I was thinking about making a background for one of my enclosures, a 120cm long glass tank. At the moment it houses my water dragon. I have a question though, I don't want to apply the background directly to the glass so I will be making one that I can put in and take out. Has anyone worked with corflute as a backing? Can expanda-foam be applied directly to corflute? Or will the chemical reaction melt the plastic? Or will it not adhere? The reason I'm thinking about using corflute is I have tons of the stuff laying around. I looked up some of the MSD sheets for popular brands of expanding foam and didn't see anywhere that recommended not using with plastic. If nobody knows I'll test it and probably post it up for anyone else who may have the same question.
