Stone, Earth, Cement, & Coatings: Preserving & Repairing Multi-Material Masonry Systems



Canceled: Due to COVID-19, this course has been canceled, but will likely be offered in 2021.

This workshop is offered in partnership with the Vanishing Treasures Program. Using the Frijole Ranch and Pinery in Guadalupe Mountains National Park as field sites and laboratories, this workshop will focus on preservation challenges for multi-material masonry resources that have a legacy of incompatible treatments.

Students will have an opportunity to work with a non-standard masonry system composed of limestone, earthen mortars, and limewash that has seen Portland cement and latex repairs. Working both in the classroom and the field, trainees will have considerable hands-on opportunities to experiment with techniques for the careful removal of latex paints, assess options when treating structures with Portland cement repairs, repoint with earthen mortars, and explore when to use lime-based finishes with earthen masonry components.
