Abstract
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.
