The face of the Seated Stone Buddha Korean Treasure No.84 of Sinboksa Templesite in Gangneung was contaminated with a glossy resin, spoiling its beauty. The contaminants covered the face, the forehead of the urna, to the bottom of the jaw. FT-IR analysis on a sample of the contaminants identified the substance as cyanoacrylate instant adhesive, which can normally be melted with acetone and removed with a swab. However, given that the surface of the statue was severely weathered from prolonged open-air exposure, alternative removal procedures were considered, to minimize the possibility of physical damage. After research, two removal procedures were utilized: one procedure involving poultices, which had been used to remove graffiti from the Samjeondobi Stele, and one procedure involving steam sterilization, which has been used to remove resin from pottery and porcelain. When both the poultices and steam sterilization were applied together, the resin was removed within twenty-four hours, without physical work using a swab.
