I need to lay a double layer of 1/2 inch sheetrock to prevent some plumbing pipes from protruding out too far from the wall. I know I need to do the ceilling first, but my question is do you think it would be a problem if i put up the first wall layer then the ceiling and then the second layer on the wall. (only because I need help from a friend lifting the ceiling in one piece which I cant get for a day or so). Also aside from being careful not to hit screws are there any precautions i need to take when applinging 2 layers?

 

sounds like way too much work and expense to do
2 layers of sheetrock. i would rather get a sheet
of plywood and cut 1 1/2" furring strips out of
that. one sheet of plywood will fur out 30 studs.

 

I would fur the wall out as well. You can get pre cut 1x2's. But if you want to hang 2 layers go ahead and do the wall first then ceiling then wall.
