PURPOSE:To easily control a fading degree or the size of a spot, by mixing a plurality of resin paints up to a semi-mixed state in a mixer and subsequently spraying the resulting mixture to an object to be painted by a spray gun while holding the semi-mixed state. CONSTITUTION:Resin paints 4a, 4b having different colors receive the mixing action corresponding to the mounting number of mixing elements 11a in a mixer 11 and the semi-mixed resin paint flows out from the outlet 11b of the mixer 11. When the open degree of a confluent amount control valve 13a is controlled to a desired degree and an operating compressed air opening and closing valve 13e is opened by an operating lever 13e', an opening and closing valve 13b and a spray compressed air opening and closing valve 13d are opened, and the semi-mixed resin paint and spray compressed air are sent in a jet nozzle 13c to inject the semi-mixed resin paint to the floor surface of a bathroom from a nozzle 13. As a result, a coating surface composed of a faded spot pattern wherein the color boundaries of the different color resin paints become obscure is formed to the floor surface.
