Need recommendation for a good mastic glue

[Mark Gibney]

I am looking for a good mastic trowel-on glue to attach wood boards about 5" wide, to plywood. This is to make "barn" style doors, they will be using inside a home, so there will be no rain / sun to deal with.
I will secure the boards with a 23 gauge pin gun too.

thanks, Mark

This stuff is available at a Big Box store near me. Has anyone tried it?

PL premium would work.

Is there going to be a problem here with wood movement?

[Steve Rozmiarek]

I've used PL400 for that very thing, worked fine.

Thanks for your suggestions on using PL adhesive.
Matt, there should be minimal issues around wood movement. However, I have quite a bit to do so I'm looking for a gallon mastic at least, not tubes.

I think this might work. The specifications say it allows for wood movement, never a bad thing.

I don't understand going to the trouble to trowel it on. One of the PL's comes in clear. I'd use that, and the large caulking tube size if you already have a gun for that size, or the regular size. The adhesive doesn't have to cover the whole backs of the boards.
