Spraying protection and precautions
Release time:

For the thermal insulation and sound absorption layer after spraying, ventilation and dry environment should be provided. Usually, when the average temperature is 25 ℃ and the relative humidity is less than or equal to 60%, the drying and curing time is 24~72 hours according to different thickness, and then other processes such as decoration can be carried out.
Finished product protection by spraying
Before spraying, various pipelines, air ducts and other equipment hangers shall be installed to avoid drilling and chiseling on the base surface after spraying.
During the drying and curing of the finished product, avoid mechanical impact and rain erosion.
When the spray coating is damaged due to collision, local repair shall be carried out. For the parts that are often vulnerable to mechanical collision, glass fiber cloth or other protective materials can be pasted to protect the surface of the fiber layer.
Keep the environment of the spraying area clean to avoid dust flying and contaminating the surface of the finished spray coating. In the process of spraying construction, spraying operators should wear dust masks in accordance with the relevant provisions of the national labor protection regulations, and high-altitude operators should wear safety belts and other protective equipment.
