Abstract


The use, the manufacture, the putting into excution of gypsum plaster on old Paris façades -a marely manual technique- are specified since long ago. A number of gypsum plaster carried out under Louis the 14th reign, have still a good behaviour in spite of, as it is well known, gypsum in the outside is very sensible to dissolution. This study allows to clarify four fundamental parameters, and its conclusions make it possible to carry out rehabilitations both in prestigeous and in humble buildings: - The use of a mortar which components will be similar to those old materials; - A merely handwork. - An established proportion with a view to protect the gypsum plasters, cornices, moldings, etc. from drainage waters. - Bearing walls with higher mechanical characteristics than those of platers.
