If you have large areas to cover, a spray paint machine can make painting easier and faster.It can present a number of problems, including the possibility that you may get paint on items you didn't intend to paint.Proper preparation, which includes choosing the correct machine, preparing the paint, isolating the area to be painted and protecting the painter's airway, is the key to success with a paint spray machine.
Step 1: For the project, choose the right spray paint machine.
Professional painters use airless spray paint machines for most paint jobs.Woodworkers and automobile painters use air assist spray paint machines because they leave the best finish.They are the most expensive spray paint machines.Electric cup machines can be difficult to use and are often purchased by homeowners for small jobs.They require that the paint be thinner.
Step 2: Get advice from your paint supplier about the kind of paint you need, and whether you will need to thin it with water or paint thinner.
If you want to know if your paint is thin enough to use in your spray paint machine, you should get a viscosity tester from the supplier.
Step 3: If you want to pump pressure, select your nozzle or tip.
Small nozzles and lower pressures are the best for thin paints.Large nozzles and high pressures are needed for thicker paints.
Step 4: It's a good idea to practice on scrap wood.
Hold the sprayer to allow the paint to exit horizontally and maintain a consistent distance from the surface.Move the sprayer with your arm and keep your wrist stiff.To paint ceilings, use a tip extension.If you're left-handed, you can spray from left to right or right to left.3 feet of paint should be laid down at a time.The surface will get 2 thin coats and won't dry into stripes of paint if you overlap the next application by 50 percent.
Step 5: Attach tape and plastic to the area you want to paint with drop cloths.
If you don't want it painted, cover it.If you use a spray paint machine, the paint droplets in the air will drift away and settle on objects nearby, including plants, decks and cars, if you are painting indoors.
Step 6: Keep paint out of your eyes and lungs by wearing coveralls, gloves, a hat, eye protection, and a respirator.
Step 7: If the paint isn't going on evenly, adjust the pump pressure or nozzle.
