I'm doing quite a bit of work for a local hospital and have recently taken on an Acrovyn wall covering project. I have checked several different web sites, one provided by the manufacturer as well as Utube etc. I can't find a method that I find acceptable, quality wise for cutting the manufacturer provided trim pieces. I've tried simply using a utility knife, various snips, a sharp manual miter box. Nothing seems to give me what I consider a really clean accurate cut. Any ideas? Again I'm working in a hospital so sound volume is a critical factor.
