Drywall contact with concrete foundation wall

[Mainiac Mat]

I'm hanging the rock on my garage walls tomorrow and am wondering if I need to space it off the concrete foundation (frost wall)....

or can I just rest it on the concrete and screw it home to the studs?

moisture wicking up through the concrete would be the concern... not sure whether it's necessary to make allowance for that or not.

Yes, space it about 3/8 to 1/2 inch off the concrete.

Just cut a couple wood spacers of the appropriate thickness to use when installing it.

I'd use a plastic j-channel on the bottom. Makes for a nice finished edge.

Exactly! and stops water from wicking...

I’d use green board for any areas that you are concerned with moisture. We never use regular drywall in moisture prone areas

I have the same condition in my garage. We left the drywall just 1/4" above the top of the stem wall to prevent moisture wicking and concealed the crack with pvc quarter round.

Thanks for the replies... I couldn't get J channel so I went with 1/4" shims and left an air gap.
