I'm about to start on finishing our basement and I'm going to put down a subfloor of DMX AG along with 5/8" T&G OSB. Should I frame out my perimeter foundation walls before the subfloor or after? If I install them before, the 1/4" DMX gap will allow for any potential moisture to evaporate into the room. If I install the foundation walls after (and on top of) the subfloor, any potential moisture would evaporate between the wall and the foundation. Which is better?
Our house was built in 2016 and is a walkout with no water issues in the 2 years we've been there so far.
