A method for reinforcing a fouling control coating of the invention comprises a step of forming a reinforcing coating (O) by applying and curing a reinforcing coating composition [o], and a step of providing a fouling control coating (X) formed by applying and curing a fouling control coating composition [x], onto the reinforcing coating (O), the reinforcing coating composition [o] comprising an organopolysiloxane (AO) having two or more silanol groups or hydrolyzable groups in the molecule, and a pyrithione salt compound (BO), the fouling control coating composition [x] comprising an organopolysiloxane (AX) having two or more silanol groups or hydrolyzable groups in the molecule, and an antifouling agent (BX), the reinforcing coating (O) giving reinforcement to the coating (X) adhering thereto. According to the present invention, high impact resistance can be imparted to fouling control coatings. As a result, the peeling, chipping and loss of the coatings by external physical damages which are often encountered in the conventional coatings can be remedied, and stable antifouling performance can be obtained.
