Finishing Room Size2/19
Last year I moved my shop from my 600sf garage to an 1800sf shop. The plan was to have a finishing room in one corner. I never built it because I was not sure about how much room I needed for it and how much room I needed in my new shop. After working in here for about a year I still can't decide on how big to build it or wait until I have more room one day and build it then. We use the space now for finishing and when cabs are done they get put there and are out of the way. The biggest problem I have is with one other employee I need to finish when he is not working. We spray water base polys and precat lacquers and stains. Right now I have a large exhaust fan that can exhaust the whole shop in a few minutes but then its a challenge to keep it heated when I finish. We build alot of large 84-96" bookcases and some cabinetry etc. With a smaller finishing room, where do you put the stuff to dry you just sprayed without regularly going in and out of the finishing room. I could give up about a 12 x 12 corner if it were worth it and use a smaller exhaust fan?? What about finishing multiple large bookcases, then I need to constantly move them in and out of the room with each coat?? If you have a shop with a similar set up how do you do it?
maybe you can find a spray booth used for cars. you can remove panels so it is not so long.it is also easy to move if you move.
My spray booth is 8 by 8. However, I do almost all small parts, so you might need a different size based on your product line.
As far as moving the bookcases in and out of the booth, is it possible to put them or build them on a small wheeled cart like a furniture dolly. Seems that would make it much easier and safer to move them around like that.
Just a thought.
Thanks for the info. We have little cart tables we wheel our projects around on. We should build a few more. Now that I am thinking about it more maybe I am wondering more about the process. When you spray, do you let it flash off in the booth before moving it out so you can keep spraying others, so do you have something like a drying rack outside the booth? Sometimes I have 20 or 30 shelves/doors to do. Or do you move it out right away back into the shop and dry and bring more in? Or just go in, spray as much as you have room for laid out in a batch, leave (and make saw dust) and come back in 30-45 minutes later or whatever and sand those you just sprayed and re-coat those without moving that batch? I am sure everyone does it a little different. I probably need to have the booth made and start doing it until I figure out what works for me??
I have drying racks outside of the booth. I have a long cart in the booth for placing items on to be sprayed. Once the items are sprayed, they are placed on a drying cart out of the booth for drying. That way I can move quite a few items through the spray process. Once they dry, we sand and repeat the process. While the items are drying, we are doing other tasks in the spray booth such as painting and finishing of other items. If no work for the booth, the person moves to another area to help with other work.
I don't leave items in the booth to dry as we are constantly painting and finishing different items through the course of the day.
My product line is all small items so my work flow will be different than others.
I have a separate room off the back of my main shop, connected and we have a large 42" door for thru the wall. The separate room is overall 24' by 12'. This room was divided by a stud sheetrock wall with air vents cut along the top, 12" down along the entire 12'. The vents are covered with filter fabric to allow for clean air. As you leave the main shop, first area is for light prep work and then for holding product after being sprayed. Then you enter the spray area thru a pair of 30" double doors.
first off you have a very small space dedicate to finishing, having rolling racks and carts can help with moving parts around and out of the way. Regarding your exhaust fan you should install a Variable Speed Control on the fan most electricians should be able to assist you. This will help with maintaining a warmer shop..
Mine is 18w x 24d x 9h.
I have a 8d x 12w drying room, wish it was bigger.
The spray room is 16d x 18w and there is an entry hall that is 8d x 6w.
This hall area is behind the intake air and is in a "safe" area because no spray can get there. So I use it as a staging area for the next cabinet.
One of the things I screwed up on was making my doorways 7' tall instead of closer to 9' which is ceiling height.
All great info folks! Thanks. Really got my mind brain storming it. Sounds like my idea of a finishing room will be a bit cramped but it might be worth having it anyway. I may have the option to expand and get more of the building in the future (lots of building here). I like the idea of a drying room but no way we have room for that yet.
