How to Make Liquid Plastic! The Easiest Way to Fix All Broken Plastic 

I used this along with some window screen to patch a gray water tank in a RV years ago. held better than any patch!

If you need specific colours Lego blocks disolve well in acetone.

Just a tip if you rub wax onto a part that doesn't need to be fixed but you want the same surface finish in your repair you can use hot glue in the undamaged area to take an impression of the surface and then use the hardened hot glue as one of your repair sides and you will get a near seamless repair. As far as using the ABS it's fine as long as your in a well ventilated area and using proper PPE. Plus you will get a better molecular bond using the same material and a matching color. Which is better then Epoxy.

I just use baking soda and super glue. Instant fix with no waiting for hours at end for acetone to do its thing with plastic.

it's not for all the plastic (hence you can see as he does using plastic cup for) and in case you will combine different tipe of plastic, it won't bond too much well, but for those, what can be melted by acetone or somehow reacts with (PVC, ABS, polystyren) it's nice tip, actually.

My current favorite plastic glue is permatex plastic weld but I'll have to give this a try. Thanks!

This works equally well with PMMA/Acrylic/Perspex as it does with PC as shown. I have been doing this to make specialty mixes of PMMA weld. Be advised that with PMMA or PC you want to make your donor chips as small as possible. With softer plastics such as PC, you can use a cheese grater or with harder plastics such as PMMA you could use a metal file. Beware that with PMMA, crazing is possible with extruded sheet. Best results are found when welding cast PMMA.

Questions about your idea here I like it lots why not weld it ? Will the asitone work on all plastics? Some plastics are meant to with stand harsh chemicals like that of asitone And about how long will it take for the slurry project to dry or cure completely? Love the idea 😀😀💡💡!!!!!!

A great idea for plastics that can dissolve in acetone, but YIKES! I have a very nice scar on the knuckle of my left index finger where the blade went down to the bone from doing what you are doing at 6:09.

Hi Gaus. ABS plastic dissolved in acetone releases styrene which is carcinogenic. I recommend using two-component epoxy resin. It reconstructs the missing parts better and has no health risks

I use Permatex Plastic Welder. It’s black, hardens like a rock in 10 min and can be drilled, sanded and filed.

Gracias por compartir...saludos desde México...

very interesting.will try it thank you

Always face the cutting blade edge away from yourself

😮 Muchas gracias por esos consejos pero una pregunta y el plástico donde se echa no se derrite 👍

O yeah that total genius straight up awesome 👍 thanks .

Great job, bro. Well done. Some bumpers are manufactured with Fibre Glass materials..Some bumpers use PP or other plastic materials. Take note.

Acetone + plastic is a well known "glue" for model makers

I've tried pa n pa+ n regular plastic. Having trouble melting. Any ideas? Same recipe. Does jar need air why you put paper under the top? Thanks

NEVER cut TOWARD the fingers !!

Cutting with knife with the sharp blade side into you - amazing idea!

Can you use plastic bottles too? I do mold making & I bet too this would also work too instead of resin.

Es importante saber que los plásticos no son todos iguales, los hay de muchos materiales diferentes y aunque cuesta de creer, si intentas unir plásticos de diferentes materiales NUNCA se van a unir. Buen vídeo!

Thanks for your video, it shows resourcefulness. Disposable minds people won't like it; "right to repair guys" will love it. One caveat: it only applies to *some* plastics, those which can be dissolved in acetone themselves. Clearly syringe, adhesive tape and acetone bottle (I guess polycarbonate) do not. But it applies to *many* everyday items. You should add an extra adhesive bead on the outside of that battery case. Congratulations.

La mezcla funcionaria?, si en lugar de acetona, se utilizara disolvente universal

very informative. thank you. i will try this on cracked fairings of my scooter

Mate tnx for the video. The syringe is how many ml? 50ml?

