Will this work?

[Tam Lin]

The headlining in my Centaur is coming down in patches. Not bad enough to replace yet. If I inject glue through the headlining and spread it around a bit will this work? If so what glue would be best? Thanks.

I looked at a Tiger that had had this treatment and it looked a right mess. I found a pic:



And another:


I have battens holding my Centaur headlining up untill I get round to a permanent fix, Searush has the same on his Pentland:

Copying the thumb code from PB has stopped working, is it me? The image code works by the look of it.

It might work for a while but it will eventually fail.
The reason the headlining is drooping is that the foam behind it disintegrates into a powder and no amount of glue will stick it to anything.
You really need to strip the headlining off and replace with new foambacked stuff or scrape all the old foam off and glue in a sheet of new foam and stick the whole lot back together.
Not a pleasant job.

Thanks for the photos FWIW did you realise that once I had opened the first one I could see all of the photos that you took of the boat? Your battens look good but as I have only got a few patches at the moment I don't think that I need them yet.
SAMYL - you are right of course, I was hoping to put off the inevitable for a while!

Foam backed headlining is IMO the work of the devil!
The way that I would go about it is to remove the disintegrating foam back and glue fabric, using PVA, to a thin plywood template using a paint roller to get the air out.
Note: The 'top side' of the plywood needs to be waterproofed to stop damp and mould.
Attach it to the 'roof' by glassing onto the 'roof' some wood blocks then use capped screws to attach the headlining.
If you want some insulation I would use the fan fold foam (sold by B&Q) that is used under laminated floors.

I see B&Q also do a self adhesive Laminate Flooring Underlay that might be worth investigation, it might be stiff enough to use in place of plywood.

On a Westerly 21 I've used PVA to get the lining to hold up. It seems to go into the foam and stops it getting worse (for how long I don't know 'cause I sold the boat 2 years later). I used a brush to paint onto the foam and then held it in place with thin ply panels until the glue dried. In theory it shouldn't work, in practise it does.

Injecting behind should work, just plenty of it.

Yep, all my holiday photos too if you get really, really, really bored.

Glue could work if the foam isn't too disintegrated. If it is then the gluing of cloth or carpet to ply & attaching to battens works well, this is forecabin of my last boat after same...

On our old Moody, not all the vinyl is foam backed. And it's not easy to tell. All the wood panels seem to be foamless - and respond to re-glueing. Agree, if replacing, avoid foam!

Westerly head linings are a disaster I replaced mine as someone suggested above by covering thin ply and screwing the headlinings in place. Mind you getting the old ones down was a real mess you need to get everything off the boat as the black dust gets everywhere.

Without wishing to seem overly sensitive, it's more that foam backed vinyl is a disaster.

Ok most folk call it the Westerly droop but my 1982 First had the problem with foam backed vinyl.
My mother's 1982 Jeanneau has the problem with foam backed vinyl but the vinyl covered boards hold it up in most places.

Wouldn't it be nice if we could all have new boats with nothing to do on them but sail.
