gluing MDF

[Swaglosrevival]

Hey guys.

It might be a stupid question, but I'm new to Furniture making and want to build a bookshelf out of Mdf using pocket screws. I want to use titebond 2 to glue the joint before screwing it, but I've never glued Mdf. Can I use normal wood glue on Mdf or should I use something else?

if your using a kreg pocket screw set up ya probably don't need to glue it however if you still want to I suggest gorilla wood glue.....MDF usually don't like glue because it is very porous but you should be ok for a book shelf.......apply a very thin coat on both sides of connection and let sit 10 or so minutes then apply again just before you screw it tight wipe off any extra....

Mark sure that you use screws made for MDF. Dry wall screws could pull out under the weight of the books.

Ok but doesn't gorilla glue foam up? I guess if I clamp it up tight.

Yes, MDF loves to soak up the glue.  Be careful when putting the pocket screws in mdf and do not over tighten.

Yeah those pocket screws will pull through anything. I used some on 2x6 pt, and over tightened. It ripped right through the wood.

Mdf changes country to country tho..

The regular gorilla glue foams up? The key to it is to NOT wipe it immediately. Let it foam out and AFTER its dry, snap the foam off or trim it with the appropriate tool.
