Hey guys,
I need some advice from people who have used various forms of cement to build backgrounds before. I'm building a 29 gallon viv inspired by the movie Avatar. It will mimic the rainforest of Pandora, and will have a rock wall with waterfall. I constructed the background with Polyfoam from Hobby Lobby. A picture is attached. I was planning on using underlayment cement like the guy on here who built the fantastic 60 gallon viv, but underlayment cement is impossible to find. I bought some quickcrete mortar mix and tested it on a different background for another viv I'm building that isn't as special to me as the avatar tank.
The quickcrete was a nightmare! It doesn't want to stick to the polyfoam, and I had to apply it so thickly (by hand, impossible to paint on) that the original architecture of the foam was completely lost. Does anyone know what would be best to use that can be applied thinly, so that I will be able to see the shapes I carved out of the foam? I don't mind if I have to cure it with vinegar, I was already planning on that for the cement anyway, and I will be painting it with acrylic paints to seal it. Any advice is greatly appreciated!
