PURPOSE:To improve water proof, dust proof and antioxidation properties of a paint coating for outdoor stacks such as coal by sprinkling a predetermined amount of the total paint amount to be sprinkled from the upper side of the stack and the residual amount from the lower side. CONSTITUTION:When an outdoor stack such as coal is covered with a coating paint which becomes insoluble after dried, the total amount of the paint is determined from the surface area and coating thickness of the stack to sprinkle 50-75% of the paint from the upper portion side of the outdoor stack through a nozzle. At the remaining paint is sprinkled with the nozzle directed obliquely upward or horizontally while moving around the bottom of the stack. Thus, a continuous coating is satisfactorily formed to improve water proof, dust proof and antioxidation properties of the stack. |
