How To - Seal EVA Foam Props & Costumes with Neoprene - Creature Cast 

As a cosplayer, I don't know how I had never heard of this channel till I saw it in Jazza's blog but this has to be one of the most useful channels ever on the face of youtube. I'm coming here when stuck on something from now on. I JUST LEARNED HOW TO PROPERLY SEAL FOAM AND I'M HYPED!

a fun thing with the latex is that you can brush on powder pigments while it's still tacky. It'll detack your surface and give a pretty spiffy finish. I've only done this with metallics (both solid and color-shift) though, so Idunno how matte the finish would be with, say, a plain carbon black. And no, after you give it a quick rubdown with a soft, lintless cloth, it won't rub off on you.

I used Creature Cast today and it is such an amazing product. It goes on easy and covers a lot of area with very little. I only used 2 coats but it was enough for my project. Thanks for the video!

Thanks Bill! This is exactly what I needed for a costume I'm working on right now!

Bill thanks for posting this video I went out and got some creature cast and the thickening agent. I started using it and I will never look back. Thanks again!

Love the idea you put together for your spray painting station with the fan, window and airfilter. Great job on the video keep em coming. Again as always you guys rock.

Woot! More foam sealing! Thank you Bill!

Nice to see more examples of neoprene, I remember evil ted mentioned creature cast in one of his videos and it looks like a lot of fun to play around with. Very informative video.

Bill thank you so much for all you share. I'm adapting the skyrim armor for a steampunk application as well as my first self designed and fabricated costume. My daughter wants a Tin Woodsman. Again, y'all rock and I hope you're at Dragon*Con this year!

Thanks Man! I need to make a new helmet and this series is super helpful. Also that foam smith book rocks.

I'm super enjoying the tutorials. I'm diving into EVA currently. A friend mentioned plastidip for sealing. I was wondering what your input on this verses the ones you mention. Thanks!

your videos are the best and the neoprene sealant looks crazy , I loved it, but was wondering what are other options in case I cant get it or dont have enough money!?

Thanks for this Bill!

Such an amazing and helpful channel

Cool tips Bill, thanks.

sweet, new video!!!

I've been wanting to use neoprene to seal props and such for my comissions! I like that it can be sanded to get rid of imperfections of the surface. If you happen to see this, would you still recommend it as a primer?

Hey Punished Props, (or anyone that stumbles across this), this May sound like a very silly question. Could you use a HVLP spray gun to prevent that “shoot gun” over spray? I’m just trying to mitigate the amount of sanding to get that smooth surface.

Any alternatives to this that would be available in Europe? Would urethane rubber work as well and be sandable or is it more like latex?

6:24 Can you please show us how to make an EVA foam rider cap like what's on the head form?

I know that you've probably talked about your spray gun in earlier episodes, any chance you can pass that along once more? I really like the "mason jar" for the spray can.

Did you use acetone to clean spray gun? also which sprayer are you using? New to hobby...

You and Evil Ted have been great for a Father of and Avid Comic Reader. We have a Local Comic Book Start Up Store my Son has recently become a patron of. They put on their first Comic Con Mini this past weekend. He was very pleased to walk in with his Deadpool Costume good old Dad made for him including a EVA Foam Helmet. He was the star of the show and everyone asked how I was able to make such a Rad Costume. I simply said "RU-vid Punished Props and Evil Ted are your Two stops you need to check out". Anyway... Thanks for all of the Help on his costume. Halloween is coming up and Star Wars is calling my Name. I may try my hand at Sintra fabrication this time as I desperately want a Mando Costume for myself. I would love to see you do some Sintra tutorials soon.

hello bill :) have you try to seal with the new " flexipaint"? look like it's a great product to avoid crack e wrinkles

UM. ORDERING THIS RIGHT NOW!!!

Good stuff there, Bill; ordering my batch worth of the stuff too. But estimated, what was the dry time between coats when you did it?

Still pretty new to cosplay builds, but would general big box store spray paints work on this after finishing as well? Definitely sold on this vs latex rubber if it takes acrylic easier.

could you please make yondu's original fin from gaurdians of the galaxy?!

If we aren't as well stocked with a spray applicator, would it be safe to say you could brush on thin layers of creaturecast and sand back any heinous beush strokes? Looking at options--loving these videos!

What psi do you use on your air compressor for spraying this onto a project?

yeah!second to comment. love the video, ive been trying to find a good sealer

Does creature cast need silicone sprayed on to it to keep it from cracking like how latex and plasti-dip do? And is creature cast soft enough to hit people with, would it be suitable for a LARP weapon?

you're awesome thank you for the tutorials! I do have a question though. You mentioned that Bondo is easier to smooth out or to blend in, but does Bondo not work well with foam? why do u prefer the kwik seal on this material over the Bondo?

What's the psi on your compressor for that sprayer? I'm thinking of buying a unit, but not sure what to buy. Theoretically I'd like something that would spray silicone (EcoFlex or DragonSkin), but wanted your opinion of what would push this neoprene. Thanks.

