* Do I nail into just the wall, or the wall and ceiling?
* Is there an standard spot on the moulding that you nail through, or do you nail "X" amount from each edge.
* I have 12 and 15 foot walls to cover. Should I attempt to install the moulding in one piece or can it be installed in two or more pieces (which would make the trip from the home center a lot easier.) If installed in multiple pieces, what type of joint should be used (I assume not a butt joint)?
* The moulding comes pre-primed. Would you suggest applying the finish coat prior to installation?
I appreciate your help.
