For trimming a drywall corner, a drywall-trimming article has an elongate portion and two flange portions, which are extruded unitarily with the elongate portion from polyvinyl chloride. The elongate portion has an arcuate profile. Each flange portion has an array of apertures. One of the convex and concave surfaces defined by the central portion is covered substantially with discrete fibers, which adhere to the substantially covered surface but which do not cover the remaining surfaces of the central portion and of the flange portions. Such adhering fibers facilitate application of a coat of paint and texturization of the coat of paint over the substantially covered surface without separating the inner surfaces of the flange portions from the underlying drywall by any appreciable thicknesses due to such adhering fibers. The apertures are substantially free of such adhering fibers so that drywall-finishing material, when pressed onto the outer surfaces of the flange portions, can be thus pressed through the apertures, into intimate contact with the underlying drywall, without intrusion of said adhering fibers that could interfere with bonding between such material pressed therethrough and the underlying drywall. |
