How to make Props with Plastidip and Foam Sheets by RuffleButtCosplay

Would i be able to make Marshmellos helmet with this stuff? Ive been told a bucket works but its not gonna give me an exact same look, im trying to make an exact replica.

I tried this on craft foam sheets and they just soaked up the plastidip and it didn't look anything like yours. Any idea what went wrong?

Where did you get your Eva Foam? It looks like you got the 1/4 inch instead of the 1/2 inch. I'm looking for the 1/4 inch because I need thinner Eva foam that can bend a little more.
Please get back to me soon, and thanks for reading my comment!

I'm curious, what Cosplay did you use this prop on ?

Another good one! Thank you for the breakdown and the supplies list!

What kind of foam is this exactly?  Because I've tried googling and looking in various craft shops and only found the kind that is used for cushioning.

Hi! I'm trying to make a batgirl cowl for my cosplay, and I'm wondering if this turns out at all flexible? I'm going to need a way to get it on my head somehow. And if this isn't flexible, would I be able to make a mould of my head and cast the whole thing in plastidip? Thanks!

Where did you find foam that thick?

This is definitely going to come in handy for my GLaDOS cosplay.

Awesome thank you! Plastidip doesn't erode anything when applied directly? O.o

Excellent tutorial, this is definitely a technique to keep in mind for posterity. How durable would you say props made with this method are?

Thank you!

Hi RB! I was referred here via the Cosplay Tutorial FB page sharing your tutorial! Thanks for sharing your knowledge!

THANK YOU SO MUCH FOR SHARING! \^o^/

OMG all the things I could make now!

This will hopefully be my ah-ha moment in making the props I need!

Your prop tutorials are the best!

Can you use this on cardboard?

Very neat! Thanks for sharing~
I have the same spray paint XD

Thanks so much for the detailed how-to! I hadn't heard of the use of contact cement and wood filler for bonding foam until this tutorial--great tips.

Never even heard of plastidip before, very cool. thanks!

This is awesome, I can't wait to try this out! Thanks for sharing!

Excellent. Cosplay adventures shall continue!

This is amazing! Thanks so much

I would simply like to add, the spray on Plasti-Dip actually eats away at the foam. if you use the cans and paint it on, it solves that problem (it's something in the aerosol propellant can that reacts)

You'll get a sharper, cleaner finish if you were to do that. Over all, very nice piece. Great job.

cool thanks for the help

Awesome tutorial! (Love the name change too, btw)
I've used similar methods for making large semi-rigid props or body armor. A couple tricks I learned over time:

On the inner layers that can't/won't be seen, you can cut out portions of the center to reduce weight and increase flexibility during shaping/bonding. (This hollow space can also end up holding electronics if lighting is needed.)

Lightly score the inner side of each layer in rows perpendicular to the direction of the bend for pieces that will eventually need to be curved. This will also increase bonding strength because the glue/contact cement will "bite" into the scoring. Make the scores about 1/2 to 2/3 through each layer with a very sharp utility knife and a straight-edge.

Wow, this is really helpful! thank you, thank you.

Wow, I can see something like this being made to house portable hard drives and stuff. you could model the pieces to fit around wrists and hands like gloves or something like that.

Dreaming of a bracelet that holds small hard drives.
