A large ornament fell from the ceiling in the gallery at the Frick Collection, requiring a plaster molding ceiling repair. This is PART 2 – how we affixed the ornament back in place. See the related posts: PART 1- Ceiling repair at Frick Collection and upcoming PART 3 – How to make a plaster mold.
The pieces were delivered to the shop so they could be studied.
We ordered from a specialty sculpture store, a strong casting plaster (almost too strong and set too fast). Casting plaster is stronger than plaster of paris. When mixed with water, it hardens very quickly to be cement-like. We used wellbond to glue the smaller pieces together.
Using a Dremel tool, the backside was etched for better adhesion of the glue.
The application is finished and ready for paint. See PART 1 for painting the ornament.
