Abstract: A spray material for hot and dry spray application with improved corrosion resistance, and a hot and dry spray application method with improved corrosion resistance. A hot and dry spray application method comprises pressure-feeding a mixture comprising a refractory material and a binder, toward a spraying nozzle via a pipe, and adding water to the mixture at a distal end of the spraying nozzle to apply a spray under a hot condition. The mixture contains magnesium limestone having a particle size of 0.075 mm to less than 1 mm, in an amount of 10 mass % to 50 mass %, in 100 mass % of a total amount of the refractory material and the binder. The content of magnesium limestone having a particle size of less than 0.075 mm in 100 mass % of the total amount of the refractory material and the binder is 35 mass % or less (including 0).
