Step 1: Release the pressure of the air in the sprayer

Reduce the pressure present in the paint sprayer to make cleaning the sprayer easier. Turn on the trigger guard to prevent spray paint from going your way. Turn off the paint gun then lower the pressure as low as possible.

Remove the trigger and spray any remaining paint in the sprayer into the waste bin to release any built-up pressure. This makes it safer for you to clean the spray gun.

Then you re-screw the trigger and valve, depending on the paint gun you use to adjust it correctly.

Step 2: Rinse off the remaining paint in the paint sprayer

Drain all paint present in the paint gun system. Both the tips and the paint gun guards should also be removed. Place the end of your exhaust in the empty bucket and start flushing. If you regret the remaining paint you can discharge them into a clean bin for further use.

  • Soaking the tail of the gun will damage the inner seal, leading to a situation where the trigger has not been pulled but the gas at the cap has leaked out.
  • Do not clean by removing the nozzle of the spray gun (limited removal, the needle is still removable).
  • When the nozzle is not installed tightly, the spray will spray out unstable, jerky. Compressed air flows back into the paint cup.
  • If you use paint thinner to clean the sprayer, always be sure to wear appropriate PPE, at least gloves, goggles, and a respirator. This last one is important as they will give off fumes that can be absorbed and ingested through absorption and respiration. This type of product needs to be stored carefully, preferably in open spaces.
