PROBLEM TO BE SOLVED: To provide a method and an apparatus for coating a ceramic monolithic support with a catalytic slurry wherein a deviation in the upper and lower sides of a coating amount can be minimized in coating the monolithic support. SOLUTION: In the case where a monolithic support which is not coated by anything is placed and pressurized or sucked, conditions for pressure and time are previously set so that pressure is stepwise or continuously changed and so that all pressurization or suction time is made T hours, an x1 pressure is applied for initial t1 hours, an x2 pressure is generated for the next t2 hours, and an x3 pressure is generated for the succeeding t3 hours, wherein, T=t1+ t2+t3+...+tn(n>=2).
