Taping angles > 90 degrees

In order to conserve space around my furnance and hot water heater, I chose to build my walls with a tapered angle (versus a rectangle). It saved a considerable amount of space and opened up the room. However, I have a question regarding the final taping.

Normally, on a 90 degree angled outside corner, I would install cornerbead. Do I use the same cornerbead for angles greater than 90 degrees and just "open" it to shape? Or is there special bead that is a bit more flexible that will easily conform to the custom angle?

Take a look at the link below, there are various bead and trim accessories available at Home Depot, Lowes that will help in what you are doing.


Hope this helps!

You can just use your regular tape and bend it around the corner if you like. It works just fine.

My two cents.

When doing 135 degree outside corners, I just take regular corner bead and spread it out. Put the corner bead on the floor and push down on it with a fat piece of PVC pipe. Depending on how you framed the wall, you may want to use the tape-on corner bead rather than the nail-on because there may not be great places to nail. You can do this with either the regular or bullnose corner bead.

I noticed in the PDF file that Doug supplied, USG does sell a 135 degree corner bead (see page 22 of the PDF file).
