ABSTRACT
This experimental search is based on the application of the existing rules for natural earth mortars coatings. It is checked the characterization values of natural prepared clay plasters that exist in the construction industry and verified the suitability of the regulation. To establish the application of these mortars, there are planned study strategies, to evaluate its main features and apply criteria of use. A series of tests to establish the stabilization with lime addition, values of checking mechanical resistance, adhesion degrees, humidity effects, erosion and improvements. These tests allow checking if the used normative references are applicable and detect specific cases for the application of this construction. In the experimental methodology, it is used as a reference the normative regulatory in Spain that describes the coating mortars specifications. The obtained results allow establishing more successful conditions to use this product, recommend testing methodologies and establish guidelines for testing for characterization.
