Located in remote west Texas, Fort Davis was an abandoned 19th c. Army post of adobe and stone structures when it was acquired by the National Park Service. Interior walls are lime plastered, many of which had detached from the adobe substrate after years of exposure. As a part of an open University of Vermont field school, graduate school interns were trained in injection grouting as a means of reattaching and stabilizing the plaster fragments. Some walls were limewashed and edged; some adobe walls were covered with new compensatory plasters; graffiti was selectively inpainted or filled to lessen the distraction; original paint finishes were chemically consolidated.
