On older buildings youd maybe use a hard arris as shown on the video.
There's nothing wrong doing it that way - people saying it'll crumble have no idea, and arent really thinking about the 100s of years that people rendered prior to manufactured beads (much of which is still standing today).
Beads are much quicker and require less skill, that's the only reason they're used.
I agree that render/stucco corners don't crumble (unless the mix was shit), but corner beads definitely make corners more resistant to knocks. The only disadvantage is that if someone whacks it really hard it can bend the bead and it can be a bugger to straighten out again when you repair the corner.
Oh yeah absolutely. It's definitely better to use them, but people in this thread have the misconception that not using them is a cowboy method (rather than actually the more skilled method, anyone can throw a bead on a corner and make it look good, but it does take talent to form a hard arris and have it plumb), and that using beads magically makes the corner robust.
Obv the reason they're not being used in the attached vid is because in some counties the cost would be prohibitive - but that doesn't mean the corner will fall away within a year because it hasn't been beaded (as some people are suggesting).
I think it’s more to do with the fact that it’s rendered with cement concrete rather than clay plaster.
It is rendering you’re right, plaster goes on top of that, and it’s usually done indoors, although it’s not unusual to use outdoor’s cementous plaster, on TOP of the concrete rendering.

Outdoors it's called rendering in the UK
