    Default Paint Booth

    I will be using Stewart Systems and am building a 12' x 24' booth which will be inside a heated building on a epoxy coated cement floor. (I hope to be done painting before it gets cold here in Michigan this fall)

    I purchased four 20" box fans and good quality 20" x 1" filters. I will use clear 6mil plastic to cover the booth.
    I will enter and exit through the end of the booth with a large zippered door.

    I purchased a FL4 gun, regulator, filters, large flow quick connects, respirator, new hoses, tyvec suit, etc. all per the Stewarts overview video. I plan on cooling the air between the pump and compressor tank a la Troy in his Stewart paint posts (thank you Troy!) I have plenty of air with my 5hp two stage compressor.

    I should have plenty of light with the shop converted to high intensity 8' LED tubes in the fluorescent fixtures. I also have six 4' led shop lights to use ?vertically spaced in the booth.


    Paint Booth questions:

    1. What is your recommendation for air flow? Should I try for neutral pressure with two fans blowing in and two sucking air out? or?...

    2. What to do with the floor? Just wet it when painting, or cover it with butcher paper, or?...

    3. Things you would have done differently, or suggest I do.

    4. Anyone need a paint booth when I'm done??

    Thank you,

    David

    I only sucked the air out. I had 2- 20" fans and only ran the one. I had the other ready to turn on as a back up. The booth cleared quickly. You could experiment, positive air in the booth will keep dirt out. It was never the booth for me though, it was the quality of the surface prep for the best results.

    The key is to keep the floor fairly clean but more importantly doing an extremely good job at cleaning the surface before top coat. 3 tack rag runs min.

    Make sure your booth is plenty strong to support the pressure. 2X4 was way better than conduit. Make sure you are using the proper paint filters for both incoming and exiting air.

    Good advice. Another thing that helped me was to use a blower (like a yard blower) and I blew everything in the booth down very well first after wetting the floor (so the dust would stick to the wet floor). I did this with the exhaust fan on so it pulled dust out as well. This made a HUGE difference in the very fine dust that I was getting onto the horizontal surfaces. I did this just before I started spraying. (maybe 15-20 minutes before but I never turned off the exhaust fan). Tacking RIGHT before spraying like Troy says is a must.

    Very nice advise. I did this and it worked for me. Thank you!
