ABSTRACT:
A drywall-trimming assembly comprises a drywall edge-trimming strip extruded from polyvinyl chloride and a drywall corner-trimming device molded from acrylonitrile-butadiene-styrene. The drywall corner-trimming device has a projecting tab, which fits 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. The projecting tab has a pattern of alternating ridges and grooves, which extend between the lateral edges of the projecting tab. An adhesive of a type that adheres comparatively less strongly to a unit of surface area of the outer surface of the projecting tab and that adheres comparatively more strongly to a unit of surface area of the inner surface of the end portion of the drywall edge-trimming strip is used for adhering the outer surface of the projecting tab to the inner surface of the end portion of the drywall edge-trimming strip. 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 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.
