Trying to find the perfect day for your paint project? The Paint Department staff at PaulB Hardware offers the following tips regarding the impact of weather on painting projects:
If you’ll be painting an exterior, it’s best to choose a day that isn’t too hot. Exterior paint in direct sunlight may dry too quickly and might not adhere properly. It can also be rather unhandy as the paint may skim over in the tray, and begin to dry on your brush and/or roller.
For interior painting, heat levels should be above 50 degrees F. A cooler room will result in a longer dry time.
Humidity level is not a big deal, although a high humidity level may slow down the drying process of the paint. Painting is not recommended if there is a possibility of condensation forming on the surface.
A rainy day would be fine for painting, as long as good ventilation is possible and the surface you are painting won’t get damp or wet. If you are painting on a day that is humid, having a fan or a breeze blowing through the room would be a good idea, to help speed up drying time.
The most important factor is that the surface you are coating is dry and clean.
