In order to solve the above-mentioned problems, the present invention provides a film retaining material having voids into which cement paste can enter, on the inner surface of a formwork for molding a hardened cement product, which forms the surface that requires surface finishing of the hardened cement product. After spreading, a cement mixture is placed in the formwork, and after the cement mixture has solidified, it is removed from the mold, cured, and cured. The present invention provides a method for finishing the surface of a cured cement product, which comprises applying a coating to form a film on the surface of the cured cement product.
本発明の作用を図面を用いて説明する。 The operation of the present invention will be explained using the drawings.

される（第１図ｂ）。 When a film retaining material 2 having voids into which the cement paste can enter is spread on the inner surface of the formwork 1 (Fig. 1a), and a cement mixture is poured into the formwork,
Part of the cement paste in the cement mixture is
The cement paste enters the gap from the surface of the film retaining material 2 that is in contact with the cement mixture, and after the cement mixture solidifies, it is removed from the mold and cured to harden. Therefore, it is fixed to the surface layer of the hardened cement body 3 (FIG. 1b).
