Polystyrene Foam- Terrain?

[Deleted]

I just bought a small block of polystyrene foam and I'm wondering if it will make good terrain.

I couldn't find any of the pink insulation foam that GW seems to like, so I thought this would make a good substitute.

However, it seems very soft, so I'm wondering if the paint will stiffen it up a bit or if I wasted $5.

I would still go to Home Depot or Lowes and get the pink foam. Fair warning; it comes in 4x8 foot sheets. So take a pick-up truck to get it.

I've used it, it works pretty good, I suggest getting a bit of plaster crack filler as well and some primer in a bucket, primer the whole thing by hand before you start to use anything that comes from a spray can because it will melt the polystyrene.

Insulation foam is a good choice too. You're looking for high density foam used for isulating between ceiling joists.

Insulation foam is much better, but if you want to work with polysterene foam, its best to 'seal' it somehow. Plaster spackle is a good way as is prushing on some glue. If you are looking to prime it, use primer from a bucket or a LATEX based spray primer. Krylon makes one. The problem with this foam is durability. Really, if you can afford it, just get pink insulation foam.

Thanks, guys. I'll borrow my step-dad's truck and go to Lowe's to get a chunk.

I've always ussed polystyrene. And I never had to seal it. But I did use just acrylic spray paints for undecoating.
It works very nice though.
