SOLUTION: A polyurethane cement composition containing hydraulic cement, water, a polyol, and an isocyanate compound contains urea, and by adding urea to a polyol emulsion, a resin layer formed on the surface during curing is obtained. Incorporation of hydraulic cement as an element that suppresses gloss is suppressed, and a polyurethane-based cement composition in which the cured product has a high gloss surface is obtained. [Effect] The surface obtained by curing the polyurethane-based cement composition has a high gloss, high stain resistance, and can easily remove stains even under severe conditions.
