Help with foam

Post by Mars - 1 »

I'm getting ready to start a project using foam for the basic shape. What do I coat the foam with for a base for adding details and painting?

When you say foam, do you mean that you are using blue foam blocks that you've carved, or foam core board cut and glued to form shapes?

If you're talking styrofoam, like the pink or blue insulation or the white packing blocks, I use three things.

1. Hot wire cutter
2.. Old, fine toothed razor saw
3. Olfa straight blade, "snap off" knife. I can extend it out as long as necessary to carry planes across areas I need.

Most fine sculpting, though, I do with files, some custom sanding blocks and X-Actos.

Then it's time for Aves. :)

If you have any troubles getting the Aves to stick to the foam...try a thin coating of 5 min. epoxy....let it cure...then apply the Aves.
Helps the putty stay in place real well.

Wouldn't it just be easier to cover it with Sheet Styrene (unless the shape was curved or spherical?)

A layer of general epoxy, or West Systems epoxy and fiberglass.

5-45 minute epoxy is a bit fast... :wink:

Depending on the foam... is this foam insulation pink foam? If so- the epoxy will melt it down, just like spray paint would. There you need wood glue, then resin. If it is hard urethane foam, then coat with epoxy and resin.
