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.

Choose a spray gun that comes with a trigger guard and safety shield.
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.
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.
Cover your nose and mouth with a painter's mask to avoid breathing in the fumes, and work in a well-ventilated area.
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.
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.
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.
