Maintenance method of automobile interior ceiling: 1. In this case, the ceiling near the edge is degummed, and the edge is directly disassembled, sprayed with glue, dried for 3-5 minutes, and then glued. 2. The middle part collapses. It is not convenient to disassemble at this time. We can choose buckle repair. Choosing buckles with similar colors is not beautiful, but it is also a practical method. 3. The ceiling falls off in a large area. At this time, it is necessary to remove the whole ceiling, remove the old ceiling cloth, clean up the sponge with aging surface, prepare a new ceiling cloth and special ceiling glue, spray glue on both sides to dry for 3-5 minutes (just don't touch it with your hands), then glue it, and finally install the ceiling.
