     The present application is a continuation patent application of the U.S. patent application Ser. No. 12/357,274, filed on Jan. 21, 2009 now abandoned, the entire contents of which are incorporated herein by reference. 
    
    
     STATEMENT RE: FEDERALLY SPONSORED RESEARCH/DEVELOPMENT 
     Not Applicable 
     BACKGROUND 
     The present invention relates generally to concrete products, and more particularly, to a method of imprinting a visual and textural decorative pattern upon a concrete surface. 
     As is well known in the building and construction trade, concrete is extensively utilized as a building material for industrial, commercial and residential applications. Due to its durability, water resistance, and cost economy, concrete has gained wide spread use in flooring applications. As a result of wide spread use and popularity, the market is currently demanding concrete surfaces that have an improved aesthetic appeal with limited imperfections and irregularities. Common imperfections include blowholes, or minor lines and cracks that may form while the concrete is cured. 
     In order to meet this demand, the concrete trade has developed various coloring and surface finishing techniques designed to enhance the aesthetic appeal of concrete surfaces while masking imperfections and irregularities that may exist in the exposed surface areas. An example of such a finishing technique includes push broom finishes. Familiar push brooms such as are commonly used in sweeping floors are pulled across the drying concrete surface, leaving a pattern formed by the bristles as they pass across. Such brooms will ordinarily be found to possess threaded apertures into which a handle with perhaps one or more extensions may be fitted. The resultant bristled appearance provides a generic broom pattern across the concrete surface and serves to hide irregularities and imperfections that may exist thereupon. However, the bristled appearance left by the push brooms is often undesirable as it is not aesthetically pleasing and fails to provide any variations in depth, size, or diameter within the contours of the texture. Additionally, a push broom is increasingly unwieldly and it being the general experience that a push broom is unable to provide a consistent uniform finish across the surface. 
     Another known method of providing visual and textural effects to a concrete surface is the exposed aggregate method. The exposed aggregate method may be used to diminish the appearance of imperfections within a concrete surface while creating an aesthetically appealing application of concrete. Applicant has conducted extensive research and has developed a variety of methods improving upon the exposed aggregate method, including a variety of surface seeded exposed aggregate products and methods. In particular, several of these methods and products are described in Applicant's U.S. Pat. Nos. 4,748,788, 6,016,635, 6,033,146, and U.S. Patent Publication No. US 2007/02346, the contents of which are incorporated herein by reference. 
     In a particular surface seeded exposed method, subsequent to pouring the concrete, rock or gravel aggregate is scattered (i.e. broadcasted or seeded) over the top surface of the concrete and subsequently troweled into the same. As the concrete cures, the aggregate becomes adhered to the top surface of the concrete and is thus exposed. Although various sizes of aggregate can be broadcast over the top surface of the concrete in this method, such aggregate is normally of about three-eighths inch diameter or greater in size, and has sheared or jagged edges. The size and shape of the aggregate allows it to be worked into the top surface of the concrete and adequately adhered thereto. Applicant's techniques as described in the above-mentioned patents overcame many of the deficiencies of the prior art and produced improved surface finishes on surface seeded exposed aggregate concrete. In particular, the concrete resultant from practice of the above-mentioned patents exhibits an extremely flat exposed aggregate surface suitable for extremely high traffic flooring applications. 
     A requisite feature of surface seeded exposed aggregate is the addition of aggregates to the concrete surface. Therefore, there is a need in the art for applying a visual and textural decorative pattern upon a concrete surface capable of concealing imperfections or irregularities thereupon. 
     BRIEF SUMMARY 
     According to a preferred embodiment of the present invention, a method of imprinting a visual and textural decorative pattern to an uncured concrete surface is provided. Implementations of the present invention include a concrete product having a surface that models the fine, medium, and/or coarse grain textures of wood, lightly finished cut or honed stone, and the like. Further implementations of the present invention include a concrete product having a surface that incorporates a design pattern featuring any visual or textural pattern in accordance with a pattern imprinted upon a decorative finishing tool. Thus, implementations of the present invention may provide a concrete surface that precisely assimilates the characteristics and colors of wood or stone, including graining, fractures, and/or rock texture properties common in cut or honed stone implemented by utilizing a single finishing tool. Additionally, the unique design pattern serves to shield imperfections and irregularities existing on the concrete surface. 
