Provided are a polyol-containing composition and a cement composition for forming a coating bed, which are capable of forming a coating floor having sufficient gloss and are excellent in workability when forming a coating film. The polyol-containing composition of the present invention is used as a cement composition for forming a coating floor for forming a coating floor on a surface to be coated by mixing with an isocyanate compound and a hydraulic cement. A coating layer-forming composition comprising a hydrophobic polyol, water, a water-soluble compound having a bifunctional or higher functional hydroxyl group, and a plasticizer having an aromatic skeleton or phosphorus atom, The molecular weight of the organic compound is less than 400, and the solubility (20 ° C.) of the water-soluble compound in water is 0.5 g / mL or more.
