The present disclosure relates to an inside corner drywall finishing, more specifically but not by way of limitation, an inside corner drywall finishing that is effortlessly installed to the common vertex of three adjacent walls for effective joining and sealing of drywall joints, as well as any gaps, cracks or any other openings and deficiencies.
Between applying a semi-liquid sealing substrate, drying times between coats, and smoothing out and sanding imperfections, drywall finishing is an exceedingly lengthy process. Presently, the majority of the skilled work for a drywall finisher is required in finishing inside corners for three-way wall connections. This is partially due to connections are almost never completely orthogonal which requires modification by the drywall finisher to achieve straight lines. Factoring in the number of inside corners that are typically present in residential and commercial construction projects, a great deal of skilled labour, time and money is exhausted. Current methods for finishing inside corners largely include caps or using three rectangular pieces of tape finishing. These methods may require some modifications, which add to lengthy installations, as well as pre-fill and dry times.
U.S. Pat. No. 5,893,246 A (Smythe Jr.) discloses an inside drywall corner finishing. Shortcomings include the requirement to apply drywall mud during assembly, as well as any adjustments required for walls that are not orthogonal are impractical and time consuming to implement.
All documents cited herein are incorporated by reference.
There is a need for inside corner drywall finishing that effectively joins and seals joints, gaps, cracks, holes any other openings and deficiencies, that is durable, is reinforced to prevent crackling, slipping or bubbling, and can be effortlessly employed and adjusted in a timely manner.
It is the object of the present invention to provide an inside corner drywall finishing.
In accordance with an aspect of the invention, there is provided an inside corner drywall finishing comprising a first segment composed of a first side and a second side, a second segment composed of a first side and a second side, a third segment composed of a first side and a second side, a flap composed of a first side and a second side, the first side of the first segment attached to the first side of the flap wherein the first segment is affixed to the flap, the second side of the first segment attached to the first side of the second segment wherein the first segment is affixed to the second segment and the second side of the second segment attached to the first side of the third segment wherein the second segment is affixed to the third segment.
In accordance with another aspect of the invention, there is provided a method of using the inside corner drywall finishing to join and seal a common vertex and joints between three adjacent walls, comprising applying the first segment against a first wall between a first wall and third wall joint and a first wall and second wall joint, applying the second segment against a second wall between the first wall and second wall joint and a second wall and third wall joint, applying the flap against a third wall between the second wall and third wall joint and the first wall and third wall joint and applying the third segment against the flap and the third wall between the second wall and third wall joint and the first wall and third wall joint.

In accordance with an embodiment of the invention, wherein one or more of the first segment, the second segment, the third segment or the flap tapers away from a common vertex of the first segment, the second segment, the third segment and the flap.
In accordance with an embodiment of the invention, wherein the inside corner drywall finishing is composed of one or a combination of paper, metal or plastic.
In accordance with an embodiment of the invention, wherein the second wall is a ceiling.
In accordance with an embodiment of the invention, wherein an adhesive on one or more of the first segment, the second segment or the third segment is activated prior to application.
In accordance with an embodiment of the invention, wherein the adhesive on the flap is activated prior to applying the flap against the third wall.
In accordance with an embodiment of the invention, wherein the adhesive on the flap is activated prior to applying the third segment against the flap.
In accordance with an embodiment of the invention, wherein a semi-liquid sealing substrate is applied to one or more of the first segment, the second segment or the third segment following application.
In accordance with an embodiment of the invention, wherein a semi-liquid sealing substrate is applied to the flap following application of the flap against the third wall.
