For the last (hopefully) time, how to decant spray paint.

[chicken45]

Yes! Thank you!!!!

There are several methods of decanting spray can.  This one is interesting.  I still use the nozzle with a tube method.

I would not attempt your method.  I'm actually surprised that the paint (with the propellant still dissolved in it) didn't "boil" over and start coming out of the hole you punctured in the can.  Also keep in mind that the propellant is a highly flammable gas which is released all at once.  I would not recommend doing this indoors, especially if it is a basement with sources of ignitions like a pilot flame on a water heater, or other sources of sparks.   I'm probably overly cautious, but I don't think that is a bad thing.  I recommend doing this outdoors.

I absolutely agree that it is very important to lat the pain de-gas.  It seems that the propellant (probably liquefied propane) is mixed with the liquid paint and it takes a while for it to evacuate from the paint.

I wouldn't worry. He lives life surrounded with gas. He de-gasses indoors, or in a car, after White Castle onions all the time. He lives in constant danger to serve as a warning to others. Thank you, John.

Gaaa!  My mistake.  It's calle "Oxide Red", not "Zinc Oxide".  But I still think it has that orangy red rust color that Pennsy fans have come to know and love from the old Floquil Zinc Oxide (believe me, I know that color well... I've touched up and "improved" a few engines for folks, brass and otherwise, with that paint!)

Sweet! Yes! Thanks, Max!! We sure do love that orangeyness.

Man, you catch the smallest misteaks.

if it matters, i've only tried krylon, the regular spray bombs ...
they're supposed to have a non flammable propellant, small sealed room with a cigarette going, lol

Where do you buy the Krylon spray paint?  I was at Home Depot this weekend and all they carry is Rustoleum sprays (those use highly flammable propellant).

@Lemosteam
John, the jars you use for storing decanted paint are made for food-products. When exposed to the organic solvents in the paint the rubber seal on the lid might swell or harden over time.  I have had that happen to me in similar situations. This is just a heads-up if you are planning on long-term storage of paint.

Krylon ... at your local WalMart store, lol

Ok, thanks. I just happened to be at Home Depot, so that is why I looked in their spray painit section.. Next time I go to Wally-mart, I'll take a look at the paint section.

I looked over my collection of spray paints I found some Krylon paints.

1. Krylon Fusion for plastic (works on wood, metal, ceramic and more).  Bought it back in 2007.
Warning mentions that the can contents is extremely flammable and it has hydrocarbon propellant.  Hydrocarbons are flammable.

2. Krylon ColorMaster PAINT+PRIMER with durable CoverMax technology.  For wood, plastic,metal. Bought it about a year ago.
Warning mentions that the can contents is highly flammable.  Among other things it contains Propane and Butane (which while not specifically defined are most likely the propellants and are both Hydrocarbons). Hydrocarbons are flammable.

What Krylon spray can paint you have/had which contains non-flammable propellant?

[wvgca]

the non flammable propellant is the part I remember best, but I -think- it was the Fusion labelled one ??
I do remember it was labelled as being safe for plastics  ...
This was probably spray bombs that I bought in 2010 - 2012 or so, I've been done that part of it for five / six years now...
Unfortunately I got rid of the bombs just after that, and just kept the paint in an old Gatorade bottle, which I still have downstairs ..
The left over paint itself is not flammable with a BIC lighter ??

If it matters, I airbrush sprayed Atlas code 100 HO n/s track and turnouts

"Safe for plastic" doesn't automatically make it non-flammable.  Are you saying that you still have some of that decanted liquid paint and it is not flammable? Maybe there was another version of the Fusion spray?  Unless someone here still has a can of that paint we'll never know (since my highly flammable Fusion spray paint is from 2007).  I believe that the Fusion line was discontinued and replaced by the "ColorMaster" line, because when I bought that ColorMaster paint I could not find any Fusion paint anywhere (I wanted it because I've used it in the past and it was plastic-safe).

Next time I'm at Walmart I'll look at the currently available Krylon spray paints.

Ace Hardware, at least my local store, has Kyrlon Fusion.

Thanks Mike - I'll check there.

yes, i have maybe a quarter bottle [gatorade] of probably five or six year old decanted liquid paint , well seperated..
and no, it's not lightable with a bic lighter, just the paint, no propellant at all..
and no, i don't have the bombs themselves, but i -think- it was fusion ??

Bringing a not too old thread back to life. 

Question, will the OP's method work to decant non-paint aerosol?

Here's my situation.  I found two giant (19 oz. each) cans of new or near new disinfectant.  Similar content as Lysol but Walmart brand.  Unfortunately they are clogged.  Not the spray nozzle but the actual "stem" coming out of the can.  I'm guessing the chloride content may have damaged the parts in the valve stem.  I tried mechanical methods to free it up along with soaking it in denatured alcohol to no avail.

Since we are in a pandemic, I just didn't want to throw them in the trash and was thinking about decanting them and putting the content into an empty mechanical spray bottle.

Since it's not paint, even if there was some splatter, no harm done.

And if this is possible, do I need to degas the liquid?
