What Factors Cause A Seal Coat To Fail Before It’s Time?

Key takeaways:

  • Seal coating can fail due to several factors, including improper application, incorrect material selection, and exposure to harsh weather conditions.
  • These failures can seriously damage your driveway or parking lot, including cracking, potholes, and fading.

Wanting to care for your driveway or parking lot can be a daunting task, especially when it comes to seal coating. Seal coat application is an essential step in protecting your asphalt from damage. Still, it can sometimes fail before its time due to certain factors.

At Action Construction Asphalt & Concrete, we understand everything about seal coating. Our team will tell you about the top seal coat damage and how you can apply it more precisely.

1. Improper Application

One of the most common reasons a seal coat fails prematurely is improper application. If the seal coat is not applied evenly or if it is applied too thickly, it will not adhere properly to the surface and will eventually peel off. Resultantly, your surface will only enjoy the protection it needs for a short time. To avoid this, please ensure that the seal coat application is made evenly and at the right thickness.

2. Poor Surface Preparation

When your seal coating contractor fails to follow proper surface preparation procedures before sealing your asphalt, it can lead to close coat failure. For the seal coat to properly adhere and lock in moisture, you must clean your surface before seal coat application. This includes removing grease, oil, and loose or crumbling pavement. If any of these contaminants are left on the surface, they can cause the seal coat to fail prematurely.

3. Incorrect Mixing Ratio

The adequate ratio of seal coat mixing with adhering is critical. If your seal coating contractor fails to get this ratio right, the sealer will not adhere properly and will not last as long as it should. This can cause your seal coat to fail much sooner than expected, resulting in costly repairs and a frustrating experience for you as the property owner.

4. Use of Inferior Materials

For your seal coat to be durable and long-lasting, it must be made with high-quality materials. Choosing a low-quality seal coating product, or relying on an inexperienced or unskilled contractor to apply it, can result in a seal coat that fails prematurely and causes extensive damage to your property. You’ll be looking forward to a costly and time-consuming repair job, so choosing your materials and contractor is essential.

5. Exposure to Extreme Weather Conditions

If you live in an area with harsh sunlight, high temperatures, or in-climate weather, your seal coat won’t last as long. Over time, it will begin to peel off. There may also be issues with the concrete underneath, as exposure to harsh weather can cause it to deteriorate and weaken. You can only damage such seal coat damage with a costly and time-consuming pavement replacement.

6. Poor Storage Conditions

If the seal coat is stored improperly, it can damage or compromise. For example, suppose the seal coat is left outside in direct sunlight for extended periods. In that case, it can become brittle and lose effectiveness. Likewise, if you don’t store your seal coat in a cool, dry place out of the sun, it may become damaged or spoil. When choosing a seal coat, consider the storage conditions and ask about proper handling from your seal coating contractor.

7. Use of Contaminated Materials

If a seal coat is applied over contaminated materials, it may be more prone to damage and early failure. For example, if you don’t remove any oil stains from your driveway before applying the seal coat, it may become discolored or brittle over time. To avoid this issue, thoroughly clean and prepare your driveway before applying the seal coat.


8. Incorrect Application

Another common cause of seal coat failure is incorrect seal coat application. What does it mean? This can include not allowing enough time for the seal coat to dry before driving on it or using a seal coat that is too thin. Work with a reputable seal coating contractor. They will apply the seal coat correctly to ensure optimal performance.

Best Practices for Seal Coat Application

Apply only to dry surface 

To protect your pavement from seal coat damage and ensure the longevity of your seal coat, it is essential to take certain precautions when applying a seal coat. First and foremost, use the seal coat only on a parched surface. This means waiting until any rain or snow has passed and for the pavement to be fully thawed and dry before applying.

Select a high-quality seal coat formula

Failing to choose the correct seal coat formula can also lead to premature seal coat failure. When selecting a seal coat, opting for a quality product formulated to withstand the elements and stand up to wear and tear is essential.

Keep the surface free of debris or dirt.

As we also discussed before, it is vital to maintain a clean surface before applying a seal coat. This means removing any leaves, sticks, or other debris from the pavement before seal coat application. Always thoroughly sweep or pressure wash the area to ensure a clean seal coat application.

Dry for 24 hours before traffic is allowed on the surface

You need to let your seal coat dry properly to maintain its durability. To ensure that it is completely dry before allowing traffic on the surface, you should wait at least 24 hours after the seal coat application.

Reapply every 2-3 years to ensure optimal performance of your seal coat.

Of course, your seal coat application is only as good as the quality of your seal coating contractor. Remember the reapplication maintenance, as seal coats typically last for 2-3 years before needing to be reapplied. By maintaining a regular seal coat schedule and working with a reputable seal coating contractor, you can enjoy the many benefits of a properly sealed surface for years to come.
