Author Topic: Head Liner Sag (Read 3894 times)

Two very small sags have appeared in my sedan's headliner., each about 2 inches in size.. However I pressed them in and they appeared to have stuck back up for the moment...
Question.. I was considering dampening them and applying a Hair Dryer to shrink the fabric...
Any thoughts..Suggestions??

I'd cut a small 'x' in the sagging fabric. Then I'd spray some good 3M adhesive (say 75 or 90) trying to get it on both the headliner & foam backing (but not on the outside). Then let it dry to tackiness and press it in place. It'll stick nicely if the glue is dry enough.

The best solution is to re-cover the whole thing, but a few patches will get it by until you can pull the headliner.

Thanks Dave, I was considering that myself....
The spray fabric glue such as those from Wilson Art etc... are very liquid.
As such I was considering spraying through a tube as with WD-40. As the two the small sags are half the size of space on which I am posting this message and by the edge of the liner I am thinking I might get away with the minimal repair....

So, you don't think the idea of shrinking the fabric with a hot hair dryer has much merit?
Especially being such a small spot.. I realize that the Hot Hair Dryer could possibly unglue even more of the liner. Keeping that in mind I was hoping to to find someone who had already made the attempt..

The areas where it is sagging is the result of the foam backing deteriorating or coming off the headliner board and based on my experience, spraying new adhesive on the old adhesive isn't going to do anything but make a mess. I replaced a pretty badly sagging headliner on a friend's car using the info on this link: http://www.wlsheadliners.com/1991-bmw-525i-headliner-installation-guide.html I bought the BMW kit (http://www.wlsheadliners.com/bmw-jaguar-volvo-audi-saab-headliner-kit.html), but opted for 2 cans of 3M adhesive instead of Dap.

I'm no upholstery expert and my first job was probably a 7/10. Still, it was good enough for other people to ask me to do their cars and I picked up some tips that I'd be happy to pass on if you're interested.
