CEMCO’s CEMCORNER is used as an exterior corner reinforcement that has a nailing strip along both sides for faster installation and straighter corners. CEMCORNER was designed so that it is easier for Portland cement plaster to flow into the nose of the CEMCORNER. CEMCORNER is available in standard straight, straight arch, bullnose, bullnose arch, and a special bullnose-shortflange to accommodate almost every conceivable corner application.
