We live in an older house (for southern California) with plaster interiors. We’re re-modeling and adding on, and I want to keep plaster interiors. My builder says his subs won’t do three-coat plaster any more because it can’t have the asbestos fibers in it to hold it together, but will substitute plaster over buttonboard, which he says will look, feel, and sound the same.
Is he corrrect? Has three coat plaster gone the way of the dinosaurs? Is plaster over buttonboard comparable?
