Fastening drywall directly to concrete?

I've just finished framing out my interior and outside walls and getting ready to fireblock it all soon. And as I think about eventually sheetrocking, I do have one wall that I may need to place the sheetrock directly to the poured concrete wall and open to any suggestions.

This last wall is the one that is sort of a 'inside' concrete wall where my steps leading down the basement runs up against and butts up next to/below my garage. So it is not actually an outside wall exposed to the elements.

The main issue is that I have a 1 1/2 inches from side of the steps to the wall I could maybe get furring strips into the concrete, but may still have issues in potentially exceeding 1 1/2 and overhanging the side of step.

Since this is sorta of an inside wall, can you glue direct to the concrete?

It's not a good idea! Concrete absorbs moisture and could cause issues with the drywall. I'd at least want to fur it out 3/4"

The problem is there is no glue out there that will grab a hold of a heavy sheet of drywall without some mechanical fastening.

You should do the firing strips.

Since you have 1 1/2", I would probably glue sheets of 1/2" XPS to the concrete, followed by 1/2" x 1 1/2" plywood strips 16" on center on top of that (it won't be directly on the concrete that way), and then glue 14 1/2" rips of 1/2" XPS foam between the plywood strips. Gives you mostly 1" of insulation that way. Should give you 1/2" to install drywall. Use 3/8" rock if you have to.

Thanks for the quick response and was answer I was expecting as well.

So I'll likely being added a few PT furring strips to that wall when I'm ready.
