Would like some feedback on paint booth design

[baggedcobra]

I'm starting construction on Saturday and building a 8ft x 10ft room off the back of my shop. It will only be used for painting. I'll be putting 18ga galvanized sheets on the walls and ceiling. My main concern is the intake/exhaust. Here's a basic layout of what was recommended to me by a friend who has some booth knowledge. The intake will have no fan. I would just like some other opinions. Thank you

Exhaust Fan I'll be using...

Booth design...

I'm certainly no expert, but I believe there is some 'recommendation' for sizing the intake filter square footage area to the CFM of the exhaust fan to maintain the proper flow/pressure inside the booth. Hopefully, someone here can educate the both of us. lol

Yeah definitely. That's the kind of feedback I need. I have searched all over the Internet. Most people building their own booth use box fans, PVC, and plastic. It's difficult finding an actually room turned into a permanent booth.

I would place the intake opposite of the exhaust for cross-ventilation. Overspray may linger in the air near the corner where your door is.

If the overspray lingers longer than your paint takes to flash(which can be quick in warn weather), it will dull the finish when it settles on the freshly painted surface and only half way "melts in".

That was the original plan. Only reason I changed it to exhaust out the back is that there is nothing but woods behind it. To the left and right I have neighbors. Granted they are not real close as I have a 2 acre lot.

http://finishingacademy.com/training/aero/aero_mod3/aero_mod3_intro.html Take the intake air from the top and from the existing builfing, this is warm, you can heat if needed and put the fan down low on the outside. Makes for a down draft. Open the walk door to the existing building to make up air, limit the intake air till there is a draw on the booth. That is a lot of fan for that, **** your socks off in that little room.

What is on the walls now and does the back wall already exist? Cut hole and install a couple furnace filters. My get up is super fast and the down draft is right on, if you tune it would barely get anything on the walls.

Many temp setups are expensive, they take up space, are slow and cumbersome to rig. I have done this several ways, seen a few more back in the day. By the time I got to this scheme I had it pretty well figured out, I can be ready to paint a car in about 10 minutes and same for demolition, super for rigging in and out and I use the space for other things 98% of the time anymore.

Thanks for the feedback. So you're saying to move the intake to the ceiling or to the top of the existing shop wall? And move the exhaust fan to the bottom of the back wall? I know thats alot of fan for the small room. I already had it so figured I'd just put it to use. If I could find a smaller, cheap alternative I wouldnt use that big fan.

also looking for lighting recommendations. I know explosion proof is recommended but not in my budget. I'm debating on building in recessed flourescent lights with plexi over them or just using regular flourescent lights mounted on the walls and ceilings.

maybe something like this...

Yeah I think mounting them flush is going to be the way I go.

I bought all the materials yesterday. Starting on the structure early tomorrow morning.
