The invention provides a process for coating a cylindrical carrier structure with a predetermined amount (target take-up) of a coating suspension, wherein the carrier structure has a cylinder axis, two end faces, an encasing face and an axial length ~, and a large number of channels running from the first end face to the second end face. The process comprises: a) vertically aligning the cylinder axis of the carri er structure and filling the empty volume of the channels up to a predetermined height H1 starting from the lower end face, b) removing the excess coating suspension through t he lower end face of the carrier structure down to the target take-up; c) turning the carrier structure 180.degree., so that the upper and lower end faces are exchanged o ne for the other, and d) repeating steps a) and b), wherein the heist H2, up to which the channels are filled in this case is given by H2-L-x-H1 where x is between 0.8 and 1.0.</S DOAB>
