FIELD OF THE INVENTION 
       [0001]    This application claims the benefit of U.S. Provisional Application No. 62/069,514, which was filed on Oct. 28, 2014. The present invention relates generally to a system for mixing construction materials, more particularly, the system comprises a nonstick modified elastomer bucket skin liner and an elastomer-coated set of tools. The system enables a user to mix construction materials effectively and efficiently. 
       BACKGROUND OF THE INVENTION 
       [0002]    It is often the case in the construction and remodeling environment that mixtures are ii unevenly mixed or not thoroughly mixed. When mixtures are placed into buckets for mixing, there are often corners of the bottom of the bucket that comprise partial dry unmixed material that is wasted. Further, most bucket systems do not allow for tools to effective access the entire bucket or bucket liner during the mixing process. Often bucket systems are not constructed in a manner to use all of the material because of the curvature of the bucket, bucket liner or tools. Mix material is wasted and not thoroughly mixed. Time, money and material is often wasted. Therefore there is a long-felt need for a more effective bucket skin system that provides for thorough mixing and conservation of mix material. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE INVENTION 
       [0015]    Reference will now he made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference characters refer to the same or similar elements in all figures. 
         [0016]    At the left portion of  FIG. 1 , a commercial or contractor bucket  6  is depicted. For purposes of this invention, the bucket skin mixer system is independent of size and can accommodate 1, 3, 3.5, 5, 8, 10 and 15 gallon buckets or any other size commercial sized bucket. The commercial bucket has in internal surface  7  that contact materials held in the bucket, a bucket bottom  8  and walls  9 . At the left of  FIG. 1 , a bucket skin, liner  1  is depicted. The bucket skin liner  1  comprises a bottom  5 , walls  4  and upper lip  2 . The upper lip  2  further comprises a nipple  3  disposed atop the upper lip of the bucket skin line  1 . 
         [0017]      FIG. 2  depicts a planar cross sectional of the objects depicted in  FIG. 1 . In this cross sectional view, the internal predetermined curvature R of the bucket liner is shown at the intersection of the bottom  5  and wall of the bucket skin liner. The internal predetermined curvature R is constant between the material of the bottom  5  and the wall  4  and around the entire bottom. 
         [0018]      FIG. 3  depicts the bucket skin liner  1  with internal predetermined curvature R between the bottom  5  and wall  4  inside the bucket walls  6 . In this embodiment, the bucket skin liner is disoposed inside the the bucket  6  with the internal bucket bottom surface in contact with tehexternal bucket skin liner. The upper lip of portion fits over the top of the bucket  6 . 
         [0019]      FIG. 4  depicts examples of two bladed tools, a trowel  10  and bladed agitator  20 , and bucket skin liner  1  having internal predetermined curvature R between the bottom  5  and the walls  4 . The trowel  10  has a handle portion and a distal end. In actual use, the distal end makes contact with the construction material mixes in the bucket sin liner and often the bucket skin liner itself. The distal end is has bladed portion having a bottom portion  11  and side portion  12 . The bladed portion has a curvature R′ between the bottom portion  11  and the side portion  12 . The trowel bladed curvature R′ is the same curvature as the internal predetermined curvature of the bucket skin liner R. 
         [0020]      FIG. 4  also depicts a bladed agitator  20  between the bucket skin liner and the trowel. The bladed agitator  20  has a handle portion and a distal end. In actual use, the distal end makes a contact with the construction material mixes in the bucket sin liner and often the bucket skin liner itself. The outer most blades of the bladed agitator  20  have a bottom blade  21  and side blades  22  with a curvature R″ therebetween. The curvature R″ is the same curvature as the internal predetermined curvature of the bucket skin liner R. The matched curvature of R with either R′ or R″ comprises a mix system to thoroughly and effectively mix dry materials. 
         [0021]    By matching the curvature of the blades of the trowel or the bladed agitator with the curvature of the bottom of the bucket skin liner there is efficient effective mixing and less loss of construction material mix. It has been demonstrated that significantly less material remains dry during mixing of construction material mixes, including any mixes selected from the group consisting of cementous materials, adhesives, epoxies, paints, dry wall, thin set, grout, patches, levelers, stucco and other construction materials used during a material mix, application and clean-up. Further, the mixing is more uniform since no material remains between the blade edges of tool and the internal surface of the bucket skin liner, particularly in and around the area of the internal predetermined curvature of the bucket skin liner during the mix action or application action. This contributes to significant cost savings and conservation of material. Additionally, the cleanup is easier with less powder or semi wet material remaining. 
         [0022]    Another important feature of the bucket skin mixer system is that both the bucket skin and the at least one tool is comprised of an elastomeric material. The elastomeric material is selected from any material of the group consisting of urethane, silicone, plastic, rayon synthetic materials, and metamaterials. The elastomeric material must be sufficiently robust and pliable to withstand mechanical mixing and continuous mixer and trowel impact. In many embodiments of the bucket skin liner mixer system, a tool, trowel blade or blade of bladed agitator is comprised of a elastomeric material coating, such that the underlying tool is comprised of metal or similar material and the coating is of elastomeric material. 
         [0023]      FIG. 5  depicts the upper lip portion  2  of the bucket skin liner  1 . A nipple portion  3  is disposed atop the upper lip portion  2 . The nipple portion may be disposed atop the entire perimeter of the top of the upper lip portion, or alternatively, may only partially cover the perimeter portion of the upper lip portion. The nipple portion provides a wiper to aid in the removal of material off the blades and edges of the tools used to mix or apply the material. Also depicted in  FIG. 5  is an extended and downward-curved portion  30  of the upper lip portion  2 , This extended and downward-curved portion  30  allows the bucket skin liner  1  to encapsulate the top of the bucket for more effective gripping of the bucket and remain securely attached during mixing operations and mixing action. 
         [0024]      FIG. 6  shows the nipple portion  3  disposed atop the upper lip portion  2  cleaning and wiping of mix material off a trowel  10 , The nipple portion effectively conserves material thereby reducing costs. 
         [0025]      FIG. 7  shows the trowel being cleaned by the nipple, with the arrow depicting the motion of the tool over the nipple. 
         [0026]    It is believed that the apparatus of the present invention and many of its attendant advantages will be understood from the foregoing, description. It is also believed that it will be apparent that various changes may he made in the form, geometry, construction, and arrangement of the components without departing from the scope and spirit of the invention and without sacrificing its material advantages. The forms described are merely exemplary and explanatory embodiments thereof. It is the intention of the following claims to encompass and include such changes.
