Pro Tip: Decanting Spray Paint
Вставка
- Опубліковано 16 тра 2024
- If you've got an airbrush and a bunch of spray paint taking up room in your shop, then you might want to consider decanting those paints into smaller bottles.
I didn't know if the bottles I used would react with the paint solvents but after a few weeks, it doesn't look like that'll be a problem.
Definitely make sure that the paint WARMS UP and has been stirred before capping it. My green paint turned into a lime volcano after it reached room temp and I tried to stir it.

Note: Spray paint cans are measured in ounces by WEIGHT. That's 11oz by weight, not volume. You will not get 11oz of paint volume from that can. More like 8-10.
Thank you for that info!
NP! I started doing this a couple weeks ago and noted how I wasn't getting what I thought I would from the cans. That's when I saw the WT at the end of the OZ measure, denoting that it was by weight, not volume. I also noticed that metallics net less paint per can, I believe this is due to the metal flake in the paint making it weigh more, hence less volume per ounce.
I don't have air brush... after decanting, can I just use the paint with normal brush?
Yes. 😊
Very informative yet simple and concise , You're a hero bro. Thanks
Excellent! Thank you for this!
I'm glad I found this video... I ordered an airbrush for painting my 3D printed models and this will make it so much easier to work with.
wow, very thoroughly done, thank you
Thanks for the tips on decanting, mate. Nice video. Happy airbrushing! :-)
I love that "Warning: Science Ahead" quick pop up picture. 🖖
I decided to do this to about 40 spray cans, some full of paint but no pressure etc. various sizes from the hardware store 12oz down to Testors 3 oz. I did the puncture and cut method but what I did was invert the cans so they are sitting on their lids. Then with a rag over your hand and the can, puncture the very bottom of the can (I used an old wood spade bit, carefully twist n push until you get the little hole. Don't disrupt the can or the paint may decide to spritz out) You can put it in the warm bath to de-gas and walk away then when ready I used a old can opener and depending on the design of your spray can you can cut off the entire bottom or use the can punch and poke a few holes one side and a breather hole on the other then pour you paint into your jar. You might need some tin snips to cut the hold bigger if you want the marble out. None of my cans were thin enough to cut with a utility blade so this way avoided having to jostle the can while sawing into the side. (And yes...do not use plastic cups - I found out the hard way - I was doing 2 cans and I put the first into a plastic cup so I could see how much I had and within 5 minutes there was a little ring of paint around the bottom. I only thought the cup had a crack so I picked it up to put in into another cup and that's when I realized the bottom was completely melted. So the entire cup just emptied out on the floor. That won't happen again!)
Ever see a comment that makes you feel kinda dumb? Like it was right in front of me, why didnt I do that? I have several cans that have no pressure but still full. Just couldn't make myself theow a full can away. Gonna go do some airbrush primer right now. Hear the $5 can has 20x as much as a $15 bottle from store of same stuff.
Hasta ahora este E el mejor método para abrir y vaciar un aerosol. Muy bueno el canal. Gracias por el tip. Saludos
I appreciate your humor :) Thanks for the video!
Method 1 is so awesome
Thanks for the tip
Worked like a charm for me…although i diddnt have warm water so i just boiled the paint with a heat gun in the can…after it settled there were no bubbles. Poured it into a quart size paint can
I repeated the first method successfully. I'm just using the paint on my airbrush.
Thanks a lot for this tip.
It's way cheaper than buying other inks and save a lot of space if compared to polyester (automotive) cans (a quarter gal).
In my case I use an automotive thinner (for PU and polyester inks) successfully.
Also, spray paint cans are much more widely available. It's very easy to find them in various colors across different hardware stores and automotive stores, as opposed to buying airbrush-specific paint in the color you want.
Can you use the paint decanted with a brush?
Can u paint with this with a brush?
Yep
Hey man,thxs.Simple and effective hack.Will save me a couple of euros👍👍
I've been using the first method. It has been working best for me to stir it before dumping it out of the can. That releases the trapped propellent before transferring to the storage container.
Good idea with the warm water bath. I haven't been using one of those.
I've been using a metal snip to cut them open. I was surprised to see your razor worked as well as it did.
