Headliner Insulation Adhesive Glue

I am adding sound deadening and insulation to the ceiling and back wall. Originally there was some adhesive holding the insulation to the ceiling.
What adhesive should I use? Glue it to the ceiling? Maybe no adhesive is good? Low oder would be good, especially when it gets hot. And it doesn't have to be super strong. Keeping flexibility would also be good. Maybe I should start searching the glue that is used for the floor insulation I am using! Maybe I just answered my own question.

 

I've been researching myself.......I have a can of gorilla glue, but a little worried about the heat here in the south...

this is what I've eye'ed unless someone has something better that dont cost $50 or $60...

The the big deal not strength, its heat resistance and a quick cure time...
contact cements are notoriously slow...

secure adhesion in 15 seconds to 30 minutes

 

It's the stuff that kind of looks like hot glue, right? I'm in the process of doing the same thing and was thinking maybe 3M headliner / carpet adhesive would work - spray it on the back and then press it up against the ceiling. Not the same thing as what the factory used but it seems to be the closest thing you can get at a store. That or it's some silicone RTV but I think that stuff has a different consistency.

 

3M makes a spray on upholstery adhesive which is used specifically for bonding insulation and headliners to roofs.

Formula dries in 30 to 60 minutes.....oops

 

i just used the 3m headliner spray.
good stuff

 

yes like hot glue. I tried window silicone thinking it has some adhesive quality, plus it was new and laying around. The adhesive silicone is not strong enough.

This looks promising. Of course any headliner adhesive is probably the most promising for the insulation, lol. But I'm stuck looking for the tacky flexible stuff. This works for extreme temp variation on metal in the same location. I am giving it a shot.

 

Hi all, the ceiling carpeting in my camper shell has started to sag a bit in several spots. I'd like to cut a very small hole in the carpet in each spot and spray an adhesive inside via a straw.

Any recommendations for an adhesive that won't clog in the straw? I also need to figure out how to keep the carpeting pressed upward as the adhesive dries. Thanks!

 

I know there's clear pins you could potentially use depending on what's behind the fabric(foam vs nothing but metal/fiberglass). I don't think the Permatex or 3M cans come with straws, but maybe the nozzle can fit one? This post says they can and had good result: https://gbodyforum.com/threads/tip-cheap-easy-headliner-repair.21670/

"Correct" fix would be to remove the headliner entirely and pull the fabric off, spray with the adhesive and reapply (probably with new fabric). Not sure how the camper's headliner is set up though if they attached it directly to the metal/fiberglass or not.

 

Having done this job for many different types of vehicles my advice is to clean the cardboard surface well, any imperfection will show and practice with the material before you spray glue. Too heavy of an application will bleed through the material. I like to wrap it to the backside and glue it there too this gives it a clean edge especially where there are not any trim pieces to cover the edge.

 

This stuff has worked great and you can get it at most parts stores.

 

I'm about to do my headliner too. This is what I always use on vehicle upholstery now:

They say you can spray it - never tried, but I might this time

btw all of these glues will be pressed when dry-to-tacky. You don't press it until it dries for a few mins, then it's instant hold
