The paper tape covering ensures excellent adhesion of joint compounds, textures, and paints, delivering a strong, smooth finish. The bead is manufactured with strong, paper tape that is laminated to a sturdy, rust-resistant metal form. It provides superior resistance to edge cracking and chipping, resulting in corners that stay beautiful despite normal building movement and everyday wear-and-tear. The bead installs quickly and easily with a unique paper tape nose coating that resists scuffing and fuzzing from knives and sanding.
