Mdf Glue Recommendation
What do yawl use when you do a 30% splice with MDF crown molding ? I usually nail a block behind the splice and use Elmer's wood glue..I'm not too sure the Elmer's bonds to the MDF like it does to real wood...
What's your thoughts ?

Hey! Hope all is well down 264! I prefer titebond II or III, but they're basic wood glue too. I'm sure it will work just as you need it to.

Titebond for me as well, but any carpenters glue will work with MDF.

I prefer construction adhesive on MDF but I seldom use MDF, it's from the devil.

Ha...I kinda like mdf. It's heavier than who knows what so I actually use it for most of my shop cabinets. Don't hate the player...hate the game.

The only point that I don't like about MDF molding, is the way the material blows-out (dimples) when shooting 15g -16g nails into it.
We only install it on specific jobs; multi-unit complexes that have it installed already in their units. We have to custom mill it (baseboard and crown molding) out of 1/2" MDF board, to match their custom milled mdf moldings (Not off the shelf stock). Other than that, I don't like to use it for molding, and prefer wood stock.

What I like about MDF is that its always straight, it flexes with bad walls and ceilings, no knots, and you can nail it within an inch of the edge and it will never split.
One time I was putting up some larger crown in a condo in Norfolk; did three rooms; on the last piece I installed, I shot was was gonna be my last nail, about 6 inches from the corner and SPLIT the trim..I was able to set a couple nails, glue the split and re-set it just like it never happened..Got lucky that time..I've been sold on MDF ever since.. I use a Dewalt nail gun and it sets the nails without dimples..
Thanx for the replies, I hope everyone is staying busy.....:)
