Use a bottle of special automotive glue or adhesive product, spray the glue along the edge after peeling it open, let it dry for 3-5 minutes, and then press it back into place. Here is some related information about car interior ceiling fabric: 1. Function: The car ceiling fabric is an important part of the vehicle's roof, primarily serving to enhance the interior decoration. Additionally, the composite fabric of the car ceiling can improve insulation and heat resistance from the outside, reduce interior noise, and enhance sound absorption. It improves the comfort and safety of passengers. 2. Material: Textiles account for more than 50% of the materials used in car ceiling fabrics. Automotive textiles mainly include woven fabrics, knitted fabrics, non-woven fabrics, and fiber composites, with knitted and woven fabrics being the two main categories.

The fabric on my car's headliner had come loose, so I decided to fix it myself. The method involved using automotive-specific spray adhesive, such as the 3M brand. First, I thoroughly cleaned both the fabric and the roof surface, removing dust and old adhesive. Then, I sprayed adhesive on both surfaces, waited for half a minute, and gently pressed the fabric back into place, smoothing it out from the center outward. After the repair, I left it overnight to cure. The entire process took about two hours, with material costs under 100 yuan, whereas a professional shop would charge four to five hundred. I recommend choosing a high-strength, odorless adhesive and ensuring good ventilation and wearing gloves during the operation. Regular inspections for prevention are better; I usually park my car away from direct sunlight to prolong the adhesive's lifespan. It's been over a year since the repair, and there's been no recurrence.

As someone frequently involved in car maintenance, I recommend taking your vehicle to a professional repair shop for sagging headliner issues. DIY fixes may not last long, especially when the fabric is severely aged. Technicians can assess whether the entire headliner needs replacement and have the proper tools to complete repairs quickly, usually within one to two hours. The cost is approximately 500 yuan, varying by car model, which is more cost-effective than repeated fixes. From a safety perspective, dangling fabric can obstruct vision while driving, so prompt attention is advisable. Keeping the interior dry is key to prevention; using dehumidifiers during rainy seasons reduces the risk of adhesive deterioration.
