PROBLEM TO BE SOLVED: To provide coating mortar which allows thin coating to thick coating and satisfies trowel workability, adhesion, smoothness and flexural rigidity though conventional coating mortar does not satisfy the demands.SOLUTION: The coating mortar includes: (A) 100 pts.mass of cement; (B) 80-103 pts.mass of fine aggregate; (C) 0.09-0.20 pt.mass of a water retention agent; (D) 0.22-0.36 pt.mass of a water repellent; (E) 0.14-0.43 pt.mass of fibers; and (F) 2.4-4.1 pts.mass, in terms of total solid contents, of (F1) a surface hydrophilic polymer and (F2) a surface hydrophobic polymer. The content ratio (F2/F1) of (F1) the surface hydrophilic polymer to (F2) the surface hydrophobic polymer is 0.18-0.43. |
