Common Questions About Asphalt Sealcoating Answered


Asphalt pavement can be a long-lasting and economical option for driveway or parking lot surfaces. However, proper maintenance is essential to ensure longevity and a professional-looking finish. One of the best ways to protect your pavement investment is through asphalt sealcoating. It’s a process that involves applying a protective layer over the surface to seal the small cracks and prevent further damage and wear. If you’re considering sealcoating for your property, you may have some questions and doubts. In this blog post, we’ve answered some of the most common questions about asphalt sealcoating.


1. What is Asphalt Sealcoating?

Asphalt sealcoating is the process of applying a liquid coating, made from a blend of asphalt emulsion, water, and other additives, over the existing asphalt surface. The mixture is spread evenly with a squeegee or spray equipment, filling in the small cracks, pores, and rough spots on the surface. The sealcoat dries and cures to form a thick, protective layer that shields the underlying asphalt from UV rays, moisture, and traffic damage.

2. Why Should I Sealcoat My Asphalt Pavement?

There are several reasons why protecting your asphalt pavement with sealcoating is a wise decision. First, it enhances the curb appeal and overall aesthetics of your property by giving the pavement a fresh, uniform, and jet-black appearance. Second, it prevents oxidation and slows down the aging process of the asphalt, extending the lifespan of the pavement by up to 30%. Third, it shields the surface from water penetration, ice formation, and chemical spills that can cause cracks, potholes, and other damage. Fourth, it minimizes the need for repair or replacement, reducing the long-term cost of pavement maintenance.

3. When is the Best Time to Sealcoat My Asphalt?

The best time to sealcoat your asphalt pavement depends on several factors, such as the weather, the traffic volume, and the condition of the pavement. In general, the ideal time for sealcoating is during the summer or early fall when the temperature is warm and dry. The warmer the temperature, the quicker the sealcoat will cure. However, if you live in an area with high traffic or heavy usage, you may want to schedule the sealcoating during the off-season or when the traffic volume is low. Finally, if your pavement shows signs of severe damage, such as deep cracks or potholes, you may need to repair those first before applying the sealcoat.

4. How Much Does Asphalt Sealcoating Cost?

The cost of asphalt sealcoating varies depending on several factors, such as the size of the pavement, the condition of the surface, and the local labor and material costs. Generally, the cost ranges from $0.15 to $0.25 per square foot. The larger the pavement, the lower the cost per square foot. However, the cost per square foot may increase if the pavement requires preparation work, such as crack filling or cleaning. The best way to get an accurate estimate of the cost is to contact a professional asphalt paving contractor, who will assess your pavement and provide you with a free quote.

5. How Long Does Asphalt Sealcoating Last?

The lifespan of asphalt sealcoating depends on several factors, such as the quality of the sealcoat material, the exposure to weather elements, and the traffic volume and type. In general, a well-applied and maintained sealcoat can last for up to 3-5 years. However, it’s essential to monitor the pavement regularly and perform touch-up sealcoating when needed, especially in high traffic or heavy usage areas. Proper maintenance, such as sweeping, cleaning, and crack sealing, can also extend the lifespan of the sealcoat.



Asphalt sealcoating can provide numerous benefits to your pavement, including protection, durability, and aesthetics.
