HOW TO: Get Paint out of Aerosol Spray Cans!


Hi folks – this is just a quick video to
show you how to get paint out of an aerosol can. Now why would you want to do that? Well, sometimes in some of the bigger cans, when you think it’s finished, there’s still some paint left in there, and if you’ve
got a small project you may want to use that or, in my case I saw some colours that I
really liked in the local £1 shop really inexpensive, and I wanted to use
them on a project, but I knew the spray pattern was going to be too heavy
and too rough, I wanted finer control. So, I took the paint out of the cans and I now have it in these bottles and I can use that in my air brush. Now the first step
is you need to release the pressurized gas that’s inside the can, that acts as a
propellant for the paint. Now you could just invert the can, hold the nozzle
down and spray that gas out, that should leave most of the paint behind – however it’s very time consuming. So what I prefer to do is I pierce a small hole, near the top
of the can, and let the gas vent out. Now obviously you want to be doing that in a ventilated area, preferably outside and you want to leave the can venting
for a good length of time. I leave mine overnight outside and that
works fine… after all the propellant gas has been released or, as I say preferably overnight, you want to cut the top off the can – you need to be a bit careful here because you’re cutting into thin steel and there can be sharp edges, I
use tin snips, stout scissors will work just as good – I wouldn’t however use a knife because it could slip and you’re just
asking for injury. once the top of the can is cut off, the next step is to get the paint out of there and into your bottle now, I got these bottles out of Bodycare,
but you can get them out of any main supermarket, they’re meant for carrying
shampoo etc when you’re traveling. So, just trim up the edges of the can, and
bend it slightly to create a pouring spout. And pour it into the bottle. I’ve
also made sure that the two agitating balls have went into the bottle too
because the paint well settle out in the bottle over time, and that will allow you
to give it a little mix just before you use it. Now if you don’t let the can vent
for long enough, there could still be a lot of propellant gas, even in liquid
form – and this is what can happen if you don’t leave that for long enough – it
can basically boil up and bubble up the paint and cause a spillage. So, think of it like
when you shake a bottle of coke and you open that lid – and what happens – it all
fizzes up – and that’s a similar thing to what’s happening with the paint, there’s
propellant still dissolved in that paint if you don’t let it vent for long
enough and as soon as you release the pressure it allows it to turn to gas and it
all bubbles up. Now, a quick note on health and safety, because there are those out there who’ll say that this isn’t the most safe thing to do… well I didn’t use gloves
or masks or anything like that and you probably should – eye protection especially because the paint could splash – but I’m still here to tell the tale, I’ve been doing this kind of thing for years and that’s just how I personally go about it – but I would have to recommend that you do use those safety things and take precautions. So, I hope that has been useful to some of you and if it has, I would really
appreciate that if you would hit that like button – maybe even subscribe to the channel, I’ve got a lot of different projects coming up. But for now, thanks for watching and I’ll catch you in the next one!
