Gathering Your Headliner Repair Supplies
For this project, you’ll need:
- High-temperature headliner adhesive (spray or brush-on).
- Upholstery cleaner.
- Microfiber cloths.
- Plastic scraper or putty knife.
- Painter’s tape.

How to Fix a Sagging Headliner
- Prepare Your Workspace: Park your SLK in a well-ventilated area.
- Protect Your Interior: Cover your seats and dashboard with a drop cloth or old sheets.
- Remove Obstacles: Depending on the severity of the sag, you might need to partially remove or loosen interior trim pieces that interfere with the headliner. Be gentle!
- Clean the Headliner Board: Use the upholstery cleaner and a microfiber cloth to clean the exposed board where the old adhesive is present. Let it dry completely.
- Apply the Adhesive: Following the manufacturer’s instructions, apply the headliner adhesive to both the board and the back of the fabric. If using spray adhesive, hold the can about 6-8 inches away.
- Press and Smooth: Carefully press the headliner fabric back onto the board, starting from the center and working your way outward. A small roller can help eliminate air bubbles.
- Secure with Tape: Use painter’s tape to hold the fabric in place while the adhesive dries.
- Reinstall Trim: Once the adhesive is dry (refer to the manufacturer’s instructions), carefully reinstall any trim pieces you removed.
Repaired Car Headliner
Frequently Asked Questions:
Q: Can I just use any spray adhesive for this repair?
A: It’s highly recommended to use a high-temperature headliner adhesive specifically designed for automotive applications. Regular spray adhesives might not hold up to the heat inside a parked car.
Q: My headliner is extremely saggy. Is it beyond repair?
A: While this DIY method works well for most sagging headliners, extensive damage might require a professional reupholstering job.
Q: Can a diagnostic tool like those offered by Cardiagtech help me identify the cause of my sagging headliner?
A: While incredibly useful for diagnosing engine or electrical issues, CARDIAGTECH’s tools won’t be able to pinpoint the cause of a sagging headliner as it’s primarily a wear-and-tear issue.
Conclusion
Fixing a sagging headliner in your 2001 Mercedes SLK 320 is a manageable DIY project that can save you a significant amount of money and restore your car’s interior aesthetics. With a bit of patience and the right materials, you can have your SLK looking its best in no time.
