I need to paint the inside of a barrel to store clean water (for dishes, showering etc). I hear epoxy paint is ideal for the job. Can epoxy paint be airbrushed? what should I consider when using it? Wouldn't that kind of paint clog the gun or something? Does it come out if I get stained?
Also I've never used a spray gun before and was thinking of renting one. My country is backwards so, if I couldn't find a store that rents me the stuff, How can I achieve a good finish without grooves and shit that promote algal growth?
If you clean the barrel you can just use it. Steel is harmless and coating would cost more than a used food grade plastic barrel.
It's a shitty plastic barrel, translucently white. I don't want to clean it every month so this is what I was planning.
Get one of the opaque blue plastic barrels.
^This. The white ones are often not UV-resistant. I've had blue barrels outdoors for over fifteen years with no deterioration.
Also this. The white barrels will get brittle and crack. Had a couple with used oil in them and the tops got holes in them letting water in and leaking oil out. Had to pump the oil over to a steel barrel and then burn the plastic barrels...
no blue plastic in romainia.

this one?

If its HDPE then don’t do anything on the inside but paint the outside. If you want no sun you’ll probably want no sun heat either so just wrap it in tin foil or whatever.
Now to answer the question, no there are almost no epoxies that can be sprayed on, once you get an aerosol grade mixture it will try almost instantly. There is sprayable PU, that won’t work on PE/PP but you still haven’t told us the actual material
>Steel is harmless
can leech out chromium, heavy metals etc
If the input source is chlorinated then there's some bleach thing you do to the whole damn thing to sterilize it and then it remains pure because of the constant inrush of new chlorine.
Coating the container won't make any difference on whether or not you have to do maintenance on it.

An opaque tank that doesn't let sunlight in will prohibit the growth of lots of junk.
Could paint the outside. What is the barrel made out of?
Agree. Cover the outside somehow. Build a wooden crate around it. You have to keep light out, and keep sunlight from rotting the plastic from the outside.
55gal barrels are a very small quantity of water. Consider building your crate large enough to hide 4 of them, minimum.
It can be as simple as a removable wall with two supporting sides that back up to the building. The barrels should be on a stand, and bulkhead fittings used so you can drain them easily.
Also look at the first flush diverter and the leaf and debris screen, the australians make. You can fab your own.
Yes, please post video of you running epoxy through an airbrush.
Painting sounds like a PITA. if you're worried about light leakage, why not just make sleeve for the barrel out of something opaque? Roll a big sheet of steel or aluminum into a tube, pop river the ends together, done.
Introducing Isocyanates into your drinking water...
FRICKING BRILLIANT
Dude, neurosurgeons put KRAZY GLUE when working on spines. I shit you not, they take a non-sterile brand-new tube and smear the shit on your vertebra. And nothing fricking happens in the end, guy walks out fine.
cyanoacrylate glue is not epoxy paint.
is wrong tho, epoxy paint does not contain isocyanate that's PU paint. but ISOC forms inert polyurea with water, epoxy is even worse its BPA with other toxic chemicals.
>t breathed isocyanate for 2 years working in paint industry
Get a black polyethylene liner.
A.k.a “drum liner”
It’s like a thick garbage bag.
I would not store water in a barrel and then use that water for cooking, or drinking or showering, if that barrel had any chemical coating on the inside.
Store the water in something natural and safe.
>Store the water in something natural and safe.
Natural as in... wooden barrels? A hole in the ground? Whale bladders? Seriously wtf is a natural water container?
The same way the cavemen did it
Alright. I went to the hardware store and they told me all the shit they had would flake off on plastic specially under water.
So what do I paint the outside with? What other ways should I have in mind to kill the algae?
Man, today I cleaned that shit and it felt like doing a prostate exam on an alien. All that green goop shit seemed to immediately generate negative pressure when in contact with any surface. Worst fricking housework i've ever done.
