PURPOSE: An apparatus for spraying polymer mortar compositions and a method for repairing a concrete structure using the same are provided to prevent the clogging problem of the polymer mortar compositions. CONSTITUTION: An apparatus for spraying polymer mortar compositions includes a mixer(12), a water pump(14), a hose(16), a spraying nozzle(20), and an air compressor(18). The mixer mixes polymer mortar compositions. The water pump supplies water to the mixer. The hose transfers the mixed polymer mortar compositions. The spraying nozzle is installed at the end of the hose and sprays the polymer mortar compositions to a target position. The air compressor supplies compressed air with high pressure to the spraying nozzle.
