inside corner bead

[Electric Comet]

have not ever used an inside corner bead and decided to try them

i see plastic ones and there are metal ones

any pros or cons for either type

[Ed Pawlowski]

Yes, for both.

went with the metal as it seems to me the mud will adhere better to metal than the plastic

[John McGaw]

I try to never use mud in my woodworking. Even my _worst_ joints are tight enough that it is not needed.

[Electric Comet]

one possible con against the metal bead is that it can rust if in a moisture prone environment

hopefully paint would prevent that and probably not a factor here

but one possible downside for metal

[Electric Comet]

looking more closely at this corner bead i am starting to think it is galvanized

guessing that it is hot dipped galvanized

i do recall seeing rusted corner bead but it may have been an old installation

I've seen a fair bit of rusted corner bead - when in a damp area with no paint. The stuff is lightly galvanized - there are also blastic corner beads that won't rust - - -
