Headliner

[Indiana]

Hi,

29ft SeaRay Sundancer 1992

I have attached two photos to this thread to highlight the condition of the deckhead now that I have removed some old wooden tongue & groove.

In the first photo you can see:
1) Darker orange colour which I believe is a good covering of glue adhesive (Still slightly sticky!)
2) A grey colour which seems to be the same glue as above but now dry & hard?
3) Yellow areas which are the perished bits of foam from a foam backed vinyl.
4) White which is the expanding foam used to insulate and hold tongue & groove in place.

In the second photo you can see:
The old slightly sticky/rubbery orange coloured glue which is covering a large area (Not patchy), which would be something I would reluctantly want to try and remove prior to recovering.

My first question is, can I just remove the two types of foam and leave the slightly sticky glue area alone, then glue a new foam backed headliner over the top ... Would it adhere properly.
I was surprised to find that this glue is still slightly sticky/rubbery after what looks to be many years.

My second question is, or can I use something like Thermozite as an insulator between the deckhead and a new foam backed headliner, also is Thermozite waterproof?

Many thanks,
Mark

It's a better idea to remove as much of everything as possible. Even that "still sticky" glue. Who's to say how much longer it's lifespan is? Better to start fresh. Besides, it's really not much extra work to do that.

I don't know what Thermozite is.

Thermozite is used for insulation in steel buildings because it acts as a barrier to condensation. Not sure it is "waterproof" as in use it underwater, but it does work in moist environments where condensation would ruin the insulating capabilities of fiberglass bats. Are you planning on installing the foil side up against the bottom side of the deck? Maybe a call to the product manufacturer could answer your question about your intended use to get their take on it. Seems like it should work.

Wire brush the old glue off, even the still sticky stuff.

Thanks guys for your comments, didn't really want to remove the old glue as there's a mass of it, quite thick, both hard and soft.
Thermozite was just one method I was looking at to insulate, and possibly act as a barrier to condensation, under the foam backed headliner.

Whatever I use I want a nice smooth result as I'm not sure foam backed vinyl on it's own will suffice (As may not hide all the lumps & bumps).

Once the headliner is up I want to run a wide Chrome style beading all around the edge to marry-up with the chrome around the head door, and seating.

All the vinyl on the walls and woodwork (Including the roller cabinet doors ... God help us!) have been painted over with white emulsion which I would love to remove but believe would be too difficult, so will over paint in colours that should hopefully compliment the rest of the interior (And new upholstery)

I will be back later for more suggestions on how to remove the side cupboard/draw panels as these look to be a little difficult to do.

Ta,
Mark

Glue... acetone, chemical resistant scrub brush, lot's of rags and a fan blowing the fumes out.

I had to remove a lot of old glue for a boat project and I used a wire cup brush in an angle grinder

It made short work of the old adhesive, foam, carpet backing, etc. sticky or not....but its messy and will throw old glue and shit everywhere. You will want to cover everything. For me it wasn't a problem as I was re-carpeting and I had nothing in the boat. When don, a shop vac took care of all the residue. Yes, use the mask and safety goggles.
