I am redoing my bathroom, and am wondering am I able to install new drywall “greenboard” over the old wall material that is there? The room has evidently been done numerous times in the past. The existing material is what appears to be a plastic type wall covering about 1/8” thick, similar to what you would find in the shower area of a very old mobile home, over top of 1/8” thick smooth paneling. I am removing the first layer, and I was going to go down to the studs, but then I have the blown in insulation falling out. Looking at the GP web site, it states, “Old wall material must be perforated sufficiently to prevent a double moisture barrier”. Am I going to run into problems if I do not remove both layers of wall material?

If I were you I'd remove the existing. If moisture gets trapped between that and the layer your adding it can create more problems than it's worth. Plus you want to make sure you get good contact if you are tiling.

When you do take off the existing do one wall at a time & place 6 mil poly stapling it up in sections and working with the blown that way. It will be less of a problem it should only be in the exterior walls at any rate. You need the vapor barrier in those locations anyway,(unless you're in the deep south then use landscape cloth). It's the interior walls that really need to breath, the exterior you want to protect from the flucuations in temperature creating moisture at the dew point.

See if you can get into the attic and move the blown from the ceiling, you can put it back when you're done. Wear a good respirator up there. That needs a vapor barrier as well.
