How to Make a Paint Sprayer From Plastic Bottles, Plastic Bottle Hack

- This is a how to instructional video on how to make a pretty good performing paint sprayer from two plastic bottles, a couple of straws, and some PVC pipe.
The paint sprayer will require some sort of compressed air. My design in this video requires a shop vac that can blow. One could also use an air compressor or some other sort of blower such as a mattress inflater.
I came up with this specific design while playing and experimenting in my garage. My design allows the paint to be aerosolized by the compressed air giving an even conical spray pattern. This is due to the position and orientation of the straws. I found that when the "sipper" straw is cut at a 45 degree angle and faces the oncoming compressed air, it produces the best results. The spray nozzle also must not extend too far past the sipper otherwise splatter will occur.
This paint sprayer requires a bubble tea straw (fat straw), a normal drinking straw, two ~6 inch sections of 1 1/4" Plastic PVC pipe, and two plastic bottles. 1 Liter sizes seem to work best but it can be scaled up or down. The plastic bottle should have about a 1" diameter neck and should be flexible enough to squeeze.
This paint sprayer can handle out of the can latex paint without needing any dilution with water. Just ensure the paint is properly mixed.
The great advantage of this design is that it is incredibly cheap to make, allows ease of refilling, and ease of cleanup (simply throw the bottle away and make a few more bottles with spray nozzles for next time).
When using the paint sprayer, the paint should be mixed and funneled into the plastic bottle. The cap/nozzle should be firmly attached and the bottle secured to the handle via a rubber band.
To operate the paint sprayer, the paint sprayer is held bottle side towards the ground. The shop vac is then turned on. When ready to paint, the paint sprayer is turned upside down so the bottle faces the sky. Then the bottle is lightly squeezed to dispense the paint in order to spray it. When done spraying, the spray gun must be turned bottle side down before the air is shut off in order to prevent paint spatter as the shop vac slows down.
If water like consistency paint is being sprayed, you can use the same
nozzle configuration but it may be more advantageous to use a coffee stirrer straw as the sipper and a regular sized straw as the air nozzle. Also if thin paint is used, you can extend the sipper straw so it reaches towards the bottom of the bottle and also drill an extra hole at the bottle cap for an air hole. This way the thin paint would be dispenses solely from the venturi effect and the paint sprayer would not have to be turned upside down and squeezed. Or yet another option is to omit the air hole, extend the straw to the bottom of the bottle and squeeze the bottle while it is still oriented towards the ground.
An important reminder is to ensure that the paint sprayer is attached to the blowing side of the shop vac and not the suction side. Otherwise, the shop vac will suck all the paint out of the bottle and into the shop vac.
This design isn't limited to spraying paint. One could spray varnish, stain, oil, or fuel (flamethrower?)... as in a waste oil furnace configuration.
Worked for me. Used my vacuum cleaner (out) and bottle in the same 45 degree angle. Thanks for the tip.
Excellent!
I think this wizard just saved me $400 on an airless from Hell Depot, Much praise upon you, paint necromancer.
Hahaha you're welcome. I love this name paint necromancer. Make sure to do a test run, it can make a huge mess
Best thing I've seen all day.. Nice
So im gonna use your idea but with a hair dryer instead as it already has that circular look and size to attach a hose.
I also want to test if the hair dryer on its lowest mild heat settings has an effect on the paint quality.
And im gonna make it a little stronger.
Nuff Respect to you and your idea.
It's not going to work with hair dryer, it's air flow is not sufficient enough
I like this idea maybe I can use this idea and improve a little bit more for a temporary stucco spray, I have few yards to spray at my new storage :D thanks!
good idea thanks
Have u done a air compressor on yet??
How do you do it with compressor plz make video love the idea and watching it work blows my mind
Hi thank you for the nice comment. I will put it in the queue to make another video about the paint sprayer. I think with a compressor it may be even easier as the air hose from the air compressor would simply attached to the large straw directly instead of through the handle.
cool brother i cant wait
Just a tip when using a Combination Square for Layout marks the sliding Ruler / StraightbEdge is one inch tall so you don’t need to measure and mark that just mark one side put it in place and draw your layout on both sides of the Square i am a retired Professional Woodworker and with the exception of some Cmbination Square toys Ivecseen all the others i’ve ever Owned or used from name brand Companies are 1 “ as a Matter Of Fact most Layout tools are standard widrhscand thicknesses as Well which Allows the Craftsmen to be faster and more Accurate when doing Layouts things like Framing Squares are built to match the typical thicknesses of todays Dimensional Framing Lumber so they can mark tooth sides of where a Stud ,Joist ,orvTruss belongs on the Project. this process gives the Carpenters the Advantage of being able to ensure things are built to code or more accurately when Assembling the Projects they are working on
Thank you for this time saving tip! I will remember this one. I'm always humbled and grateful when I get to learn things from people who are masters in their craft. I only get so far with my middle school wood shop class basics.
Thanks!
Nice idea and skill. 👍👏
Good
good idea, il try my own later, thanks
Geeze I thought it was an asthma pump 😂
This would certainly make asthma worse haha:)
Can a vacuum cleaner we use in our home b used in place of inflator
jeetendra kumar pallai you could but it would require taking apart the vacuum, extracting the motor and building a box around it. i did this in my other video of my diy shopvac with secondary water filtration
Air through machine se vaccume clenar kaise banae plzz suggests me
like the idea, subbed
Thank you!
Thanks!!
Very very nice bro tq
Love this video and i subscribe.
Thank you so much! I hope to make more videos of same or better caliber
I bought a paint spray machine.but no need to everyday paint.
How can I use a vaccume clenar plzz help me
Hi sardaar Khan, the easiest way is to use a shop vacuum and follow the instructions in this video. Otherwise if you have an ordinary vacuum that you are willing to take apart and extract the motor, you would have to build a sealed box around the vacuum motor to get suction and blowing functions. You can see how I made a box around a vacuum motor in this video th-cam.com/video/bS2QPDEt284/w-d-xo.html
My machine is only air flow not creat vaccume air to suck a dust.
Panit spray machine the just through a air
Hi Sir im trying to build a smoker device with filtration system, im going to adopt your electrostatic precipitator with activated carbon. Pls support my project if I can have some link on how I would do it on working process..
Hello Romuel, sure thing. Here is a link to instructions on how to build one. hackaday.io/project/7237-household-electrically-enhanced-wet-scrubber
Locke Lab thank you
But it is not strong
Its meant to work well enough for one or two jobs. Then throw it away the plastic bottle part and make another one for a different color or different project.
Thank you so much now I am going to make it ......
🤣
to much time on your hands..
thanks for watching :)
ALL THE BEST FROM iRELAND
This isn't very practical. Entirely too much work for such mediocre results, and besides...spray paint is cheap
Thanks Tony for commenting. I don't disagree, it was more of a solution to a non-existing problem. I had a pile of plastic bottles and was playing with what can I build from plastic bottles that wasn't already done on the net. A paintbrush usually is quicker in terms of setup and cleanup. Stay safe out there.
@@LockeLaboratory Haha, I hear ya on the pile of plastic bottles. Earlier today, I grabbed my heat gun and made my pile a little smaller by fabricating some shop vac adapters...🤷♂️
Tony Snyder thats actually a great idea for using bottles. I'll have to remember that for my next shop vac project.