     The method generally commences by preparing the concrete surface so that the decorative pattern may be implemented. In this regard, the initial step requires pouring a concrete mixture over the subgrade, with the concrete mixture defining an upper exposed surface when poured. Prior to the concrete mixture being poured thereover, the subgrade is preferably prepared to a desired grade. Such preparation preferably comprises compacting the subgrade to approximately 90% compaction. The compaction of the subgrade may be followed by the placement of a layer of sand thereupon, and the subsequent placement of reinforcement members (e.g., rebar) upon the layer of sand. When the layer of sand and reinforcement members are provided with the prepared subgrade, the concrete mixture is poured over the layer of sand and the reinforcement members such that the reinforcement members are encapsulated therewithin. 
     After the concrete mixture has been poured, the same is preferably screeded to a desired grade, which is followed by the step of finishing the exposed surface of the concrete mixture with a finishing tool, such as a vibrating metal bull float, to dispose a quantity of cement/fines paste derived from the concrete mixture at the exposed surface thereof. The finishing of the exposed surface via the vibrating metal bull float in this particular step also seals the exposed surface. It is contemplated that this initial finishing step may be completed through the use of either a vibrating magnesium bull float or a vibrating aluminum bull float. The Lievers Holland Company sells a preferred metal bull float under the trademark HAL 200. 
     It is contemplated that the decorative pattern may be implemented upon all types of concrete surfaces including surface seeded exposed aggregate. If the concrete surface is a surface seeded exposed aggregate then subsequent to the completion of the initial finishing step, a quantity of aggregate is broadcast upon the exposed surface of the concrete mixture. The aggregate may comprise silica sand, glass bead, coarse sand (e.g., Monterey Aquarium coarse sand), organic materials (e.g., sea shells), metals, or composite materials. The aggregate may comprise of particular materials specifically needed to create the sought after pattern. The quantity of aggregate is preferably broadcast over the exposed surface of the concrete mixture at an approximate rate of one pound per square foot of the concrete mixture. It is contemplated that the aggregate selected should carry certain requisite design features sought in the decorative patterns, such as size, color, or reflective qualities. 
     After being broadcast about the exposed surface of the concrete mixture, the quantity of aggregate is then preferably mixed into the quantity of cement/fines paste through the use of the vibrating metal bull float. As indicated above, the vibrating metal bull float used in the mixing step may comprise either a vibrating magnesium bull float or a vibrating aluminum bull float. Importantly, this mixing step is used to fully embed the quantity of aggregate into the quantity of cement/fines paste. 
     Subsequent to the initial preparation of the concrete surface, the exposed surface of the concrete mixture is finished with a decorative finishing tool thereby imprinting a decorative pattern on the exposed surface. In this regard, the predetermined pattern may be any visual or textural pattern such as wood grain, or light ground finishes found in cut or honed stone. A decorative finishing tool includes a blade having an impression of the decorative pattern formed thereupon. The blade is then troweled over the exposed surface of the concrete mixture to imprint the decorative pattern upon the exposed surface. The blade may have a custom designed template having protrusions such as rods, or indentations to uniquely form the decorative pattern. It is contemplated that protrusions, such as rods, may be rigidly attached to the blade through conventional means known in the art such as adhesives, welding, or fitting into grooves. It will be appreciated that the decorative pattern may have variations in depth, length, or size while still being formed by a single decorative finishing tool. Thereby, permitting a user to create such an aesthetically pleasing surface without the need for additional manpower. 
     Upon the implementation of the decorative pattern, the concrete surface is cured. In this regard, it is contemplated that a variety of finishing techniques may be employed specific to the type of concrete being utilized. Resultantly, a concrete surface having an aesthetically appealing visual and textural decorative pattern formed thereupon is provided. It will be appreciated that such a surface may be utilized in high traffic applications and retains the stability and durability features of concrete.

