Hey Sumo, I know Krylon paints do. Are you trying to texture foam by spraying it? Marc Visit:

yeah, its for texturing. Do u think that would work for like a brick wall or something of rough rocky surface? Just like give it a couple sprays and let the paint do the rest?

It's been a long time but I think model glue will do it also.

Hey Sumo, Yes it should work well for that. I would just test it out on a small piece before doing anything perminent. Marc Visit:

Sumosanta: Another thing that eats away foam is Acetone. You can get some real interesting textures with it. Experiment with it and be careful. Dan

Hey that's a pretty sweet idea for making brick walls. I made one once by spreading some Durham's Water Putty onto a piece of cardboard and then pressing the edge of a piece of lathboard into it repeatedly. I used the end of the lathboard for the short vertical grooves. That Durham's is some great stuff. You can pick it up at pretty much any hardware store and it mixes with watwer just like plaster, but it's a lot stronger and more flexible. They say it's actually plastic, and it does seem to be. Or sort of like a lightweight, plastic-y plaster substitute. It's a lot easier to work with too. Last night I built a forge from a few pieces of styrofoam glued together with carpenter's glue with a strip of burlap glued around the outside to give grip for the putty, then I mixed up a really thick batch of putty and troweled it on. When it was drying I could smooth it down or texture however I wanted, and then in about an hour when it was dry I drew on some lines for stone joints and cut them with the edge of a needle file. A little weathering with some paint washes and some charcoal rubbed on and then I wiped the whole thing down with a paper towel slightly damp with paint thinner, and I have what looks like a multi-ton stone forge. And it's nice and light too.

A couple things I should add: That brick wall I made on a piece of cardboard ended up warping. I should have used foamcore board or plywood. But if I lay it flat and tape the edges down onto a board it works fine, and it's a lot lighter and easier to store this way. And the forge I made, I never siad this, but it's a miniature. I just read what I wrote and it sounded like I made a full-sized one or something! :o

It's pretty nasty stuff! You definitely want to have good ventilation and wear gloves.
