Summary:PURPOSE:To save the labor of grinding the periphery of a drain outlet on the rear face of a bathtub. CONSTITUTION:A synthetic material is applied onto a molding tool 1 by the hand layup method to form a synthetic resin layer 3, and then a force 5 provided with a smooth face 5b is mounted on a required site of said synthetic resin layer 3 before the layer is cured, and the layer is cured to form a flat face on the rear face of a molded product. Therefore, the grinding process by a grinder applied heretofore is not necessary, and the leakage prevention at a connecting section is secured in the case a drain pipe is connected with.
