Need Suggestions for Wall/Wallpaper Repair on Damaged Rear Wall

[bobinyelm]

I have a 2007 Wildcat RV with an aluminum frame with laminated Fiberglass (Filon) siding outside and luan w/ vinyl wallpaper on the inside.

My LR corner caulk got a hairline crack and let moisture in and got away from me until I saw delamination.

I opened up the corner, dried it out, and shot "Great Stuff" foam in the sidewall and installed new structural wood in the corner and secured it to the aluminum frame as it was at the factory. The side wall feels and looks good now.

Unfortunately the rear wall is Filon over a "framed" structure with fiberglass bat insulation in the middle, and an interior "wall" of luan with wallpaper on the interior side.

The luan on the interior of the back wall next to the wall panel has deteriorated, leaving intact the wallpaper with no "hard-board" luan behind it, making a 1ft X 2ft section of the rear wall at the corner soft (w/out panel board support behind it).

I am not going to completely remove/disassemble the rear wall and build a new wall because the structural integrity of the overall back wall seems sufficient to me to be perfectly safe.

My plan is to fabricate a new interior wall panel that will cover the entire rear wall surface (that is not occupied by cabinets and windows) with a new single piece of thin luan covered by a matching or complementing piece of vinyl wallpaper. I plan to secure the panel to the rear wall framing with sheet metal screws or the like. This should make the "soft" section acceptably rigid, and be functionally almost as good as new, and will appear "normal."

Where does one source such wallpaper, and overall, does the plan sound doable? If not, I am open to any suggestions as an alternate plan.

Thanks,
Bob

I am looking for wallpaper now for my 2006 Seabreeze. Wall ok but wallpaper ruined

I just looked at HomeDepot and they have various panels I could possibly use like beadboard, FRP (fiberglass reinforced panel 0.09 thick) rather than wallpaper, but no appropriately close wallpaper to apply to luan.

Go into one of your cabinets, behind the drawers, etc., carefully cut and peel off some wallpaper and replace the bad spot with it. If the wallpaper-removed Lauan needs some protection, paint it.

New sheets of Lauan available at Home Depot, Lowes and so on. Of course it doesn't have wall paper on it.

This isn't wallpaper but a thermoplastic decorative panel that might work for you. We just used it in our bathroom to cover some holes made when we rebuilt the medicine cabinet. Adds little to no weight, is easy to work with, comes in a number of finishes and designs, and applies with adhesive. We used brush nickel hammered.

We found a masonite panel at Home Depot that is virtually identical to the original finish, and that while it is not plywood, matched in every other aspect.

Unfortunately, it's not water tolerant, of course.

Don't remove the old lauan panel, just fill the bad spot with an identical thickness patch. Where necessary, the patch can be held in place, flush with the rest of the panel with small tabs glued on the back side of the existing panel. After the patch is done, glue full sheets of new paneling on top of the existing paneling. Use construction adhesive like Power Grab, Instant Grab from Lowes. Intended for use in bathrooms and it dries clear. Maybe you can find pre-finished paneling you like, if not, then go to a wallpaper shop.

Unfortunately, the damage extended to the framing, so the work went far deeper than skin-deep.

I ended up rebuilding a lot of structure.

Fill, sand, paint. Thats how a lot of folks handled similar situations

[bobinyelm]

Cut, remove, re-fit, and rebuild, really.
I wanted it good (and structurally) like new.
Stick built RVs are sensitive to moisture.
