Let us talk about sealcoating your asphalt driveway here in Billings. This is one of those things that homeowners often put off. They might also try to squeeze it in whenever they have a free weekend. Our Montana weather means that timing is important if you want that sealcoat to do its job as well as protect your investment.
When to Schedule Your Sealcoating in Billings
You cannot just sealcoat any time of year. The material needs specific conditions to cure properly. That means we are looking at a specific window for sealcoating in Billings. Generally, the best time for sealcoating in Billings is from late spring through early fall. You should think about May through September, and sometimes even into October if we get a nice, warm Indian Summer.
What we are looking for are consistent temperatures. This means daytime highs reliably above 50°F. Just as important, nighttime lows should not dip below 40-50°F for at least 24 hours after application. If it is too cold, the sealcoat will not bind right. It will also not cure properly. You will end up with a weaker, shorter-lived surface. That is just throwing money away. Our team has seen it happen when folks try to rush their sealcoating in April or push it too late into November.
For new asphalt, you actually want to wait about 6-12 months. This allows the asphalt to fully cure before that first sealcoat. After that, every 2-4 years is a good general estimate for sealcoating. This depends on traffic as well as sun exposure.
Weather Conditions That Make or Break the Job for Diamond Asphalt
Temperature is a big factor, as we just mentioned. It is not the only factor. Here is what else our team at Diamond Asphalt watches for:
- Rain: This is a definite no-go for sealcoating in Billings. You cannot apply sealcoat to a wet surface. It needs a good 24-48 hours of dry weather after application to cure. If rain hits it too soon, it will wash away or cure unevenly. Diamond Asphalt is always checking the radar when we are scheduling sealcoating jobs. Nobody wants to waste time as well as material.
- Humidity: High humidity can slow down the drying as well as the curing process significantly. Lower humidity allows for quicker drying because moisture evaporates faster. We aim for moderate humidity levels for the best sealcoating results.
- Sunlight: Direct sunlight helps speed up the drying process for sealcoating. Under bright, sunny conditions, sealcoating can dry in just a few hours. Cloudy conditions can extend drying times.
- Wind: A little breeze helps with drying. Strong winds can be a problem. They can cause the material to dry too quickly in spots, leading to cracking. Strong winds can also blow debris onto the fresh sealcoating. We have consistent winds here in Billings, especially out on the West End. Our team is always mindful of that for your sealcoating project.
Ideal conditions for sealcoating in Billings are usually between 50°F and 90°F. This is with low humidity as well as no rain in the forecast for at least 24 hours.
Protecting Your Sealcoating Investment Year-Round in Billings
Once your sealcoat is down and cured, you still have to take care of it. This helps you get the most out of your sealcoating investment. This is especially true with those crazy freeze-thaw cycles we get here in Yellowstone County.
- Give it Time to Cure: The sealcoat will feel dry to the touch in a few hours. It needs 24-48 hours before you can drive on it. Full curing can take up to 30 days. Driving on it too soon can leave tire marks. It can also scuff the surface as well as mess up the protection from your sealcoating.
- Keep it Clean: Regularly sweep off dirt, leaves, and debris. This is important before winter. Leaves and grime that sit on the surface can hold moisture. That is not good for any asphalt, especially when temperatures drop below freezing.
- Watch for Spills: Oil, gas, and other chemicals can break down your asphalt as well as your sealcoat. Clean up spills quickly.
- Winter Care: When the snow flies, be smart about snow removal. Do not use metal shovels or plows that can scrape the surface. Plastic shovels are your friend. Also, be mindful of de-icers. Some de-icers can be harsh on asphalt.
- Address Cracks Promptly: Sealcoating is great preventative maintenance. It will not fix big cracks. If you see new cracks forming, especially those wider than a quarter-inch, get them filled. Water seeping into cracks is the number one enemy of your asphalt. This leads to potholes as well as bigger problems down the road.
By understanding the best times and conditions for sealcoating, and by taking a few simple steps year-round, you will keep your Billings driveway looking good as well as lasting longer. It is all about working with our local climate, not against it. Diamond Asphalt is here to help with your sealcoating needs.
