Yes. My application was exterior.
Yes. I am using it exactly for that
Hi Jack, we do not offer the 10 ft. Vinyl Corner Bead in a larger width on Homedepot.com. Thanks for shopping Home Depot!
The 10' vinyl corner bead is for outside corners only.
U can 'mud' it in by setting the corner bead in a strip of mud that has been applied along the corner edge. (Do a dry layout prior so u can measure, cut to fit bead to proper length) I actually used a construction adhesive as I was doing an exterior application around re entry installed sliders and I was stucco-ing around frames. U can use a pneumatic or hand held staple gun also to attach to framing material.
White, but I believe it's intended to be covered with join compound and then painted.
