Why Do Asphalt Seal Coats Peel-Off?

When you have an asphalt driveway or parking lot, it is essential to keep it in good condition. This means regularly sealing it with a coat of asphalt sealant. Asphalt seal coats are supposed to protect your asphalt driveway or parking lot from weathering and wear and tear. However, sometimes this sealant can start to peel off!

PowerSurge Plus LLC discusses why the seal coat peels off and how to avoid it in this blog post!

The Substrate Isn’t Properly Prepared.

The first reason is that the substrate isn’t adequately prepared before the sealant is applied. If the surface isn’t clean and debris-free, the sealant won’t stick properly and will eventually peel off.

The Sealant Wasn’t Applied In A Uniform Layer.

If the sealant is not applied evenly, some areas will be thicker than others and eventually peel off.

Not Allowed To Cure Properly

Another reason why the seal coat peels off is when it isn’t allowed to cure correctly before being exposed to traffic or extreme weather conditions.

Unprofessional Contractor

If your contractor is not professional and doesn’t apply the sealant correctly, it won’t stick properly and will eventually peel off.

Old Or Expired Sealant

If the sealant is old or has expired, it won’t work as well and will be more likely to peel off.

Excess Moisture

Excess moisture in the air when the seal coat is applied causes it to swell and peel off.

Wrong type Or Inferior Quality

Using a seal coat that’s not meant for asphalt will swell up and peel off. Also, if the asphalt isn’t good quality, it will start to wear out faster, and the seal coat will eventually peel off.

Temperature

If the temperature is too high or too low when the seal coat is applied, it will cause it to swell and peel off.

Traffic

The more traffic a road gets, the more wear and tear it experiences. It can cause the seal coat to start to peel off.

How to Apply Asphalt Seal-Coat Properly?

1. First, you need to make sure the surface is clean and free of debris before applying the seal coat. It will help ensure that the seal coat adheres properly.
2. Apply the seal coat evenly, making sure to cover all areas. If you miss any spots, the seal coat may not adhere properly and could lead to cracks or other problems down the road.
3. Please wait for it to dry completely before driving or parking on it.

As you can see, there are many reasons why asphalt seal coats may peel off. If you’re having this problem with your road or driveway, it’s essential to identify the source of the issue so that it can be fixed. Contact a paving contractor to help you get your road or driveway looking and functioning at its best.
