Sunlight exposure is extremely important, especially if you absolutely have to apply the crack sealing in cooler temperatures. The best time to sealcoat is as early in the morning as possible on bight sunny day, even though they are usually few and far between in the winter.
The earlier the crack sealing is set in the daytime, the more time it has to dry and the rays of the sun will facilitate the drying process tremendously. At night, the air is always cooler and this will not only slow down the drying and curing process of the sealcoat. The moral of the story is that you should be cautious about asphalt crack sealing in the winter and only do it when it is absolutely necessary.
