New Paint Gun? Not Sure What To Do Next?
This Quick and Easy guide is all you will need to start painting your project in no time, you might be surprised just how easy it is.
To start things off there are a few pieces of equipment you will need before you get to painting. These items are required and you will not be able to continue without them.
In addition to your new paint gun you'll need:
- Air Compressor (Preferably one that exceeds the minimum CFM of the paint gun)
- Air Filter, this can be a disposable or Wall Mounted Unit (This will make or break the overall outcome of the paint. Even a little moisture or oil can ruin the paint)
- Gun Mounted Air regulator
- Lacquer Thinner (Used to clean the gun after Painting)
Shown here in the picture above is the EW Concours Pro (left) and EW Concours Paint Gun (right). These paint guns share the common controls found on almost all HVLP paint guns on the market, from discount tool models to industry elite brands these tips are relatively universal.
Air Fitting and Regulator
Now you're Ready to set up the gun. Depending on which paint gun you have, it may not have an air coupler attached to the bottom. All you need is a little teflon tape (found at any hardware store) wrapped around the threads. First screw the regulator to the gun then screw on the air fitting to the regulator. Tighten using the supplied wrench which comes with most paint guns. This will ensure an airtight seal to the paint gun.
!WHEN WRAPPING TAPE AROUND THREADS REMEMBER TO WRAP CLOCKWISE, THE SAME DIRECTION THE THREADS TIGHTEN. IF REVERSED THE AIR COUPLER WILL UNWIND THE TAPE AS IT IS SCREWED ON!
Setting Air Pressure
Next you'll need to adjust the air flow to the gun. This is where the gun-mounted regulator comes into play. On the box or in the manual of your gun there will be a recommended pressure the gun operates most efficiently. (ex. 30 PSI) Completely open the air flow adjustment on the gun and do not touch it, from now on the regulator will control the air flow through the gun. After your compressor is turned on and filled, connect the gun without the paint cup attached. Pull the trigger completely open while monitoring the reading on the regulator. You will need to adjust the regulator to match the recommended pressure for your gun. (ex. so the regulator reads 30 PSI) Now that you have set the regulator unhook the gun.
Fan Size and Fluid Adjustment
This part can be tricky since the material you are spraying dictates the how big the fan size should be, how far away to hold the gun, and the correct overlap. Look to the packaging of the material you will be spraying to find the recommended values. As a general tip, open the fluid adjustment all the way so the trigger can be fully engaged. If you are worrying about running the paint turn the fluid control in and slowly bring it back out as you get more comfortable spraying.
This also depended on the material being sprayed but generally the mix ratios are printed on the container or packaging of the material you will be using. Attach the paint cup, pour in the paint, and seal off the cup. You're almost ready to paint!
Remember to attach the paint cup and pour the paint into gun without the air line attached. It is easy to bump the trigger and accidentally spray paint where you don't want it.
Attaching the Air Line
After the paint is in the gun and the lid is on tight you are ready to attach the airline and get to painting. Make sure you have a panel or piece of cardboard to use to test the spray pattern. This is when you will use the fluid control and the fan adjustment to get the desired pattern for the material.
Get to Painting!
There you go now you can start painting all of your projects with you own paint gun. At first it can be difficult to remember to do all of the steps in order but it wont take long to become second nature.
Cleaning you gun is just as important as setting up to paint! All you need is an empty metal paint can and Aerosol Injected Cleaner or lacquer thinner and its that easy.
After you are done painting detach the gun from the air line. Then empty the paint cup into the paint can. Now using Aerosol Injected Cleaner, a Solution Bottle filled with thinner or (I'VE FOUND THAT A CONTACTS SOLUTION BOTTLE WORKS), hold the paint gun over the paint can with the trigger pulled and pour the thinner into the gun where the paint gun attaches. The thinner will run through the gun and out the nozzle. Continue to pour thinner until it comes out of the gun clear. Make sure you clean the gun immediately after painting so the paint does not dry in the gun.
