To provide a building curing mesh sheet having excellent washing resistance, flameproof property and mechanical strengths.
This building curing mesh sheet is characterized by comprising a coarse woven or knitted fabric and flame-retardant resin coating films which cover at least the exposed outer surfaces of the fiber yarns of the base woven or knitted fabric, comprise the thermosetting reaction product of a composition, and contain a flame retarder in an amount of 10 to 50 mass % based on the coating layers. The composition comprises a polyurethane prepolymer comprising an active hydrogen-containing compound and/or an active hydrogen-containing polymer, and an isocyanate compound and/or a uretdione compound, and the flame retarder comprising a N atom-containing organic compound and/or a P atom-containing organic compound, and has a solution viscosity of 0.1 to 10 Pa×s (10 to 50 °C/0.5 to 3 hr).
