Hi y’all,
My partner and I recently started building fireplace mantels on the side. They are 90% MDF with a little bit of trim.
As of today we are using plain yellow wood glue and shooting them together, but a few people have told us that we should be using a special type of MDF glue.
The yellow glue seems to be working fine, as far as we can tell… we sure would appreciate anyone’s word’s of wisdom or prior experience.

Yellow glue has worked for me, but all my applications were interior. You generally are not using MDF where moisture is a problem, for an 'ordinary' glue should not be a problem, either.
I'm not sure I'd want to scrape the excess from a 'gorilla' type glue and risk dinging the mdf. But, that's me.
I have also been using yellow carpenters glue on MDF since I first ran into the stuff. Seems to work fine but I have found the thicker ( higher viscosity) yellow carpenters glues like LePages and Elmers Probond don't swell the joints like the thinner and usually cheaper glues.
Also I have had better results if I wait for the glue to dry before sanding outside miters. MDF just falls apart if you try and sand it wet.
Yellow glue works just fine. I use Titebond.

Same as everybody else, yellow glue. Try taking some of the stuff apart after the glue sets, bet ya cant do it without tearing the sheet out of the MDF!
