, construction preparation
The base wall should comply with the "Concrete Structure Engineering Construction Quality Acceptance Code" () and the "Masonry Engineering Construction Quality Acceptance Code" () and the corresponding base layer Wall quality acceptance specification requirements and passed the acceptance. The performance indicators of polyurethane should comply with the requirements of "Spray Polyurethane Rigid Foam Insulation Materials". The wall surface should be clean and free of oil stains and floating dust. Construction holes, scaffolding eyes, balcony panels, and wall defects should be repaired neatly with mortar. Loose and weathered parts of the wall should be removed. The flatness error of the base wall shall not exceed.

, environmental requirements
, the weather during construction operations should meet the following conditions. During on-site spraying operations, the ambient temperature should be ℃℃, but should not be lower than ℃ or higher than ℃ The moisture content of the wall should be %, the wind force should not be greater than equal/(level wind), and the relative humidity should be less than %. No construction is allowed on rainy days. When the ambient temperature during construction is lower than ℃, reliable technical measures should be taken to ensure the quality of spraying. It is strictly prohibited to operate under high humidity or exposure to the sun.
The technical conditions for external insulation construction and operation are as follows
Single-row or double-row steel pipe scaffolding along the outer edge. The distance between the steel pipe portal scaffolding and the decorative surface of the wall should be (.m), and the maximum distance shall not exceed meters. The construction of guardrails no larger than 1.3 meters must comply with the current national safety technical regulations. The erection of scaffolding should meet the progress requirements of spraying.
Polyurethane white materials and black materials should be stored sealed in a dry, ventilated, and cool place. The storage temperature of white materials should be between ℃ and ℃. It should not exceed ℃ and should not be exposed to the sun. The appropriate storage temperature for black materials is ℃ ~ ℃, which should not exceed ℃, and the minimum storage temperature should not be lower than ℃. The storage period of polyurethane white material and polyurethane black material is two months. Sun protection measures should be taken during storage and transportation of polyurethane white and black materials.
