A method of making a ceramic honeycomb article which includes: applying at least one green membrane coating layer on a green substrate, the green substrate comprising a plurality of cells comprised of a plurality of interior channels and a plurality of porous interior walls between the channels; drying the at least one green membrane coating layer on the green substrate to produce a green coated substrate; and firing the green coated substrate into a porous substrate, wherein applying the at least one green membrane coating layer and the drying the at least one green membrane coating layer are repeated from 2 to 10 times prior to firing to form multiple green membrane coating layers on the green substrate and wherein the firing the green coated substrate forms a ceramic honeycomb article comprised of the porous substrate and multiple fired coating layers on the porous substrate.
