Is there a optimal temperature painting outside exteriors?
Many paint manufactures tell homeowners to apply paint that is solvent based when the surface temperature is above 45 degrees and latex type paint when the surface temperature is at least 50 degrees. Lower temperatures can cause paint that is solvent based to thicken quicker, which can cause paint brushes to become very thick and the paint is applied heavier and dries slower. What this means is that the paint can run, wrinkle, and sag on surfaces that are vertical. It also is the case when it is colder outside that there is a reduced rate of coverage for every gallon of paint that you use. When the temperature is lower than 50 degrees latex paint dries slower, especially when there is high humidity in the air. This can cause the paint to coalesce and may lead to the paint forming a poor film. It can also cause the paint to not cover as well.
