View Full Version : Spray booth venting

Hello all,

I have finally had enough of dullcoat fogging due to high humidity ( 4 times this summer! ) and think it is time to invest in a spray booth so I can stop painting in the garage and go down to the climate controlled ( and dehumidifier equipped ) basement.

So here is the question I have for today.... for those of you who have installed a spray both in a basement, how have you vented the exhaust?

The layout room only has one translucent block window, so venting out the window isnít an option. I think that means the only real option is installing a dryer type vent into the wall above ceiling level ( just like the dryer is vented in the adjacent laundry room... ). Has anyone gone through the process of doing this? Is there anything I should watch for? ( I have a whole saw of the right size for a dryer vent, so tool wise I have what I need for the project ).

Secondary question, who makes the best current production spray booth? I havenít decided if I am going to build or buy yet.

Thanks,

Paul

I think you're on the right track regarding ductwork. It's pretty simple to install as long as you have a way to get through the wall. I put a duct through the wall to exit out the old coal door I sealed up (except of course, the hole for the duct) in my old layout room, but never got around to building a spray booth!

A search of the subject of homemade spray booths will always seem to revolve around the fan and fear-mongering about fume explosions. General concensus is a bilge blower fan is a pretty safe option for evacuating fumes. they are readily available and not too expensive. In fact I just saw one at Wal-Mart the other day but I didn't notice the price.

Clear plastic totes are popular to make the actual booth out of as you can shine a light right through it and they're relatively inexpensive.

I use this carbon filter. Connects to the standard dryer hose and no smell at all. I have been using mine for over a year now with intermittent painting using airbrush and rattle cans.

This what I have, I vent it under my garage door. All you would need is crack the window open and put the vent hose out of the window.

Looks interesting for those like me where venting to the outside will be difficult. What do you use for a booth and exhaust fan?

I built my own spraybooth and used a marine bilge blower. Works great! I'm at work tonight but if you'd like I can post up the sketch and pics, just let me know.

Yes, please do.

Now I need to figure out how to get a ceiling panel detached in the train room ( it isn’t a drop ceiling, but it is some kind of paneling with wooden edge strips....)

Using the plans from plans 2, I created a template with scarm for the sheet 1/4" plywood I had. The bottom is a piece of 1/4" foam board. I soldered up 7 LED strips from a 16' roll I bought off of Amazon. The blower motor is a marine grade bilge blower 12v. The air filter is a 20X20X1 that slides in from the top. These pics were taken when I first finished the booth. I still need to clean up the wiring and decide how to secure down the top but I've used it heavily since finishing the build and it works great.

Here's the links to the LEDs and blower:

I use two of these rocker switches, one in red and one in blue, to control LEDs and blower independently.

I can take more pics if you'd like.

Is there access to the end joist above the sill plate? In my area, NJ, you can go through there and still be in code. (Edit - Unless that is what you are planning)
Less work than going through to a wall above. Just need to keep 10 feet from a gas meter, certain distance from propane tanks, septic, etc, in case of gas/fumes getting back into your vent and into living area.

just something ive noted through out my times. basements need a vent from the floor to the out side world. if you use any kind of flammables down there the lingering fumes can and will ignite and boom there goes the whole house. just a note to you guys with basements. kinda like boats boats have vent fans exhausting the gas fumes from the very bottom of there hulls to the out side. this is number 1 reason boats catch fire and also # 1 reason houses explode from flammable fumes. be safe with these areas. if you do install a vent try to also vent from the floor bottom.

love the spray booth and those leds are very bright .

Hmmm. Makes sense. I have never heard of a need to vent from floor level. Need to look that up. Although I don't have that many flammable fumes. Would have thought the spray booth vent would do the job...

That is more or less what I'm thinking. The adjacent laundry room has a dryer vent and a radon mitigation system going through that joist in the same way I was planning.

Ok, I'll have to check the distance to the gas meter before I cut the hole.

There is a new twist to this as well. I need to run a compressed air line from the garage into the basement. Fortunately, that should be relatively easy, since a wall in the train room is near the garage (still have to go through the joist there, but there is already a hole in the wall for an unused coax TV cable where I want to put it.)

im very paranoid about any level below surface look at mining they always vent or force air into the depths.

When you use this filter is there a need to vent it outside? I plan to use only acrylic paints, rattle can and airbrush.

Oh, I like that. And no requirement to cut a hole.... hmmm... I might just have to make that something like that my next major purchase. ( I notice they also have a smaller booth of similar design:

I would get a little closer to the face than the guy in the picture.

Add a quality dryer hose and a couple of clamps to the filter and no dust or fumes.

You were right Andy. I bought my booth and carbon filter posted here: http://www.nscale.net/forums/showthread.php?45112-What-are-you-buying-this-month-(August-2018)&p=541732#post541732

I tested it by spraying one of the strongest of fumes I have used (Dullcoat) and there was barely a hint of odor.:thumbs-up:

Didn’t notice any dust when I tested it. Do you have any idea what the black strap that comes with it in the box is for?

I use mine to hold the fiber blanket in place.
