Method for repairing cracks of external thermal insulation system of thin plastered external wall
The invention provides a method for repairing cracks of an external thermal insulation system of a thin plastered external wall. The method comprises the following steps of coating the surface layersof the cracks of an external thermal fish coating with an elastic high-viscosity waterproof sealing material, paving alkali-resistant anti-cracking gridding cloth on the elastic high-viscosity waterproof sealing material, and plastering waterproof anti-cracking mortar on the outermost layer of the elastic high-viscosity waterproof sealing material. The external thermal insulation system of the thin plastered external wall, maintained by the method can prevent continuous development of the cracks, has the effects of sealing, waterproofing, stress relieving, bonding and anchoring, and can effectively prevent stress conduction and water from seeping into a wall through the cracks to cause continuous cracking, exterior facing layer falling and other diseases. The method that the structure is recovered after an original heat preservation facing layer is shoveled is avoided, and it is guaranteed that the original heat preservation layer is not damaged.
本发明提供了一种薄抹灰外墙外保温系统裂缝的修复方法，包括外保温饰面层裂缝表层涂覆弹性高黏防水密封材料，其上铺设耐碱抗裂网格布，最外层批抹防水抗裂砂浆。通过本发明方法维修之后的薄抹灰外墙外保温系统可阻止裂缝的继续发展，起到密封防水、缓解应力及粘结锚固的作用，可有效防止应力传导及水分通过裂缝渗入墙体导致继续开裂、外饰面层脱落等病害，避免了铲除原保温饰面层再重新恢复构造的做法，保证原保温层不被破坏。
