Restoring stadium seats | Flame Polishing

- The flame melts the surface of the plastic making it smooth and shiny. This is called flame polishing.
The original color is red. When wear and tear occurs it leaves smalls scratches that cloud the surface making it look pale. When the scratches are melted away there is no more cloudiness and discoloration.
In addition to scratches, the plastic resin has become oxidized due to UV exposure (these seats probably get lots of sunshine!). Red pigment is really hard to protect, and with heavy UV exposure it turns cloudy (paint on red cars can also suffer the same problem).
This torch is melting away the oxidized top layer, allowing fresh red plastic to flow across the surface.
So, this opaque look in thermoplastic materials is caused by crystallization which may be caused by stress or UV- radiation. This is the same mechanism that colors your drink cap white when you scratch it with your finger. The dye is not lost but becomes less visible due to the crystals scattering the light instead of absorbing it (the parts of it that isn't red light). Heating the material up above its glass transition temperature breaks these crystals and the original structure is restored, letting the material once again reflect only the red light.

Wikipedia:
Fire polishing, also known as flame polishing, is a method of polishing a material, usually glass or thermoplastics, by exposing it to a flame or heat. When the surface of the material briefly melts, surface tension smooths the surface. Operator skill is critical with this method. When done properly, flame plastic polishing produces the clearest finish, especially when polishing acrylic. This method is most applicable to flat external surfaces. Flame polishing is frequently used in acrylic plastic fabrication because of its high speed compared to abrasive methods. In this application, an oxyhydrogen torch is typically used, one reason being that the flame chemistry is unlikely to contaminate the plastic.

I wish I had some oxidized stadium seats and a flamethrower in my life.
Right? I bet that's a nice feeling.
I found it very satisfying
Those seats aren't oxidized. The surfaces of the seats have undergone UV attack that has split the polymer chains and causes incidental light to refract.
Melting the surface of the seats realigns the polymer chains so they are contiguous again, reflecting light instead of refracting it.
You're welcome.
I've used this method numerous times to restore weather-beaten automotive plastics and trim; works every time and looks like new!
I love this method🙌🏼
Thanks for the idea. Does the plastic stay nice over time, or does it deteriorate rather quickly?
@@pieterv6984 I'm here with the same question. I'm thinking you may have to add your own top coating of some kind.
I’ve done this for years on plastic car parts.people are amazed at the difference,but I never tell them how’s it’s done.our little secret.
@@pieterv6984 , in my experience, it's a long-term fix👍🏼 also, I use a heat gun as I don't have a flamethrower ready at hand
Nice
Tried this with my house. It burnt to the ground.
Forget about pressure washers, start cleaning with a flamethrower
@@zlmdragon. Burns everything off, re-melts the outer plastic and kills any germs. Sounds clean.
I really want to do that for a while. It looks to be satisfying and a bit of a stress reliever. Well, probably for 30 minutes or so, and then my arm would start to get sore!
@@zlmdragon. I could, but I’m right-handed! Don’t know how heavy that equipment is, but I am sure my left arm would start shaking! 🤣
Actually brilliant.
Man is this satisfying. 😩
From new to old back to new.cleverness.
Get ready for the million comments from old guys who have been doing this for years
Rare case of really interesting and educational TikTok content.
Yeah but there is is big but. The seats will get their color back but they will not as you can see keep being shinny after the heat treatment. They become matte not glossy just so you know.
SO CLEVER
How often can you do this? Surely it must damage the plastic over repeated meltings.
Do you think a torch would work?
I use this method on my toe nails
now just 49998 to go!
Would this work on my sport court?
Reminds me of my first day at school and I forgot my lunch box and had to pretend it was ok in front of the other kids
I tried a thermal gun. Me seats looks like new but they broke in pieces when used
Is a reducing atmosphere of a fuel-rich flame necessary for proper results, or would an electric heat gun work just as well if powerful enough?
Over 3/4 of the energry made in the US is still made with fossil fuels. Just cause something is electric doesnt mean its better for the atmosphere or the environment in general
I think you are completely misunderstanding the point of my comment. I'm interested in the chemical reaction taking place on the surface of the seats being restored not what the source of the energy of the heat used to cause that reaction. Have a nice day.@@Level99Dab
@@williamreymond2669 Sorry for the misunderstanding. I was under the impression that you believed electric heating would be more environmentally friendly for this particular job. And if you were aware of the statistic I stated, then I apologize for assuming you didn't. Thank you! You have a nice day as well
I don't believe so; I've seen other videos where people do this with the workpiece never entering the flame
@@Rabbitflyer5 Thanks, finally an answer.
Oh... now I understand why hooligans do that
Anyone tried this? No chemical or paint???

We really don’t need the two panels on the side…
Hope they would not be rough to sit on, and sticky..
Very odd that they never show the after seat the next month or even the next day. I could show a video of me rubbing spit onto a scratch on my car and it would make it as new.

Hello new subscriner here
Only 49,498 to go
This channel has to have a shit ton of sub bots, it gains so much subs in so little time but despite that it take more than a 12 hours for them to get 1k views and even some videos on my channel get more than 1k views in 12 hours I only have 1.6k subs and they have almost 1 MILLION.
This guy will wonder why he has cancer in 20 years
Oh no! Melting the top layer of plastic in the open air! How dangerous!!!
Typically done after a Nikki Minaj concert.
I tried this on my wife....It didnt work.
Try again with ear plugs and more heat
@@aanderson8884 😆🤣.
No re.
Wives are sweet.
Only one is their in the whole world.
Needs to learn how to properly care for them 😄
Really toxic
lmao sure
Terrible idea
