ABSTRACT Sacrificial protection is a kind of active preventive intervention to conserve authentic fabric of architectural heritage, especially surfaces. This paper summarises briefly the term of sacrificial protection and technical options. It has been discussed that sacrificial plasters, shelter coating and plastic repair or repointing are three proven sacrificial protection measurements to conserve architectural surfaces. Two case studies show the preliminary approaches with help of sacrificial protection concept to restore historic fair faced brick façades in China. Sacrificial protection concept did not originate from Chinese conservation practices, but it provides new prospects for sustainable conservation and revitalisation of architectural heritage. The implementation of sacrificial protection is still limited and more scientific studies are needed although most of approaches are traditional.
