ABSTRACT:
A wall construction comprises a ceiling or wall structure having an exposed surface, a drywall panel having an edge near such surface, and an accessory comprising a bead for finishing the edge and a separate, removable strip for masking a portion of such surface to prevent drywall finishing material or paint from being deposited on the masked portion. The bead has a generally L-shaped profile with a surface-engaging leg secured to and engaged with a panel surface, with an edge-covering leg extended inwardly over the panel edge, and with a generally U-shaped lip joining the legs. A generally J-shaped portion of the edge-covering leg defines a channel opening toward the lip, grasping an inner portion of the strip releasably, and having an edge spaced inwardly from the lip. An outer portion of the strip extends beyond the lip and performs such masking function.
