How to Apply Drywall Corner Bead?

I bought some vinyl drywall corner bead and was wondering how to apply it.

Do I nail it? Plaster under and over it or just over?
A thin layer of joint compound is put down first. Then the corner bead is pressed into place. More joint compound is spread over the top, and feathered out from the corner.
I guess vinyl is different, but the metal stuff in Vegas is nailed or stapled and then textured over.
I’m kinda waiting to hear how this turns out, as I’ve always nailed vinyl beading. The metal beading I set with a clinching tool and rubber mallet, and the vinyl with preattached paper is the only stuff I install with mud alone.

Agreed… I assumed all vinyl corner bead was paper bound. Is this not the case?

Let me restate… all paper bound corner bead (no matter the structural material) are affixed in the above stated manner.
I had the vinyl bead with out the paper, used a few nails then mud. Sanded it down and its a perfect corner now. Worked great.

No-you can buy vinyl which looks just like metal, except it’s (not to be a wiseass) vinyl.

I have used for many years, and it’s great. For preformed archways, , in their architectural division has a number of offerings, too.
They make a special spray adhesive for the Vinyl bead. Don’t fucking try to just put joint compound under it like you would do with a paper/metal piece or it’s just gonna pop up.
