saggy headliner

[kashurst]

the headliner on my fairline has developed a few bulges. it seems that the foam backed cloth that is stapled to the plywood panels has separated from the foam and is hanging down looking a bit scruffy. apart from taking the whole lot down and re-doing it does any one have any tricks for restoring the adhesive contact between the foam and the cloth liner ???

Alas no. I've always undone the staples along 2 sides of the panel and reglued/restapled the whole thing with spray evo-stick type glue.

BUT - are you sure it is the cloth and the foam that have parted? I've always found it to be the foam and the plywood that have parted, ie a F'line assembly fault

You could inject glue with syringe but the holes would show and you'd need quite a lot of them

Fairline can be bad at this - I had a few of these incidents on both my 2004 and 2009 Sq58s. Their guys spraying the adhesive on need to be more careful. As I say, in my experience it has been the foam-plywood bond that has failed

I agree; in my experience the foam backing goes hard and brittle and crumbles, losing all adhesion. Better to replace than bodge a repair in my opinion.

It's only a thought. I always think that 'buttoned' upholstery looks very attractive. It's dead simple to do a will provide support for your saggy bits.

It's not their fault. It's the spray-on adhesive. Works fantastically for about a year or so, but gives up the ghost as soon as the ambient temperature gets above approx. 32 degrees.

Answer is - as jfm says - remove the panel, remove the fabric/vinyl/whatever covering and re-stick it using proper Evo-Stik adhesive. Make sure the room's well ventilated, or you'll end up ripped to the tits on the fumes.
