Advice on repainting a powdercoated enclosure
« on: May 05, 2014, 03:46:38 PM »
Hi there,

So im looking for some advice on how to paint a pre-powdercoated enclosure.  I have a TEB setup that i just finished cutting the holes in, and in doing so caused some damage.  There are a few decent scratches and scrapes on it so id like to give it a new coat of paint.  IF anyone has any advice id love to hear it, id rather not paint this thing incorrectly and then have the paint peeling off once i get everything installed.

Points of consideration.

Do i need to wash it? i had to use a good amount of cutting oil at times, and im sure there is a residue?

Paint prep?  Do i need to sand it down, fill int he scratches or will a decent paint fill them in?

Primer?  Do i need to prime it if its been powder coated?

Is it even possible for paint to adhere to powder coats?

I was thinking of a good automotive spray would be the way to go.  Other opinions are welcome.

Cheers,
Jeff

I haven't tried it myself but this article seems to be a reasonable process.

After reading that article it makes me wonder if its worth it.  OF course the most noticable damage is on the door of the enclosure, which will be most seen. FML

I work with electrical enclosures that are powder coated for a living.... they often get scuffed during installation and need a little "touch up paint".

You can probably get these colors ^^^  from Newark or local industrial electrical supplier.

I always get to farm the actual touch up part out... but cleaning off the oil on the surface followed by a mild scuffing on with sand paper is all I ask get done and I have had no issues.
