I’m trying to find a water-based glue to adhere 45 degree miter joints
with a biscuit at each joint. I feel I need a water based glue to swell the biscuit but also require a relatively long open time to allow me to
properly assemble and align each joint. The piece is a 4’long by
2′ wide walnut frame to encase a glass table top. Each length of board is 2″ thick. I’ve built 4 wooden jigs to assemble each corner joint and am in a position to work quite quickly but feel most pva glues wood set up too fast. Any recommendations?

PVA glue sets up too fast?? In the windsor chair glue up phase, you are a@#$$ and elbows sometimes in a rush to get all the pieces in place before the glue sets up. Many of my fellow chairmakers have gone to Elmers white glue after some frustrations with the faster setting yellow glues. I have tried the white and it does set up slower. It gives me plenty of time to set up and adjust unlike the yellows. So it is an option for you if you need time. Additionally, there's plenty of water in the white glue. Best of luck. Remember, if it doesn't work for you, you can donate the glue to the local grade school- they're always short.
Hi Doug,
A yellow glue such as Elmers or Titebond will do fine for this task, but the short open time (about 5 minutes) requires that you work quickly. But if you practice with a dry assembly and get all of your clamps set up ahead of time, you should have enough time to get all the miters assembled.
Alternatively, epoxy will give you a long open time and a strong assembly. I'm not sure if epoxy will swell the biscuits or just fill the gaps; however, either seems appropriate.
For a more thorough overview of glue options, this article is a must read.
