The accuracy of the coating concentration when applying a catalytically active coating to suitable carrier bodies can be increased if, following raw coating with a relatively wide fluctuation range in the coating concentration, excessive or insufficient coating applied is if appropriate corrected iteratively. Excessive coating suspension applied is removed, for example by subsequent suction, while the coating is still in the wet state, whereas insufficient coating suspension applied is topped up, for example by spraying on additional coating suspension.
