Head lining adhesive

[gjh]

Trying to fit foam backed head lining to fibreglass and initially used "Super Spray Adhesive" for foambacked carpets - big mistake ! Although the results looked good it only lasted a few weeks before its started to sag. Can anyone point me at a suitable adhesive ?

Thanks in advance for any help.

I made the same mistake when trying to stop the droops. When I replaced the headlineing completely, I went to a proper adhesives wholesaler in Southampton and obtained the stuff used to stick car headlining up . You can get decent glue from a place just outside Gosport that advertises in PBO (Hawke house seems to ring a bell), but that is not really designed for continuous service in the med, but is used by 99% of peeps in UK. My glue cost as much as the felt backed carpet, which cost as much as the two carpet fitters I hired to do the boat, and still worked out at half the price I had been quoted for proper marine headlining!

Use an impact adhesive such as Evo stick, or the thixotropic version, Evostick Time Bond. I have used both the liquid and thixotropic ones and the latter is probably easier and less messy to use. However only apply to the fibre glass and use a spray adhesive on the foam backed vinyl. Coat the fibre glass and spray a band along the top of the vinyl, position that then progressively spray the back and work downwards. ( The spray I used was TGP Trade Tack, for foam backed carpets among other things.)

You can get suitable adhesives from Hawke House Marine in Fareham, although the suppliers of the vinyl should be able to offer you the right adhesives if they are worth their salt. I also bought my lining material from them and they sent me a very useful hints leaflet. A Google search will find them.

These adhesives are solvent (methylbenzeze, aka toluene) based and good ventilation is paramount. I also strongly recommend the use of an ''Organic vapours'' mask which also can be obtained from Hawke House Marine.

If you are also covering any wooden panels as part of the job you can use a water proof PVA wood glue, which is much more pleasant to use, is waterbased and may lead to a longer life for the foam backing.

You are not trying to restick old lining are you?

Shout if you need any further advice. I lined my boat when I built it 26 years ago and I relined it, making a much better job of it, 4 or 5 years ago. Also if you search these forums you will find the topic has been raised several times before.

Hi gjh,

I agree re Hawke House Marine, though they are not cheap! Their recommended procedure is to apply the 'Trade HH' adhesive (similar to evostick in consistency) to the grp/wood, and their spray adhesive to the foam. It's a brilliant system and extremely easy to use. As noted above, plenty of ventilation and a good quality solvent mask are essentials.

Incidentally, the 'HH' stands for high heat, and is designed to overcome the problems of degradation associated with the high temperatures encountered in the Med/Caribbean. I've just completed the entire re-lining of my boat and although it was a very tiring and lengthly process, using the above adhesives produced a superb finish.

Hopefully, the job will last me out now!

Good sailing!

agreed, you can't use spray on both surfaces, the hard surface has to be done with liquid. it's essential to use pray on the foam as liquid soaks all the way through to the vinyl and leaves a lumpy finish.

long term, foam will always fail, a more reliable way is to stick ply pads to the deckhead and fix plain vinyl using screws with caps.

for those who don't like to see the screw caps you can stick vinyl to 3 or 4mm ply and hold that in place with velcro and/or battens.

Screw caps covered to match the vinyl look neat and can be obtained from suppliers like Hawke House. I used a combination of these and strips of vecro to hold up the head lining panels.

If using velcro use two stips on the sustrate and two on the panel at right angles so that together they make the pattern of an octothorpe, aka hash (#). That way you dont have to position them so accurately.

I used vinyl flooring adhesive for my headlining. It's water soluble and has the consistency of yoghurt. As it's not a contact adhesive it enables you to move the vinyl around to get it in exactly the right position. Worked well for me.

Screw Caps

Screwfix do screw caps too. Pretty cheap. I used nickle plated screw cups & BZP screws which seem OK inside the boat - just don't do them up too tight as the cup can cut through the fabric.

I used a large tin of impact adhesive, and did all the fitting on separate panels outside - stopped feeling woozy about 30 minutes after finishing each panel.

Regards

Richard.