Ohhh stirring before dumping! That's really smart 😅
I like the way you put a paint sample on the lid of a clear bottle :) You can turn the can upside down and exhaust the propellant before cutting open, but why not just spray out the amount you need onto the wall of a jar and leave the rest in the can, people have been doing that for years ,( without a straw). Lastly it's a bad idea to use lacquer thinner, in enamel paint you want enamel reducer.
I think it's for when the bottles are stored next to each other in a drawer/box, and you're looking down at them from above. It can be hard to see the side of the jar that way.
@@DeeeFoo exactly what I was gonna say..
Cool , second guy i seen puncture the can , im doing this method ty
*Thanks man =) 1st method obviously better, good luck trying to find a respirator right now.*
6:45 if you run out of gas in the can - use a tire Valve Stem - take the cap off of the can - and don't over do it when you use a air hose tire inflator attatchment. the best way though would to be to tip the can upside down if its a can that says you shouldnt spray it upside down (the ones with a tube going to the bottom - spray until all the gas is gone - then puncture after you turn it the right way up - and let the paint settle off the top and sides
hello, nice milestones!! I saw your video explaining how to take off the spray paint ok tell me please! Can this spray paint swirl guitars in water? if yes which spray should i use? thank you so much
I don't know about guitars, but I've seen people use the spray paint on the surface of water to make swirl designs so... maybe? I don't think they use any special kind.
After opening, ( punch a hole on opposite sides to get propellant out quicker) leave the can in a bowl of hot water for a few minutes or use a heat gun. Then stir with a paint stick or Popsicle stick to be sure you get out all the propellant.
If you consider the amount of paint and air, it seems like turning the can upside down could spray out all of the air, but it must not work in practice because nobody does it that way.
Does your decanted paints fizz up badly in plastick bottles beacause im having a problem with my bottles to gas up and almost spray everywhere while opening
Yeah you need to let it sit uncapped for an hour or so with a little stirring because there's still propellant dissolved in the paint. And I wouldn't fill them up to the brim of the bottle.
has anyone used the rust-oleum protective enamel brush paint in the one pint cans in an airbrush
If you don't shake the can before making the hole, isn't the paint you pour into the jar not mixed properly? Won't you have to scrape some sediment off the bottom of the spray can?
I'm interested in doing this because I can't find Rustoleum Dark Machine Grey in quart or gallon cans, but I want to use my HVLP gun. Thanks!
I want to do the same thing……did you do it? How did it work out? I want to use the paint,but,want to spray with my hvlp gun, I’m sure I’ll have to thin it out, but, what about adding some hardner to the paint? How many can to get a gallon of paint?
Why didn't you tape over the hole and shake it up before cutting and pouring so you get a well mixed paint?
More paint from straw method .?
I have question, you said that even using direct spray it's still bubble in the paint. But if you paint something normally from that spray paint why we never concern about the bubble? thanks
The solvent evaporates very quickly when sprayed in a thin coat. When collected in a bottle, it does not have the chance to evaporate as fast.
@@PressXProps I see. Thanks. 👍
Would it help if you put the bottle in a warm bath while stiring it? Keeping it warm. To get the bubbles up
I’m pretty sure it would, yes. Good thinking.
I'm new to this hobby air brushing that is 👀 if I use the paint from a spray paint can what method should I use to clean the airbrush? I got one but I'm afraid I'll mess something up by clogging it
The can should tell you what the best solvent for cleaning that particular paint is. I use some cotton swabs and paper towels soaked in it. But try not to let the solvent sit in the gun or it can erode the o-rings, so leave it disassembled overnight so the solvent can evaporate. Good luck!
Use mineral spirits in a ventilated space. Do not use acetone because there is a rubber seal in most airbrushes that will shrivel if acetone touches it. Sometimes, in rare circumstances, you can spray acetone quickly to remove tough clog, but I've damaged a seal before with acetone and had to wait for it in the mail. Mineral spirits are fine. Clean the airbrush before the paint dries, but if it does dry, take the parts off and soak them.

Can't you just turn the can upside down to release the has? Then cut off the top if can
Hi, how long can I store a lets say Montana paint? Can they store longer with airbrush medium Mixed?
