Inner lining

Beitrag von BalladExchangeDB »

The inner lining for the hull is peeling away from the hull in the forepeak and the starboard pilot berth, perhaps caused by dampness and bouncing across waves this summer.

The lining has defied all attempts so far to restick it, including double sided carpet tape and elephant tape. The back was evidently a type of foam originally, which has decayed into a revolting slime which gets everywhere. It is possible to vacuum it off to some extent, but this doesnt seem to help much in sticking it back up.

I see from photos on the group that others have removed the lining. Does anyone have any ideas about how to put it back up in one easy step. Unfortunately there are more pressing other issues and I do not relish a major stripdown. In particular any ideas on how to remove the mess (mixture of old glue and the foam backing) and any recomended glues for relining

Any ideas welcome

Hi Rosie

This is not what you asked for, but it sounds like the lining has to be removed, the remaining foam has to be sanded off, and a new lining has to be installed with the proper type of glue.

It's a big taks, I understand why you want to avoid it.

The same happend to me. I managed to delay the work by using quick-epoxy glue that kept in in place for a couple of years before I replaced it all.
And when I replaced it, I started marking up exactly how the new lining should look like on the old one before I tore it down. Then I did the new one at home (10 mm isolation and vinyl at top) so they fitted exactly, which made the work fairly easy (but still time-consuming)...

I did stage one of this job five years ago. Have still to do the hull behind the main berths which is this winters job. Once the foam back has perished you need to renew with new foam backed vinyl. I bought the material from Hawke House Marine in Gosport UK. Removed the old vinyl scraping off as much loose foam as possible,coating the hull with brush applied contact adhesive and using a spray can of the same to coat the back of the foam. It's a two handed job as once the two surfaces meet that's it ,but using the old vinyl for patterns it all seem to flow nicely and we are stll talking.

Thanks for the replies. Jesper's comments about taking it all off and starting again filled me with gloom, but Peter's and Vinga's comments gave some hope.

Can you remember the exact type of epoxy glue or contact adhesive that you used. So far it is resisting all attempts to get anything to stick to it, but this may be due to dampness.

I have just read an article in an American sailing magazine about an owner of a Cal 29 who replaced the vinyl with cedar strips glued to the hull, which doesnt look too bad although would be a bit of a contrast to the current woodwork. The strips were originally cupboard lining. I wonder if anyone has tried something similar.

I don't wanna be gloomy again, but the idea of temporarily attaching all or parts of a vinyl lining with epoxy, makes me think of the hardship you will endure removing it again, or just smoothing it out, when preparing the hull for a new permanent lining. I would imagine the local yacht equipment store has a glue, somewhat similar to the glue used for wall paper, suited for vinyl lining with a foam backing. It has to be a thick glue that will soak the remaining foam completely, and bond to the vinyl itself, since the foam has probably gone bad by now and has no strength. This glue should also be soft enough when hardened that it could be scraped off, instead of sanded down. If I was in this sort of trouble, I would talk to a boatbuilder or boat interior builder, or the local equipment shop.

I really hope you find an easy solution, because the perspective of total renewal of inner lining truely is gloomy.

Hi to all those troubled by peeling liners.

When I bought my Ballad nine years ago, the lining on the cabin sides had already started to peel. Rather than using foam-backed vinyl, I opted for relatively thin beige carpet. After scraping off the disentigrating foam and lightly sanding the fiberglass, I cut the carpet to size, applied contact adhesive on both carpet and fiberglass and positioned the pieces. To this day, there's no evidence of peeling.

Originally, on my boat, the forecabin sides were made of very thin mahogany-stained plywood sheets. Last year, when I re-did the forecabin, I upholstered the plywood sheets with velvet-soft beige carpet which brightened up the interior and is very nice to the touch. It's also easy to clean: even rusts stains from a weeping cleat backing plate were removed with carpet cleaning liquid. Also, between the fiberglass sides and the plywood sheets, I attached 12mm self-adhesive foam insulation sheets, which help keep the interior warmer in winter and cooler in the summer. The latter is particularly important since my hull is dark red and gets much warmer than a white one.

I agree to Jespers comment on beeing careful not to create a large job by applying lots of epoxy that has to be removed later. I only fixed the lining on small spots with some 20-50 cm distance on the top of the lining. It did not look perfect, but it kept the lining from falling down. I used araldite super quick (hardens in a few minute) if I remember correctly, and glued 2 spots at the time, so I could keep it in place with hands only while hardening.

I have a 1975 Ballad, TROUBADOUR, on the Chesapeake Bay and I have begun to replace the foam liner in the boat. I carefully scraped away all of the residual backing with a flexible painter's knife and am using 3M Foam Fast 74 spray adhesive. After measuring the area to be covered and making a paper pattern to be sure, I work from one end of the panel to the other carfully positioning the liner as I go.Be very careful to ventilate the cabin while using this product. I would recommend wearing a respirator, gloves, and eye protection. I started in the quarter berth in case I had problems-so far so good.

Hi Rosie
I had to remove some vinyl lining recently. The most difficult part of the job is to remove the glue and foam that remains on the hull. I started out using a wire brush but I reckoned that there had to be an easier way than this. After trying a couple of different solvents I fount that unleaded petrol softens up the glue and foam so that it can be removed easily. The procedure that I used is as follows:
1) Peel off the old lining and vacuum any loose foam that remains on the hull.
2) Paint unleaded petrol on the remaining foam using a paintbrush.
3) Use an abrasive pad like that used to clean pots to remove the foam and glue.

I used an aluminium pot scrubber but steel wool will do the same job. Parts 2 and three may have to be repeated again but you will find that the unleaded petrol is very effective. The paint or flow coat on the hull inner is not effected. I hope this helps.
Regards Eamonn.

Hi Folks, I have similar problems on Temptress but in addition to hull linings issues previous owner at one stage painted interior of coachroof with a domestic exterior wall type paint which was flaking - Temptress had dandruff which had to go! I removed all coachroof interior fittings,grabrails,lights winches,cleats etc, sanded and wirebrushed interior coachroof and then lined the interior with 3 mm ply in 4 strips covered in vinyl which I glued to the ply with a PVA type glue. I tried contact glue but that was a disaster as it was most difficult to line up properly,especially the fold-over on edges and corners not to mention the air bubbles. I then screwed the strips to the coachroof and covered the joints with strips of varnished oak. I took the opportunity to replace/relocate the interior lighting by running cables behind the oak strips I then replaced the grabrails and rest of interior hardware. As part of the winter layup tasks. I also stripped the interior varnish by a combination of chemical stripper, hot air gun and sanding. These tasks have really cleaned up and transformed the main cabin interior of Temptress but the forecabin lining remains for another season. I will take and post some photos of the coachroof job