     DETAILED DESCRIPTION 
     Referring now to  FIGS. 1-5 , pictorially and schematically illustrating the method transferring a visual and textural design to an uncured concrete surface of a concrete mixture utilizing a decorative finishing tool. The preferred method utilizes a decorative finishing tool to implement a pattern on the exposed surface of the concrete. As a result, the concrete is given an aesthetically pleasing appearance having various depths, sizes, diameters, and length within the contours of the texture thereby resembling natural patterns such as wood grain, or lightly finished cut or honed stone. Additionally, such contours and designs conceal imperfections and irregularities from the concrete surface. 
     The preferred method commences by preparing the concrete surface. In this regard, the initial step comprises preparing the subgrade  10  to a desired elevation and grade. The subgrade  10  layer of a pavement is, essentially, the native material underneath the pavement. It is also known as the “formation level”, which can be defined as the level at which excavation ceases and construction starts, therefore it is the lowest point of the pavement structure. Generally, a subgrade  10  requires some basic preparation for adaptation for construction purposes, this process is known as ‘subgrade formation’ or ‘reducing to level’. Such preparation preferably comprises compacting the subgrade  10  to approximately 90% compaction. Subsequent to being compacted, the subgrade  10  is preferably covered with a layer of clean, moist fill sand  12  which is preferably maintained at a minimum four inch thickness. Although the fill sand  12  is not absolutely necessary for the method of producing the decorative concrete surface of the present invention, it is highly desirable to control the hydration process of the concrete. In order to increase the resultant strength of the concrete and reduce subsequent cracking of the same, reinforcement members  14  such as wire mesh or rebar is/are positioned upon the layer of fill sand  12 . 
     With the reinforcement members  14  in place, a concrete mix or mixture  16  is poured over the layer of fill sand  12  and the reinforcement members  14  such that the reinforcement members  14  are encapsulated therewithin. The concrete mixture  16  is poured to approximately a three and one-half to four inch thickness. Although variations in the concrete mixture  16  are clearly contemplated, a preferred concrete mixture  16  comprises 70% sand and 30% three-eighth inch mean diameter aggregate combined with six sack cement (two thousand pounds per square inch) or seven sack cement (three thousand pounds per square inch). Dependent upon individual desires, various color mixtures can be added to the concrete mixture  16 . The color of the concrete mixture  16  may be specifically selected to complement the overall design being implemented in the decorative pattern. It is contemplated that a variety of colors to enhance the effects of the decorative pattern  24  may be employed by the present invention. In the present embodiment of the invention, the decorative pattern  24  implemented on the concrete structure is similar to wood grain. Therefore, the color of the cement mixture  16  may be reflective of wood, taking the color of brown or dark brown or a mixture of colors complementing the desired aesthetic appeal of the decorative pattern  24 . It is further contemplated that numerous colors may be employed at various stages of concrete preparation process to obtain varying shades of color if so desired. 
     After the concrete mixture  16  has been poured, the same is preferably screeded to a desired level plane or grade. Screeding is leveling and smoothing the top layer of the concrete mixture  16 , so the mixture  16  is the same height as the forms, or guides, that surround it. The screeding of the concrete mixture  16  results in the same defining a generally level or planar upper exposed surface  18 . Therefore in order to facilitate the implementation of the decorative pattern, subsequent to screeding, the exposed surface  18  of the concrete mixture  16  is surfaced or finished with a conventional finishing tool to dispose a quantity of cement/fines paste derived from the concrete mixture  16  at the exposed surface  18  thereof. 
     In the preferred embodiment, a vibrating metal bull float is utilized as the finishing tool. Such vibrating metal bull floats are known in the art and are characterized by possessing an extremely smooth or polished surface which, in addition to bringing up the appropriate amount of cement/fines paste for the subsequent manipulative steps of the present invention, also tends to seal the exposed surface  18  of the concrete mixture  16 . It is contemplated that this initial finishing step may be completed through the use of a conventional bull float. A bull float consists of a trowel blade produced from a specially designed hollow section alloy extrusion with a convex profiled sole. Typically, the blade angle is easily controlled to facilitate forward and backward movement by a blade pitch control. A bull float generally provides very accurate levels without the need for guiding rails. In the present embodiment, it is preferred that either a vibrating magnesium bull float or a vibrating aluminum bull float is utilized. A preferred metal bull float is sold under the trademark HAL 200 by the Lievers Holland company. 
