PROBLEM TO BE SOLVED: To allow removing by washing when released from a mold after steam curing by laminating an adhesive layer made of a specific emulsion type acrylic adhesive, a specific synthetic rubber and a specific concrete curing retarder on one surface of a synthetic resin sheet. SOLUTION: A tape obtained by laminating an adhesive layer made of 100 pts.wt. of an emulsion type acrylic adhesive, 5 to 50 pts.wt. of a synthetic rubber and 0.5 to 20 pts.wt. of a concrete curing retarder on one surface of a synthetic resin sheet is manufactured. The tape is laminated on surfaces of tiles aligned in a matrix state so that an adhesive is brought into contact with the surface. Thereafter, a concrete composition is placed in a form, and cured, and the concrete is hardened. Then, curing of the composition leaked from joint parts of the tiles, crept and adhered to the surfaces of the tiles is retarded. Thus, the composition can be completely removed only by washing with a water flow.
