I've used Adkwik in the past. Airpress and Glued Direct can also supply UF glues. You will need to wear a close fitting dust mask whilst mixing the glue from powder
Are you aware that UF glue joints need to be bonded under pressure, so you will need quite a few sash cramps and home made cauls to do the job? The other thing is that technically, under current regs, relipping a fire door yourself voids the fire rating certification of the door (something we are now told repeatedly in the aftermath of Grenfell). I am surprised nobody mentioned that on a fire safety forum
