While you can spray paint indoors in a well-ventilated area for a more controlled environment, we recommend tackling all your spray painting projects in an outside space foroptimal safety*. Spray painting outdoors means there are several additional considerations to keep in mind prior to diving into your next DIY endeavor. You can’t control the weather, but it is a key factor in determining the best time and place to spray paint.
Best conditions for spray painting
Ideally, dry conditions with minimal wind, low humidity and some cloud cover work best for spray painting**.
Humidity: Because high humidity slows spray paint dry time, we recommend spraying when humidity is below 60%. Additionally, high humidity can lead to condensation on surfaces, resulting in lifting or peeling after coating rather than a smooth, long-lasting finish.
Temperature: It’s best to spray paint in temperatures between 55° and 75°F but be sure to check your can label as some spray paints require varying ranges. When applied in temperatures above or below this range, spray paint can set too quickly, resulting in air bubbles. For the same reason, avoid painting in direct sunlight and keep in mind that the time it takes spray paint to cure and dry tends to be longer in cooler conditions.
Wind :Avoid spray painting on windy days. Windy weather makes it difficult to control the direction of your spray and interferes with paint coverage. This results in more work—and cleanup—once your project is finished. If you are painting on a breezy day, be sure to set your workspace up with the wind at your back—blowing away from both you and your project.
