I’m redoing my basement and have three questions regarding the wallboard material I should use: 1) On the exterior walls (50% below/50% above grade) is there any benefit to using greenboard (i.e. moisture resistant drywall)? I don’t have any seepage issues and will use proper vapor barriers but am willing to use greenboard if there is any potential benefit. 2) Just in case I should ever get a few inches of water in the basement (e.g. failed sump pump) should I use cement board instead of drywall for the bottom 1 to 2 foot of the walls (I’m using steel studs and beadboard on the lower half of the walls)? If so, should I use foam panels to insulate the walls so it would dry out more easily (versus fiberglass)? Or is this all in vain (i.e. the walls would have to be torn open for even an inch or two of water)? 3) The basement stairwell is rather narrow and takes a lot of abuse (knicks, scrapes, gouges). It has knotty pine right now but I think just painting it will result cracks in the paint between the tongue and groove panels. So, is there a better, more durable material that can be used instead of drywall? I seem to recall hearing about something called Hardiboard and/or Homosote. Are these viable options to drywall in a high traffic/abuse area? Thanks in advance for your response! Ed

Hi, I started to refinish my basement framing went pretty well for as can be expected for a newbie DIY. I framed with treated 1x4's and started hanging the greenboard with the green side facing toward the foundation wall. Is this how I should hang it? as to most if any dampness, may come from the foundation wall... My question is should the greenside be facing the wall or facing me? sorry its stupid i know.
