I'm building a relatively light weight redwood garden gate. The corners will be joined with glued 1/2 lap joints. I'd like to use a glue that will stand up to weather and will not sag. Recommendations please. Thank you.
I glued a repair in some stairs that went down to river. They get flooded occasionally and are always exposed to weather. Used Gorilla urethane glue. It outlasted the wood.
If design isn't your strong suit, maybe giving a bit more info might be helpful. Are there any triangles to brace the swing side, and how wide and tall will the gate be. There are limits to what you might expect any glue to handle if you exceed what that, especially on a relatively weak wood like redwood. Even if the glue hold, it can tear wood fiber out of the face of one or both faces.
I hate urethane (Gorilla) glue, but it's perfect for this application. I built my wife a potting bench 8 years ago. It lives outside and it's still as sturdy as the day I built it. I used lap joints, stainless steel screws and polyurethane glue.
