Gypsum plaster is often a character-defining material of historic interior spaces. However, plaster is also vulnerable to loss, and historic finishes can be damaged by water infiltration or inappropriate modifications to building structures or mechanical systems.

Part 1 includes corrective measures to interior plaster finishes within the law library of the Nebraska State Capitol.
