"Care And Repair" Maintenance And Reparation Of Plastered Facades With Special Focus On Istrian Dwellings

This paper investigates the traditional techniques of plastered facades in Istria. It begins with an introduction emphasizing the importance of preserving the architectural heritage of Istria amidst the accelerating decay. The discussion then delves into restoration theory, including insights from John Ruskin on restoration principles and guidelines provided by ICOMOS charters and other evocated in the topic of authenticity, craftsman and traditional techniques. A case study examines 19th-century plaster surfaces in Istria, distinguishing between plane plaster surfaces characteristic of villages and decorative plaster surfaces found in town buildings. Drawing upon theoretical and practical knowledge acquired from workshops in “Kartause Mauerbach”, the case study presents traditional plaster techniques alongside photos and sketches from the workshops. Key aspects explored include traditional materials, render mixtures, tools, and equipment, as well as common mistakes in plaster application. Maintenance principles are outlined to guide effective preservation efforts, and potential areas for future research are discussed. Through this examination, the paper aims to present traditional plaster techniques and their application in repairing and protecting Istrian plastered surfaces. By providing practical guidance informed by theoretical understanding, the paper contributes to the ongoing preservation of Istrian architectural heritage.
