The open pore of stone cultural heritage is not expected to have an effect only by consolidation, and it has a drawback that only the internal wall adheres and gets consolidated due to the incrase of liquidity caused by the low viscosity and difference of materials in the case of filling with high molecules synthetic resins. Therefore, this research selected the effective filler for Three-storied Stone Pagoda at the West of Gameunsaji Site through the verification of filling effects of materials using the information about various fillers based on minerals. As the result of filler experiment, got filled with the combination of KSE 500 STE + KSE Filler A․KSE Filler B that is the same as the Member or has very similar properties. The total surface area of the west stone is 252.6㎡ and the area where the internal opening has been developed is 17.77㎡(7.03%) requiring a task that fills the internal(24,885㎖).
