Ya know, it's interesting...
I'm getting closer to carpeting. I've bought the carpet. I've bought carpet pad. (There's that silk purse again, LOL!) Now the pad is from a boat carpet "e-tailer" and, it's approved for double glue down: i.e. glue the pad down, glue the carpet to the pad. Great, right?
Well, it's a polyurethane padding. Will a solvent based adhesive eat it up? Hmmm...
Most solvent based adhesives say not to use it on painted or protected (say, coated with "old timers" boat wood finish) surfaces, because it will eat the protection. Most water based adhesives for marine use (once it's dry, water won't cause it to come unglued), say that if the adhesive doesn't soak into the wood a bit... it won't stick well.
So, this means I have to leave the carpeted side of the plywood untreated. Whichever way I glue the carpet down on it.
That does not please me. Wood rots. It rots slower if protected. Carpet holds moisture, a perfect environment to accelerate rotting.
Aluminum decking is great, but it adds weight without flotation, requiring offset auxiliary flotation.
To heck with it! Full steam ahead!
Plywood!
It'll probably last until the boat is part of my estate, anyway.
Worrying ain't getting the boat built! But it's raining, anyway.
