Powder Paint Spray Gun Instructions / Troubleshooting

 

Instructions for Use

Heat the part to be painted in a preheated oven at 350–400° F for approximately 5 minutes. A small propane torch or heat gun can also be used by holding the part with a needle nose pliers or by hanging on a fine wire and moving back and forth over the flame for a few seconds. Immediately after heating, hold or hang part sideways to allow spraying in a horizontal direction. Hold gun tip 4–6 inches from metal surface and spray in a sweeping motion.

The powder will adhere immediately and flow into a smooth finish. If metal has cooled to the point where the powder does not flow out completely, return piece to oven or wave the back side of piece over a torch flame until desired effect is achieved. More paint can be added as necessary. For maximum durability, cure painted part by hanging it in an oven for 15 minutes at 350° F.

Unused powder can be stored in covered jars. To change colors, simply blow out plastic tube and attach a new jar. Fill jars only half full for best results. To eliminate dust, work in front of an open cardboard box lying on one side with a vacuum hose inserted into a hole cut in the bottom side. The airflow created by the vacuum will keep powder in the box.

Troubleshooting

If you are having trouble with the flow of the paint try these things:

  • This is the most common problem...  the draw tube may be too long.  Trim the draw tube at a 45 degree angle to maximize the draw tube opening.  Also make sure the draw tube is trimmed back away from the the bottom of the jar.  Trim to about 1/4" from the bottom of the jar.  When you purchase extra draw tubes they are purposely longer than needed so you can trim them to the desired length.
  • Make sure the paint you are using stays loose in the jar.  Work with about 1/3 to 1/2 of the jar filled with paint to allow it to stay loose.  Cover the small air hole and shake it to keep it loose 
  • Make sure the sprayer tip is all the way tight
  • There is a thumb screw with attached to the draw tube, make sure that is all the way tight.
  • If the flow stops as you are spraying, try "pumping" it with the spray button.  If it stops completely, cover the tip with your finger and blow out the line.
  • If you are getting lots of overspray, turn down the air pressure.
