How To Fix Clogged Spray Paint Cans

You’ve been there: in the middle of your project, the aerosol spray paint can won’t spray, it just quits; Here is how to quickly fix it…

Each aerosol spray can will have a rating on the back, usually near the bar code. Most spray paint cans are DOT 2Q which means they are rated to at least 270psi before it will burst, and is designed for operating pressure up to around 180psi @130F degrees. The vast majority of air compressors put out a max of 120psi — so you can’t get close to the safety rating. Most compressors also have a regulator to turn down the pressure — 50psi seems to be ample.
