Thermal and hygroscopic characteristics of restored plasters with different surface textures

Fresco restoration includes the integration of missing plaster. Restorers use different tools and materials for the intervention. Recent research shows that restored plasters have different thermo-higrometrical behaviors at low temperature and high ambient humidity rate. Field observations of the hygroscopic behavior of different mortar textures showed that textures surfaces, with hard tools (spatula, wooden float, trowel) have harder, denser surfaces, which favor vapor condensation, while soft tooled finishes, the edge
