Solution

1. Preparation

Gather tools: utility knife, adhesive spray (headliner adhesive), cleaning cloth, and a soft brush.
Remove any items or trim pieces that may obstruct access to the headliner.
Ensure the vehicle is parked in a well-ventilated area.

2. Clean Sagging Areas

Use the cleaning cloth to wipe down the sagging sections of the headliner.
If there are any stains, use a gentle upholstery cleaner to remove them without damaging the fabric.

3. Re-adhere the Headliner

Shake the adhesive spray canister as directed.
Lift the sagging section of the headliner gently.
Spray a thin, even layer of adhesive onto the exposed foam and the underside of the headliner fabric.
Press the headliner back into place, smoothing out any wrinkles or air bubbles.

4. Secure the Headliner

Use a soft brush to press down on the headliner and ensure it adheres well.
For larger areas, consider using clamps or tape to hold the headliner in place while the adhesive sets (follow the adhesive instructions for setting time).

5. Reassemble Interior Trim

Reinstall any trim pieces or components that were removed in the preparation step.
Ensure all components are securely fastened.
