Abstract
This paper introduces and valorises pierre-simili and cimorné cladding by
confronting knowledge resulting from literature, patents and lab analysis. This
leads to original formulas and application methods, which will be further
investigated towards scientific renovation and restoration strategies.
Early 20th century architecture is characterized by the development of
innovative finishes like pierre-simili and cimorné cladding. Pierre-simili finish
or ‘stone imitation’ is used in order to imitate sandstone masonry façades. The
illusion of stone is obtained by adding lime, mica and crunched stone to a light
grey or white cement (bad mortar) and by scraping the surface to create a rough
texture. Consequently false joints are drawn into the wet mortar.
Cimorné (ciment orné) means ‘decorated cement’. Opal glass fragments are
projected into wet mortar. This technique allows applying a bright coloured
mortar that does not fade.
Currently, there is no scientific based strategy to solve present damage such
as contamination, cracks and peeling off. The combination of a literature study, a
study of records, patents and onsite research followed by laboratory analysis of
onsite lifted samples leads to formulas and application methods that will
contribute to future renovation/restoration projects.
