Abstract

In this study, a preliminary verification of materials and application technologies such as wall reinforcement and stabilization of the colored layer was conducted along with a preliminary investigation on the current status of damage for the conservation treatment of <Shide>, a earthen wall painting of a temple during the Joseon Dynasty, and the results of the conservation treatment were presented based on this. As a result of the investigation for the selection of the target mural's damage status, wall structure, past conservation treatment methods and materials, and conservation treatment materials, it was confirmed that the physical properties of the filling agent made by mixing gambling glue and glue were suitable for conservation treatment in the filling agent experiment. In the colored layer fixing agent experiment, 1% of glue, 2%, 0.1%, 0.3%, 0.5% of MC. aqueous solution and 2% of MC. aqueous solution (weight ratio 1:1) were mixed with the adhesive agent used to reinforce the damaged part of the wall and support the bonded side, and the filling agent was applied by mixing gambling glue and glue and separating the layer of the wall, and the crack area was reinforced with a filling agent mixed with soil fragments recovered from the wall. 1% and 2% of glue with the least chromatic change were applied to the color layer reinforcement treatment, and 0.3% and 0.5% of MC. aqueous solution were used for wall screen facing, but it was wet-washed with distilled water to prevent any pacing residue. The fixing treatment for the peeling part of the colored layer with a thick thickness was settled after injecting 2% of glue and 2% of MC. aqueous solution with a syringe. As a result of the conservation treatment, bonding and restoration of 138 fragments that fell off the wall were completed, and the stability of the fixing agent was verified by comparing the chromaticity before and after the reinforcement treatment of the colored layer. By applying the material selected through scientific verification to the conservation treatment, more effective conservation treatment could be performed.
