PURPOSE:To facilitate the judgement of adhesion amount, by method wherein a wt. is preliminarity printed on the outer surface of a monolithic structure when said structure is immersed in an aqueous slurry of a solid powder to support said solid powder and the printed structure is preliminarily covered with water repellent paint and, after the solid powder is adhered to the monolithic structure, the printed character is read to calculate the amount of the powder. CONSTITUTION:When a predetermined amount of coating is applied to a honeycomb structure composed of a metal or ceramic by immersing said structure in an inorg. powder-containing slurry, the following method is taken. That is, when it is necessary to apply heat-treatment to said structure later, the printed of a wt. is applied to the structure using heat resistank ink containing a manganese or cobalt compound and the printed structure is covered with transparent water repellent paint based on a fluororesin. Thereafter, if necessary,the volatile compound in the coating is removed under heating and the structure is immersed in an inorg. substance-containing slurry to apply coating to the structure. By this constitution, the wt. written on the structure by printing before coating and the wt. of them structure after coating are operated to judge whether a desired amount of the powder is adhered.
