Question. How does one build a sheetrock box with out a wooden frame? Or are we all supposed to be masters of some specialized trades and that is a stupid question? Only Llort knows.
I think I heard somewhere that you could build things and hold them together with a wondrous material called ...glue, I think it was.
My house builder stuck some sheetrock to a concrete wall with "Liquid Nails" about four years ago. Still there.
