At this time of the year, our spray paint top tip is to make sure it’s warm enough to be spray painting. The optimum ambient temperature should be between 10 and 21 degrees. So if you intend doing some projects during the winter, always make sure the temperature is at least 10 degrees. Temperature also applies to the object you are spraying. If you intend spraying metal objects, make sure they are brought up to temperature, as the spray paint won’t stick to a cold object.
