Replacing the tired old chipboard T&G sub in my galley kitchen and sistering a joist or two to level.
Are chipboard T&G joints always glued these days? Polyurethane or a wipe of Gorilla?
Thank you.

One side is rough, the other is smooth, with the brand name, batch No. printed on.
I've put up stud to enclose a new bath on 3 sides, time to put the Knauf boards on.
The obvs is that the rough face will grip the cls better.
So which face takes the tiles?
