External wall insulation materials are widely used in building exterior wall decoration, building ceiling decoration, and independent design decoration. The integration of aluminum sheet insulation is mostly applied to exterior walls and combined with insulation core materials. It is a type of exterior wall insulation and energy-saving decorative material with a relatively single application scenario. When there are problems with the bonding of external wall insulation materials and there are holes or other gaps on the surface of the wall, they should be plugged to prevent the insulation materials from absorbing water and expanding, and from causing hollowing due to water seepage. For special areas such as thick walls (plastering board thickness of 3mm), 5mm thick cement slurry can be poured for curing after plastering.

The construction personnel evenly mix the external wall insulation materials and apply the bonding mortar to the back of the board with a scraper, and then push the board onto the wall with their hands; Then attach the suction cup to the surface of the board and use it to adjust the position of the finished board; Finally, use a ruler and a level to check the flatness of the pasted board surface. Good hydrophobicity and moisture resistance, due to the material itself, compared to other insulation materials, the insulation performance deteriorates due to water absorption. Extruded polystyrene board effectively solves this problem.

In order to enhance the bonding strength between extruded polystyrene board and bonding mortar for external wall insulation materials, manufacturers can apply a thin layer of special interface agent on the bonding surface of the extruded polystyrene board before pasting; After the interface agent has dried, polymer bonding mortar can be applied for wall pasting construction. During construction, ensure that all switches and plugs and sockets are free from problems, electrical switches should be used within the specified range, and all equipment should be grounded. If there is a malfunction, it cannot be used, and overloading should not occur during equipment operation.

Ensuring the actual decoration and insulation function of the exterior wall fireproof insulation board is very good, with reasonable characteristics, and also brings important basic functions to daily life applications. Convenient construction while ensuring quality can better improve the practicality of insulation materials and building design. On the one hand, it can make the surface rough and uniform, which is conducive to adhesion. Its tensile bonding strength, water resistance, and freeze-thaw resistance with adhesives and plastering mortar are all above 0.25 MPa, greatly improving the system's bonding strength and increasing reliability.
