disco_al Posted January 28, 2008 Share Posted January 28, 2008 Any ideas out there for removing powder coat? i have been given a bull bar for the disco, and as usual the powder coat has been damaged in places, so i want to strip it back, add a splash of zinc primer/undercoat, and repaint it with some nice hammerite type stuff (easier to repair scrapes than powder coat) cheers Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted January 28, 2008 Share Posted January 28, 2008 Get busy with the grinder (flap wheels) or have it blasted. ...or crack the powder coat with a hammer and leave it out in the rain. Al. Quote Link to comment Share on other sites More sharing options...
rtbarton Posted January 28, 2008 Share Posted January 28, 2008 Is it powder coat or plastic film? the latter cracks and peels, the former sticks like the proverbial to a blanket. Blasting may shift it, but you'll need some force, should be OK for a bullbar, not for panels though. Flap wheels may work, but I've had to resort to grinding wheels in tha past. A customer of mine soaks powder coated bits in a vat of stripper, but he won't tell me what it is! I've seen stuff advertised on the 'net, but it seems to be in the USA Removing Powder Coating Quote Link to comment Share on other sites More sharing options...

will_warne Posted January 28, 2008 Share Posted January 28, 2008 I had issues when I wanted to strip the powder coating off a set of rims. I found paining on nitromers to soften the coating made removing it with a wire wheel much easier. Quote Link to comment Share on other sites More sharing options...

Which type was it? - I think they do two, one is water soluble and the other is "original." Quote Link to comment Share on other sites More sharing options...
disco_al Posted January 28, 2008 Author Share Posted January 28, 2008 AFAIK it is powder coat. large chunks have become damaged, and let water underneth, leading to cracking. large chunks can be peeled off and snapped to remove them.

Guest diesel_jim Posted January 28, 2008 Share Posted January 28, 2008 When i had my old nudgebar re coated, the shotblaster machine would hardly touch it, the granules just bounced off. the shot blaster suggested i get a blowtorch (oxy was better) and just lightly "burn" the coating, not on fire, but just run over it with the flame until the surface changes from shiny to slightly dull and pitted. i took it back to the blasters, and it came straight off. no problem.

That sounds like plastic coating. Quote Link to comment Share on other sites More sharing options...
muddy Posted January 28, 2008 Share Posted January 28, 2008 Chuck it on a dyeing fire and it'll all soften and start to peel, should just be able to pull it off then. Quote Link to comment Share on other sites More sharing options...
OWL Posted January 28, 2008 Share Posted January 28, 2008 Find a shot blasting company who have an oven, they bake it overnight and then blast it ! http://www.beadshot.co.uk/Page3.htm Quote Link to comment Share on other sites More sharing options...

If this is a LR product it will be 99.999999999999999999999% plastic coated, LR do not powder coat apart from the 0.000000000000000000001% of the time Quote Link to comment Share on other sites More sharing options...

I found paining on nitromers to soften the coating made removing it with a wire wheel much easier. IIRC it was the original stuff. I wasn't having much luck with a wire wheel (it wasn't really taking off the coating) so I thought I'd have a go with an old tin that was lying around. I applied it liberally with a paint brush and left it for 20 - 30 minutes. Basically let it work in and soften the plastic (which goes white) and then have annother go with the wire wheel.
