Winter’s harsh weather can damage your asphalt, so it's essential to seal it before the cold sets in. Sealing asphalt during fall is the best way to protect your driveway from snow, ice, and freezing temperatures. With the right preparation and attention to weather conditions, you can ensure a durable, long-lasting seal. Here’s how to seal your asphalt before winter and keep your driveway in top shape.
1. Monitor the Weather Forecast
The ideal conditions for applying asphalt sealant are when both the pavement and the air temperature are at least 50°F and rising. Applying sealant in temperatures below this can lead to issues like tracking, uneven application, and compromised durability. Be sure to check the weather forecast before starting your project. If rain, snow, or thick fog is predicted, it’s best to delay the application to avoid poor results and wasted material.
2. Modify the Sealant Mixture for Faster Drying
To help speed up the curing process, consider using a modified sealant mixture. Specialty additives can help the sealant dry faster by evaporating moisture more quickly. If you're using a standard mix, try reducing the amount of water by about five percent to encourage faster drying. This step is especially important when temperatures are lower. If temperatures drop below 50°F, your sealant may freeze before it has a chance to properly cure, leading to cracking and peeling.
3. Keep the Surface Clean from Debris
When sealing asphalt, be mindful of falling debris, especially in the autumn. Leaves, pinecones, and other small items can cause indentations or become embedded in the fresh sealant. Regularly remove debris from your driveway while the sealant is drying to avoid these issues. Be careful not to step on the curing surface. Use a broom or similar tool with a long handle to gently move any debris without disturbing the sealant.
4. Allow Sufficient Drying Time
Once you’ve applied the sealant, be patient. The cooler the temperature, the longer the curing process will take. Typically, you should allow two full days for the sealant to fully cure. If you’re applying multiple coats, give your driveway more time to dry in between applications. Allow four to six hours between coats for the best results. It’s better to start your sealcoating job in the morning, allowing the sun to assist with drying, but make sure the fog and early-morning chill have lifted before applying the sealant.
5. Plan for Early Afternoon Completion
If you finish your sealcoating job by early afternoon, your driveway will have a few extra hours of sunlight to help with the drying process. Keep this in mind as you schedule your project to ensure the sealant has ample time to cure before nightfall.
