Shipping container - paint??

[dmcintosh]

So I posted a few weeks back and got some advice on how to run the electric in my shipping container project. Next question is paint? Looking for something that will brighten up the inside, and will hold up. We’ll be using this as a mobile Aquaponics demonstration so there will be humidity. Was considering maybe staring with https://www.amazon.com/dp/B001CRFYG0/?tag=atomicindus08-20 this to clean up the few spots with surface rust and make the finish hopefully last longer once applied. Any idea? Might also consider doing the floor, but as best I can tell it looks pretty well stain with some sort of oil.

I would seriously consider a Marine Grade paint like that used in bilges. It comes in colors, including White.

Do you a brand that you’d recommend?

I am not familiar with the various brands of paint sold in your area. Perhaps a local boat yard or shipbuilder could let you know what they use.

Alexseal makes some nice marine paint. So does Awlgrip. Alexseal is usually less expensive, but in no way inferior.

Ayuh,.... Rustoleum,..... industrial enamel,....

Any thoughts on the rust converter to treat the rusty spots? Yeah, nay, brands? Corroseal seems to get pretty solid reviews by most on Amazon.

I would leave it as-is or apply one of the zinc paints normally used to recoat tin roofs. I also wouldn’t expect much, connexes are moisture traps as it is so I’d expect to see major issues within a few years.

We will have ventilation, but agreed. My expectations are not that high. Just want it to look brighter and more uniform.

That's also true of every boat ever built, which is why they get painted.

Personally I'd use implement paint.

Powerwash & remove scale or peeling paint, wire wheel any bad rusty areas, than prime with a rust converter, topped with any marine grade direct to metal paint.

 

[K'ledgeBldr]

Just a good enamel paint will do.

It ain’t the paint! It’s the prep!!!

Thanks for the insights.

When I painted my 40' container, I used gloss white oil based barn paint from Tractor Supply. I just pressure washed the inside a few times over with a degreaser and then let it dry. Spray a few coats of gloss white through an airless sprayer and then epoxied the floor with some product from Home Depot (I should have used 2 gallons but I was cheap and only bought 1 so it wasn't as thick as I'd like it to be). Had it for a few years without a problem. The inside of my container was pretty rust free thankfully. Soon after painting I did add a small window on the closed end of it.

Before and after kinda...

Rustoleum 9100-series epoxy paint. Can also go over rust with very good results. Been using the stuff for 20 years and have no issues with it.

That’s the color scheme I am looking at too, white walls and grey floors, what did you use as a cleaning product, and did you run that through the pressure washer or just spray and then pressure wash?

That looks like. Good product. Was hoping for something water based, so the VOC would be lower, but this is likely more durable.

It will smell potent for a couple days, but the smell does go away rather quickly. I brushed the floor of my camaro with it over this past winter; the smell lasted maybe a week at best and it was gone. For inside a container, a small box fan might help speed the drying up.

Rustoleum might have a water-based epoxy, but I have never looked. The 9100 series hasn't let me down can be brushed, rolled or sprayed. When sprayed, I didn't thin it at all and used a HF "$18 disposable HVLP gun" with decent results. Don't bother trying to clean the spray gun as it will cost you more in thinner than the cost of the gun.
