Smoothing Packing Foam

darklord4 · Post by **darklord4** » Mon Oct 30, 2006 1:53 am

I am making a scratch build out of some styrofoam-like packing materials, not true styrofoam I am sure. I have used it before to make wrecked buildings for wargame terrain so the bubbled texture worked out OK as it looked like cracked wall or was covered with other things. What I'm working on now needs to be smooth and then painted. Is there any foam-friendly way to smooth it? Just trying to save my time from experimenting what works, what doesn't and what eats the foam...

Thanks in advance

Acrylic modeling material - gusso or acrylic gel or similar products. Plaster cloth might be an option, too - but you'll need to coat it with something anyway. Epoxy putty can be rolled out like pie crust (using talc or corn starch as lubricant) and draped over the form.

drywall plaster will work if your not going to be rough with it.

HobbiCo's Hobbilite filler was made for this application. I think it was invented for the RC airplane hobby, 'cos that's where you can find it. It isn't the most durable stuff, but it does produce a smooth finish on styrofoam.