Fenomenal, gracias ❤

El del ventilador del fancooler me deja pensativo si al derretir él plástico como líquido perdería propiedades de resistencia, por ello no sé los expertos aquí me guíen si, sería conveniente mezclar ese plástico líquido con otro componente químico y así tenga mayor durabilidad, igual el video me está dando la idea para reparar una pieza de notebook, en especifico el mecanismo de la tecla el cual se partió un pasador o lengueta.... Intentaré a ver qué pasa ojalá funcione por muy largo tiempo... Gracias por el video

I love your repair videos 👍 But I am still working with crazy glue and baking soda which I use to fix everything :-)

La idea de hacer plástico diluido con acetona es genial lo único deficiente fue la forma como manipulates el trabajo no fue nada desprolijo se vio que estabas muy nervioso pero igual se te dan las gracias por esa buena idea saludos desde Chile

👍👍👍. Thanks

Yeah, cutting toward your hand with a sharp blade. That’s real smart.

เยี่ยม

Friend, aviation shears or tip snips would save you some effort and time. Keep trucking,nice video.

Tremenda idea

How strong are the resulting patch ups?

شكرا على هذا الفيديو....

فكرة مدهشه .

Nice idea 😊

bravissimo!!🤩

which is better acetone or thiner PU .. ??

Se puede lijar?

Is there anything else I can use besides Acetone to liquify the plastic?? Like maybe paint thinner?

Klasse muss ich gleich mal probieren Plastik kleben ist immer heikel

W O W !!! its really??? Nice!!! thanks mate!! :)

I have to wonder why the acetone didn't affect the plastic water bottle he had it in or the plastic jar he dissolved his mixture in?

You are using a plastic container and a plastic syringe as well. Aren't they affected by the dissolving properties of the Acetone?

Hola buenas tardes, una pregunta que tipo de plástico debe de ser porque yo tome unas tapaderas de refresco le puse acetona y no se hizo plástico líquido.

Excellent

Plastic welding doesn't weaken the plastic like this does.

Super genial

I tried this to repair the front windscreen under the bumper on my truck and a couple other things around the garage and it seems that everything plastic I need to repair does not dissolve in acetone so this is useless to me and I used the old faithful JB Weld plastic bonder.

Gracias por compartir los conocimientos...en caso que no tengas paga comercial... La pega de plástico fuerte en Venezuela solo vale 3 dólares y es muy fuerte quiero saber si estás soldaduras son igualmente bien fuertes.? La acetona es igual o más costosa que esa pega fuerte...

プラモデルが欠けた時に断熱材のスタイロフォームを塗装の薄め液で溶かして使ってました。発泡プラスチックなので速攻で溶けて便利ですが色が青いので塗装を前提としてしか使えなかったです笑

Brilliant

Genial gracias 😮😮😮

Only works with ABS. Instead if Acetone you might as well use MEK (methyl ethyl keton)

Game changer!

Well done. Looks interesting but howcome acetone does not harm the plastic jar and the plastic syringe?

アセトンで溶かしたプラスチックは乾いていても上から塗装すると塗料が乾いてからも浮いてくるんですよね。

What specific plastic type to fix hole (fill low spot) on car plastic bumper?

Aquí, en Argentina, es bastante difícil conseguir acetona técnica por su alta toxicidad (fumar no está prohibido). Para estos arreglos pequeños yo uso grafito (el que se usa para lubricar cerraduras) y cianocrilato. El resultado es fortísimo y se pega a cualquier plástico hasta los pinchazos en colchones inflables...

Nice idea, something to keep around for quick repairs when epoxy or plastic welding isnt available. And for all those remarks about hiw you were cutting towards yourself...us paramedics dont mind... Just kidding. I try to cut away but I have learned a lesson or two in my life cutting the wrong way and will probably have to learn it again before I die. I dint think anyone can say they have never dine it.

welldone, please guide silicon tubes will dissolve in action

Me gustó mucho tu video , disculpa mi sugerencia, tu no explicaste que clase de plástico estas usando, hay plástico que el acetona no lo deshace, porque hay botellas de plástico que contienen acetona, en mi caso si se que clase estas usando, pero las demás personas, por ejemplo las sillas de plástico, esas no se pueden hacer líquido, saludos.

