it isn't REALLY "waterproof". it's water resistant. You
gotta read the fine print.

Try titebond III - it's new, better than urethane and waterproof. it's the

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...)
