Most people understand that painting outside in winter isn't the best idea. When it gets colder, it's best to postpone any outdoor painting project until the warmer months arrive. On the other hand, you may wonder if painting outdoors during the hottest months of July and August could be detrimental to drying the paint. The truth is that the best time to undertake a painting project is when the temperature is moderate and with very little wind.
We have found that the ideal temperature is between 60 and 85 degrees Fahrenheit. A little wind may not seem like a big deal, but it can cause paint to dry too quickly. Second, high humidity levels mixed with direct sunlight can heat the surface temperature of the coating and cause bubbles in the paint. When painting a house, most professionals begin the process by following the sun's shade around the house.
When it comes to exterior painting projects, it's important to know the best temperature for outdoor painting. In fact, the temperature ranges recommended by paint manufacturers per product are usually listed on the sides of the can. First of all, you should consider the weather conditions before starting any exterior painting project. Obviously, early summer and autumn tend to have the most ideal weather conditions and temperatures for exterior painting.
With a surface that's too hot, paint never has a chance to adhere and may leave you with a cracked, peeling, or blistered exterior (below). However, keep in mind that for the paint to dry and cure properly, the air and surface temperature must not drop below 35° for 36 hours after application. Before choosing your favorite paint color, you'll want to know what type of paint to look for. For example, the exterior paint temperature should be between 50 and 70 degrees Fahrenheit when using latex paint.
But these high temperatures raise a fairly common question: How much heat is too hot to paint the outside of your house? Often, paint manufacturers suggest a low-temperature paint additive to normalize the product.
