In my 60yo house, I have a few basement walls that are plaster over lath (and several unfinished walls, which i plan to frame/drywall). the surface of the plaster is very rough, presumably done on purpose some time ago (any ideas why?), and slightly cracked.
Since i'm dry walling other walls, i figured i would just lay drywall over the plaster rather than learn the art of plaster repair. Any reason i shouldn't do this?
Slightly more odd question. I want to mount speakers and lay speaker wire across this wall. i know i will have to cut the plaster/lath for the speakers which is fine. for the speaker wire, any thoughts on just routing a shallow groove on the back of the drywall to run the wires? will this make the drywall too fragile? not sure if this is the equivalent of scoring the drywall and hence cause a disaster. now that i type this, it occurs to me that i could also route the plaster, and hence leave the drywall intact. would that work?
