Hi all, what's the best and most effective way to remove powdercoat from a frame?
-
Im adding a comment, to keep up with he tread, as i want to know the answer:)
I was going to have mine sand blasted, but im interested in knowing who agrees, or disagrees
-
I would have thought sand blasting would be the most practical, least time consuming method of stripping powder coat. Or just wait a while :D It often doesn't take all that long to come off on its own!!
-
Aerosol gasket stripper works better than anything else I have seen.
Blasting powder coat is awful - it's soft enough that the blasting media just bounces off. A very slow, tedious process.
-
Having had to remove powder coating in the past by blasting convinced me to avoid powder coating frames ever again. It's a pain in the arse, in fact my blaster guy told me never to bring him a powder coated frame again. Someone once told me there's an acid treatment that works a treat but I don't know the details.
-
Lead battery acid , most brake fluids, shotgun blasts, plastic explosives, leaving laying on ground outside for ten years or more
,or as Nathan has said, proprietary aerosol gasket remover is a pretty good way go.*
* In well vented area away from other painted items.... oops been there done that stupid mistake to a nearby painted surface...

I have used 'Nitromors' paint stripper on small powder coated parts with good results. I guess a complete frame would need a good thick coat applying and agitated every now and again. A pressure washer, dry, and then repeat. I hate blasting as it removes the frame number and makes the frame a bit thinner !

We sell a product to powdercoaters called Methylene Chloride that they use to strip existing coatings.

as with all things in life there is a tool for every job.
Read the thread about vapour blasting. I mentioned a stripper I use. Made to remove paint and powder cost. Good grief it is the business! (Scary almost, HS&E and all the way and no short cuts)
Sanding, and blasting will just make a sticky mess. It will take ages, look rubbish and then applying a new finish on top will be yuk.
Find a professional stripper and pay to get the job done properly. It is money well spent and you can get on with your life!

I use a Colorex franchisee to remove powder coat. Cheap & the best way to do it, even the local powder coaters take stuff there to be done. Blasting is a PIA. There may be a Colorex shop near you.

Read through all the HS&E stuff that came with the tub l've got.
'Dichloromethane, methanol.'
Bloody good stuff, if you can get hold of it. If you have a pro stripper who uses it it, then it is worth every penny to get them to remove dthe powder coat from the frame. Amazing stuff to be terated with respect, (from behind the safety of thick chemically resistant gloves, all flesh covered and a full face visor!)
