My Downdraft Paint Booth Finished

[Big Daddy]

First started with a good blower, 273 CFM bought from acklands grainger $90.00

2nd bought $35.00 of plywood could have made it 15.00 cheaper if i had used MDF but it would have been to heavy

Finally the finished product,i ran out of aluminum duct tape so had to finish with the handy mans special duct tape will buy more of the proper tape when i make it back to hardware store to get solid piece of duct work , don't like the plastic dryer type that i bought

[Big Daddy]

not sure what i'm going to do about lighting if i'll use what i have or get some led or halogen pucks to mount inside

any suggestions

[Dr. Cranky]

Interesting set up.

I would use the best lighting you can afford, maybe a bank of flourescent lights.

[Harry P.]

Nice job... but why the pegboard on the back wall?

I'd go with a strip of those under-cabinet halogen lights (the kind that go under the upper kitchen cabinets).

[mikemodeler]

Looks nice and I like the pegboard idea, could come in handy when painting something that could be hung. Will be interesting to hear your take on how it performs.

As far as lighting, I am with Doc, get some lights that give you the proper illumination so you can see what you are doing.

[Rob McKee]

Nice job.I agree with Dr Cranky on the lighting.

[Erik Smith]

Nice and simple build. Looks good. I use multiple clamp lights like the one you have - three with 100w equivalent flourescent bulbs.

[Big Daddy]

Harry , the pegboard on the back is there if i need to hang something or multiple things to spray

Gotcha.

[Big Daddy]

Well i just sprayed my gmc wrecker and i am very pleased at how well it worked ,also this will keep momma happy as there is no smoking in the house but i usually do when i am in basement all i have to do is turn it on a bam no smoke or smell , yaaaa killed 2 birds with one stone

[Harry P.]

I'm not so sure that spraying paint while smoking is a good idea...

[Big Daddy]

no no i don't smoke while painting i'm just saying now when i'm building i can have one down stairs and not have to go out side

Thanks for posting this, it was very helpful

[diymirage]

looks very nice

i have a backdraft myself but am thinking of changing over to a downdraft, just because i always seem to be spraying at the very front of the booth

as for lights, the top of my booth is flakeboard with a square hole cut into it

the hole is just as big as the light fixture from my old aqarium and it has a larger sheet of clear plastic screwed underneath it

Nice job,

I hope that your fan being over in the rear corner and with a horizontal intake ( not really a downdraft) can draw spray from the far sides of the inner booth.

I would have placed the intake in the center back.

You will get better efficiency of removing overspray by placing narow baffles around the face of your opening.

3" - 4" strips of wood framed around the face will prevent overspray from rolling out of the booth.

Incoming air will be focused into the center of the box and any overspray attempting to roll out will be forced back in by the incoming air.

The upper baffle will also serve as a shade from lights installed in the roof of the booth.

Holding your pieces over on the left side of the booth as you spray will be the best way to allow overspray to go directly into the fan.

Is that a Foster's Lager hiding behind the vice??

[scalenut]

cadillac pat i thought about putting it in the center but with the 1/2 flange that goes around the air exit the blower wouldn't sit flush against back wall,,,and i was worried about not drawing all the fumes and paint away from front so when it was done this afternoon i sprayed my 77 wrecker, i placed it right at the front and with me spraying 4-5 inches from body the fan did a great job and sucked all fumes away so i know now that with it in the back corner it draws from the front with no problem

now with the baffles do you mean just like a 1x2 around the whole perimater?

[Big Daddy]

Scalenut

it's a dayton 1TDR3 from acklands-grainger it might be a different number in the us

[scalenut]

thanks BD , it's probably the same or very close

[Gregg]

My only thought is that with the bare wood, that's going to attract major dust and paint buildup over time.

Any way to cover it with the white formica thin sheets, or veneer?

I had that problem with mine, added the thin veneer and it wipes clean after use.

Or does someone else have ideas?

For my old metal one, I would love to have white powder coated, but don't know if can wipe powder coat down with lacquer thinner

Daryl, I like the way this one turned out.

[Harry P.]

Self-stick saran wrap. Forgot the brand name. Would it stick to bare wood? Might have to paint the inside of the booth with gloss paint first.

[Big Daddy]

yea thats next weekends job is to paint it i got all kinds of white gloss here

[crazyjim]

How did you convert the square flange to round to accept the dryer duct?
