    Drywall for corner greater/less than 90 degrees.
    Any tips for hanging and finishing drywall on a corner that is not 90 degrees. There are two places where I will have greater than 90 degrees (approximately 135) for inside and outside corners. Is there a special corner bead strip or can I use regular corner bead and bend it? Thanks in advance for the help/advice!!

    Inside corners do not get a bead, use paper or fiber glass tape, preferably the later. Outside corners can be beaded with vinyl bead.

    The outside corner can be done with a metal corner bead they make a 135 bead and the inside corner should be taped with paper tape and joint compound

    There is a paper tape made for outside corners that are larger than 90 degrees. It has 2 lines of aluminum running the length with a pre creased line in the middle.

    When installing the S/R, try to make a good outside corner. Use utility knife or surf planer on edge.

    Certainly no expert here, but have seen pros cut the back paper either and break the rock leaving the face paper intact, for inside corners, and gouge out some rock for outside corners.

    They made the crease in the face paper perfect and eliminated taping these joints.

    If you can't figure out how to do the inside corner there is a few products out there to do it 1 is called straight flex and another is no coat these products are not real cheap I have also seen straight flex used on outside corners do not use the tape with the metal glued to it it is more work than any thing
