PURPOSE: A secondary surface-treatment brush for a decorative wood board is provided to minimize digging on a soft part of a wood board because the ends of steel bristles spirally rub against the surface of the wood board. CONSTITUTION: A secondary surface-treatment brush for a decorative wood board comprises a cylindrical roller(210), fixed blocks(220), and brush members(230). The cylindrical roller has joint units which are arranged at regular intervals and a rotary shaft(212) which is fixed in the center thereof. The fixed blocks have coupling holes(221) which are aligned with joint holes(211a) of the joint units and coupled with fasteners(S), and the fixed blocks are fixed at regular intervals in the circumferential direction on the outer periphery of the cylindrical roller. The brush members are fixed between the fixed blocks.
