Sealcoated driveway

When is Sealcoating Season?

In general, most contractors operate between April 15th and November 1st, since that’s when the weather is most likely to be warm enough and the humidity is lower. However, even within this time frame, it’s important to consider the unpredictable weather in October and November. Just because there’s no snow on the ground doesn’t mean it’s warm enough to sealcoat.

Risks of Sealcoating When it’s Too Cold

What happens if you decide to sealcoat your driveway when it’s too cold? If the sealcoating solution is water-based, the cold temperatures might cause curing issues. The sealcoating won’t set properly and the sealcoating finish will look uneven and wear off faster. This can be especially challenging if it’s a high-traffic commercial parking lot.

The Best Temperature Range

Ideally, the temperature should be between 55 degrees and 90 degrees Fahrenheit, with the weather getting warmer during the course of the day. It generally takes 24 hours for the sealcoating to dry and cure, so check the weather to make sure it won’t get too cold at night, as that will undo all your hard work.

Effects of Rain and Snow on Sealcoating

Just as cold weather affects sealcoating, so do rain and snow, not just due to temperature but to moisture. If water gets into the fresh sealcoating, it could cause peeling and separation. In order for sealcoating to cure, it needs a proper amount of dry heat and at least two hours of consistent sunlight.

Protecting Your Driveway in Winter Climates

Even when it’s too cold to sealcoat, there are still other ways to protect your driveway in winter climates. You can caulk over any cracks in the asphalt and seal them to keep them from getting bigger. To make your driveway safer to walk and drive on, put cat litter, sand, or salt on it if there’s ice or snow.
