Tape and fill external corners

[cwr]

Hi folks

Any advice on best method of doing external plasterboarded  corners with tape/fill/sand?

I've used paper tape before and the results were aesthetically good, but was very susceptible to chipping. 

Is the paper tape with a metal film good, or is there a more robust solution out there (that's not wet plastering)?

Thanks

If it's a location that might be susceptible to wear, I'd look at an extruded metal bead.

I have just done a small bit with the metal reinforced paper tape on some boxing.  It was not too bad.  If I was doing it on price we would be hungry!

Plastic beads, the only proper way to get a sharp external corner IMHO

Why plastic rather than metal?

I have only seen them used for external render.  The OP is doing tape and fill plasterboard.

Metal reinforced tapes are good, nice true and straight corners, and difficult to damage.

Used these on my plant room, and happy with them to use again, would also consider using them for a vaulted ceiling to wall internal corner on my next room. It’s also dependent on the fill you do, how many fills and how many sands.

Corner tapes this is what our taper insisted on for our vaulted ceiling (nearly all of the rooms). Myself and grandson did the hall and it was great to use.

They don’t dent, they get bashed, the plaster pops off, you can then re fill the damaged area without changing the whole bead.

Available in thin coat for internal tape n fill, widely used in America and Australia where they tape n fill far more than us 

they do a massive amount of decorative beads including shadow gap and ones that take led strip. 
we are a bit stuck in 1960.

Can you get ones for fill and sand? I've seen some at 2 or 3 mm but surely they're for wet plater as would stick out too far? Unless possibly along the tapered edge but I can't always arrange that.

That's an unusual octagonal access hatch...

Yes a bit odd.  It is fire and acoustic rated.  Maybe the octagon made it a bit stronger?
