Painting Tips Â» Hot Weather Painting. Satisfactory painting in hot weather and high humidity can sometimes be difficult. Certain steps can be taken to minimize the effect of these conditions. Temperatures exceeding 90Â°F will often cause paint to dry too fast. Dry-rolling will be accentuated with these higher temperatures.
As a general rule, the air temperature for good painting conditions ranges from 55 degrees to 85 degrees. Unfortunately, when applying paint or stain it is the surface temperature, not the air temperature that is important. Air temperature and surface temperature can be miles apart.If a wood deck or wall is in direct sunlight it may well be 30 to 50 degrees hotter than the air temperature.One sunny day in May the air temperature on our test deck was 55 degrees, but the surface temperature of the wood was over 95 degrees. In other words, it was already too hot to stain successfully.pply stain only at the proper temperature. For most stains, 70 degrees Fahrenheit is the optimum, with the safety range from 50 to 90 degrees Fahrenheit. Stains do vary, so check the label first.