     According to one aspect of the present invention, when the exposed surface is in the plastic state, fine sand  20  may be broadcast over the exposed surface  18 . The fine sand  20  may be of any given color or texture, as required by the decorative pattern  24 . Further, it is contemplated that various combinations of color, texture, or other characteristics of the fine sand  20  may be selected in order to complement the decorative pattern  24 . 
     It is contemplated that the present invention may be implemented upon a variety of concrete surfaces, including surface seeded exposed aggregate. Therefore, in an exemplary embodiment of the present invention, a quantity of aggregate  22  may also be broadcast upon the exposed surface  18  of the concrete mixture  16 . When the exposed surface  18  of the concrete mixture  16  is still plastic, small size exposed aggregate  22  is broadcast over the exposed surface  18 . It is preferred that aggregates  22  be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. The selection of aggregates  22  may impact the aesthetic appearance of the decorative pattern. In this regard, the aggregates  22  are selected to complement the overall visual and textural characteristics of the design pattern. 
     As a result, a variety of techniques may be employed such that the aggregates  22  carry the desired visual and textural characteristics as required by the decorative pattern  24 . In an exemplary embodiment of the present invention, a benefaction process such as jigging or heavy media separation can be used to upgrade the quality of the aggregates  22 . In this regard, once processed, the aggregates  22  are handled and stored in a way that minimizes segregation and degradation and prevents contamination. Aggregates  22  not only impact the aesthetic characteristics of concrete but also influence freshly mixed and hardened properties, mixture proportions, and economy of the concrete. 
     It is preferred that the aggregate  22  comprise silica sand, glass bead, coarse sand (e.g., Monterey Aquarium coarse sand), organic materials (e.g., sea shells), metals, or composite materials. Additionally, it is preferred that any aggregate  22  employed in the present invention be characterized by having a mean average diameter size of approximately one-eighth inch diameter, and further be characterized by possessing a generally rounded external surface configuration. Such small size aggregate  22  is a substantial departure over prior art surface seeded exposed aggregates which typically comprise rock or gravel aggregate having average mean diameters of three-eighths of an inch or greater and are characterized by rough, jagged exterior surfaces. Typically, the aggregate  22  is broadcast over the exposed surface  18  of the concrete mixture  16  by use of square point shovels and is applied at a preferred rate of approximately one pound per square foot of the exposed surface  18  of the concrete mixture  16 . It is preferred that the aggregate  22  should not initially depress below the exposed surface  18  of the concrete mixture  16 , but rather should be broadcast solely to cover the same. 
     After being broadcast upon the exposed surface  18  of the concrete mixture  16 , the aggregate  22  is mixed or worked into the exposed surface  18  of the concrete mixture  16 , and more particularly is mixed into the quantity of cement/fines paste at the exposed surface  18  through the use of the above-described vibrating metal bull float. As indicated above, this vibrating metal bull float may comprise either a vibrating magnesium bull float or a vibrating aluminum bull float. This mixing of the aggregate  22  with the cement/fines paste at the exposed surface  18  derived during the previous vibrating metal bull float step is critical to the process of the present invention and insures that the aggregate  22  is fully embedded into the cement/fines paste, and thus thoroughly adhered or bonded to the exposed surface  18  of the concrete mixture  16  upon resultant curing. In order to maintain the design pattern, it is critical that the aggregate  22  is thoroughly bonded to the exposed surface  18  so that individual pieces of aggregate  22  are not dislodged and impacting the visual and textural effect of the decorative pattern. 
     Subsequent to the mixing of the aggregate  22  into the cement/fines paste at the exposed surface  18  of the concrete mixture  16 , the exposed surface  18  is finished with a decorative finishing tool  26  to implement the decorative pattern  24  upon the exposed surface  18 . A decorative finishing tool  26  is a concrete finishing tool that imprints a visual and textural decorative pattern  24  upon the exposed surface  18  of the concrete mixture  16 . It is contemplated that the decorative finishing tool  26  may be utilized upon any concrete surface. The decorative finishing tool  26  includes a blade  28  having first and second opposing sides  28   a ,  28   b . The first opposing side  28   a  is adapted to have a handle  30  or the like so that a user may easily navigate the decorative finishing tool  26  about the exposed surface  18 . It is contemplated that the first opposing side  28   a  may carry an insert for employing conventional attachments known in the art such as broom handles and the like. It is further contemplated that the decorative finishing tool  26  may be adapted to work with existing trowels, floats, vibrating floats, and the like. 
