An air compressor is a versatile air tool; you can use it for spray painting, nail and staple guns, tires, and more. If you are planning to use a compressed air paint sprayer, you need an air compressor. And to use it correctly, you should read this.
Using a compressed air sprayer can be confusing since most of these paint sprayers are connected to an air compressor. Fortunately, there is an easy and correct way on how to hose the air compressor for spray painting.
#1: Preliminary preparations
Before preparing your air compressor, you need to prepare the basic painting materials and tools; these include:
- Select the paint and the thinner you need to use for spray painting.
- Prepare your working area to avoid the mess in case of overspray.
- Prepare on your safety goggles, mask, and gloves.
- Prepare the surface that needs to be painted. You may add primer if necessary.

If you have a new air compressor, here are the steps on how to use it correctly:
- First, you need to turn on the air compressor; this will help build up the pressure that is needed for the compressed air sprayer to release the paint.
- Set the pressure correctly via the regulator to avoid fluctuations when spraying. To set the regulator you need to adjust it between 12 and 25 PSI, depending on the number of the paint sprayer you are using. To find out, you should check your sprayer’s manual for instructions.
- Attach the hose of the air compressor coupling to the sprayer and make sure it is tight; this is to avoid any possibility of hose and sprayer displacement and to avoid reduction of pressure. To secure it an airtight seal, you may wrap it with Teflon tape. However, if the sprayer and the air hose is equipped with quick-connect coupling, you do need to secure it a tape.
- Add a small amount of paint thinner as instructed at the sprayer gun’s paint cup.
- Slightly open the metering bulb.
- Test the sprayer. It may take a few squeezes to get a flow of the thinner. However, if no thinner comes out, you need to disassemble the sprayer to check for possible loose seals or stoppages.
- After the primer, make sure to empty the spray cup from the thinner you have used earlier.
- Prepare and fill the paint cup with the paint. Make sure that all screws and hooks are secured.
#3: Paint the right way
To have clean spray paint results, you should know how to spray paint the right way. Here are a few steps how:
- Hold the paint sprayer about 5 to 10 inches from the surface you want to paint.
- Squeeze the trigger with movements (horizontally and vertically) to avoid drips and runs due to over-application.
- Overlap each spray pattern to ensure the evenness of the paint.
