View Full Version : Sealer On Craft Foam

08-22-2009, 05:21 PM

So I'm creating a prop for a cosplay photo shoot for my fiancee and my friend, specifically, a scaled down version of the Lance of Longinus from Neon Genesis Evangelion. (Reference pics attached.)

To create the spiraled look of the end of the pole, I wrapped and overlapped a broomstick with several long strips of craft foam, which came out looking good. I coated it with Mod Podge, which helped bond the foam to the broomstick. The thing is, craft foam soaks up Mod Podge and isn't left with a hard finish once it dries.

Can anyone suggest a sealer or any other substance than can render craft foam harder, you know, more plastic-ish. Normally, I'd just coat the whole thing in epoxy resin, but the girls want to do the shoot tomorrow and therefore can't wait the 72 hours it would take to fully cure and dry.

Any suggestions?

Bondo maybe? It dries much quicker than 72 hours.

my only suggestion would be to coat it in resin I did that for the inside pieces of my gauntlets it takes a little while to dry (hours) and can end a bit tacky becausei ts foam but it does harden up then you can just prime it and paint it w/ out worrying about the foam soaking the paint once you prime It and it drys its good to go

Try multiple light coats of elmers glue under a fan on high. Lightly scuff when ready for paint. Looks nice, too. Thanks for sharing.

Wallpaper paste works pretty well too.

modge podge with a base layer of white glue also works, and it gives it a nice gloss in the end.

If you are patient, you can use several layers of clear enamel spray paint. Spray it, run a fan over it, wait 20 minutes add another layer apply as needed.

I agree with Kakerano. Mod Podge works beautifully and each layer dries in about 15 minutes.
