PROBLEM TO BE SOLVED: To provide a method for manufacturing a decorative panel free from the deterioration of an outer presentable appearance by preventing an efflorescence or duct from adversely affecting the appearance. SOLUTION: A decorative board 2 is laid over another board 2 with a backup material sandwiched there between, in a molding frame, and a water impermeable coating material 6 is applied to the rear face of the decorative board 2. In addition, a reinforcing iron bar 9 is arranged and a concrete 10 is tempted. Thus, the decorative board 2 with a lining reinforcing concrete is prepared. When molding this liming reinforced concrete by the above method, a gasket 7 is inserted into a gap formed by holding the backup material between the decorative boards 2 laid in the molding frame 1. The gasket 7 is equipped with a first plate-like part inserted into the gap, a second flange-like part formed on the end, corresponding to the rear face side of the decorative board, of the first part and a sealing member for the gap formed on the first part. The second part is wider than the width of the gap. |
