Powder coating @ home: mess & smell?
 
Hey guys,

My brother just picked up an oven today to start powder coating with. My questions are how messy is it to spray the actual powder in a garage let's say, and when baking the parts inside the garage or basement will the fumes be too nasty or harmful. He is hoping to keep the oven in the basement around where the dryer is (for the 220v receptacle)

How are you guys set up at home to do this?

Thanks!

George

i don't think i would recommend in the basement. i have an electric ketchen oven in my garage to do powdercoating with. i mounted the oven just below one of the sliders in the big picture window on my back wall and a box fan in front of the slider. when baking i just open the slider and turn on the fan and all the fumes just go out the window.

you will have powder that won't stick to the part (s) , "overspray" if you will, it's nothing a few sheets of newspaper spread down won't handle. just wad em up and throw em away when your done... :thumbup:

I do it in my basement garage, it's good to have ventilation if your doing a lot of big parts. It's not as bad as spray painting though. The thing I found was turn the air pressure down works best. You literally want the dust to settle on the part, not blow it on. If you blow it on, it just blows material off.

arrowhead, it's not ANYTHING like spraypainting, you attach that - clip to the part you are spraying-- the powder at and the gun puts a + charge on the powder so it is attracted to the - steel part. most of the powder ends up on the part. the trickey thing is to get the part in the oven without any of the powder falling off. i find it helps to preheat big parts in the oven before you even spray them--but be advised, handling parts at 400 degrees can be detrimental to your hands... :D

OH, by the way, you are right. i spray at like -1LB pressure. the powder just floats out of the gun and gets sucked onto the part. if you get too much powder on the part the excess just falls off.

The "spraying" part of the job isn't particularly messy or smelly. As noted above, some of the powder will end up on the floor but easy to broom or vacuum up. So I don't think there's any problem doing that part in your basement.

The baking, on the other hand DOES have an obtrusive odor. I don't know that it is particularly harmful but I can imagine it would linger in the basement and get into the rest of the house with ease. Not something the wife and family is likely to be pleased with.

If at all possible, I would recommend installing your oven in the garage and doing everything out there. Just a lot less hassle.

hi cboy, the smell is not harmful, but it is sure annoying. the wifey will surely kick you out of the house (if you have one--not house but wifey,luckily i never got one of those--too expensive) and kiddies--DON'T BAKE POWDERCOAT IN YOUR KITCHEN, YOU WILL REGRET IT!!! :D

Like the others have said its the smell is not that bad. I have used a small toaster oven for small parts and it worked out great - I also have an electric oven but haven't graduated to doing big parts yet ;) I have the Harbor Freight setup and it works well for what I have tried.

techron 03-19-2008 08:54 AM

hey 66 chevy, i use the HF gun too. it's the same as eastwoods but cheaper. try a kitchen oven instead of a toaster oven. you will love it. the only thing that makes me mad is you can't do really big parts like rear axel housings or tube axels--they won't fit in the oven... :D

here is a tip: preheat big parts in the oven before you spray the powder on. make sure the parts are clean (i usually bead blast them first) ... :D

EDIT: also i buy my powders, hi-temp tape, hi-temp plugs off ebay. there is a seller in utah (can't remember the name) that sells good stuff for cheap. just search (powdercoat) on ebay... :thumbup:

powdercoating
 
keep the ground wire hooked up when moving the item into the oven,hook the other end of the ground to the inside of the oven then ground the oven. to build a larger oven cut up two ovens,or build from scrach and use oven elements or infrared lights.I worked 4 years in this industry there is a lot of info about building your own oven,good luck.

powder coat
 
I was wondering,,,,,,, is a gas oven or electric oven better, or no differance, I would think the electric would be more expensive to operate.. :confused:

techron 03-19-2008 09:49 PM

thanks nissan for the tips, i have read articles on building bigger ovens.

awert -->ELECTRIC OVEN ONLY!!!! no gas ovens allowed!... :D

66chevystepside 03-20-2008 08:03 AM

Thanks for the info - I have picked up ome powder off ebay but will check out this seller as well. do have an electric oven at my shop for powdercoating, just haven't tried to use it yet :thumbup:
