PROBLEM TO BE SOLVED: To provide such a curing sheet for molding hydration hardened material including concrete as being capable of saving the waste of limited resorce, simply forming a rough pattern on the surface, protecting the unhardened surface and maintaining its shape. SOLUTION: A curing sheet for hydration hardened material has a moisture permeable resin foam layer 2, preferably of water emulsion resin, formed on the surface of a moisture permeable base material sheet 1 of paper or woven cloth. Specially, a rough pattern is provided on the surface of the moisture permeable resin foam layer 2 so that a design of the rough pattern can be granted to the surface of the hydration hardened material. A moisture permeable protecting layer can be provided on the surface thereof. |
