking lot’s appearance and performance while preventing further deterioration.

Protect Your Parking Lot Investment

The choice between sealcoating and resurfacing depends largely on the current condition of your parking lot. Sealcoating is a preventive maintenance service designed to preserve healthy pavement, while resurfacing restores aging asphalt that has developed more significant wear. An experienced contractor can evaluate your lot and recommend the most cost-effective solution
