What’s the Right Outdoor Temperature Range for Exterior Painting?

Painting the exterior of a house isn’t an easy job. It’s far more complicated, far more difficult, and far more dangerous than painting the walls of a room. And there’s one additional factor that you don’t have to consider when doing interior painting – the weather. Of course, you likely know that you don’t want to paint your house when it’s raining, but did you know that the outside temperature can also impact the quality of your paint job? Keep reading to learn more.

How Cold Is Too Cold?

Cold weather tends to be more detrimental to painting than hot weather. You want it to be at least 50 degrees Fahrenheit during the day to paint. But, more importantly, you don’t want the temperatures to drop below freezing (32 degrees Fahrenheit) at night for several days after applying the paint. So, be sure to pay close attention to the lows listed in the weather report before you start painting or you schedule your painting contractor in Mesa.

Why does this matter? The paint on your house takes several days to cure. When the temperature drops, dew can form on your home, causing the water in the paint to evaporate too slowly and not allowing it to cure properly. Additionally, below-freezing temperatures will impact how well your paint holds up over time; if you paint when the lows are too cold, your paint job won’t resist cracking as well as it should and may be prone to staining or mildew.

How Hot Is Too Hot?

While high temperatures aren’t as much of a concern for exterior painting as low temperatures are, you should still consider the outdoor temperature when painting during the summer. While there’s no hard rule about how hot is too hot to paint, if temperatures are above 90 degrees Fahrenheit, you’ll want to pay attention to how hot the outdoor surfaces are that you want to paint.

If you place your hand on the wall of your home, the window shutter, or any other outdoor surface you want to paint and you can’t keep your palm on the surface for more than a few seconds, then it’s too hot. You’ll want to wait for cooler temperatures—and cooler surfaces—before you start painting or bring in your painting contractor.

Pay Attention to the Paint

While the temperatures mentioned above are an excellent guideline to follow, different paints have different ideal temperature ranges. Check your paint can’s label to see what temperature range the manufacturer recommends for that type of paint. If you’re working with a painting contractor (and you really should be for any exterior painting job), don’t be afraid to ask what kind of paint they’re using so that you can verify it’s appropriate for current outdoor temperatures.
