Re: Powder Coating Removal


Rather I just did a small salt spreader frame that is about three by three and the darn thing took me 200 lbs of medium glass at 110 psi. You could get lucky but often it's quite the hastle.

Re: Powder Coating Removal


Was blasting some harley rims yesterday that were powdercoated. At first I wasnt getting anywhere.... adjusted pressure, dialed down the media and success.... Powdercoating if thin and brittle comes off easy. If its thick and gummy watch out, you could be screwed. Best advice I got for you is take a knife or something to scrape the coating with.

Re: Powder Coating Removal


thanks guys, going to have a look at it friday. i see by the pictures he sent its peeling off. approx 1/3 of the sides are allready gone. I will call the trailer builder tomorrow and ask them what they used for paint it doesnt look like powdercoating to me.

i will take my knife and see how it comes off when i go on friday.

thanks again for the tips!!

Re: Powder Coating Removal


The pictures look like this project is gonna be an easy one. Actually, the only thing thats gonna slow you down is blasting the rust out in places. Have fun.

Re: Powder Coating Removal


i was wondering if anyone has ever tried using a chemical stripper on powder coat before blasting? like an aviation stripper? and how well it works

Re: Powder Coating Removal


Powder coat sucks.

The best media I have found is steel grit it works a treat.

Re: Powder Coating Removal


Looks like the finnish is a baked on enamel, comes off ok
Have a trailer dealer here in Maine that makes trailers and they spray them the with High Soild Enamel, then bake it on so the finnish is a hard looking, shinny like the pitures you posted.

Try a fine glass first, it will clean it to a whiter finnish faster than the med.

the blasting will go just a bit slower but in the end you get a better, cleaner finnish.

I've been using the fine on dumptruck bodys, use maybe a bag or two more but get a cleaner looking finnish in the end. and the customer loves it.

My two cents

Re: Powder Coating Removal


Powder coating is best stripped first with a aviation stripper to soften and razor scraped to remove mils of thickness...then blasted...I have done a bunch and found that is the best way for a mess-up by the coaters or a fresh job...old powder is still tough to get off. I would guess that trailer is painted with a DTM acrylic to cut time and expenses for the builder...just a guess..

Re: Powder Coating Removal


This thread is from back in March of this year. Hope he is done blasting it now.

I can't see that trailer being powder coated. Maybe a force dried enamel. A fabricator powder coating something that size would be more than it cost to build the trailer. Ain't no trailer builder going to do that.
