Roof Liner - How To Get Trim Piece Off?

[Nomad Mike-WO]

So my roof liner sags in a few places and has popped open at this trim; I know from research it is a common issue.



I've seen several threads on repairs and the one commonality is that spraying glue and sticking it back will not work.

I'm planning on getting this trim piece off and maybe scraping any foam insulation off under the trim piece to get to the luan. I will then use a 3M spay adhesive and staples and then put the trim back.

Question is how do I get this trim piece off?

Is it just wedged between the cabinets and or glued?

Any 3M adhesive recommendations? I'm thinking 3M 80 for Rubber and Vinyl.

If it is like ours, looking from the end, it looks like a flattened letter C. The trim snaps over a metal track. Careful removing, as they have a tendency to break.

Winnebago may be different, but my ceiling trim strips look like this in cross-section. It is a t-molding that simple pressed into a slot.

I have found that I could take a peek at the end of one in my bathroom as it ends at the vent.

It is a flattened "C" which looks just like Mike's picture - for the plastic part. I was able to slide the bath one off and the retainer is screwed into the roof.

I found the plastic part on Amazon just in case I break it.

Any suggestions for removing it without breaking it?

Removing trim

Yes, it is like a calapesed "C". I took a piece if galvanized sheet metal (like heat duct) about 2" x 6 inches. On 1 end I bent about a 1/8" right angle.
I hooked this under the edge of the plastic and pulled it off. Once started the whole piece came off. Make sure it is warm in the coach and it will not crack
On a trip in 2011 the entire headliner started to come down. I ended up removing all the vinyl and the foam backing from the ceiling. I replaced the entire ceiling with an acustic carpet type material. Look on line under acustic material suppliers. Material comes 54 inches wide by any length, you can trim the width to 48 inches. The glue is 3M 90 spray glue.

Thanks, I decided to give it a quick fix. I used some shims and gave myself some room between the metal/plastic trim and luan, pushed the liner back in and shot 1" long narrow crown staples at an angle. They are hidden under the trim and holding the vinyl liner. Not perfect, but good enough for now until I decide on a permanent fix and have the time to do it.





When you did the acoustic carpet, did you pull the cabinets down too? That sounds like a big mess with all the sticky foam flying all over the place.

Ceiling headliner replacement

I did remove the kitchen cabinet, but cut around all others.
To remove the foam from the ceiling you need a sharp scraper and a drop cloth to protect the area your working in. I used a 5 in 1, it was about the right size and I stone sharpened it. Final cleaning of the ceiling was with the backside of an old piece of carpet. New material was purchased from Neil Gold at Goldman Acoustics in New York. They will furnish samples and have product shipped to you. I have some photos of the installation (If I can find them) Lwasouth

I'm not sure, but it seems that the scrapper that is attached to a dust pan like they sell for removing popcorn ceilings would work well.

Scraper

Popcorn ceiling is very soft and easy to remove. This foam/glue requires a sharp scraper and firm touch. Good luck.
