adhesive for wall sheathing on houseboat?11/16
I'm building out a mini houseboat on a 26ft JC Craft Tritoon. stick frame construction/OSB T-111 siding, interior walls are 1/4" shop ply laminated with FRP Panels (I have "Green Choice" FRP adhesive made by Franklin/Titebond for the FRP skinning, but can exchange for another FRP adhesive if anyone has any opinions or experiences to share that might suggest doing so...)
James, I think I would use some sort of flexible marine type adhesive which you can get in a caulking tube, like a polyurethane.
With that much power and speed, there will be lots of flexing of hull, which would destroy mechanical fasteners eventually.
You can certainly find what you need at West Marine or other boating supply, but I have been seeing some of those adhesive/caulks showing up in the hardware lumber yards at pretty reasonable prices lately from good brands like Locktite.
This is not rocket science and your weldwood brown is fine. If you're really worried over flex than go with Franklin type ll or lll. Personally I wouldn't allow or permit any flex between sandwiched layers of wall sheathing (why create squeaks). Liquid Nails and other flexible adhesives will positively let loose.
Hard setting resorcinol was the glue of choice for boat and plane builders since WW ll but now it seems to be epoxy. The Spruce Goose, British Mosquito Bomber, American PT boats, minesweepers and thousands of LLC boats (to name a few) all glued and screwed with resorcinol.
