Didn’t read every post in this thread so maybe this is a repeat but please, please, please wear a high quality mask, the kind rated for fumes, when you power coat. Extremely fine plastic powder is very bad for your lungs. It may remain there for the rest of your life.

Hydrochloric acid or pool acid (same thing) will take it off in seconds… just wash and dry straight after ( will flash rust ) then blast. I do it all the time…

Like dfreyfbn said… fumes are horrific, never do inside! Well ventilated area and make sure you have clean water right next to you in case any gets on your skin.
Figured I’d put this in the PC thread, funny BUT not funny more so informational (or a story to learn from my mistake).
When I first started PC’ing probably 15 years ago, I was doing it in a small garage. One August day (recall the day like it was yesterday) I had to do a couple quick parts. Opened the door, didn’t have a containment system or booth yet. The vacuum pulled powder lingering in the air out of the garage, that was fine, as I’ve done it before. Got the brackets in the oven and cured, looked fantastic! They still do to this day. What did NOT look fantastic was my truck sitting in the driveway that was baking in the August sun. Yep, had a 2006 2500HD crew cab that was also PC’ed. 2 days, 3 clay bars and a case of tennis elbow later all was better.

I have the same experience. I also powdercoated in my garage without a booth and depending on the weather with the garage door open. Both of my cars parked outside their windshields and paint had a sandpaper texture from the partially sun cured powdercoat. Worse yet was everything in my garage had powdercoat dust on it. Rubber and plastic items the powdercoat embeds itself into and is nearly impossible to get off. Hoses, electrical cords, plastic or rubber hand grips vinyl upholstery material. I had and old car with a white convertible top in the garage, I haven’t found anything to remove the stray powdercoat dust. It’s no joke, it drifts a long way and the desert heat in Las Vegas is enough to at least partially cure the powdercoat.
Along this line, I never user silica or sand. I use washed coal, “Black Beauty”, from Tractor Supply. It’s about $8 per 40 pound page and comes in 24 grit. It doesn’t last as long but does not produce silica dust.
Hell ya!!! I am looking into building one similar to that size soon. How much do you have in just building the oven, minus the controller.
Not cheap to be honest. I am based in Australia so material prices would be different but I would say maybe $3000 AUD without controller.
There is over $1000 AUD worth of insulation in the oven.
Mine is actually a fully welded frame clad in stainless steel inner, 50mm ceramic fire blanket insulation then ally checker plate outer…
The designed changed as I figured out certain things would not work etc…
The heat soak from 200 degree temps is the biggest challenge.
My biggest advice do not cut corners and do not try and do it on the cheap side !! You will pay for it later down the track.
That is pretty BA! Nice job.
That purple looks like the same purple i used about 6 months ago. I cant remember where it came from but i do remember it reacted different than my other powders. Nice work
Ive been diving into powder coating. I have a redline ez50 gun, homemade spray booth and old house oven. Planning on building a booth and an oven that will allow to powder coat up to the size my table will cut. For now, about 19x22 inches is the max I can fit in my oven. I’ve been experiments with different colors/combos. This is my favorite so far, its Gold Medallion base with Disco Lemon Drop from Prismatic Powders

I like the idea of building a oven. Weight the cost of building one. I ended up buying one from light armor. Very nice ovens

Im looking to build one that is 4ft wide 4ft deep and 6ft tall. Its been frustrating to have to either try and fit parts in the regular house oven I have or not even having the option to powder coat because my project is too big to fit. A question though, it appears as though I will need between 10k and 15k watts for the space I’m planning. Is it possible to use say 4 3600 watt heating elements from a household oven wired together? Im hoping the wiring I installed for that outlet will be sufficient. I have an approximate run of 40ft with 6-3 on a 50 amp breaker.
If you build a oven that large. I would recommend a circulator fan to keep even heat throughout the oven. That will eliminate cold spots. Most commercially build ovens have them.

You’ll only get 12KW on a 50A breaker.

I am not sure the wattage on my oven I will have to go look or do the math. I have a commercial build oven 4x4x5 with 4 elements and a circulator fan. The amp draw is 44 amps when wide open. It does make my power bill go up.

youtube and the overall web search show many home built PC ovens being built…
If you increase the insulation value of your oven you ll be able to reduce the overall amount of elements you need and reduce the overall power usage.
it is, but you will want sequencers to stage them on one by one .
Some thing like this.
