It is not recommended to seal the layer of your driveway during the winter season, as the colder temperatures can have a negative impact on the performance of the sealant. According to Denny, asphalt should be sealed every three years for optimal results. The best time to do this is during the summer or early fall, as asphalt is more flexible and easier to handle in warmer temperatures. Generally, you can expect to seal a driveway every three years. Some homeowners choose to seal their asphalt entrances annually, but they don't do the same with concrete.
Sealing concrete every year can cause more fine cracks, so if you have a concrete driveway, it's best to re-seal it every five years. If you're a homeowner with an asphalt pavement driveway, you may not be aware that you need a sealed liner or think that fall is too late to do so. However, if you have a commercial car park and need it to be operational quickly, we recommend sealing it in June, July or August so that the sealant can heal and dry faster.
