i don't see why not. it will be there when the wood is gone. i've been using it on transoms, put it down and run a slotted trowel thru it, so it will spread, the lay the deck, use screws on a lot of weight.
I'm going to glue my deck down with PL. Cheaper than epoxy. I will also be filleting and glassing the top with epoxy, so either way it'll be verry strong.
