DON’T PANIC! You might have pulled the trigger back too hard. If the trigger is pulled back too hard, it can “stick”. Simply put your index finger behind the blue trigger and push it forward. A “pop” or “click” should happen. If you push on the trigger a few times, it should start spraying again.
If you don’t leave your can with the trigger in the correct “off position”, the gas will seep out, rendering the can unusable. When done using the can, make sure the trigger is fully pushed forward and in the off position. Even pulling lightly on the nozzle will allow the gas to seep out.
Paint may build up in the nozzle after it is used. If this happens, pick off any excess dried paint from the nozzle opening, then flip the can upside down and spray to clear the passage. The force of the spray should clear the way. We also suggest storing your used paints upside-down in water if you will not be using them right away (with trigger in off position).
