Call for help - foam backgrounds
 
http://lh3.ggpht.com/_5F4NBVnXM50/TJ...OSw/s800/v.png > I was wondering if anyone could give me advice on building an expanding foam background. I have a new viv and would really like a nice background. I need to know what products to use, how long it will last, and any other info would be appreciated.

You have two options in terms of foam, expanded polystyrene (styrofoam) or expanding polyurethane foam. I have used both over the years with a range of amphibians. the type I used was exterior grade polyurethane foam from one of the big sheds (Homebase or B&Q). I've also seen some very attractive backgrounds made with both of these materials, but I've never personally made a complete background with either myself.
Compared with natural materials they have one potential problem as far as dartfrogs are concerned, they do no retain moisture, so humidity in the vivarium may drop depending on the substrate and how often you spray.
The advantage of polystyrene is that it is easy to cut and shape. With expanding polyurethane foam you have two options - either create a background by spraying the foam onto some sort of support then fit it in the viv, or spray the foam directly onto the viv. You have to be brave to do this as it's not easy to control, and once it's there, it's there for good. The most important thing about expanding polyurethane foam is that it must be allowed to cure completely before you try to do anything to it or put animals anywhere near it. Depending on how thick the foam is, they can take anything from days to weeks, so you need patience. Personally, I think there are easier options.

I think you have been misguided on how expanding foam (great stuff) works. Great stuff can cure to a usable form in just hours. As soon as you apply it the clock starts ticking. You can play with it and form and shape it at different levels of it hardening. Once it hardens you can carve it, coat it, paint it, and let your imagination run wild. Here is a current thread of mine where I use painted Great stuff. http://www.dendroboard.com/forum/par...thing-new.html

If you look at the date and times, this was all done in about 24 hours.
