である。 The film forming material is made of an organic polymer composition that can be melted by heating to form a film covering the surface of the hardened cement body, and has a shape that has voids into which the cement paste in the cement mixture can enter. If so, there are no particular restrictions, but materials with a high melting temperature require high heating temperatures, which can have an adverse effect on the hardened cement such as cracking and deterioration due to temperature rise, so materials with a low melting temperature are recommended. Desirably, polyethylene, polypropylene, etc. are suitable, and a mixture of these may be used. In addition, the shape can be woven fabric, non-woven fabric, artificial leather, synthetic leather, foam having open cells (so-called sponge structure), etc., but woven fabric, non-woven fabric, artificial leather,
Synthetic leather is suitable because it is easy to obtain and handle.

る。 When spreading the film-forming material onto the formwork, if it is being spread on the bottom surface, it is sufficient to simply place it on the bottom surface, and apply appropriate moisture to the surface of the formwork or the surface where the film-forming material is spread onto the formwork. It can be pasted by If it is necessary to spread it to the side of the formwork or to the bottom of the formwork with a certain degree of strength, it can be adhered with adhesive. The adhesive to be used is one that melts together with the film-forming material when heated and solidified after cooling. For example, an aqueous solution of polyvinyl alcohol, which has a low melting temperature and does not carbonize when heated, is suitable.

法。[Scope of Claims] 1. A coating made of a thermoplastic organic polymer composition and 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 of the hardened cement product that requires surface finishing. The film exposed on the surface of the hardened cement body after spreading the forming material and pouring the cement mixture into the mold, and after the cement mixture has solidified, is removed from the mold and cured to harden. A method for finishing the surface of a hardened cement body, which comprises heating and melting a forming material and then cooling and solidifying it to form a film on the surface of the hardened cement body. 2. The method for finishing the surface of a cured cement body according to claim 1, wherein the film-forming material is a woven fabric, a non-woven fabric, artificial leather, or synthetic leather.
