Sealcoating: Frequently Asked Questions

Regardless of whether you have an asphalt residential driveway or a business parking lot, it is important that the asphalt is maintained to ensure it remains functional and visually appealing. Sealcoating is one thing you can do to help prevent several defects from forming that can reduce the appearance of asphalt and potentially result in liability issues. Keep reading to learn more about the way that sealcoating works and why it is so important.

Why Does Asphalt Deteriorate?

Moisture is one of the main reasons that asphalt breaks down. As soon as cracks occur in the surface of the asphalt, moisture is able to seep directly into the ground and cause a variety of issues like depressions, rippling, and potholes. Once a sealcoating is applied, the asphalt's surface is protected from the intrusion of water and defects that may be caused by gas and oil spills.

How Can Asphalt Be Prepared for Sealcoating?

To ensure that the sealcoating contractors have adequate access, you should make sure that all machinery and vehicles are cleared off of the asphalt surface. In addition, before the sealcoating product can be applied to the asphalt, the surface will need to be thoroughly cleaned. This cleaning generally consists of power washing the asphalt so that all built-up dirt and grime can be removed.

How Long Until the Asphalt Can Be Driven On?

Although the exact timeframe will depend on the temperature and humidity levels, the general rule of thumb is for you to wait roughly 48 to 72 hours before a vehicle is driven on the asphalt once it has undergone the sealcoating process. However, it may be possible to walk on the asphalt after a minimum of 24 hours. Speak to the sealcoating contractor for timeframes based on your climate.

How Often Should Sealcoating Be Performed?

Ultimately, an asphalt surface should be sealed every one to three years for optimal results. In addition, it is best for the sealcoating product to be applied in temperatures of 50 degrees or higher and on a dry day so that it is able to properly adhere to the asphalt surface.

If your asphalt driveway or parking lot is starting to wear down and look dull from its initial installation, or if it has been a couple of years since your last sealcoating application, get in touch with an asphalt paving service in your area to discuss the sealcoating process and get an estimate for your property.
