Firstly, you will need to seal off your working area, ensuring that all surfaces within six feet of your work site are covered. To do this, use plastic sheeting to seal off passageways, doorways and floors you do not wish to get paint on. If removing everything from your work area is not possible, put all moveable objects into the room’s center and cover your pile with plastic tarp.
Now, cover your body, unless you want to be covered with paint at the end of the job! Cover yourself with a light and disposable jump suit made for painters, worn over your regular clothing. Ensure that you wear gloves, preferably rubber. If you own stocking caps, cover your head with one, or else your hair will be covered in paint. Finally, you will need to wear safety glasses or swimming goggles as well as a nose and mouth mask for safety, as paint droplets can wreak havoc on the body’s insides.
Now, test your paint’s viscosity using the tool that came with your paint sprayer. Paint that is much too thick clogs sprayer nozzles, so use water to dilute your paint until your testing tool gives the indication that the correct thickness has been achieved.
Before you use the paint sprayer, test it outside, where it won’t matter if you ‘fire’ incorrectly. Choose a practice target that is similar to what you are actually going to paint – so, for example, if you are planning on painting a ceiling, spray your paint gun overhead, and if you are going to be painting a wall, spray the gun on a wall outside.
In many cases, you will need to wait a couple of seconds before your gun starts ‘shooting’ properly, as they can take a while to start up. It is best not to get the results of this ‘start up’ on what you are trying to paint. The gun will sputter, meaning that you should try to practice using the gun somewhere other than on what you are trying to paint.
Now, use the gun for about five minutes. Once this time limit is up, stop and review your work. Should your paint be running down the wall, you have most likely diluted your paint too much (assuming you are already moving the gun instead of keeping it still – if not, this is your problem).
