Just applied 1 1/2″ styrofoam insulation to a concrete foundation wall. I need to parge over it from the grade line up to the start of the siding. I am wondering what is the best way to apply a stucco wire over it? Can I apply the wire with some type of fastener thru the foam board and into the concrete… I was thinking of using some 1/2″ treated plywood over the foam and screwing thru the ply and the foam into the concrete then I could wire and parge over the ply…Any experiences or suggestions here sure would be appreciated.
