Abstract: A wall trimming element for positioning at an angled section of a wall includes a base portion and a bead. The base portion includes a first flange, a second flange, and a mounting portion positioned between and connecting the first flange and the second flange. The mounting portion includes a longitudinally extending first bend forming a first segment at one side of the first bend and a second segment at another side of the first bend. The first segment is angled relative to the second segment. The mounting portion also includes a first ridge and a second ridge, spaced from the first ridge. The bead is positioned on the mounting portion between the first ridge and the second ridge. The bead includes a second bend that is configured to be positioned over the first bend of the mounting portion.

Abstract: A drywall-trimming strip for trimming an archway has a nose with a tabbed edge and a flanged edge. A first series of slits spaced from one another define a series of tabs spaced from one another along the tabbed edge. A flange extends from and along the flanged edge. The tabs are joined to the tabbed edge of the nose by a continuous juncture extending along and defining the tabbed edge of the nose, which has a second series of slits extending to the continuous juncture and spaced from one another, as the slits defining the tabs are spaced from one another. All parts of the drywall-trimming strip are made from a comparatively harder, less flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer Shore 82 D, except for the continuous juncture, which is made from a comparatively softer, more flexible material, such as polyvinyl chloride having a hardness of Durometer Shore 92 A.

Abstract: In a sanding block having two expansive sides and two adjacent sides, each adjacent side adjoins each expansive side at a given one of two opposite edges of that expansive side. The expansive and adjacent sides are abrasive. When viewed macroscopically before the sanding block becomes worn, the expansive sides between their opposite edges are planar and are parallel, a given one of the opposite edges of each expansive side is a curved edge, which defines a radius not less than about ? inch at any location on the curved edge, and the other one of the opposite edges of each expansive side is a sharp edge, which defines an acute angle in a range from about 55° to about 70°. The curved edges are intended to minimize gouging or scuffing due to uneven pressure being applied by a user holding the sanding block in one hand and to minimize damage when gouging or scuffing due thereto occurs.

Abstract: A drywall trimming element for bridging two sections of drywall is an extruded element having first and second opposing flanges each having an interior surface and an exterior surface. The element is secured to the drywall by joint compound. The interior surfaces are adapted to be positioned on or adjacent to a respective one of the drywall surfaces. The interior and exterior surfaces each define respective surface planes. One or both of the interior and exterior surfaces have a plurality of upstanding longitudinally oriented ribs extending outwardly from the surface. The ribs extend away from their respective surfaces and define a void space between the surface adjacent to the ribs and an end of the ribs, such that a line extending outwardly from and normal to the surface of the flange adjacent to the ribs traverses through the void space and then subsequently contacts the ribs. The void space serves to provide a joint compound locking feature for the trimming element.

Abstract: A corner defined where a wall panel and a ceiling panel meet is trimmed by a crown molding assembly comprising a wall platform, a ceiling platform, a crown molding member, a wall edge-trimming bead, and a ceiling edge-trimming bead. The wall platform is affixed to the wall panel, at or near the corner, and has an expansive surface spaced from the wall panel. The ceiling platform is affixed to the ceiling panel, at or near the corner, and has an expansive surface spaced from the ceiling panel. The crown molding member is affixed so as to bridge the expansive surfaces of the wall and ceiling platforms. The wall edge-trimming bead is affixed so as to cover an outer edge of expansive surface of the wall platform. The ceiling edge-trimming bead is affixed so as to cover an outer edge of expansive surface of the ceiling platform. Each platform may comprise a drywall layer or stacked drywall layers.

Abstract: As used to trim a corner where a wall and a ceiling meet, a crown molding member has a planar portion, an intermediate portion, and a mounting flange. The planar portion is attached to the ceiling, in a first mode, or to the wall, in a second mode. The intermediate portion may have a coved, stepped, or curved profile. When applied to the mounting flange, drywall-finishing material, so-called “mud” in trade parlance, is pressed through apertures in the mounting flange, against the wall, in the first mode, or against the ceiling, in the second mode.

Abstract: As extruded from a polymeric material, such as polyvinyl chloride, a drywall-trimming strip has a central portion, which has a bullnose region and two planar regions, one at each side of the bullnose portion. Further, the drywall-trimming strip has two lateral flanges, each of which is joined unitarily to the bullnose portion by a stepped junction. The bullnose region has an exterior radius of 0.350 inch approximately. Each planar region has a width of 0.217 inch approximately, as measured in a plane normal to an axis defined by the bullnose region. Each junction has a measurement of 0.095 approximately, as measured between a plane defined by the exterior surface of the bullnose portion and a plane defined by the interior surface of the flange at such junction. Having a thickness of 0.055 inch approximately, the strip is adapted to fit along an elongate corner defined by two drywall panels, each of which has a thickness not less than 0.

Abstract: In a drywall-trimming accessory molded from a polymeric material, such as polystyrene, and having two flanges, which diverge from each other, each flange is adapted in an intended use to cover an edge portion of a drywall panel and to have a fastener driven through said flange. Each flange has a mosaic of break-away panes. Each pane being adapted to break away from the flange having such pane, along at least one of the grooves defining such pane, if such pane is struck by a fastener being driven through the flange having such pane. Preferably, each pane is defined by two elongate, parallel apertures and by two elongate, parallel grooves, which are formed in an inner surface of the flange having such pane.

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.

Abstract: For trimming an archway, a drywall-trimming has a nose with an outer surface and an inner surface. The outer surface has a curved portion conforming substantially to an arcuate profile with a radius in a range from approximately 1/4 inch to approximately 3/4 inch. The drywall-trimming strip has a series of slits defining a series of tabs spaced from one another along a tabbed edge but not extending into the nose. Near the tabbed edge, the slits have widened, oblong portions. Usually, the drywall-trimming strip has a flange extending from and along an opposite edge, but the flange is omitted for some applications. A comparatively softer portion, which includes the juncture where the tabs are joined to the tabbed edge, is made from a comparatively softer, more flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer 92 Shore A.
