Hey guys,
I have a project coming up quick in which I need to make some large cove in the shape of an ellipse. The ceiling currently has a rectangular recess in it appx. 12' wide x 20' long x 12" deep. I have to make cove molding to go in this recess that will be an ellipse, the cove molding will be appx. 10" tall and will be painted. I'm currently thinking of using some foam insulation as build up and finishing it off with some plaster. Any better ideas? We have a CNC. The piece will be made in several sections as to get it in the room. How well would plaster stick to foam?
Thanks for the input!
