Delamination area to watch for.

[ddev]

I am constantly watching the problem areas around the windows etc for signs of Delamination and found a new one today that could have easily been avoided... A small area below the access cover for the fridge opened up. When I pulled the cover frame off I found the builder left the cut out opening in the wall unsealed and did not extend the water drain from the fridge outside the compartment, so every time the fridge melts off the ice/ frost accumulation from the evaporator in the fridge, it would end up draining down and sitting next to the cover to be absorbed into the luan under the fiberglass outer wall. I'll extend the drain out a little so it will hang out the top row of louvres slightly.
I have had pretty good luck using Git Rot to repair the water damage to the sub surface plywood, but it wicks so far back into the wood I need to go back and glue it again after it has cured to get the surfaces to bond together. A few pictures to show the offending drain. The fridge is a Domestic, not sure how the Nor cold is set up. Having problems with pictures at the moment I'll add when I can.

my norcold has a small rubber drain hose that is pinched almost closed at the end. the end sits in a metal cup and drips into there, where it evaporates. the bottom of the area exposed by the removable panel has its own drain to the bottom of the rv.

I found a product called Compset SLV epoxy that works welll for delamination repair. It is a little thicker than rit rot, but still flows very easy.

Thanks for the info, I'll have to pick some of that up for future use... I ended up using Gorilla glue, tough stuff to keep clamped securely as it expands so much but it does a good job if you can.

Gorilla glue is pretty good stuff. It's polyurethane, and cures when exposed to moisture (super glue and silicone are also moisture-cure adhesives).

That is one reason Gorilla Glue expands, the more moisture available, the more expasnion, otherwise known as "foaming". It's a little thick for deep penertration. But once it bonds it is very strong and flexible.
