How to Fix a Sagging Car Headliner?

[VanKathryn]

First, edge detachment of the headliner is often caused by aging of the fabric sponge, leading to the edges coming loose. This issue is relatively easy to fix. Purchase a bottle of specialized automotive adhesive or glue product, spray the glue along the detached edge, let it dry for 3-5 minutes, and then press it back into place. Second, if the middle section of the headliner sags or detaches, it may be inconvenient to remove. In this case, you can opt for a clip repair method. As shown in the illustration: choose clips of a similar color. The downside is that it may not look very aesthetically pleasing, but it is a practical solution. Third, for large-area detachment of the headliner, you will need to remove the entire headliner, take off the old fabric, clean off the aged sponge on the surface, prepare a new piece of headliner fabric along with specialized headliner adhesive, apply glue to both sides, let it dry for 3-5 minutes, and then adhere it. Finally, reinstall the headliner. However, for better repair results, it's advisable to visit a repair shop, even though it may be a bit more expensive.
