PROBLEM TO BE SOLVED: To facilitate the visual confirmation of residual bubbles in defoaming work by coloring an intermediate layer. SOLUTION: A method for producing an FRP molding by spray-up molding comprises a process in which a gel coat is sprayed and cured to form a gel coat layer 1, a process in which the mixture of relatively short fibers 21, a thermosetting resin, and a coloring agent 23 is sprayed to form an intermediate layer 2, a process in which the mixture of relatively long fibers 31 and the thermosetting resin is sprayed before the intermediate layer 2 being cured to form a reinforcement layer 3, and a process in which the intermediate layer 2 and the reinforcement layer 3 are cured. |
