Default Styro into stone

Hey, so here is the deal.... I have carved a waterfall out of styro and I now want to make it look like rock.

I don't want to do the cement/grout thing... what are peoples opinions about other methods?

I was thinking of trying the ge silicone in grey with maybe some sand or something for texture, then possibly coloring with black silicone in some places. Would this work? has anyone done anything similar?

All help is appreciated.

That thread is amazing but I am looking to do this without using cement/concrete/grout or the like.

Any suggestions?

To be honest, I dont know if I've seen anything other than the cement-type materials that ever actually looked good.

Trying to mix sand or something with silicone ends up looking like...... silicone with sand in it. You have to keep in mind that most of the silicones are going to dry with a somewhat glossy look to them, which makes the stuff look pretty fake.

If you manage to get the sand to completely coat the silicone, then it ends up looking like a sand castle or something... not like real rocks.

but dont let me discourage you from trying to figure out something new, I just havent seen anything good yet...

Use black silicone, put it on really thick, and then cut or tear it so it has smooth faces and sharp corners.
You just made obsidian.


Part of the problem of silicone is it is translucent. So it doesn't make very good opaque rocks.
If you do try pressing in sand, use the largest grain size you can.

Instead of pressing coco or peat into silicone press gravel, pebbles, stones, slate, or other non sharp rock particles. If you find some nice flagstone (or flat sedimentary rock) you can chisel at the side and split the rock into thin veneer so its not so heavy. This is an easy way to create a creek bed, stream. I also agree the trouble of trying to make concrete/grout BG pH balanced is a chore im not interested in.

I used to be really concerned with how my BG sculpture looked when i was building it....now about a year later you can even see anything that i worked so hard to make just right. The jungle has taken over!

For my next viv i will probably spend much less effort making it look perfect without plants and more time making sure the conditions are right for healthy vigorous growth.

If its going to be moss covered, vine covered, and not visible in less than a year....dont sweat it.

I have just finished my background that has a built in "river"... now, most of it i used the grout method and then painted over that w/ acrylic paint... but i do have a piece of foam that i just painted the acrylic straight on to w/ out any grout and it looks great.... it's actually been submerged in the pond area for about 1- 2 weeks now and the paint seems to hold up fine and looks pretty natural... If you use the right color combo's you can make it look just like real rocks

only other option that I've seen that looks good is paint the foam then use marine epoxy to cover that, but it's time consuming. I have done it, and other attempts. I have not yet tried grout, but that will be next, maybe. I also may just use real rocks. They look much more like real rocks.

here is a picture of how my fake rocks turned out.




Could have looked better if i had taken more time, but being my first time doing anything like this i think it turned out well, it's just GS, covered in grout, then painted w/ acrylic craft paint.

I think it looks really good. Your painting looks good as well.

My first try at making my own rock background is still in the basement where it was long forgotten about.
