How To Prime A Paint Sprayer? [Step-By-Step Guide]

Step 1: Take The Pressure Off

When it comes to priming a paint sprayer, your first step is to release the pressure. Throughout the procedure of the priming sprayer, wear protective glasses, a respirator, and gloves. We have given some suggestions on how you can release the pressure:

  • Be sure to engage the trigger lock
  • Put the switch of the device in the off position.
  • Adjust pressure to the lowest setting
  • Invert the tip to remove the trigger lock
  • Grasp the metal parts on the sprayer, and place it firmly on the ground. In that case, trigger the sprayer to release the pressure.
  • Engage sprayer trigger lock
  • Move the valves that are present in the device to the dominant position.

Step 2: Prime The Pump

Now, it’s time to prime your pump. Follow the steps given below to complete the process of priming the pump:

  • Utilize a trigger lock
  • Remove the gun’s guard and tip.
  • Put the drain tube and intake pipe into separate buckets of priming paint.
  • Place the “primary” or “drain” position of the prime valve.
  • Verify that the pressure control is set to the lowest level
  • Activate the machine’s “ON” switch.
  • Until the motor starts, apply more pressure. Allow the paint to flow easily through the machine to the trash container’s exit. 
  • The sprayer should be turned off.

Step 3: Prime The Hose And Gun

Once the priming of the pump is done, proceed to prime the hose and gun. The tips below will help you complete the process of priming the hose and gun: 

  • Place the gun firmly on the trash can, release the trigger lock, and keep holding
  • Set the “Spray” position on the primary valve
  • Run the appliance continuously until the paint starts to come out of the outlet. Release the trigger after putting the device in “OFF” mode
  • Pull the trigger while bringing the gun up near the paint bucket. Turn the switch there to “ON” and let the paint sprayer run for around 15 to 20 seconds.
  • Then, let off the trigger and let the pump develop pressure.
  • Lock the gun trigger
  • The tip should then be tightened and screwed back on.

Step 4: Test The Spray 

Once the process of priming the paint sprayer is complete, test the spraying of paint. The test will ensure how effectively the material comes out of the sprayer tip. You can use cardboard for a spray test. It will be easy to test your sprayer on cardboard and test the spray pattern. Follow our instructions on how to test the spray: 

  • Place the pressure control knob in the center
  • Maintain an 11/12 inch space between the sprayer’s tip and the surface when holding it. The trigger lock should then be taken out and sprayed over the cardboard.
  • Your test pattern’s edges should be rounded and easy to merge. When spraying paint, gradually raise the pressure if you notice any heavy edges, and keep going until you get the perfect edges you like.

3 Safety Tips You Can Follow When Priming Your Paint Sprayer

  • While spraying, keep your distance from the sprayer. If you stand too close to the paint sprayer, the extreme pressure it produces can easily penetrate your skin, which is very harmful. Therefore, you cannot ignore this risk. When spraying an object to test the sprayer, keep the nozzle away from you and the people around you
  • Use a full-face respirator throughout the procedure, and make sure there is enough airflow in the space. It would be ideal if you arranged the work of priming in an open area to prevent the impact of harmful paint fumes.
  • Some primers for paint are pretty explosive. That’s why to keep electrical devices, gas, stoves, and other surrounding heat sources off to avoid any potential untoward incident.


With the proper setup, you can consistently apply a clean coat and keep your paint sprayer operating correctly for a more extended period of time. Using a sprayer, priming procedures can vary. Actually, it depends on the kind of model you use. The majority of paint sprayers are made with a secondary priming hose in addition to the central painting hose.

An easy-prime button is used by sprayers that have a priming hose. Thanks to your regular priming methods, your pump will always feel brand new and prepared for the next project. Always put on your safety equipment before priming.
