WASHCOAT METHOD
A method of washcoating a porous ceramic substrate, the method comprising:(i) pre-treating the substrate to form a pre-treated substrate;(ii) contacting the pre-treated substrate with a washcoat composition, wherein the washcoat composition comprises a washcoat solvent and a refractory material (such as a high surface area refractory material),wherein step (i) comprises pre-treating the substrate so as to substantially prevent ingress of the washcoat solvent into pores of the substrate and wherein the porous ceramic substrate comprises a plurality of channels and a plurality of micro-channels.
