When it comes to painting the exterior of a business, keeping an eye on the weather is critical. For the paint to dry as fast as possible, contractors will avoid working when the temperature is below 60 degrees Fahrenheit or if it is above 90 degrees. The latter is a bigger issue for contractors in Arizona.

Contractors will avoid painting in direct sunlight whenever possible, which means they may look to work early in the day or later in the evening when the sun is no longer beating down on the painted surface. It is also important to avoid painting when it is wet or windy outside. Obviously, rain will dilute the paint before it gets the chance to dry, while wind will blow dirt on the paint or may cause it to dry too quickly.