Ooh, I'm not really sure. Montanas are really nice. AFIK, the paint itself should be stable for a long time. Cans tend to go bad because the tube clogs or the propellant slowly leaks out. So if you have a good, tightly sealed container, they should last for decades.
Before puncturing you could spray upside down to remove some (or all) of the propellant
You could. Then you'd have to keep you finger on it for ten minutes and occasionally warm the can up back up. Or poke a hole, leave it in the warm water, and walk away.
Press X Props your lazy idea, me likey
@@PressXProps
use tape instead of finger, problem solved.
@@PressXProps Another youtuber used a long clamp and a vise. He tightened the clamp just enough for the propellant to come out.
How come the pressurized can doesn't explode when you puncture it? Is there any risk of explosion if you accidentally cut too big of a hole? Also, I can get a can of spray paint for $1 and I am wondering if this is a way of getting (new) cheap paint the cheapest way.
((I know you can go to some places to get free "unwanted" paint, but the color white is the most popular, so the least likely to find, while white spray paint is one of the most common colors (black being the other most common).))
The walls are thick enough to keep the can from completely rupturing or fragmenting. I've shot cans with guns and although they look like they explode, it's nothing more than rapid decompression. You'd need to poke a pretty big hole instantly to get that (like bigger than about 9mm).
If you can get it that cheap, this could certainly be a good source of paint.
Cool thanks. Sorry for the late reply. I just changed my youtube setting because I wasn't being notified of replies.
Shipwreck Diving too late, he did it, now he’s gone, all your fault, sleep tight - if you can
I fount cheep $2.50 cans exports don't mix with other good brand s crows feet .must be the water in them acrylic spray paint shiny finish tho.
“But is not necessary.. it is a little necessary” 🤣🤣🤣 u funny!
Use glass jars instead of plastic ones. I pour my paint on plastic ones and about an hour later the chems in the paint melted the plastic. Imagine the mess I ended up cleaning!!! Not sure why I switch to plastic jars when I had done it with glass before. I totally messed up!!!!
Yikes! Yeah test them first for sure. The ones I used are still holding up just fine.
Lol, I used a glass jar buuut....used a plastic fork as my mixer. BIG mistake, my primer now has plastic melted into it haha
Just wondering, how do you clean spray paint from a airbrush because I was told it’s hard?
I've had good success with lacquer thinner but I'm told mineral spirits is better. Any solvent that works on spray paint should be fine. Just be careful of o-rings and plastic parts.
Other UA-camr videos I've seen use Acetone for airbrush clean-up, soap & water, final spray with 90% alcohol.
EDIT: I tried this out with dupli-color automotive latex paint and it worked perfectly! I used method 2 and followed the instructions and had no issues. I expected it to work anyway, but this is for anyone else wondering. This should work with any rattle can paints as it worked with sticky latex paint.
Would this work with vinyl automotive spray paint like dupli-color? I need to mix colours for a project and can’t find another way to do it :(
(I’m thinking method 2)
I don't see why it wouldn't work. Give it a shot and let me know! I'll pin your results in the comments.
@@PressXProps Thanks! I'm gonna try it soon. My dad has worked with these vinyl sprays a lot and he said it should work fine too. I'll try to remember to post another comment when I try it out! (:
Press X Props I just tried it out and it worked perfectly! I’ll edit this comment mentioning that and you can pin for others if you want (:
Got my air brush. An spray paint all same type. Sume different brands do mix together. But cheep export paint don't mix with good brand .
@@khl0rine Did you spray it using a paint gun? Did you have to reduce it or anything?
Either paint cans arent near what I thought they were, or that utility knife is a beast!! I figured they were fairly thick not like a po can.
The walls feel thick because of the positive pressure inside, but they are a little thicker than a pop can.
Wouldnt inverting the can, then venting off the air be the easiest? Its what you do to clean the nozzle anyways. then you can puncture, and drain.
It seems like it would work to turn the can upside down to get rid of the air, but has it actually be done? Nobody on UA-cam does it that way.
