Due to poor maintenance, the insulation material for the exterior walls of buildings may be exposed due to the detachment, damage, cracking, and large holes of the protective layer. Non combustible materials must be used to seal and cover the insulation material. When performing exterior wall cleaning and maintenance work, smoking and open flames must be strictly prohibited. Before carrying out maintenance work on exterior wall insulation materials, mark the sequence and install them one by one. The installation details lie in the flatness and hollowing rate, and the hollowing ratio can be controlled within 20%, while the flatness cannot have too much deviation, which can be acceptable at 1 ‰.

There are multiple external wall insulation processes, complex construction, and significant impact from the construction environment. Higher requirements are placed on the intrinsic properties of materials and the compatibility between materials. Improve the waterproof performance and airtightness of the wall, effectively protecting the main structure. Not occupying indoor space and not affecting indoor decoration. This maintenance work can also be flexibly disassembled and reused for installation in other buildings, and the remaining construction scraps can also be recycled and reused. The integrated panel for exterior wall insulation and decoration not only achieves insulation, fire resistance, and decorative effects, but also reduces the load-bearing capacity of the exterior wall.

Shandong has a wide variety of exterior wall insulation materials, and the quality of insulation boards on the market varies greatly. This requires us to carefully inspect and maintain them when purchasing. It can also be used in cold storage and refrigerated trucks. The superior resistance to water vapor and pressure of extruded polystyrene insulation boards makes cold storage buildings and refrigerated truck applications more advantageous. Before applying polymer mortar on the surface layer, a suitable amount of adhesive should be applied to the surface of the mesh cloth to bond and fix it. After the adhesive dries, polymer mortar should be applied on the surface layer.
