Sir John A. Macdonald Building Restoration

Built in 1930 with a Beaux Art design, the Sir John A. Macdonald is undergoing a significant multi-phased rehabilitation project. Historic Plaster Conservation Services (HPCS) was asked to take on the challenge of cleaning the oily soiling off of the very delicate paint on the ceiling of the Main Hall. To do the job, HPCS introduced its new product TRI Funori, a natural, non-toxic polysaccharide extracted from Japanese seaweed. As a cleaning agent, TRI Funori is used with washi (Japanese rice paper). The washi is held in place and the TRI Funori liquid is gently brushed through it onto the soiled surface. After an appropriate dwell time (i.e. 5 minutes), the washi is removed, leaving a cleaned surface, with no paint coming off. The TRI Funori worked like a charm.
