This study aimed to identify the properties of infill materials suitable for the structural reinforcement of the earthen wall supporting the mural in the Josadang Shrine of Buseoksa Temple, using materials closely resembling those of the original wall fabric. It also aimed to establish optimal mixing ratios that ensure structural stability and visual compatibility. Soil comparable to the original earthen wall was selected, and test specimens were prepared by incorporating fibers (straw and hemp) together with binders, Dobak (a seaweed-based adhesive), hydroxypropyl cellulose (HPC), and rice starch paste. The specimens were subsequently evaluated for surface condition, colorimetric properties, volume and weight changes due to drying shrinkage, and mechanical performance, including compressive strength. Results indicated that fiber inclusion effectively suppressed drying shrinkage and enhanced overall stability of the structural and finishing layers. For the structural layer, mixtures containing straw or hemp fibers combined with 1.5 %–3 % HPC or Dobak exhibited superior crack resistance, surface stability, and mechanical strength. For the finishing layer, compositions incorporating hemp fiber with 1.5 % Dobak or HPC proved most appropriate. Specimens with 3 % binder, however, displayed surface staining and pronounced color differences, underscoring the necessity of careful binder selection for each application. These findings emphasize the importance of layer-specific mixing ratios in multilayered conservation systems. The study provides a scientific foundation for the long-term preservation of traditional murals and offers essential data for developing practical infill materials in conservation practice.
