I have an area under the bedroom window that I'm considering doing this to. The window seal leaked for years (prior owner). I fixed the leak but I'm considering pouring an viscous epoxy down the wall through the window opening (Delamination Repair, RV's, boats, wood). The luan appears to be intact, just delaminated from the fiberglass well.
I've seen several posts from folks saying that someone they know did this but can't seem to find anyone that has actually done it themselves.
I have done a few delamination repairs on my rigs.
In the worst case I had to remove a large section of 2x2 wood framing around a window, as well as a section of luan/foam/paneling below the window. I left the Filon intact. After removing the bad material I worked the flowable epoxy from Composet into the edges and the bottom where the original materials remained. Then I added new luan, foam, framing, and paneling layer-by-layer bonding it together with PL Supreme urethane adhesive, and epoxy.
Under 2 other windows, where the framing was good and the delamination was smaller, I just used the flowable epoxy to bond the deteriorated luan back together, as well as bond the luan to the foam board. This worked well with the exception of getting some debris (probably luan particles) trapped in the area and resulted in small bumps in the Filon surface.
Figuring out my plan of attack took some effort, then finding the materials took multiple trips to the shed and Home Depot, finally you will have to rig up clamps and jigs.
Unfortunately, once damage is done, it will never be the same as it came from the factory. For me budget was a key factor. Having a shop tear it apart and rebuild it was out of the question. If you are handy with tools, have access to various materials, and understand a few things about glue, then DIY may be the answer.