     The second opposing side  28   b  is smoothed or troweled over the exposed surface  18  and imprints the design pattern  24  thereupon. The second opposing side  28   b  is adapted in accordance with the parameters of the design pattern  24  so that the when the decorative finishing tool  26  is troweled over the exposed surface  18 , the blade  28  creates the visual and textural design impressions upon the exposed surface  18 . It is contemplated that a predetermined template of the design pattern  24  may be formed upon the second opposing side  28   b . In a preferred embodiment, the second opposing side  28   b  includes a plurality of rods  32  disposed about the second opposing side. The rods  32  are positioned in accordance to the decorative pattern  24  and configured to create the pattern  24  in the exposed surface  18 . 
     In the present embodiment, the decorative pattern  24  is that of wood grain. Generally, natural wood grain finishes include the alignment, texture and appearance of wood fibers. The appearance of natural wood grain varies depending on the sought after look. For example, one wood finish may include grains which runs in a single direction along the cut wood, a product of a straight growing tree. In a second example, a spiral wood grain where grain which develops as the trunk of the tree twists in development may be the sought after look. In order to capture these varying looks, the rods  32  may be constructed so that each rod  32  is varying in linearity, depth, length, and diameter to provide a naturally looking finish. As further illustrated by  FIGS. 3 and 4 , the rods  32  may be positioned so that there are varying spaces  32  between them which further creates natural finishes found in wood grains. 
     It is contemplated that the rods  32  are rigidly affixed to the second opposing side  28   b  so that the construction of the decorative finishing tool  26  can withstand the rigor of imprinting the decorative pattern  24  upon the exposed surface  18 . In this regard, the rods  32  may be affixed to the second opposing side  32  through conventional welding techniques or through the use of adhesives such as epoxy or the like. It is preferred that the second side  28   b  is configured with grooves  34  that are adapted to rigidly clasp the rods  32 , as illustrated in  FIGS. 2 ,  2   a , and  4 . Therefore, as with the rods  32 , each groove  34  may be configured to have a varying length, size, depth, or width to capture the intended design. It is contemplated that conventional concrete-finishing tools such as floats or trowels may be adapted so that a decorative pattern  24  is formed upon conventional blades and configured to implement the decorative pattern  24  upon the exposed surface  18 . Prior art finishing tools do not provide such a capability and such a pattern would require utilizing numerous tools to create variations in depth, diameter, size and texture within the concrete. As such, the decorative finishing tool  26  provides the appearance of a multi troweled finish. Additionally, the decorative finishing tool  24  advantageously provides a consistent pattern  24  throughout its application over the entire exposed surface  18 . 
     Once the decorative pattern  24  has been troweled on the exposed surface  18  the concrete may be cured or finished. In certain concrete surfaces a variety of finishing techniques are employed to enhance the stability and durability of the surface. It is contemplated, that the implemented design retains its appearance during the employment of a finishing technique. A common finishing technique utilized with exposed aggregate concrete is the application of a chemical surface retarder. A chemical surface retarder is sprayed upon the exposed surface  18  to uniformly cover the same. The chemical retarder slows down the hydration process of the concrete mixture  16 . The chemical retarder does not affect the visual or textural appeal of the decorative pattern  24 . The application of the surface retarder to the exposed surface  18  is followed by the step of finishing the exposed surface  18  of the concrete mixture  16  with a conventional finishing tool or a spray to massage the surface retarder into the cement/fines paste having the aggregate  22  mixed therein. This finishing step preferably results in the penetration of the surface retarder into the cement/fines paste a distance of at least approximately three-eighths of an inch which, due to the relatively small size the aggregate  22  therein, is below the maximum depth of the aggregate  22 . The chemical retarder slows down the hydration process of the concrete mixture  16 . Advantageously, this particular finishing step conducted subsequent to the application of the surface retarder to the exposed surface  18  of the concrete mixture  16  eliminates hard spots in the resultant concrete by facilitating a full mix of the retarder and cement/fines paste. 