Acetone melts the car plastic but not the plastic container...????

Haces la mezcla de acetona y plástico en un bote de? Plástico o cristal? Por que parece de Plástico y no se funde, por que?

Can PVC be used?

Why didn't the plastic bottle you used to mix the plastic with acetone melt? After all, it's also made of plastic, right?

손동작이 어슬프네요..하지만 아이디어는 좋아요.

Si se ve bien pero porque la acetona no derrite al embase de plástico en el cual se hace la fucion del otro plástico?

To all those who are wondering why the plastic you chose isn't melting or if all plastics can be used Acetone will dissolve PVDF, polycarbonate, Polysulfone, Acrylic, PVC, CPVC. It will NOT dissolve FEP, PFA, ETFE, ECTFE, PCTFE, PEEK, Polypropylene If you use plastic that can dissolve in Acetone and apply it to any other plastic that dissolves in Acetone the residual acetone in your melted mixture will help to melt the edges of the plastic you're applying to and makes it very close to original strength. For other plastics, if you have a small area you need to repair, go grab some T Plus 2 Pipe Thread Sealant from the plumbers section of your hardware store. I know it says thread sealant but trust me, it will work for plastics fantastically. If you're trying to repair a large area, then look up how professionals repair plastic trim on vehicles and apply that technique to the large area you need to fix.

Very good

We got the point after the first four cuts.

I have tried melting CD case with Acetone (pure) and it will be more like chewing gum than liquid plastic. What am i doing wrong? I put it in a syringe like you do.

Este metodo solo funciona para plasticos con acetaro o vinil

Can you do that to rubber. To repair boots heels

Nice ❤❤

The video I'm watching he is not using a knife to cut toward himself like some are saying on here, he is using side cutters. But great video!

Chemicals are always dangerous. At least useful as one of the efforts to reduce plastic waste. And care is required for any handwork

good idea. I used to use epoxy resin. But one cannot thermal melt resin with plastic.

Terimakasih

Bonjour, cela paraît vraiment intéressant, il faudra que j'essaye. - Mais l'usage de l'acétone (1:02), doit s'accompagner de nombreuses précautions et c'est de votre responsabilité de le signaler clairement. On voit bien vos gants, mais on ne sait pas si vous travaillez dans une pièce aérée par exemple, loin de toute flamme, etc. Par exemple vous pourriez écrire : "avant d'utiliser l'acétone, veuillez prendre connaissance des précautions d'emploi signalées par le fabricant."

Me dá curiosidad porqué no se derritió el contenedor de plástico? 🤔

Excellent video. Ruined for me by the high-pitched, loud DING at the end. Tinnitus.

Always cut away from yourself...

👍👍👍👍👍

Not every plastic dissilves well in acetone, what type of plastic material is easily dissolved in acetone ?

Ahora mostrame como fundis el polipropileno!!!!!!!!

Could have used a better sound track in the background

القنينة بلاستك لماذا لاتذوب

Oh maaan ... when I see someone using a blade against his fingers I know he is a joke ... kids, never do this!!!

プラリペアより安価でいいですね。

If it works for you great. But I’ve been repairing different plastics for years and I don’t see how your seems aren’t brittle and will fail under a load. But if they work for you,good on you. But be careful with that straight edge pal,cut away from yourself and body parts and don’t make a habit of breathing that mixture

te juro que si me ayuda te agradecere toda la vida

La acetona no derrite el vaso de plástico??

You say "from bumpers" but bumpers are usually Urethane...and you never USED a bumper for your material, looks like ABS fender liner or similar. Still good ideas.

Qualsiasi tipo di acetone?.

Ever heard of scissors ?
