What are the problems of building external wall insulation board?

Construction plan and preparation of materials. Before construction, a special construction plan and technical documents shall be prepared to ensure that the materials such as thermal insulation board, glue, mesh and other materials comply with relevant national standards, and checked before construction.
Grass wall treatment. The surface of the mass wall must be clean, hard and calm, and the adhesion that interferes with the bonds from oil, molding agents, etc. Field
Use of adhesive. The adhesive should be applied evenly to the insulation board. Pay attention to the thickness and uniformity of application to ensure that the insulation board adheres firmly to the wall.
Placement and handling of the insulation board. The insulation board must be vertical on the ground to support the horizontals and avoid tilting or dislocation. Special parts such as windows and doors must be properly treated.
Use of mesh fabric. The mesh fabric should be close to the surface of the heating plate to avoid seams, to ensure the overall amount of the wall.
Waterproof and fire prevention measures. Strengthen the waterproof treatment of the outer wall, select the right fireproof coating or additive, and improve the fire resistance of the wall.
Safety Operation Rules: During construction, we must comply with safety procedures, and it is strictly prohibited to use mechanical and electrical equipment privately to prevent falling or damage from high places.
Environment Temperature and Humidity Control: When building in low temperature or dry environment, heat and humidity control measures should be taken to avoid cracking or falling of materials.
Construction sequence and material management. According to the requirements of the project and environmental conditions, the construction order is reasonably organized, and the material installation and processing costs must be paid.
