AN ANALITIC OVERVIEW OF PERFORMANS PROBLEMS FOR COMMERCIAL AND NON-COMMERCIAL INJECTION GROUTS AT CAPPODOCCIA REGION ROCK CUT CHURCES LIME BASED BYZANTIUM WALL PAINTINGS

Since the year 1973 the work to conserve the wall paintings in Cappadocia region has been in progress and in this process various types of commercial and noncommercial injection grouts have been used and are being used. The commercial and non-commercial injection grouts that are presently used in the conservation of wall paintings may have some disadvantages both in terms of their properties as well as performances. Injection grouts are irreversible for this reason, it is required to take care in regards to the chemical, physical properties of the grout used as well as its performance and consistency with the original material. This study aim to reveal the grouting and performans problems by means of performans analyses and tests of the injection grouts used in the conservation of wall paintings from Byzantine Era in Cappadocia region and therefore the ideal injection grouts that can be evaluate for to be used in grouting of the lime based wall paintings in the Rock Cut Churches of Ihlara Valley that have not yet been included within the scope of conservation efforts.
