The present invention relates to drywall corner beads, particularly
drywall corner beads having an outer paper layer, and paper therefor. The
improved paperbead includes an elongated core having an outer surface. A
paper strip is bonded to the outer surface of the core. The paper is
impregnated on one side with a polymer, preferably latex, that penetrates
only about half the thickness of the paper. The other side of the paper
is roughened to improve adhesiveness to joint compounds. The latex
impregnated side of the paper maintains increased strength making the
paper resistant to scuffing while at the same time, the roughened side of
the paper improves its adhesiveness to joint compounds.
