What adhesive should be used for a detached car roof fabric?
2 Answers
For a detached car roof fabric, the selection of adhesive is as follows: 1. Soft foam fabric: Use solvent-based polyurethane adhesive or water-based polyurethane adhesive. 2. Hard foam glass fiber non-woven fabric: Use solvent-free polyurethane adhesive. Below are the types of adhesives used in cars: 1. Floor adhesive: Floor adhesives are divided into hand-sewn and pre-formed types. A well-made floor adhesive, whether board-type or handcrafted, can effectively prevent dust and dirt from penetrating the carpet, but its waterproofing capability is somewhat weaker. 2. Sealant: Provides good sealing performance under certain tightening forces, with excellent resistance to pressure, heat, and oil. It has good stability to media and does not corrode metal.
I've encountered car roof lining detachment several times, and I recommend using 3M Super Trim Adhesive, specifically designed for automotive interiors. It provides strong and safe adhesion. The repair process is simple: First, thoroughly clean the detached area, using cotton swabs dipped in alcohol to remove old glue residue and dust. After it dries completely, spray a thin layer of the new adhesive (avoid over-spraying), carefully align and press the lining into position, then place a heavy wooden board or books on top to maintain pressure overnight. For maintenance, avoid prolonged parking under direct sunlight to reduce UV damage, and don't use high-pressure washers directly on the roof lining during car washes - this ensures long-lasting repairs. I recently repaired an old car's roof lining myself using this method, and it's held perfectly for two years without re-detachment, saving money and effort. For large-area detachment or if you're unsure, it's safer to visit an auto repair shop to avoid compromising driving safety.
