Proper Spray Paint Gun Techniques Explained
Spray painting is a painting technique wherein you can paint any surface with a spray paint gun. A spray paint gun can be either manual or automatic. Manual, naturally implies, that you will have to manually move the gun evenly over the surface to be painted. An automatic gun is stationery, and it is usually mounted on a block from where a uniform stream of paint will be sprayed onto a surface. Spray painting is pretty easy to master. As for the amateurs, here are a few techniques that can help make you a pro.
- Your first task is to attach the compressor system as this will allow you to regulate the air pressure and correspondingly the volume of paint.
- Try and ensure that the furniture or object you are spray painting does not need too much of repositioning. If you are painting a chair, keep it elevated, that way you can access all parts of the chair without moving too much.
- Your spray gun should be held perpendicular to the surface being painted at all times. When spraying a large surface area, keep your head still and move the gun in a straight line across the surface, i.e., move your arm in a steady sweeping motion.
- Even if you have set the compressor appropriately, in order to achieve an even distribution of paint, ideally start spraying roughly five to six inches before the surface and ease pressure on the spray gun six inches after the surface.
- You can adjust the size of the spray gun’s fan. So, for a large surface area, adjust the gun to the widest fan as this will reduce the number of passes. Also, if you are spray painting a large surface, hold the gun at least 6 inches away from the surface. For small surfaces, hold the gun closer to the surface and select the small fan.
- Spray painting is very different from painting with a brush. Even so, try to move the gun at the same speed as you would a brushstroke. It sounds difficult, but after a few attempts, you will be able to alter your speed quite naturally to ensure even distribution of paint.
Tips and Warnings
- Ensure the surface you are spray painting is clean, free of dust, and most importantly, dry.
- If you intend to spray paint anything outdoors, take stock of the weather. Humid weather is not good for spray painting, and if it is windy and/or dusty, do not spray paint outdoors as the dust could get stuck on the wet paint. Ideal temperature range for spray painting is between 60° F and 90° F.
- When you begin spray painting, keep your arm moving steadily, if you stop your arm movement, without releasing pressure on the gun trigger, you could end up with uneven shades.
- Once you are done spray painting, turn the can upside down and press the gun nozzle. You can do this until the last of the paint is out.
