What kind of plastic do you have? I am trying to find a way to paint plastic molded chairs and I have gotten a variety of responses form local artists that might help you. Some hobby shops carry paint for painting plastic models (airplanes, cars, etc.), but it depends on the type of plastic that you are trying to paint.

If you could give more details, I might be able to help.

Jenni, as Myra said, you really should know WHICH plastic you are talking about.

There are many 'plastics' just as there are many 'metals'. Some don't take kindly to painting, ie. Teflon but also Polypropylene and Polyethylene (PE), and PE has a waxy feel, anyhow (super for fridge ice cube holders etc. etc) So what have you got? PP or PE will both slowly burn and will both drip. PE will always smell of candle wax. Cut off a sliver and put a match to it to try this out. If you have PVC, Acrylic (ie. plexiglass) or ABS or variations of these, these thermoplastics can be cemented so then consider a paint that will 'attack' the plastic, ie. a lacquer and not a latex. The test for these is simple. PVC doesn't burn, it just gets soft and stinks. Acrylics burn slowly and smell sweet. ABS burns quite well and gives off black fumes and it pongs.

Myra's deck chairs are made, I'm pretty sure, of an impact modified PVC although perhaps manufacturers might use a UV stabilized ABS. ABS is weaker than PVC (not as rigid) but is much better on impact. Anyhow, dammit, when the chairs were bought, the packing would SURELY show what material they were made from. Fortunately no one is making items from a super plastic called Cellulose Nitrate (hence the film name of celluloid) as that REALLY burns. Dangerous. But super for ping pong balls which, although modified with Naptha, cannot be excelled by any other known plastic.

Lastly, please preclean before painting. To get a better job of adhesion, sand down very slightly, too.

Cheers!

A 2K urethane works on most plastics with the exception of polyolefins (polypropylene or polyethylene) these require a special epoxy that needs a 250 ェ bake to activate after application.

Hi,

I was just wondering if anybody out there knew how to paint plastic, because I'm redoing an old snowmobile and I would like to know how to go about finishing the hood of it. Any help would be rather helpful.

Thank u!

I stunt motorcycles. Meaning I break plastic on a daily basis... first off, like Mr Freeman said, know what you are painting. and hope it is ABS... abs is most common for sportbikes/snowmobiles. Polywhatever is used on dirtbikes/atvs... obviously, this is not written in stone. I wouldn't recommend painting a poly part, just replace it; it is a lot cheaper than abs. If you're not sure, abs is quite rigid, poly is malleable to the extent that you could almost bend it in half without breaking it, depending on thickness of course. What's going to happen if you paint something thats hella flimsy? Kurt lammon writes the best book I've seen about plastic repair/painting... if you want to save some cash and experiment a little... here's a tutorial http://www.sportrider.com/tech/146_0204_body/ this is one of the cheapest places to get plastic welding supplies, short of finding the crap on ebay ---> >

http://www.aircraftspruce.com/catalog/cmpages/plasticrepair.php you'll have better luck if your plastic doesn't have pigment in it. sand it smooth, soap and water, weld your cracks, krylon primer, Krylon Fusion , and then throw it on the pavement at 40 mph again... repeat...

...Funny...I was just tackling that very job and ran into the same problem. I called a friend of mine and he said you have to sand any plastic surface before you attempt to paint it. Then apply a plastic primer, then your paint. (specifically made for plastic).
Good luck. I am taking his advice, and will let you know the results.

I am planning on painting a stripe on a Sears cartop carrier. I have been told that there is a hardener to use that is for plastic car bumpers. Anyone know anything about this?

I want to paint these plastic cubes that I use to teach in a math class. The material is somewhat shiny and smooth. I've tried acrylic and it peeled off. Any suggestions?

Krylon Fusion Plastic Paint claims there's no priming, chipping, it adheres and dries in an hour. Maybe this will work....

I want to paint and decorate a plastic see thru sheet, like a vinyl shower curtain! Does anyone know what I can use so that the paint doesn't crack or chip?

Thanks!

I just bought a 98 ez-go golf cart. It has some scratches on it and one actually dug a little into the plastic body. I want to repaint it but not sure of how to fill in the scratch that dug in the body or how I should go about painting it and what type of paint to use.

Hi,
I would like to attempt painting small objects on a plastic film. I would need to use a variety of vibrant colors. Can anyone out there help with some answers? Like maybe an artist who paints on clear plastic film...Is there a particular brand of paint that I need to use, hopefully one that carries a wide variety of colors?
Thanks!

I am having a problem getting a durable finish on ABS body panels off a motorcycle. I am thinking of trying the Krylon Fusion and if it is durable topcoating with a clearcoat for better protection against chemicals that might come into contact with the finish. I see suggestions to primer and then use Krylon Fusion. Isn't the whole idea behind the Krylon Fusion that it bonds with the plastic better than conventional paints (and presumably primers)? If you primer then the Fusion paint technically never touches the plastic so what would the point be? Couldn't you use just about any flexible paint if you bothered to use a good primer that bonded well to the plastic? In a nutshell - Why would you use Fusion after primering?

For those of you out there trying to paint shower curtains, vinyl tablecloths and the like, Plaid has a paint line for plastic. It has like 37 different colors. I can find a small assortment at my local craft store.....but you can buy the whole line primer sealer and all at their web site. I recently made a custom picnic set table cloth, dishes and all. It has with stood even the dishwasher! Hope this helps.
