I'm betting this can't last long...too wet an environment, too much
temperature swing.
Please report how it works.

I want to glue some PT boards together to make a deck for a swim platform
and have them very waterproof. Will biscuits swell properly with urethane
glue?
I have a large bottle of TitebondII, but don't think it is sufficiently
waterproof for this application.

(If not, maybe I will try that glue-joint router bit I have never used...)
