Painting your home’s exterior is one of the best projects you can tackle. Applying a new coat of paint creates an interesting and dramatic change to your home’s overall appearance. However, since it’s wintertime, you might be wondering—“how cold is too cold for exterior painting?”
Hynes Roofing & Siding, your local roofing contractor, also offers exterior and interior painting services. Today, we shed light on the ideal outdoor conditions that will help make your home exterior paint job a success.
Weather and Exterior Painting
Before you decide to take on an exterior painting project, you must first consider the current weather in your area. Paint needs several days to cure, and the outdoor temperatures can influence how well the coat dries and adheres to the surface of your exterior siding or window frame.
A decrease in temperature can cause dew to form on the painted surface, which then causes the water to evaporate too slowly. If you do the project on a warm day, the paint won’t form a good film if temperatures drop too low come nighttime. The coat of paint may not hold up and can result in cracking, peeling and staining.
The Best Temperatures for Exterior Painting
The minimum and maximum temperatures recommended for exterior painting depend on the type of paint being used. Generally, oil-based paint can be applied when the temperature is between 40 to 90 degrees Fahrenheit. For latex paint, it must be between 50 to 85 degrees Fahrenheit. Also, take note of the relative humidity—the best drying will occur if it is between 40% to 70%.
If you are thinking of doing the project around this time, it might be better to wait until the spring. This is especially true if the temperature over the next few days will be hovering within the below-40-degree mark and that not much sun is expected.
