Painting in the summer can be a challenge. Indoors or out. Often on commercial projects there is no air conditioning or air movement so it can get pretty uncomfortable. When you are painting, especially spraying, you are adding even more humidity into that environment. It’s not uncommon to see the windows dripping with humidity when spraying inside.
Painting outside has it’s own challenges. Direct sunlight being one of them. When painting outside you never want to paint anything subjected to direct sunlight. We always paint on the opposite side of a house to the sun. Working in direct sunlight will potentially dry the paint too fast and you don’t need the sun beating down on you either.
Most people know the basics. Stay well hydrated. Gatorade along with water is a good idea. Bandanas soaked in cool water before wearing them is a big help. Stay out of the sun when possible. Sun block is of no help either you will be sweating it off quickly. Start work earlier in the day and break off when it’s the hottest outside like two or three.
Take breaks more often. Eat smaller meals or snacks while working or taking lunch. If you feel dizzy, overly tired, etc. Call it quits for the day. There is always tomorrow to pick up where you left off. OSHA has some good tips for working in the heat.
