I figured I would start another thread to continue this since the other one was getting a bit pic heavy. Anyone that wants to read it start to finish here's the other thread: http://www.herpcenter.com/general-construction/21569-making-new-home-skif.html So to recap: Liz and Mala came over a couple of weeks ago to help me work on the layout and getting the great stuff in place. I also built a pond out of GreatStuff that night as well. Last weekend I went ahead and worked on painting it. I coated the whole thing in black acrylic paint and then added gray on top and added mossy green like accents on top. I still need to cover it with fiberglass, maybe I will do that sometime this weekend. So tonight I decided it was time to stop procrastinating and start working on the "fun" part (yes that was said sarcastically). I started painting the cave area with black. And Liz, I can tell you I was cursing your name the whole time I was working on this! (It was her idea to add the cave in with Styrofoam) The acrylic paint doesn't really want to stick to the GreatStuff, but I can get it covered pretty well and then when I go back for a second coat that usually will cover the "holes". So here is the whole thing with the black coating on it. I will work on adding rock colors tomorrow or sometime over the weekend. Now, I also found out that I have a little problem with the GreatStuff and the tiles. It seems that the GS is pulling the tiles off the wall. I ended up using some screws to close up most of the gaps and will be covering all the seams with silicone.
