How to paint with a spray gun
(A. Johnson)

It takes a long time to paint a room using a paint brush. If you use a paint roller, the chore goes much faster. But if you really want to speed up the process, use a spray gun. Some spray gun styles have a tube that is inserted into a can of paint and the paint is pulled up the tube and through the paint gun nozzle onto the surface. Other spray guns have a hopper which is filled from the can.

  1. 1

    Choose a spray gun that comes with a trigger guard and safety shield.

  2. 2

    Flush the unit prior to adding paint, following the manufacturer's instructions. One way to do this is to run water through the unit instead of paint.

  3. 3

    Cover the surrounding area with dust sheets and use masking tape when necessary. A spray gun will generate a mist of paint that can settle on areas where you don't want paint. Be sure to cover those areas to prevent unwanted paint speckles.

  4. 4

    Cover your nose and mouth with a painter's mask to avoid breathing in the fumes, and work in a well-ventilated area.

  5. 5

    Add paint to the hopper or insert the tube into a can of paint after it has been sufficiently stirred and blended. If your unit has a hopper, filter the paint through nylon when adding it to the hopper. Plug the unit into an electrical socket and turn on the machine.

  6. 6

    Starting at the top of the wall, and using even horizontal strokes, spray one patch at a time--about 3 or 4 feet square. Keep the gun nozzle about a foot from the surface. Release the trigger of the gun before moving downward to the next patch. Each patch should overlap slightly.

  7. 7

    Turn off the unit and disconnect it from the electrical socket before cleaning the machine. It will need to be cleaned immediately after using, following the manufacturer's instructions.
