A dual component mixing system for coating comprises a first tank containing a main agent, a second tank containing a hardening agent diluted with thinner, a mixer which mixes the main agent and the hardening agent and supplies the mixture to a manually operated coating gun, a main agent line connecting the mixer and the first tank, a hardening agent line connecting the mixer and the second tank, a flow meter disposed within the main agent line, a flow meter and a flow regulating valve disposed within the hardening agent line, and a feedback control device which receives signals from the flow meters and controls the flow regulating valve so that the amount of hardening agent is a predetermined ratio with respect to the amount of main agent. The dual component mixing system according to the present invention provides an adequate control of the main agent/hardening agent ratio regardless of the differences among individuals manipulating the coating gun.
