With the tape-on versions, nailing is not required, so installation and corner alignment are easier, and there are no nails to pop when wood framing shrinks. They use the same paper-faced metal technology to provide excellent bond adhesion qualities for joint compounds, textures and paints. The unique green nose coating on the paper tape covering resists scuffing and fuzzing from knives and sanding. The paper tape covering ensures excellent adhesion of joint compounds, textures and paints for a strong, smooth finish.
