Best glue to repair this break?

Many thanks!


Titebond will work fine.
Optional: add dowels for joint strength.
Nix on biscuits or pocket screws as you will likely destroy more of the MDF.

So apparently you have not repaired MDF with biscuits or pocket hole screws. You might give it a
try some time, you will probably be surprised.

Experience has shown that biscuits in MDF have a tendency to initiate splitting
along the center of the panel. Also screws promote disintegration in
the local area of the panel.

I have used pocket hole screws to connect MDF and Domino's to reinforce
MDF unions. It is strong union.



Did you not notice the word "optional" used with
the dowel recommendation?

Yes I saw optional dowels along with Nix My tested suggestion.
