You mean what's called 'engineering fibers'? Dunno. With a good FC
armature of close-knit mesh (of whatever kind) I don't know that they'd
add much. Don't know how they'd affect the 'trowelability' of the
material either.

So wouldn't expanded metal lath have the same issues? It's a galvanized
metal product...?
