Cloth ceiling repair

[Bucky1320]

I have a 1999 Harney with what appears to be cloth or even carpet type ceiling. As expected, there are many smaller areas where the adhesive is failing, and there is a bit of sag here and there. I don't see any roof issues or signs of any water damage. Just many little areas of this sag.
Any tricks to getting the ceiling back into shape? These look like 5" round pimples more or less.

I am sure the foam comment is correct. I looked more closely at ours, and I see stains here and there. Figured out what it was: Adhesive. Last owner must have done some fixing with adhesive and in places it bled through.

Don't know about your harney, but some coaches had foam backing on the ceiling material. As the material aged the foam dried out broke down and came loose from the ceiling.if that is what is happening to yours I doubt you will have much luck reglueingit and make it look like it used to. I know some who put wood strip across the material to hold it up, but depends on material and how and why it is letting go.

Great suggestions! I will see if I can find a needle/siringe that I can use for injecting. And also will see if staples hide decent in this material. I will report back when I get a chance to compete it.

A contact cement (or other adhesive) rated for automotive headliners should do the trick pretty well. Getting a good bond without removing the entire section of cloth might be a tricky operation with many adhesives; you ideally want/need it spread over the whole loose area.

If there's somewhat of a nap on the material, you might have decent success simply stapling it back in place with a standard (T-50) staple gun. The staples should hold it up regardless; the nap simply helps them to disappear from view.

Use a compatible glue that is injected behind the fabric with a syringe. Then just push the fabric in to place and hold it there until the glue has set up. Be careful not to use too much adhesive.
