I have a 1927 tudor style home that has plaster crown molding in several rooms. One area has some damage from a previous water leak. (see attached photos)
The plaster is large and most likely made with a form. Is there a way to repair this plaster, or do I need to remove the plaster crown for the entire room, and install new crown molding?
I took measurements and have started to create a profile, so I can make a form (possibly out of wood) that matches the crown molding. The thought was to chip away all the loose plaster and use the form to mold some new plaster in place. My concern is - will the new plaster adhere to the old, or will the weight of it make it fall to the floor over time?
