Hard coating green floral foam?

[Dustin Crops Boy]

I just sculpted something out of green floral foam - but i'd like to give it a fairly thin coat of something just so it can be sanded a tad smoother than the foam and primed/painted and made purty for casting purposes...

What's the best stuff to use that'll be easy to apply (brushed on, preferably), won't eat the foam and will be hard enough, when cured, to sanded smooth?

If you go to Michaels or Hobby Lobby and look in the foam section, they have a foam paint, comes in different colors and wont eat away at the foam. Its thick stuff and I have used it, just never tried sanding it. I still have that buck in my shop, I will try and sand it and tell you how it works.

Other than that, that foam paint is pretty great stuff.

you could try durhams water putty.

you can thin it out and apply a few coats if you want it brushable. stuff works pretty well too.

available at most hardware stores.

Smooth On has a new product for this...

It's called 'Shell Shock'

How about plaster? And yes, I know it dries pretty quick.

I use plaster or you can also give the foam a coat of vynil glue before applying any putty, to prevent solvents eat the foam.

I'd go with gesso cavas primer. Easy to brush on and is sandable once it dries. Should work fine on the foam.

5 minute epoxy won't melt the foam and it is sandable in 10 minutes. It is an excellent sealer, and it's rock hard.

There's always paper clay, light but strong, dries fairly hard and smooths up really well.

Gack - so many options I ordered some of the stuff from Smooth-On... but I'm almost done with the sculpting - so I may get impatient and buy one of the suggested options this weekend...

What about a product called "Rock-hard" or something like that? I think it's plaster based and works pretty well for stuff I've done at home.

 

[CGClone]

Wow, I didnt know there was all these options either.

Clonesix, do you use the standard 5 minute epoxy hanging on the rack at wallyworld, or a more fancy brand found at a hobby shop?

That shell shock looks awesome.

I believe gesso is a time proven method. Not that others lack anything, just that gesso has been used for years and years.

I've been trying Durhams for a number of things, and it's a great sculpting aid. If you do end up use it, be carefull with getting it too thin, it is a little fragile when thin.
