Paint needs several days to cure, and as the temperature dips, dew can form on surfaces and cause the water in the paint to evaporate too slowly. That affects how the paint holds up over time, including how well it resists cracking. Colder temperatures and moisture on the surface can also result in staining or mildew.
also, What happens if you paint below 50 degrees? Temperatures below 50 F (typically) can have a variety of negative effects on paint and paint application.
