Spray Room Size

[Guest]

Well as we get closer to finishing the build on the big oven I'm starting to look for spray solutions to keep the powder from going everywhere and contamination free.

I'm looking to build a little bit more than a booth, I actually want to dedicate a small room to just coating. The oven is 6x4x3 so obviously that's the minimum size I can build. Then it has to have enough room for to fit inside of it and actually coat.

I'm thinking of building something close to 8x6x4 (internal size) What do you guys think? Will this be big enough to work comfortably on most small parts?

Let me know what you think... Thanks!

Re: Spray Room Size

I'm thinking of adapting my booth into an enclosed area about that size too. Right now when I coat a frame, powder goes everywhere because my booth is on a stand 3' off the floor. I'm basically going drop it down and wall it in, shaping the sidewalls like a funnel so the powder draws in to the filters.

Re: Spray Room Size

That's basically my biggest fear, building a booth and then finding out I'm still getting powder everywhere. I would rather build a slightly bigger box with some nice lights, couple of fans on the ceiling with filters for ventilation, a wall mounted vacuum for easy clean up, and sealed well enough to keep all the powder in and the dust out. After doing some more measuring last night it seems like 8(h)x6(w)x4(d) wouldn't be too bad. I think 5 feet deep would be perfect, but we'll see how that plays out during construction.

Re: Spray Room Size

Here is mine when it was under construction......it is 7'x8'x8.5'h I can move very freely in it. It is directly across from my oven door so I can have the minimum distance between the booth and oven. I also have a overhead rail system set up for it now.

Re: Spray Room Size

Shawn, that's exactly what I had in mind! Obviously in a slightly smaller scale.

Care to explain how the ventilation/dust/powder removal works with the 2 filters? I had the same thing in mind using a couple of filters and fans. Does any powder escape the booth through the filters and fans?

What did you make the walls and door out of? I priced out some materials last night and it seems most of the 8x4 panels run about 8-10 bucks, while dry wall is 6 bucks.

Any more pictures of the finished product? That's really close to what I'm looking for. Thanks man!

There are actually 4 filters there they are two deep and after almost a year I have had no evidence of any powder around the outside of the exhaust fan. I started thinking I could have two "box" fans behind those filters but as soon as I turned them on the first time I realized it was no where near enough so I took the box fans out and installed that whole house fan (1380 cfm) and it works good. I also put it on a dimmer switch (on the left of the filters) so I can slow it down when needed. In the last pictures you can see the set of inlet filters up high behind the door.

I used heavy plastic sheeting to seal the walls ceiling painted the floor with epoxy floor paint then installed melimene (sp) panels...I still havent finished all of the panels yet lol been to busy.....

It sounds to me that you are adding 1 ft to each side and 1 ft to the depth of the rack. If you have a means of rotating the object on the rack then that would be no problem, but if you need to move around the rack to spray, I would think that you would need more room on each side. If it was me I would just double to size of the rack to allow plenty of room to move around the rack. I would use dimensions (assuming the 6ft is the height) of a 8 ft ceiling and 8ft deep by 6ft wide minimum. This would give you 2ft of room on each side, 2 ft on the back, and 1ft at the front to work with. If you go 8X8X8 you will eliminate a lot of cutting of materials also.

That's a good suggestion. Part of the reason why I was trying to avoid going with anything bigger than 4 feet was to reduce the amount of material that is cut, using 8x4 sheets. Like you said, the same applies to 8x8.

The biggest problem is that I'm working out of a 20x20 garage, so space is at a premium. I still want to be able to park a vehicle in front of the booth. I measured the vehicle and it's 14 feet long. That leaves me 6 feet to play with and no breathing room to speak of, kind of tight eh?

Re: Spray Room Size

Here are some more pics of the original design before the big fan.....the nice thing is I can slide that window shut when I am not using the booth.

Rotating the part:

That's part of the plan. I don't want to move around the part and I don't want to move the rack, I want the part to rotate... I saw those swivel hooks you posted a while back and I've been trying to think of ways to implement them ever since.

Re: Spray Room Size

Here's a pic of my spray room and box fan vented outside, I believe it's 6' wide x 6' deep with an open doorway. The rolling rack barely fits thru the door, but like you at the time I was still parking my old truck in there and was tired of all the powder on it. Most of the powder stays inside the room area, but some will get tracked out if you don't clean the floor regularly. I just changed fans, the old one died from powder buildup in the motor wiring. It lasted a little over a year I think.

Re: Spray Room Size

Nice booth man! 6x6 looks like a very good size, I can't wait to go home and see what I can figure out. How does that single fan work out for ya? Obviously not too bad if it was killed by the powder lol...

Did any powder ever escape past the second filter?

How do you think two of the same fans would work on top of the room. My garage has close to 14 foot ceilings so I would like to mount them on top of the room. I wonder if they would be enough to pick up any powder.

Re: Spray Room Size

The problem with the top mounted fan is you'd be fighting gravity. It would take quite a bit of force to suck the powder all the way up cause it wants to fall down. Here's mine..

Yeah I have eliminated the top mounted fans because it just doesn't make sense... I would have to basically create a vacuum at which point it may have negative impact on my actual coating.

A booth like yours is what I originally had in mind... I just want to keep all the power away from the rest of the shop.

What are the dimensions on that booth?

Re: Spray Room Size

48"w x 36'd x 84"tall I run 2 filters and it works pretty well. My plan was to make it big enough to have some shoulder room and make it easier to turn the parts. I was going to run a second fan but I think I'm going to replace the original with some sort of exhaust fan vented outside.
