Last year I replaced the headlining on my old car. It's a foam backed
nylon material which is glued to a fibre former. The instructions were to
use spray on contact adhesive which I got from the same trim suppliers. 
 And it's failed in several places - mostly where it's most under the
highest tension, like the dimples behind the grab handles.

 I'm wondering if the moisture content in the fibreboard was too high - I
did have it indoors for a couple of days before doing the job but perhaps
it needed longer?  

 Anyway - I'm going to do it again. The material isn't too expensive. So
what should I use to give a better grip to the fibreboard? Soak it in a
PVA solution? Anything else?

Use evostik.

PVA will wet it.
Maybe a thin coat of contact adhesive left to dry as a sealer would work 
better.
There are primers for some contact adhesives or at least I remember seeing 
what I thought was a primer a few years ago.

If diluted a bit, the PVA might soak in better and stabilise the surface 
of the fibreboard but the contact adhesive would be more likely to go 
off on the surface leading to the same problem as before.

I hear what you say about the wetness though.

Reports say Evostick isn't what it was. It's also difficult to apply to a
thin fabric evenly.
