Will New Headlining Glue Stick Onto Old Headlining Glue?

Hi,

Above my galley and chart table is a headlining that spans nearly 8' of beam x 4' of length. It has a companionway hatch, instrument access hatch and Lewmar hatch cut outs. It also appears to be bonded in place as I cannot remove the panel; it is made from three panels butted together with a filler over the seams faired in.

I have removed the old head lining and the usual mess was left stuck to the panel. So far I have scraped all the old foam away but the old glue is still in place. I tried some acetone to rub off the glue but that didn't really work, just dissolved and smeared the fine foam bits embedded into the old glue.

So, my plan is to rough up the surface with coarse sandpaper, wipe it down and then roller on new glue and stick up the new foam backed vinyl. What do you think, will the new glue adhere onto the old glue successfully and long term, or will this just be a waste of time and effort.

Thanks,

" will the new glue adhere onto the old glue successfully and long term, or will this just be a waste of time and effort " AND MONEY!.


I personally don't think it is a good idea. since you have got this far it seems a bit silly to risk the failure, just for the sake of removing the glue that's left! I would actually try to remove the existing glue with some sort of mechanical sander as solvents will just make a mess and make things worse.

Be sure to wear some sort of respirator and paper suit as fibre glass particles are nasty things.

I actually replace a fore peak headlining in a westerly Centaur once, and it was surprising how easy the glue and foam came off!

Best of luck with it.
 
Thanks for the replies, I have decided to remove the panel and use it as a template for new panels. Whatever the panel is bonded too, it is not much in the way of bonded area as I can flex the panel between bonded bits. Old boats, ya just love them!
 
Sorry misread your post, thought headlining was stuck directly to the inside coach roof moulding.

You will probably find if they are separate panels they are stuck onto timber grounds, which will have been bonded direct onto the underside of the coachroof. Usually the panels are face fixed, but yours seem to be closely fitted and glued?

I think you have made the right choice, and will not regret it in the long run.

If you are making new plywood panels for foam backed headlining stick it on with a water resistant PVA wood glue.
It is water base so there are no hazardous solvent fumes and no smell

Hawke House supply Tradebond WA40 for the purpose. http://www.hawkehouse.co.uk/adhesives/wa40-1-litre.html

The old glue comes off easily with a "face off" disk on an angle grinder. Hawke house sell them.

There are also lower speed options for electric drills..

The face off discs work well, but generate a lot of glass fibre dust (if working cleaning up the inside of the hull). Not nice.
They don't actually do any real harm to the surface but disturb and remove any surface loose material. Lots of cleaning up afterwards.
I can't imagine a grottier job. Has to be done mind you if you want a good clean dry surface to re-stick lining.
 
Assuming the panel butts up against he cabin side or similar and is curved, it will require very little to hold it in place once flexed into position. I'd favour the idea of the flex being the main hold, with some velcro padds to ensure it doesn't move. Apart from being easier to do, less need to get a truly clean surface, it can be pulled down when required say for running new wiring above the panel or access to deck gear fasteners.

I am beginning to like this velcro idea, especially for removing panels for a later rewire.

Thanks everyone.
