From Angkor to Zanzibar and Venice to New Orleans, soluble salts are responsible for causing significant damage to porous building materials. But how does salt weathering take place, and what level of salts are harmful? Are certain salts more damaging than others? Should they be removed and if so, how?
The use of poultice treatments is well established in conservation, however the complexities of salt migration within historic structures have produced variable and unpredictable results. Poultice Desalination of Porous Building Materials presents new applied research on the process of poultice desalination through practical applications for conservators and others whose job is to assess, treat, and evaluate the impact of salts on porous building materials.
Designed for field-based conservation professionals, this hands-on workshop will be conducted through a combination of pre-workshop reading assignments and workshop lectures, demonstrations, and field trials. It will provide participants with a solid foundation for the poultice treatment of salt-laden building materials.
Topics to be addressed include:
- Guidelines for poultice desalination
- Building pathology understanding the building construction context for moisture and salt related damage
- A review of the behavior of porous building materials
- Salt and moisture transport through porous building materials
- Introduction to salts and salt weathering
- Working principles of poultice systems: optimizing salt removal
- Criteria for poultice selection: modifying your poultice to match your substrate
- Practical pre- and post- poultice treatment investigation and assessment methods
- The limits of poultice desalination
The Poultice Desalination of Porous Building Materials workshop is organized by the GCI Education Department as part of its Science Workshop Series: Research into Practice, which aims to disseminate the results of important research to the conservation field. This workshop is a result of research conducted through the GCI Science project, Desalination of Porous Building Materials.
