Fake rock background with PU foam?

[Stefan-A]

Does anybody have any experiences using polyurethane foam in their fake rock backgrounds? I know some people use it both alone and as a complement to styrofoam.

Hi,

I used polyurethane foame in my terrarian. I've built it from styropor. It's a very good material. Phantastic to work with it.

I haven't used PU foam before, Stefan, but I have been thinking about trying it, to contruct a more interesting 'back wall' to my vivs. I guess it would be quite easy to 'sculpt' it to gain the desired effect.

Stefan, I have used it.
Take a look at the link.
Uromastyx - Terrarium

This are "old" pics from when a pair of Uromastyx ocellata were in it.
This is our old fireplace in the livingroom.
In a few months I will place my T. sirtalis tetrataenia in it.
The colours are different now and when it is ready I will place pics here.

That is AWESOME!!!!!

Looks great.

Does anybody have any painting tips on how to get it to look like rock? I know there are other methods, but painting seems to produce a better result.

The second thing I'd like to add to my future wall project, is lichens. Does anybody know any method of making fake ones?

About the making of lichens I cannot say anything.

The painting of the PU-foam...

When the foam was hard I started to cut rocks in it with a Stanley-knife.


I used the whole knife and not only a small part.
After lots of cuts in my hands and broken knifes I was content about the result.
Than I smeared Tile-glue (the stuff what is used to put tiles on a wall) on it.
I used a bit more water than usual so I could use a paintingbrush.
After this dried I repeated this a few times till I was content with the result.
Now I painted it with a waterbased paint that is used on walls.
When this was dry I repeated it till I was content with the result.
But to make it look like real rocks you have to do another paintjob.
I took the same paint and added a bit reddish paint so it became a bit darker. You can ofcourse use any colour.
With a brush where only a very small amount of darker paint on it I softly brushed the corners of each piece of "rock". Use only very few paint. The brush has to be allmost dry. This gives a 3D effect.

On this pic you can see what I mean how to make it look like rock.

The lizard on it is a Xenagama batilifera

The closest thing I can think of to lichens would be to use the fake spanish moss from zoo-med or maybe it's fluker's. Close second would be the stuff they sell at the hobby stores for model railroad scenery - there's lots of textures and colors and it's usually loose material that you apply with glue. I have no idea what it's made out of or if it's safe for use with critters, though. Woodland Scenics Field Grass, Flock Grass, Flowers, and Lichens

the model railroad stuff is a great idea
my brother used to work with that and even 40 years ago it looked pretty good
