In Uruguay, one of the most important buildings is Palacio Salvo. The present research is part of a diagnosis for the definition of an interdisciplinary project of intervention for the revalorization and conservation of its façades.

These activities started with the identification of the rock used as Kösseine Granite, of Wunsiedel, Germany. This rock is applied as polished pieces and most of them show, as deterioration features, rounding, missing parts, perforations with or without metallic inserts, often surrounded by oxide staining, deposits and soiling. Some plates eventually show up to 20 cm cracks in the edges related to splintering, chipping and two large plates are crossed by 80 cm fractures. Pieces used as steps show abrasion, rounding, and fractures in the edges causing missing parts.

Exterior and paving are among the most demanding applications of dimensional stones. Nevertheless, Kösseine Granite presents a good performance and its state of deterioration is low.
