6. Hair dryers and heat guns

2. Placing fans, osculating around the room we’ll also help dry out the air.

3.  Dehumidifiers are made to pull the moisture out of the air but they also expel heat out of the back as they’re working. So they may not be a great solution for summer unless you were thinking ahead and run the dehumidifier before you do your spray painting.

a heat gun is not recommended for certain surfaces like plastic and canvas because it will melt them very easily if you are not careful.
