A few days ago I glued together 2 pieces of well dried 4x6 timbers to use as a header over a doorway in a building I'm working on. I used Gorilla wood glue for this and it was well cured. Then last night we had a heavy rain and the excess glue that came out of the joint turned white and softened a lot. This glue is advertised as indoor/outdoor but I would say it's indoor only. Now I'm going to have to cover the header with plastic until I can get a roof on.
