Drywall-trimming accessory and methods for making same and/or preparing same to adhere to drywall-finishing compound
First Claim
1. A method for making a drywall-trimming accessory having a flange, which has two expansive surfaces facing oppositely, and for preparing the drywall-trimming accessory to adhere to a drywall-finishing compound contacting at least part of at least one of the expansive surfaces of the flange, wherein the drywall-trimming accessory is made from a cellular polymer and wherein a superficial layer is removed from the same part of the same one of the expansive surfaces of the flange so as to reveal open cells of the cellular polymer.

Abstract
As made from a cellular polymer, a drywall-trimming accessory has two diverging flanges, each of which has two expansive surfaces facing oppositely. A superficial layer is removed from the same part of each expansive surface of each flange, as by milling, so as to reveal open cells of the cellular polymer. Where the superficial layer has been removed, a drywall-finishing compound contacting the same part of each expansive surface of each flange adheres well. As examples, which are not intended as limiting, the drywall-trimming accessory may be an elongate strip, which may be extruded from polyvinyl chloride, or a two-way or three-way corner, which may be molded, as by injection molding, from polystyrene or acrylonitrile-butadiene-styrene.
