A process for applying a coating to honeycomb structures in an exhaust gas converter which contains two such honeycomb structures in a common housing or enveloping tube which are arranged one after the other and which are separated from each other by a gap. The coating dispersion is first supplied from one end of the exhaust gas converter up to the gap between the two honeycomb structures. Then excess coating dispersion is driven out using a blast of air from the direction of the uncoated honeycomb structure. To coat the second honeycomb structure, the exhaust gas converter is inverted and the coating dispersion is then applied in the same way but from the uncoated end. Following the dispersion coating procedure, production of the catalyst is completed by drying and optionally calcining.
