I have a room with high cathedral ceilings and two rows of windows. There is currently tongue in groove pine strips about three quarter inch thick on walls. i want to sheetrock over this material without ripping it out. My problem is the moulding around each of 20 windows that are recessed. Can I install sheetrock over pine strips and abutting against moulding? If I do the moulding will still protrude approx one eighth inch beyond the sheetrock. If the sheetrock is installed so that the straight edge abuts the moulding with perhaps a bead of thin caulk on top (against the moulding) can I get a finished product that looks decent?
