1. Grassroots requirements
Wall flatness: The base wall surface needs to be flat, with a flatness error of ≤ 3mm/2m, to ensure the stable installation of the keel dry hanging system
Structural strength: The base wall should have sufficient bearing capacity, the concrete wall strength should be ≥ C20, and the lightweight partition wall needs special reinforcement treatment
2. Environmental conditions
Temperature range: 5 ℃~40 ℃ (for temperatures below 5 ℃, special low-temperature fasteners are required)
Ventilation requirements: The installation area should be kept ventilated to avoid the accumulation of adhesive volatiles
Lighting conditions: Avoid direct sunlight on the work surface (SPC decorative pre installed protective film)
4. Installation specifications
Joint treatment: Reserve 3-5mm expansion joints between boards and fill them with specialized elastic rubber strips
Fixed requirement: no less than 8 dedicated anchors per square meter, with encrypted edges
5. Storage and transportation
Board storage: horizontally placed in a dry environment, with a stack height of ≤ 1.2m and SPC facing upwards
Handling requirements: Vertical transportation, avoiding bending, and the decorative surface needs to be fully covered with protective film
Note: The entire process is dry operated, and the joint closure can be carried out immediately after installation without a maintenance period. Before large-scale construction, it is necessary to conduct a sample wall inspection.
