PURPOSE: A manufacturing method of FRP sculpture is provided to perform quickly a sanding process of FRP sculpture by using a machine. CONSTITUTION: A manufacturing method of FRP sculpture comprises following steps. A mold frame of sculpture is completed by using one selected from styrofoam, timber and clay (S110). An FRP mold is completed by using a mixture of formica, mat, talc and hardener after release agents are applied to the surface of the completed mold frame (S120). The FRP mold and the mold frame are separated after the FRP mold is cured (S130). A FRP sculpture body is completed by mixing formica, mat, talc and hardener in the inner surface of the separated FRP mold after the inner surface of the separated FRP mold is applied with release agents (S140). After the FRP sculpture body is cured, the cured FRP sculpture body is separated from the FRP mold (S150). Paraffin wax which is coated on the outer surface of the separated FRP sculpture body is removed (S160). The coated paraffin wax is removed with sanding (trim) by using a pressure jetting machine in which at least one material among sand, iron powder and stone dust is filled (S170). When the filled material is sprayed, a sanding gap between an air gun equipped in the pressure jetting machine and the outer surface and of the FRP sculpture is adjusted and the filled material is sprayed with a discharge pressure of 13-17 kg/cm^2.
