Characterisation of old azulejos setting mortars: A contribution to the conservation of this type of coatings

摘要

One of the most typical Portuguese facades' coatings is the glazed tile (azulejo) wall coating. Azulejos are in Portuguese history for six centuries, being considered a historical heritage and a mark of Portuguese culture. The setting mortar used in the azulejos application plays an important role for the correct functioning of the entire coating system. Therefore, for correct conservation its study and well detailed characterisation are fundamental.
