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

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

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

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

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.

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

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

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

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.

very interesting.will try it thank you

Always face the cutting blade edge away from yourself

NEVER cut TOWARD the fingers !!

O yeah that total genius straight up awesome 👍 thanks .

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

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!

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

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 😀😀💡💡!!!!!!

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.

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