By far the most frustrating thing about plastering jobs is the drying times. This is especially true with inside corners - with a knife you pretty much can’t do both sides the same day because you’ll always end up messing up the opposite one.
I finally gave one of those corner tools a try, and the result is fucking mint. The customer is going to be so happy with these flawless corners tucked behind the curtains in their living room.
Plumbing is way, way easier than drywall (in fact I would go so far as to call the supply side of it “easy,” including soldering copper pipes); it’s just that the penalty for failure is so much higher.
I partly agree and partly don’t.
Plumbing as a field is way broader than installing drywall, and there’s a ton to learn. No single plumbing task is really harder than hanging drywall (except maybe welding), but doing all the drywall in an entire building is a hell of a lot easier than doing all the plumbing for it.
I’m only talking about DIY plumbing a single-family house, and I only said the supply side was easier. The drain side is more complicated to understand, with the slopes and venting and whatnot.
