Spraying POR-15 paint.

Steve-Maine · Oct 17, 2020

I'm getting ready to sandblast my dump trailer. I'm going to use POR-15 and then 2 coats of Rusteluim top coat. Can I use a cheap HF spray gun and clean it out afterwards with their solvent. I have always use POR with a paint brush but spraying would be easier.. Any input would be helpful. Thanks

Can you get it thin enough? And would you want to?
I suspect spraying it on would result in a layer to thin to retain the properties desired.

What does their website say?

Paint cans themselves usually have recommendations for spraying and brushing.

Here's their recommendations.

Says it can be sprayed, can be thinned with their solvent, cleaned with lacquer thinner.

Must be some bad stuff to breathe!

I have a HF pressure pot sprayer, works well for what I do. It would probably spray it without thinning.

The cheap HF HVLP gravity fed guns do a decent job even with fairly thick paint. Might leave a little texture in the paint, but shouldnt bother on a trailer.

If you can do the whole thing at once, you can afford to toss the gun when you are done.

At one time there was some paint that was for dump boxes, in that it was slippery so the box dumped easier.

Use the POR 15 metal prep to kill the rust that is down in the pits. even sandblasting won't get it all out.

I have had grief with it on bare not rust metal. Sand blasting might give the meatal enough tooth to hold it, but mush of mine just flaked off new sheet metal. Where there was rus near it, it was fine. Jim

Yes Jim, I use rust converter all the time. I follow the instructions and work it around for 15 min.to get it to work in, then after 10 minutes of sitting I aggressively wash excess off. That eliminates the problem that you have.

I would use an outside air source That stuff dries hard as a rock.

i would not spray it. the overspray will get all over everything and it is dang near impossible to remove. i have a down draft spray booth at my shop, and i would not even shoot it in there. use a foam roller.

I use Eastwoods acid etch primer on bare metal. wipe it down wiht acetone before priming.
