Painting stone

Hi guys, I've just finished carving a great stone pattern into some polystyrene (with my foam engraver) and I want the paint job to be top notch to bring out the work I put into the stone carving, and not make it look drab and flat. I covered another set wall with plaster, but its hard to use, I only have 5 or 10 mins to cover it with the stuff and it ends up a bit messy. The plaster fills up the cracks a bit in one or two places and the stone work gets lost. Strings of plaster dry between stones, it dosen't have the look I want. I may have to get some better plaster, but its fine casting so should be ok. Probably just me, but all the detail is hard to cover in less than 10 mins. I love using it for less detailed set pieces like stone floors or plain walls, but for the detail in the stone-work, its hard to get the plaster cover the stone-work evenly. Any tips? Maybe I should just paint straight onto the styrene? The only problem is that its not an even surface to paint. I would prefer to use plaster, but I'm having trouble with it. But, the main question I'm asking is, what would be the best way to paint a stone colour on the set-piece? Start with a base coat of black and then darkish grey? Or should I dry-brush or something? I have done some nice painting, but its too flat and I need it to have more depth and be more graphic. Any help would be greatly appreciated!

a good stony texture can be made by laying it flat coating the whole thing with pva and sprinkling sand on top,let it dry and pour off the excess. as for painting this is how i and i think most, would approach it, paint it in a mid tone let that dry and then apply a dirty wash of a darker tone, so it runs into all the cracks and detail. when the wash has dried drybrush the whole thing with the lightest tone, works for me, good luck.

Hey Seamus, Actually, using worse-quality plaster is the way to go! I buy spackling plaster/drywall putty - not sure what it's called there, it's like plaster but sold premixed in tubs, it air-dries. It might crack a little bit more but it's easy to patch. It takes longer to dry, and is very easy to work with - you can control thickness quite well, and it's easy to add texture to. You can also mix pigment into it before applying it, mind it'll generally look more muted once it dries. But it's good for creating a base stone colour. Then, as amoebaboy said, painting in washes and drybrushing really brings out the texture.

my rocks that I make I start with flat black base coat then drybrush 7 layers of progressing lighter colors, sometimes I mix grays, browns, and reds. Then in the end I add some grass texture.

I know its not what your asking, but if it helps, I made these two big polestyrene hills a while ago, just for the background. They're almost flat, but curved on the top to create depth. What I used for these was just paper mache. I know its very un-technical, but it worked a dream. Maybe if you wanted your wall to be bumpy you could use this technique. If you like I'll get a picture! Fish PS I'll send your bookshelf off tommorrow!
