A method for repairing cracks in an exterior wall of a building structure according to the present invention comprises steps of: removing impurities from a construction target surface and performing pretreatment; forming a corrosion-preventing layer by applying a corrosion-preventing material to the construction target surface; forming a waterproofing layer by applying a waterproofing material to the upper surface of the corrosion-preventing layer; attaching a fiber sheet including polyester nanofibers to a crack occurrence site of the construction target surface; impregnating the waterproofing material in the fiber sheet by applying the waterproofing material to the upper surface of the fiber sheet; and forming a repair layer by applying a crack repair material containing calcite to the upper surface of the waterproof layer including the upper surface of the fiber sheet impregnated with the waterproofing material. 본 발명에 따른 건축 구조물의 외벽 균열 보수 방법은, 시공대상면의 불순물을 제거하고 전처리를 수행하는 단계; 상기 시공대상면에 부식방지재를 도포하여 부식방지층을 형성하는 단계; 상기 부식방지층의 상면에 방수재를 도포하여 방수층을 형성하는 단계; 상기 시공대상면의 균열 발생 부위에 폴리에스터 나노섬유를 포함하는 섬유시트를 부착하는 단계; 상기 섬유시트의 상면에 방수재를 도포하여 상기 섬유시트에 상기 방수재를 함침시키는 단계; 방수재가 함침된 상기 섬유시트의 상면을 포함한 상기 방수층의 상면에 칼사이트(calcite)를 포함하는 균열보수재를 도포하여 보수층을 형성하는 단계;를 포함하는 것을 특징으로 한다.
