    Default Powder coat removal

    What's the best way to remove powder coat paint so an item can be welded?

    I've tried all sorts of abrasives with varying degrees of success with most just softening the paint and smudging it around. Loading of the abrasives is also a serious problem.

    Thanks for your input.

    What's the base material that's been powdercoated? A steel wire wheel on my 4.5" DeWalt works really well, but will eat the S**t out of your base metal if it gets away from you. Sandblasting or beadblasting with glass beads is absolutely THE BEST way to get rid of powdercoating, but your part will have to be small enough to fit inside the cabinet.

    Default getting it off

    I know how to put it on easy enough, getting it off is a whole nother pain in the rear. Best ways I know are already mentioned in the above posts, but in some cases you maybe able to chip it on an edge and get a razor blade under it and peel it off. Dave

    True...I'd forgotten about that. I saw a kid trying it once and his hand slipped down the razor-handle and we ended up taking him to the E.R. so if you go this route be careful.

    the easiest way to remove powder coat is Klean-strip Aircraft remover, i use it all the time.

    Cool Powder coat

    For the matter of $60.00 You can get a spot shot sand blaster Very good and small for what you are trying to do.And well worth the money.I don't know if there is an acklands grainger near you but that's one place to buy it.But I don't know your location.

    Default Thanks

    Guys - Thanks for the input. My problem is I need to box a steel trailer frame that has been powder coated. This will require removal of approx. 42 linear feet of coating along the edges of the channel.

    I've used flap disks in the past but that gets very expensive as they load too fast. Also used the wire brush with better results. I have a small sand blaster but having used it on previous attempts at removing powder coat, I wasn't very satisfied as it took a long time and used a lot of media.

    Thanks Rotary - I think I'll get a can of the aircraft remover and give it a shot. Sure will be easier to attack this with a chip brush than the other ways.

    Default Aircraft stripper

    The only reason I did not mention this method is because I have had problems when it came time to recoat the item. Seems the stripper gets into the pores (especially on aluminum) and even after a good cleaning it still leaves a residue in the pores and outgases when being baked, the only way to get rid of it is to prebake the item and reclean the item before recoating and that gets gets time consuming and is not very cost effective. Keep in mind also that if you just need to do a spot repair you only have to clean around the effected areas and powder can be applied over the old powder with good results, the entire item may not need to be stripped. .
