A method of soak type coating for a substrate being coated with coating liquid provides a pump to regulate velocity of gas being introduced into a container to control discharge velocity of the coating liquid in the first container so as to control velocity of the coating liquid separating from the substrate for obtaining better control of thickness of the coating layer on the substrate. Wherein, the gas introduced into the container is incapable of occurring chemical reaction with the coating liquid for obtaining preferable effect of coating.
