Spray Paint Cans

Spray Paint Cans

(OP)
As I get older, I find I have less tolerance for cans of spray paint that don't. I have always religiously followed the instructions to shake the can for at least a minute after you hear the ball start to rattle and then invert the can to spray out the pick up tube when you are finished painting. I also used to clean out the nozzles with fine wire. I used to soak the nozzles in a jar of lacquer thinner. I used to stick the nozzles on a can of brake cleaner to blow them out. These days there are more nozzle sizes/configurations on the paint cans and cleaner cans that this method is no longer practical. One method I have found that works is to shoot the offending can with a .22. Then they spray real nice.

RE: Spray Paint Cans

I agree! After doing all the same having them spray perfectly for the first 1/4 of the next spray job they tend to utterly fail leaving you with a horrid failed spray job that turns calico as you frenetically work thru the other four cans of different colors with the same results.

RE: Spray Paint Cans

Exact same frustration here. Regrettably spray cans are still the cheapest way to get small quantities of coloured paint, so even resorting to using my own sprayer is only an option if I want to bleed all the propellant off the damned things after the nozzle plugs.

RE: Spray Paint Cans

Well, I normally destroy the nozzle when trying to get the cap off the first time anyway. And, yeah, there are so many configs finding one to replace it with is about impossible :)

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: Spray Paint Cans

The latest joy with these things, is the all position spray can. The major malfunction with these, is that you cannot invert the can to get the paint out of the nozzle before you put the can away.
B.E.

You are judged not by what you know, but by what you can do.

RE: Spray Paint Cans

I've been using the practice after clearing the tube/spray nozzle with the can held upside down, of storing the spray can upside down on the shelf... This keeps the feed tube out of the aging and thickening paint that normally settles in the bottom of the can when it sits on the shelf for a long time.. Of course a good shake is done before using the can after having been stored upside down.

Doing that, the experience has been very rare to have a can fail to spray... Very simple solution to prevent ,

RE: Spray Paint Cans

A friend of mine has a dart board above the work bench in his garage. A rather wildly thrown dart managed to penetrate a rattle can of black paint on the workbench making a nice abstract expressionist painting on the wall, bench and tools as it fell over and rolled around.

RE: Spray Paint Cans

We have similar incidents with cans of cold galvanizing spray in our plant from time to time- a tiny puncture of the can leads to some very interesting abstract artwork. Very irritating when it happens- they always tend to grafitti something that is very difficult to clean off!

RE: Spray Paint Cans

Way back a long time ago I worked in a composites facility. Applied parting compound to molds from a spray can. By watching the old hands, I learned to puncture the bottom of the can by slamming it onto a putty knife held on edge. No clogged nozzles to worry about, no tired index fingers either :)

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: Spray Paint Cans

Kind of a one-use only solution though, isn't it?

RE: Spray Paint Cans

Yeah, always used the whole can anyway. Parting compound is something you want too much of, not too little :)

RE: Spray Paint Cans

heh - some good stories there!
I've found that I can use my compressor to re-pressurize cans sometimes, as well as blowing the nozzles clean.
And sometimes it doesn't work- lots of times the smartest thing is to toss it and use a new one...
