A method for repairing a continuous casting mold is provided to simplify the repair process without using an additional mask device by employing a cold spray coating process. In a method for repairing a continuous casting mold, a cracked part or a partially worn part of the continuous casting mold is polished. Copper powder or nickel powder is coated onto the polished part by using a cold spray system. Then, the coated part is polished. The size of the copper powder or the nickel powder is about 1‘í to 50‘í. The cold spray coating is performed by using a mixture powder which is obtained through mixing silicon carbide powder or alumina powder with the copper powder or the nickel powder. A volume ratio of the silicon carbide powder or the alumina powder is 50% or less.