     Subsequent to the surface retarder being massaged into the cement/fines paste, a vapor barrier is preferably formed on the exposed surface  18  of the concrete mixture  16 . In the preferred embodiment, the formation of the vapor barrier is facilitated by the application of a liquid chemical evaporation reducer to the exposed surface  18  of the concrete mixture  16 . A preferred evaporation reducer is sold under the trademark CONFILM by the Concrete Tie company of Compton, Calif. An alternative vapor barrier may be formed by covering the exposed surface  18  with four or six mill visqueen. The vapor barrier is maintained upon the exposed surface  18  of the concrete mixture  16  for a prescribed period of time, which may range from approximately two to twenty-four hours. The vapor barrier does not affect the visual or textural characteristics of the decorative pattern  24  upon the exposed surface  18 . 
     After the vapor barrier has remained upon the exposed surface  18  for a prescribed period of time, the exposed surface  18  of the concrete mixture  16  is washed with water to remove any surface films therefrom. In this washing procedure, it is additionally preferable to lightly bristle brush the exposed surface  18  wherein preferably no more than about 5% of the aggregate  22  is dislodged and removed therefrom. The extremely low percentage (i.e., less than 5%) removal of the aggregate  22  from the exposed surface  18  evidences the extremely strong adherence of the aggregate  22  to the exposed surface  18  of the concrete mixture  16 . It is preferred that brushing the exposed surface  18  is done in a manner to minimize any deviation from the intended visual appeal of the decorative pattern  24 . 
     As a result of the washing step, the full mixture of the retarder and cement/fines paste accomplished through the use of a conventional finishing tool known in the art, such as a trowel or float, subsequent to the application of the surface retarder to the exposed surface  18  of the concrete mixture  16  significantly aides in the elimination of perimeter wear-down and excessive dislodgement and loss of the aggregate  22  during this initial washing step. Which resultantly facilitates the preservation of the decorative pattern  24  upon the exposed surface  18 . Additionally, the application of the liquid evaporation reducer to the exposed surface  18  which prevents hydration of the concrete mixture  16  and reduces the rate of evaporation of moisture therefrom increases the ease at which excess cement/fines paste and residual surface retarder are washed from the exposed surface  18  during this initial washing step. In this regard, the aggregate  22  embedded within the decorative pattern  24  is minimally affected. 
     Subsequent to washing, the concrete mixture  16  is cured with water only as opposed to chemical curing agents to avoid any staining of the same or interference with the visual or textural aesthetics of the design pattern, with such water curing typically being facilitated through the use of a conventional fogger or soaker hose. After a prescribed period of time (e.g., 30 days after initiating the curing process) any surface residue present on the exposed surface  18  is removed by conventional power washing with a 90% steam and 10% muriatic acid mixture which is applied by a power washer via a high pressure nozzle. It is contemplated that conventional power washing of the concrete does not detract from the decorative pattern  24  formed upon the exposed surface  18 . 
     The resultant concrete exhibits an aesthetically appealing surface that conceals imperfections upon the surface and is advantageously suitable for high pedestrian traffic flooring applications. Additionally, the surface color and texture may be such that it approximates conventional flooring surfaces such as stone or wood. This resemblance can further be accentuated by saw cutting the concrete surface into rectangular grids to give the appearance that the individual rectangular squares of the grid were laid in a manner analogous to stone or wood flooring. Thus, the present invention comprises a significant improvement in the art by providing a surface seeded exposed aggregate concrete having a decorative pattern formed thereupon and possesses a surface texture and color having improved aesthetics over the prior art. 
     Additional modifications and improvements of the present invention may also be apparent to those of ordinary skill in the art. Thus, the particular combination of parts and steps described and illustrated herein is intended to represent only one embodiment of the present invention, and is not intended to serve as limitations of alternative devices and methods within the spirit and scope of the invention.
