Paperbead for protecting drywall corners

摘要

An improved corner bead (1) for drywall construction having a paper layer (4) bonded to an exterior surface of a formed metal or plastic core (3). The paper (4) is impregnated with a latex prior to affixing it to the core. The uniformly impregnated paper (4) provides improved protection against adverse abrasion at all levels of thickness of the paper (4). An improved method for covering joints formed between abutting sheets of drywall (8) involves spreading a bonding layer (10) of joint compound, embedding the paper strip (4) in that compound, applying an exterior layer (12) of compound, and sanding the exterior layer (12) so as to provide a smooth and continuous surface between the drywall sheets (8).
