PROBLEM TO BE SOLVED: To provide an apparatus for supplying a coating which controls the deterioration of the coating associated with the interruption of the supply of the coating and can supply the coating to a coating gun by a tank pressurization method. SOLUTION: A coating circulating passage 11 fitted with an air pump 13 which is actuated at the stop of coating is connected to the coating discharge opening and coating return port 10b of a coating supply tank 10 for supplying coating by pressurizing air during coating. The air pump 13 is connected with a bypath 14 through three-way valves 16, 16a which are opened to bypass the pump 13 during coating. A coating gun 3 is connected to the passage 11 on the downstream side of the bypath 14, and a two-way valve 18 which opens the passage 11 when coating is stopped is installed in the passage 11 downstream from the coating gun 3.
