Abstract
The present invention relates to a system for finishing an interior or exterior drywall surface of a building structure. More specifically, a means of applying a predetermined formulation of dispensable compound material in liquefied form at continuous flow with simultaneous finishing characteristics thereby reducing labor intensity and maximizing finish quality to a level 5 standard.

Description
SUMMARY OF THE INVENTION AND ADVANTAGES
[0010] The subject invention comprises a method and apparatus in a complete operation, that streamlines the currently employed and the scope of work of labor allocation and intensiveness, efficiency of liquefied compound application and surface finishing to desired properties and appearance.
[0011] A preferred embodiment of the apparatus is significantly reduced apparatus weight and ergonomics, for expediency in workmanship. In application by operation, the apparatus reduces compound waste as it utilizes consistently direct application at pre-determined distances from the output source to target surface thereby eliminating excess residual compound and waste. The tool is easy to manufacturer thereby reducing expendable tool costs from project to project.
[0012] In combination with the compound delivery to the target surface the apparatus works in combination with a finishing tool simultaneous to the velocity and viscosity of the liquefied compound. There is no flat finishing box or storage cannon as utilized in existing continuous flow drywall tools and no finish squeegee.
[0013] The apparatus has the capability of performing and completing the same project scope of work at a factor of 3.5 (three and a half times) more efficiency than existing methods of construction and implementation.
[0014] Compound is driven from a source hopper tank through a hand held directed applicator consisting of an extension handle and distribution head that outputs formulation suitable for high speed drywall treatment in the form of variable characteristic droplets at predetermined velocity and viscosity in a fan shaped pattern from a spraying distribution head located on the tool handle with the finishing head, allowing one laborer to fulfill an operation normally comprising of a team of at least three laborers in individual steps.
[0015] As an integral object of operation of the application apparatus consists of:
[0016] (a) the distance to the target surface is variable via attachable-detachable pre-sized roller wheels that glide consistently along the target surface and are available in a variety of diameters to adjust to the desired surface quality
[0017] (b) the width and spread of the coverage to target surface, is variable via adjustable arms that predetermine the placement and width of compound material distribution density and coverage
[0018] (c) interchangeable smoothing blade widths from 6″ to 36″ integrate to the adjustable arms in correlation with the desired surface quality and target coverage in (b). Prior to this tool one had to manually apply the joint compound from a bucket to the wallboard, then go back with a separate tool and wipe the joint compound excess down to achieve a rough finish and then go through a further process of sanding and further smoothing. This resulted in a lot of wasted material as well as many wasted man hours.
[0019] This tool, by attaching it to an airless pumping system applies the joint compound to the wallboard by spraying and smoothing the joint compound in one step. This will require only one man to perform what used to take at least 3 men to do. The tool allows you to control the fan of the joint compound with a conventional spray gun. The tool keeps the spray fan of the joint compound the exact distance from the wallboard surface that is needed in order to achieve a perfect finish. With the attached squeegee the tool will perfectly smooth the joint compound onto the wallboard joints, which will in turn achieve a perfect finish in one step with less material waste and less man hours.
[0020] There will be 3 different size tools to apply the 1.sup.st, 2.sup.nd and 3.sup.rd coats of joint compound that is required to finish wallboard. This tool will allow work to be performed from the floor on 10′-12′ walls and ceilings without the need for scaffolding, stilts or ladders. One man can perform the work on both tops and bottoms of the wallboard.
[0021] With a 50 foot hose attached to the airless pumping system it will minimize the trips needed going back and forth to the bucket that holds the joint compound in order to fill up your handheld tools. The tool also applies compound (“mud”) directly to the wallboard surface thereby not dropping joint compound on the floor and wasting it. You and your work area will remain much cleaner than it would have using the conventional methods.
[0022] You will be able to put a larger surface area of joint compound on the wallboard joint that will be flatter and smoother than conventional methods. The typical 12″ joint will become a 22″ joint using less material resulting in a smoother finish.
[0023] Once mastered, the tool will make applying joint compound much faster than it has ever been applied using conventional methods. The tool will make applying the sought after, flawless Level 5 finish much more achievable. It provides for consolidating a multiple of steps into one operation, making Level 5 applications of drywall material more efficient and utilizing less man power and materials. Overall you can achieve a smoother more perfect finish that will require much less sanding, waste and man hours than conventional application methods.
[0024] While the present invention has been described in terms of particular embodiments and applications, in both summarized and detailed forms, it is not intended that these descriptions in any way limit its scope to any such embodiments and applications, and it will be understood that many substitutions, changes and variations in the described embodiments, applications and details of the method and system illustrated herein and of their operation can be made by those skilled in the art without departing from the spirit of this invention.
