Depends what is powdercoated.....either sandblast or chemical clean.
-
itsa frame . but it was recently powdercoater but i dont like the colour
-
Sandblast it, the powdercoater should be able to redo it.
-
im told that sand blasting wont get it off
-
Blast with Garnet will take a while but should take it off .
-
Sand blasting works but is slow as its hard to get off. I re did my cz frame that was powdercoated.
-
A good operater will get it off.
-
A friend of mine has a sand blasting and power coating business and told me the best way to get power coat off is to burn it off. Not with the oxy, but send it to a specialised power coat removal business to burn it off. As far as i know there is only one doing power coat burns for the whole of SE Qld.

You could always bump it , with a spanner and such.
Worked for me when assembling my newly painted frame. :o
I have just stripped the paint of a monoshock spring with paint stripper.
Have been told ,on this forum that it,s powder coat.
Sorta worked, sorta. ::)

I get a company called Colorex to remove powdercoating, new or old it does it easily & cheaply. It's a non caustic chemical bath. There may be a franchise near you.

is there a chance that this procedure will get in side the frame and cause damage from the inside out over a period of time
-
Nope, it water soluable and the guys give it a good was before handing them back. No different from washing the frame out with a pressure washer.

You can't powder coat over powder coat as you will lift cured powder when it is baked.
However there is hope, popular with custom Harley builders is to powder coat close to the color you want and then sand and over paint the powder coat in two pack. It is used to give very smooth finish on frames and covers up small chips.

My powder coater says you can re-coat new or newish powder coat without any drama's. He did a spring the wrong color and just coated over it. When I asked, he said there wouldn't be a problem, and there hasn't been so far. I use powder coat as a primer/filler all the time. It's way easier and cheaper if you cost your labor & materials when you sand blast, prime & sand a frame, Very labor intensive, very time consuming. Just scuff the powdercoat with some scotchbrite, a couple of nice coats of 2K and you're done.

Paul, I do powder coating.
Burning is the only real way to get it off but, You can sandblast but will take for ever and it is not cheap
If it is only new powder coat you can top coat straight over what is there.
When I do my own frames I undercoat with a zinc coat first that seals it (to stop rusting) and then top coat over it.
It can be recoated a number of times, only issue is if you get to thick it will cheap off easier.
When they do it it is best to bake the frame hot and then pull it out and recoat will still hot, there is no issue with the colours running together, I have coated yellow over black without any issue.
