After nearly 200 years, the plaster on this large ceiling was beginning to deteriorate. Some large pieces had fallen.
Extensive staging was necessary to access the 30 foot ceiling.
Because there was so much deteriorated plaster in the large expanse of flat plaster, an economical decision was made to install a blueboard plaster system directly over the original plaster.
Blueboard plaster receives a complete coating of plaster with the blueboard acting as the “lath” or substrate. This 2-coat veneer system received a rougher base coat plaster followed by a smooth topcoat plaster.
The more ornate and curved areas of the plaster ceiling were saved by reattachment and infill with an appropriate plaster recipe and finish. Here Peter is injecting glue for reattaching the plaster to its lath.
Once glue is injected, forms are used to push the plaster in place and hold until the glue sets up. In this instance forms were screwed into place.
Curved plaster walls prior to restoration. The severely deteriorated plaster has been removed, cracks have been dug out and reattachment and infill are about to begin.
The same area following all restoration.
Another decorative area prior to restoration with the damaged plaster removed.
This area has received plaster infill following reattachment. Here Craig uses a sponge to touch up patch edges and match surface texture with original plaster.
Completed restoration to this area.
