ABSTRACT
Earthen building protection could be achieved through measures involving the application both of protective products, of natural or synthetic origin, on the surface, both of plasters. The latter can be simply constituted by earth, and therefore poorly durable and requiring constant and continuous maintenance, or can be made with a mixture of sand and binder (usually air or hydraulic lime, and sometimes even cement). This second type of plasters, especially when the cement is used as binder, has different deformation characteristics compared to the surface where has been applied, so to compromise the adhesion to it. Moreover, it also make it difficult to understand the real material consistency of the earthen structure.
