Foam treatment

[dcfxq]

Just wondering if any one has tried using FoamPrep as a "sealing coat" on their layout. This is a glue-like product that is sold at all the shows in the mid-Atlantic region along with a hot wire form shaping tool.

What do you use on foam surfaces as a finish coat?

I use ordinary, appropriately colored, latex wall paint.

I use about 3 coats of latex paint - underbrush brown to seal the styrofoam. I've seen some people seal it with a couple of coats of diluted white glue, but I think it makes it too hard.

I use styrofoam for the base. To extend the carved styrofoam into the styrofoam base so as to provide a smooth transition, I apply spachling compound and then "wet sand" it when dry.

Instead of a hot-wire, I use a butcher's carving knife (actually a de-boning knife) to care the styrofoam.

i use foam then cover it with WS plaster cloth. After that, paint if brown with a laytex paint.
