Generally speaking, the best time to paint a house exterior will depend on your area’s weather and overall climate.
For example, it’s ideal to paint in the late spring or early fall in milder and hotter climates to avoid the chance of extreme heat. When the paint is exposed to high temperatures, it will cause the water in the paint to evaporate at a much quicker rate. This results in faster drying times and inconsistent film formation. This can lead to the paint appearing patchy in areas where it has dried too quickly. High temperatures can also reduce the durability and adhesion of the paint film. In colder places, it’s better to paint in the summertime to avoid temperatures below 50 degrees Fahrenheit, as the paint will not cure properly.
