Precautions for the construction of perforated gypsum board sound-absorbing board ceiling

1. Before installing the ceiling, ensure that the room is dry and clean to avoid affecting the installation effect.
2. During the installation process, the keel should be flat and firm to avoid shaking or sinking.
3. When using filling materials, the filling should be dense to avoid hollows or gaps.
4. When decorating, ensure that the painting is uniform and the color is consistent to avoid color difference or brush marks.
5. After the installation is completed, a comprehensive inspection should be carried out to ensure that the installation quality meets the requirements.
