Résumé
The large-scale concrete sculpture Rygo, by artist Bathsheba Grossman, was 3D printed in 2012 using magnesia-based cement. Now privately owned, Rygo is displayed outdoors and suffering severe cracking and delamination. Due to the unique combination of an atypical cement and the 3-D printing process, there is currently no literature to draw upon concerning which conservation materials might effectively be used to slow the deterioration of the sculpture. Previous research shows that the application of a coating material could be beneficial. To determine which coating material is most compatible, samples from the sculpture that had already become disassociated from the whole were used for this research. The samples were imaged, examined under the microscope, and analyzed with x-ray fluorescence spectroscopy (XRF) and x-ray diffraction (XRD). Coatings from Evonik Protectosil and Prosoco were evaluated. Visual changes were assessed using a handheld colour spectrophotometer and glossmeter. Changes to porosity were assessed with a water drop test. Samples were evaluated before and after application of the coatings, as well as after artificial aging at the National Center for Preservation Technology and Training (NCPTT) in a QUV accelerated weathering tester for 45 days, the industry standard to represent one year of outdoor exposure. This research indicated that all silane and siloxane-based water repellant coatings were appropriate for application to magnesia cement, 3-D printed concrete structures thereby increasing the chances that Rygo will be appreciated for years to come.
