PURPOSE:To applicate a washing efficiently in a short period without scattering of the washing to contaminate the human body and environment by covering the casting mold with a covering with a clearance in between which is filled with the washing. CONSTITUTION:The covering 3 is first put over an entire surface of the casing mold 1 so that a clearance 2 with an appropriate thickness separates the covering from the molding. Then, the clearance 2 is filled with the washing 5 such as pasty or slurry-like liquid. The clearance 2 has at least two openings to the outside so that the washing 5 is smoothly introduced in the clearance 2 by expelling the air in the clearance. The covering 3 is, for example, folded along the entire periphery except the said openings so that the edge of the folded covering has a close contact with the mold frame 4 or the casing mold 1 to prevent the filled washing 5 from leaking. Surplus washing of that filled in the clearance 2 is removed by a vacuum pump or tilting the mold to allow the surplus washing to flow out of the clearance 2.
