I’d like to build a spray room for finishing furniture. It would be constructed out of thick clear poly with the seams sealed with duct tape. The whole thing would be pressurized by a fan with the exaust passing through a filter.
When work in the room is completed I envision it folding up like an accordion and being stored away up against the ceiling. A series of pullies could draw it up and secure it.
Is this going to work?
What should I consider for a fan size, exaust size, filter type etc?
Thanks in advance.

Sounds like you are planning on having the fan blow INTO the booth. It usually draws the air out. blowing unfiltered air into the booth will cause lots of dust contamination in your work. If you do filter the incoming air you will still have to spray in hurracaine force wind conditions.

Spray booths have exhaust fans and it sounds like you want a spray room. If you enclose the whole area, using an exhaust fan with a filtered fresh air supply vent should work as long as the supply can make up for what is exhausted. Otherwise, the poly sides will draw in and if the deficit is great enough, seams can fail.
Another consideration would be the residue on the plastic walls. If you fold it up before the lacquer dries on the plastic, you may wind up with a permanently collapsed paint booth.
Just did this in the last month and it works great. I opted away from the acordian idea...just made the poly removable. Only downside I have found so far is that the overspray does not stick to the poly when dry, so it ends up being messy during take down...maybe this is a case in favor of the acordian idea. :)
Hope this helps.
p.s. I was very surprised how much paint ended up on my respirator fiters even with the exhaust fan going. I would not go in there without a proper mask on.

It may work but not as well as creating a vacuum by drawing the air out of the enclosure. Air moves by pressure better than by force. Creating a negative pressure will give you an even controlled flow in the "room" while blowing into the room makes the air circulate somewhat wildly with eddies and currents affected by both you and the other objects in the room. Add a filter wall to the side of the room that the air comes into and you will be a happy camper (sprayer). aloha, mike
Andy,
Send me your e-mail address and I'll provide you instructions on how I made my folding spray booth. I've also got a materials list and a photo of it in use. All for free, too!
