Terranova, a popular pierre-simili cladding Strategies and techniques for restoration


Abstract eng:
At the beginning of the 20th century, the application of innovative finishes on façades became a popular phenomenon in Belgium. Decorative plasters were frequently used to hide the aesthetically imperfect structure and to imitate the (sand) stone aspect. In order to create an appearance of sand stone, ingredients such as lime, mica and crushed stone were added to white cement. Afterwards, the surface was scratched or scraped to shape a rough texture. As a result a typical ‘pierre-simili’ or ‘stone imitation’ was obtained. To create a convincing sand stone masonry imitation, simulated joints were drawn into the wet plaster (Verdonck and Dekeyser 2010). Today, these pierre-simili finishes suffer in most cases from discoloration, cracks, peeling off and other damage which has completely changed the initial perception. Since there is lack of knowledge about the composition, properties and application of these plasters within the restoration/conservation issues, many questions remain unanswered. As a consequence, incorrect decisions are often made during restorations, resulting in increasing damage. A remarkable example of pierre-simili plaster is Terranova. This particular type is the focus of the research. By means of damage assessment, literature studies, the study of historical patents, laboratory analysis of representative samples and a comparative research between similar claddings, this research proposes legitimate solutions to revitalize the Terranova finishes. Original formulas and guidelines for stone imitating plasters will contribute to sustainable restoration projects.
