HOME POWDERCOATING 101


Recommended Posts

Please give any information or tips & tricks about powdercoating in your garage. I bought an Eastwood PC gun and need to learn the PC process.

 

Airpressure used is my biggest question.

Also would like to hear how you do a job from start to finish.

Only thing I am positive of is not to use the same oven you cook your food in....you'll need to either get one of those curing lamps or an old oven to bake the PC with.

 

I'm real interested to find out more info/tips myself, I've been thinking of picking up one of those Eastwood PC guns as well :cheers:

Stuff really needs to be clean of all oil and grease. Sandblast all old finishes off and wipe down with a good cleaner. Alcohol, MEK, or the such. and you need an oven that will reach at least 400 deg, a way to hang your parts with small wires. Then have fun I powdered my stuff last year but was able to use a walk in oven at work but I did use the eastwood stuff with no problems.

 

bitte schon

Maybe you should have bought a book before a PowderCoat gun.

It wouldn't suprise me if one of those Powder coating for dummies books is floating around somewhere. I just bring my stuff to work for some powder. Leave it in the morning and pick it up when I leave. :cheers:

cliktobuy thats some good info. thanks.

 

I bought an Eastwood gun and one of Eastwoods infrared heaters. I won em on Ebay about a year ago and never used em yet. The infrared light\heater is pretty expensive. I personally wouldnt have bought the infrared setup, but the guy sold the gun and heater together, so I got em both. The guy I bought the stuff from said he only used the infrared heater to do large items like motorcycle frames. Told me I'd need to buy a tempeture gun to monitor the temps when using the infrared heater. I prolly won't be using the infrared heater much, if at all. :shrugani:

 

Any more tips and tricks ????

I actually worked as a painter/powdercoater for a year. we mostly did high production stuff. The main problem with homebrew powdercoating is most people don't get the part hot enough for the powder to bake in. If you powdercoated something and it chips easily, than its not hot enough. If your doing parts that have thick metals it helps to pre-heat the part than spray it. Than when you bake it it'll stick better.

 

 

As for painting, its pretty easy. You'll be able to see if its too thick or too thin. IF its too thick you'll get an orange peel effect like regular paint. If its too thin than you'll be able to see through the powder. If your going to respray the part than turn down the voltage to 50 to 80%

 

 

The only pain in the ass part of powdercoating is when the spark arcs to the part or a contamination on the part causes the back corona effect (round circles where the powder is real thin and won't really stick). Make sure the part is clean and you'll avoid this problem.

 

 

Other than that, good luck :headbang:
