Reinforce exterior corner 135 degrees?

[catherineb]

Hello!

I'm considering the best way to reinforce an outside corner on drywall that's 135 degrees. There are no beveled edges in these corners. I've used fiberglass tape on the other seams and plastic corner beads on the 90-degree corners.

Can you use fiberglass tape or maybe paper tape? Or just go crazy with joint compound? How have others done it?

Hi!

I'm wondering how to best reinforce an outer corner on drywall that is 135 degrees. There are no beveled edges on these corners. I've used fiberglass tape on other joints and plastic corner beads on 90-degree corners.

Can one use fiberglass tape or maybe paper tape? Or just plaster a lot? How have you others done it?

The best joints in our house are indeed those 135-degree ones... they are paper taped, plastered, and painted.
But if you want nice corners even in five years, you put a trim on the outside.

I have used this in a 90° corner, but it is quite flexible so it should work for 135° as well.

I have used this, although at 90° corners, but it is quite flexible, so it should work for 135°

Similar list I have used.

Works on both inner and outer corners.

Perfect, that's exactly what I'm looking for!
