Interesting exchange in a Facebook group called "Our Old House" which is mainly about people doing up "old" (seems to be 1980 or earlier) houses, many of which I think we would refer to as sheds as they are wooden structures.
Question
Advice on drywall for not plum, old true 2x4? The plaster not salvageable. Do I need to sister 2x4 everywhere? Can I just shim them? Nothing is plum including ceiling. Appreciate any advice, my expertise has nothing to do with this, and reputable carpenters are few and far between here.
Answer
Depends on how straight you want and your skill set. Sistering is faster and easier but shimming uses a lot less material
Makes nonsense of the suggestion that Americans speak English.
