Abstract:
A drywall-trimming assembly comprising a drywall edge-trimming strip extruded from a first polymer, a drywall corner-trimming device molded from a second polymer, the drywall corner-trimming device having a projecting tab adapted to fit under an end portion of the drywall edge-trimming strip so that an outer surface of the projecting tab faces an inner surface of the end portion of the drywall edge-trimming strip, and an adhesive of a type that adheres less strongly to a unit of surface area of the outer portion of the projecting tab and that adheres more strongly to a unit of surface area of the inner surface of the end portion of the drywall edge-trimming strip, the adhesive constituting means for adhering the outer surface of the projecting tab to the inner surface of the end portion of the drywall edge-trimming strip, wherein the inner surface of the end portion of the drywall edge-trimming strip is smooth on a macroscopic scale while the outer surface of the projecting tab has surface features causing the outer surface of the projecting tab to have a surface area that significantly exceeds the surface area that the outer surface of the projecting tab would have if smooth on a macroscopic scale.
