Building outer wall cracking maintenance method
The invention discloses a building outer wall cracking maintenance method. The method comprises the following steps that a crack and the edge of the crack are cleaned, the inner edge and the outer edge of the periphery of the crack are coated with a base layer treating agent, and finally the crack is coated with nano seam plugging paste and the nano seam plugging paste is flattened to enable the nano seam plugging paste to be consistent with an outer wall facing layer. Because the nano seam plugging paste shows plastic physical properties when not cured, new leakage caused by wall crack growthcan be resisted; and after the nano seam plugging paste is cured, a high-elasticity impermeable film is formed at the crack part of the wall body, rainwater is prevented from permeating into the wallbody along with the crack, and the super-strong crack resistance is achieved, so that leakage of the building outer wall is simply, conveniently, continuously and effectively prevented, and the attractiveness is improved to a certain extent.
本发明公开一种建筑外墙开裂维修方法，步骤包括先清理裂缝及其边沿，再在裂缝内及周边外沿涂刷基层处理剂，最后沿裂缝涂抹平纳米堵缝膏并抹平纳米堵缝膏使纳米堵缝膏与外墙饰面层一致。鉴于纳米堵缝膏未固化时表现为塑性物理性能，可抵抗墙体裂纹生长产生新的渗漏；而纳米堵缝膏固化后在墙体裂纹部位形成高弹抗渗膜，防止雨水随裂纹渗透到墙体内，且具有超强的抗裂性，从而简单便捷且持续有效地防止建筑外墙渗漏并在一定程度上提升了美观性。
