Asphalt is a commonly used material for building roads, driveways, and parking lots globally. Although it is durable and able to withstand natural wear and tear caused by weather, traffic, and other external factors over time, it can still degrade.
Asphalt seal coating is a method commonly used to safeguard asphalt surfaces against deterioration. It involves applying a layer of liquid on the surface, which helps prevent moisture from penetrating and blocks harmful UV rays.
If you are considering applying a seal coat to your new asphalt surface but are unsure of when to do so, this article will provide you with a comprehensive guide on how long after new asphalt before sealing the surface.
What Is Asphalt Seal Coating?
Asphalt seal coating is a layer applied to asphalt surfaces that serves as protection against natural wear and tear. Its primary purpose is to seal any cracks or imperfections on the surface, preventing moisture from causing additional damage. Furthermore, it blocks harmful UV rays that can lead to surface fading and cracking over time.
Additionally, it improves the visual appeal of the asphalt surface, giving it a more vibrant and appealing look.
When Is The Best Time To Apply Asphalt Seal Coating?
For the most effective application of asphalt seal coating, it is best to wait for warm and dry weather. The recommended temperature range for seal coating is between 50°F and 85°F. Bad weather conditions, such as rain, heavy wind, or extreme cold, can interfere with the seal coat application process. If you apply seal coating in such weather conditions, the surface may crack, bubble, or peel.
Furthermore, after new asphalt surface has been laid, you should first wait for it to cure completely before applying seal coating to avoid negative side effects or damages to the asphalt surface.
How Long Should You Wait Before Applying Asphalt Seal Coating?
We suggest waiting until your recently-asphalted surface has completely cured and settled before adding a seal coat. The time it takes for the asphalt to cure will vary depending on different factors, such as the type of asphalt and the environment. Generally, it could take roughly 90 to 180 days for the asphalt to cure entirely before you can apply a new seal coat. Below are some of the factors to consider before applying asphalt seal coating:
- Temperature Conditions – The curing process of asphalt is greatly affected by temperature. Curing slows down in cold temperatures and can take longer to complete, while warm temperatures accelerate the process. To determine the optimal timing for sealing your asphalt surface, it is important to take into account the current weather conditions and the temperature in your surroundings.
- Traffic Conditions – If there is a lot of traffic on the new asphalt, it may not last as long as expected. To prevent this, it is suggested to wait for the surface to fully dry before allowing heavy traffic to drive on it. This means waiting at least 90 to 180 days before applying a new coat.
- Type of Asphalt – The time it takes for asphalt to cure depends on the type of asphalt used; warm mix asphalt (WMA) generally cures faster than hot mix asphalt (HMA).
- The Thickness of the Asphalt – The time it takes for asphalt to cure is influenced by the thickness of the layer; thicker layers require more time, while thinner layers take less time to cure.
How To Ensure The Asphalt Is Ready For Seal Coating?
Testing the asphalt surface before applying a seal coat is essential to ensure proper adherence to the base and to detect any issues such as oiliness or aging. Follow these steps to make sure that your newly asphalted surface is ready for seal coating:
- Check for Oily Spots or Gasoline Residue – Make sure to clean and completely dry any oily spots, gas or oil leaks, or other contaminants from the new asphalt surface before applying the seal coat. Failure to do so could result in poor adhesion and create problems.
- Check for Cracks and Potholes on the Surface – Applying a seal coat on a cracked or potholed surface may fill these weak spots with the seal coating material, leaving a rough and unappealing surface. It is essential to fix all the cracks and potholes before applying a new seal coat.
- Let the Asphalt Surface Fully Cure – As mentioned before, it is recommended that you wait for a period of 90 to 180 days or until the asphalt has completely cured before applying a fresh sealcoat.
- Consult A Professional Contractor – If you are not sure about the condition of your asphalt surface, it is best to consult a professional contractor like American Asphalt Sealing INC in Post Falls for advice. They can check the asphalt and advise you accordingly on when to apply seal coating.
Conclusion
Overall, applying asphalt seal coating is an effective way to maintain the quality and longevity of your pavement. However, it is crucial to wait until the asphalt surface has completely cured before applying the seal coat, in order to prevent any adverse effects or damage.
And in order to prepare your asphalt for seal coating, it is important to thoroughly inspect the surface. Look for any signs of oil stains, cracks, or potholes. If you’re unsure about the state of your asphalt, it is recommended to seek the advice of a professional contractor. By following these tips, you can ensure that your asphalt is properly prepared for seal coating.
