I have seen the question " how do I build a spray booth " posted countless times, so I decided to post some details on my booth. This write up is intended for all the powder coaters out there who want a effective booth that will not break the bank. While not perfect this design has served me for over 2 years with no problems to date. I use this booth for both powder coating and liquid paint applications. This design is made to vent to the powder to the outside of the building. I use a watter trap to catch the powder after it exits my shop. Lets start with the major materials needed in this project:
1) centrifugal blower fan. (I got mine from a old "jumpin gym" inflatable toy.)
2) Box fan
3) some 2x4 lumber and 4x8 SMOOTH wood panels. I stress the smooth part as this makes it easier to clean. Dont use USB here or you will regret it later.
4) lights for the booth
5) Wiring and switches to control the lights and the ventilation system.
6) A case of your choice beverage.

Above is the rough design of the booth I made with microsoft paint. It is not perfect or to scale but it keep me on track during the build. Lets start with the side view. The box that is attached to the rear of the booth is used to catch the powder that the box fan pulls it in from the booth. Now that the powder is confined to the small box the centrifugal blower can now effectively capture the powder and discharge it to the outside.
Now on the the front view. Take your box fan and remove the guards from both sides and attach the metal frame between the booth and the box on the back. Make sure you have the fan facing the right way so it is not blowing the powder back at you
. The rest of the booth is pretty much stright forward. Just some basic electrical and carpentry skills and you can have it build in a few hours.
These were just very general instructions. If you have any questions please feel free to Email or call me anytime and I will be happy to walk you through it. I have included some pictures of the finished product below. Its not pretty as it was made from used lumber but it works great. I hope this information can help someone out there.


I will also be posting a write up on how to make a dust collector out of your shop vac. This comes in handy for cleaning your powder booth and/or pulling the dust from your blast cabinet. With this design you will never have to replace another shop vac filter and there will be no dust blowing out the back of the shop vac to ruin you finish.