Yes that does work. However, it causes the paint and can to get extremely cold which causes the paint to hold more dissolved gas. No shake for 12 hrs and top puncture works the best because the gas is released without passing through the paint like it does through the straw with your proposal. Also, this takes some extra time, in which I mean 5x more than puncture method.
I have silver spray paint but I only need like it in one spot on a project can I just shake it then spray it in like a cup then use a brush and paint it on?😂🤨
Yeah I've done that. It'll be pretty thin and might take a few coats. Great for weathering.
What if u turn the can upside down to release the gas then open the can up.
Basically the same as the first technique but you won't be able to walk away while it drains. And the can gets crazy cold. But yeah that's another way to do it.
Tip for if you're keeping the spray cans that have the tube going to the bottom - prevent the tube from clogging after use - hold can upside down - spray until there is no paint coming out. - revert to my other comment if your can runs out of propellant (use a tire valve stem and air chuck to add air into the can with the cap off - do not add A LOT of air!)
Wow..I thought puncturing paint cans explode! Neat!
Allie Hunter I’ve seen a video of a guy cutting(using a jig and safe distance) a gas tank from a blow torch with an angle grinder, it was full of gas, nada, you can technically do it with normal protection equipment... tho I don’t recommend it.
First of all, you want the paint mixed, otherwise you do not get all the color inside. I just got some tin snips, inverted the can, put a rag over the bottom, cut the bottom edge with the snips. The gas will leak out. Cut a bigger hole, a couple more snips, and pour into a bottle. Done.
i put my paint in a glass coffee jar MACONA with the press fit lid and when i later went to the shed the lid was 10ft from the jar, now i know
Lol, im not sure what that was, 3:31 Boarderlands?
Yup. Just killin' time... and loaders.
Bruh use a freaking WD40 nozzle that has the lil straw SMFH 😂
Where do you dispose of the cans after you decant them?
I just toss them in the trash. They aren't pressurized anymore or anything so they shouldn't need to be handled specially.
Thanks
Let the paint dry in the can, before throwing it in the trash.
Man has a respirator, mitre saw, various other assorted power and hand tools, knows the ideal gas law, and got specific bottles for this, BUT HAS NO FUNNEL?!
This is an excellent point.
I didn't see any ware in the comments . SHAKE THE PAINT UP FIRST. DON'T WANT ALL THE SOLUIDS IN THE BOTTOM OF THE CAN.
Less waste 🤗
Why need the second method when the spray paint can is still functioning.
Because he's trying to use the paint in an airbrush.
Just spray it into holder and let it stand for a while
Mark the top so u know what’s in there?!? The jar is clear!
And then I put them in a box where the lids are all that are visible.
Fluorescent paint is not color fast - the paint will fade and the color will go away under uv (if outside - the sun) the fluorescent color will break down. Just so people know :)
I am about to do this to fluorescent paint so thanks so much.
@@cclaudio8069 for sure! I still use fluorescent paint! A way to help it last longer is a good clearcoat or 2 part clearcoat that specifically says it has UV protection and a decent wax after paint has cured. And nothing wrong with re-painting in the future to something fresh and different!
@@cclaudio8069 If you save any of the fluorescent paint, put the paint inside of a solid container - sized to what you are getting out of the can! Old pill bottles work nice! That way it slows down the breakdown process!
👍👍👍🇺🇲

"Don't submerge the hole..." Like you did?
I deliberately did not submerge the hole
"So now looking down at the top of the jar, I'll be able to see whats in there."
Yeah, cos its only CLEAR plastic and it might be hard to tell otherwise.
And when the pigment separates from the solvent? And if they're all in a box or drawer with other colors that are similar? Or if someone uses a container that's not clear? Other than that, yeah sick burn, dude.
You know, there's no reason to cut open a can. In fact, you don't have to puncture the can at all nor do you have to use a straw and it takes less than 5 minutes.
I don't think any talking necessary just do it 🤷
Why are we labeling the cap of the jar if it's see-through? Is that necessary... 🫢
1) Not all containers are clear.
2) When the pigment settles, it’s hard to see from the top when they’re stored in a box.
3) When the pigment settles, it can look a different color.
4) Dried paint can have a different hue than wet paint in a jar.
