That widely accepted number originated from a study done in the mid-1800s ...Between 30 – 50% humidity. Seasonal changes and the climate where you live will play a role in your home’s humidity level, but the ideal atmosphere is below 50% humidity. As the moisture level in the air increases, you may begin to feel hot and sticky. An increase in moisture can also affect certain health conditions, like asthma, making it ...The optimal painting temperature would be 77ºF, but it is still acceptable to paint within a wide range of temperatures. Since temperature varies more widely outside, that is where most issues arise. We recommend planning your painting project for temperatures ranging from 35ºF to 100ºF and when humidity is as low as possible. If the air temperature reads 85˚F (29˚C), with 80 percent humidity, it will actually feel like 97˚F (36˚C). High environmental temperatures can be dangerous to your body.
