Will "rattle-can" spray paint lose their "fizz"?

Post by Rhhick » Mon, 01 Apr 2002 04:29:09



Sometimes when I'm the suburban shopping meccas, I'll stock up on Krylon
(sometimes 30% extra!!) at Wal-Mart, etc. & now I'm wondering if they sit
around too long before I use em, can they go bad, ie. lose their pressure?

Dunno a scientific answer but I've had partially used Krylon for almost 3
years without any problem.  I had a can of Rustoleum for much much longer
(used to touch up my son's basketball goal).  Could be pushing 10 years but
I can't remember.  Seemed to be fine last time I used it.  If these used
cans are OK I'd suspect the unused would last longer.

Yes, sometimes they do.

Biggest problem I've had with old paint is to get it to shake well and then
mix properly. One thing that helps is to soak can in warm water for several
hours to loosen it up, and then it seems to shake much better.

I just used some Rustoleum paint that is 6 or 7 years old. Didn't want to
shake up, but the warm water soak helped.

    In the very few instances where I have had them go "low fizz' I have put
the cans in a  pan of warm water  (about 120 degrees) and let the sit 15 or
so minutes.   Then shake the heck out of them.   They warm up quick and
spray well.

    DO NOT PUT THEM IN A  PAN OF WATER ON THE STOVE.   WARM THE WATER, TEST
IT AS YOU WOULD A  BATH FOR A  BABY, AND PUT THE CAN IN THE PAN ON THE
WORKBENCH.

   Most definitely; however, it seems to take a while, years rather than
months. (Mos' annoying, as I had a few cans of discontinued colours that
are now pretty much useless. :P )

Tir',

DON'T do that.  It's quite dangerous.  Besides the danger of the can rupturing
about the pierce, there's a fire danger as well.  'Tain't worth losing an eye
over a buck's worth of paint.

1. Epoxy the bottom of the can down to a concrete block. Use a .22 at
some distance to poke a hole near the top.

2. Set up a jig that has a power drill with a 1/16" bit being pressed
down upon the top of the can by gravity. This can be as simple as a dril
press with a weight tied to the lever. Turn on, walk away.

3. Wrap can with det cord.

If the pressure is really gone this will not be a problem.  IF HOWEVER
there is still pressure in the can the contents will be forcibly ejected
with no directional control.  We pierce empty aerosol cans at work all the
time.  We have never had a can rupture.  We use a recovery system and some
guys just smack the can on the edge of a steel work bench.
To recover paint I would suggest some way of enclosing the can and allowing
an awl to be inserted into the top of the can without allowing the contents
to spray all over.  You could then pour the paint out the hole you have
made.
Above all safety first.  Some aerosol propellants are flammable so no
smoking or open flames.  Cover can.
