I have previously had great success in building fake sandstone/rock walls using acrylic render and expandafoam, and wanted to look into trying a similar thing for a fake limestone effect. Again, I would be using expandafoam, but I would be looking for a much smoother coating for it to simulate the look and feel of a limestone cave. I've done a bit of a search, and come up trumps, so I thought I'd throw the question out to the DIY masses. Has anyone tried this before with any success? If so, care to share your secrets?
