|I have saved up a good bit of styrofoam packing and had seen how to make large Boulder Rocks out of styrofoam and cannot find the site.
It was a good youtube instruction. Anybody know of a good youtube that shows how to make large boulders out of styrofoam?

|It should be a simple process, the same as when we make styrofoam troughs that need to weather outside the entire year for many years:|
1. Shape your styroboulder
2. Use a heat gun to melt and fuse the styrofoam "balls" together and make the surface firm and paintable.
3. Paint as desired with a weather durable paint. Use a flat sheen, as opposed to glossy.

|Thank you. Did you put some type of concrete or use another medium for the gritty stone look?|

|Nothing is added. The styrofoam is "carved" with knife, cement trowel, wire brush or whatever you like. I prefer a corner paint scraper, and a wire brush for final surfacing. I usually try to accentuate the depressions by blending darker colors in them. You will find that the heat gun will also create interesting textures. You might want to practice on a plain styrofoam piece first.|

|We get interesting animal statues made from some sort of foam then painted over. They don't last too long out of doors. Wouldn't the foam break down even if painted?|

|Mary I do not know what kind of foam the statues are made of but....if something is real styrofoam this stuff will not break down for a million year.|
Maybe it is the vegetable based degradable foam. That is suppose to dissolve if it gets wet.

|@cinta I didn't know there were different kinds. I will goggle around and see what I can find. Thanks|

The "biodegradable" packing foam/foam peanuts are just extruded corn starch puffs. They're basically Cheetos without the "cheese" dust.