Hey Bill & Brit! Any idea if you can use creature cast rubber on rigid insulation foam? I'm wondering weather it contains compounds similar to barge cement that may melt it if I try to coat it. Thanks!!

im yet again impressed but it might be because its 2am in belgium, i wish you had a template for 15thc medieval armour

I know you've covered how to do it digitally but could you do a more in-depth tutorial on up-scaling patterns by hand?

Hi there! Is there another substitute for the rubber? I'd love to use it but I live pretty far away and shipping costs are expensive? Maybe I can get something similar. Is this the same they use for neoprene suits? Sorry if it's a dumb question

Hey Bill, I'm making a full head helmet for a costume and I need some advise on what I should seal it with. I'm trying to get a semi-gloss metallic look, with no natural texture, that can be weathered and painted. I need the helmet to be able to withstand the abuse of being worn in hot outdoor elements and not crack if it is stretched when being put on. Would you recommend plasti-dip, neoprene, epsilon or silicone to seal the foam?

Can you let Creature cast completely dry before adding another layer on it or do you still want it slightly tacky the way Evil Ted says to do with latex

how do you go about making a STARWARS stormtrooper helmet?

Hi Bill! Do you plan on sharing how you put together the Voltron helmet? I believe you built it a Silicon Valley Comic Con, but didn't film it. Will it be shared on Tested in the future? I'm most interested how you constructed the groove in the back. Thanks!

Daaamn this stuff seems awesome! Would you say the spray gun is somewhat essential, or does it just help make application easier? Cuz if its not essential, I may have to get some of this Edit: Just looked up the product information. Spraying does not appear to be necessary

Does this stuff stick to 3D printed ABS or PLA? I'd love to toughen up an upcoming print.

Chinbeard the patron saint of sanding. 0:-)

hello i am fairly new at this i am planing on making a destiny warlock helmet with foam, but like i do not have much money to but fancy stuff. what can i use to seal the foam to make it kinda plastic ish and stil be able to spray paint? i heard about plasti dip?

Does Neoprene have the same flexible properties as latex? I use latex to skin my upholstery monster costumes.I don't think I am allergic to latex, but it does make me feel bad working with it. Would neoprene be a good alternative?

The second layer didn't go on so well, right? I tried it last night, and it seems like it'll pool on if the underlying layers are already dry. If brushed on before the underlying layer is fully dry, I ended up with more visible brush strokes.

hey I got a question. if i were to do this, how durable would this be? can I give it a beating or would I be better off using fiberglass?

nice

anyone know if this stuff can be shipoed to alaska? I cant even order solar generators because of the batteries. :( does this count as a hazardous material? Thanks for the video! love em

Does anyone know if you can get this in the UK?

Cool

dude is there any chance you could do a tutorial on a power ranger helmet perhaps out of EVA foam ? I've been incapable of finding anything helpful

Can you use rubber cement paint over the liquid neoprene ??

Is it okay to hit the kwik sealed foam with heat?? I hear it re-opens up your seams.

Do you thin the neoprene before your spray it? Do you use water, water with ammonia (like latex), or something else?

I do indeed have latex allergy, so this is handy. Availability in Australia? Also been wanting to try the "chipped paint" look. I can't use latex, I can't use mustard. I've heard toothpaste could be used for this?

Please do nova's helmet please😀

The website says the neoprene can be polished with a felt wheel or acetone, any luck attempting this?

Without sanding it would look great as galvanized steel! Just throw some silver rub n buff on it and add some weathering!

Would i be able to just brush on all my layers and then sand it down so i dont see any brush strokes?

right now i m on way to make the elit knight armor from dark souls but i dont now how to make the helmet (because it's made of 3 parts that 2 are the visor) please help. pd:And sorry for my english i'm not native.

What would you say is the best option for someone to seal EVA if they don't have access to an air compressor?

do the Daredevil helmet!!

Hi from france this one is only available in USA, sad.

will rattle can spray paints adhere well to this without cracking?

So how far does 1 gallon go? Will it cover a full costume like Master Chief? Or will it last for multiple costumes?

It looks like Creature Cast says you can apply it with an airbrush. I see you use your Critter gun, have you tried it with an airbrush?

Is there an Australian alternative?

How is Plastidip compared to this? thanks

Can't help but notice that according to their website it says that it can be chemically smoothed with acetone. :thinking:

Isn't Plastidip good enough?

cool videos. Would it be a good idea to start sealing and then use the filler? Or maybe mix some of the sealer into your filling compound? Only reason I ask is because you don't seem to be happy with how it worked out in the previous video.

I'm making a prop and I'm using insulation foam and I have to make a curved cut all I have is a utility knife it's kinda hard ,any tips?

$75 a gallon?!

I will quite my life and work for you

We should meet up sometime! I live just north of you

so distracted by the over exaggerated hand movements - but great content!

I'm not a millionaire, so I think I'll just stick with Mod Podge and Plastidip for now...
