The contents of the three previously mentioned applications are incorporated by reference herein. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to wall and surface veneering products and systems that provide a replica image of a natural surface, such as stone, brick or wood, and is easily installable due to its lightweight characteristics and securement design. The present invention further includes systems for attachment of the veneering product to walls or other surfaces and also includes systems for assembling such products to provide pleasing arrangements and complete wall coverage. The present invention also includes methods of manufacture, which ensures the natural appearance of stone or wood by imaging a natural surface, such as stone or wood, and preparing a mold from that image to mass produce a replica of that particular surface. 
       BACKGROUND OF THE INVENTION 
       [0003]    Even though the use of the actual natural materials (e.g. cut stone, brick or wood) is common in the construction industry, such products have produced challenges that have caused problems related to transportation and installation. For example, the utilization of natural stone, concrete, brick or wood can be cumbersome during transportation and installation of such products due to their heavy weight and the difficulties in easily attaching such products to each other or to the surface of a substrate such as a wall or panel. Furthermore, stone (natural or cultured), concrete and wood products often discolor, stain or degrade over time, thereby damaging their aesthetic appearance and ultimately requiring their replacement. 
         [0004]    The construction industry and home improvement product manufacturers have found difficulties in manufacturing products utilizing materials such as plastic, fiberglass, ceramics and the like that simulate cut stone, brick or wood. Such products have not been able to adequately capture the desired look found in their natural counterparts and in many of these products, have been less that durable. For example, such products often do not have the proper combination of texture, relief and color that would lead an observer to believe it was the natural product rather than a poor simulation. The industry still searches for a construction or resurfacing product that is lightweight, easily installable, consistently durable, provides stunning natural aesthetics and maintains its natural appearance for long periods of time. 
       SUMMARY OF THE INVENTION 
       [0005]    Embodiments of the present invention relate to polymeric or composite wall and surface veneering products and the methods of use and manufacture for such products. The veneering products of the present invention also are produced with one or more materials (e.g. thermoplastics, thermosets, fiberglass, ceramics . . . ) that are resistant to damage and wear caused by the environment, such as sunlight, water, pest infestation and staining from dirt or other organic materials. In various embodiments of the present invention, the utilization of polymers (e.g. high density polyethylene, polypropylene and the like), that are processed using structural foam and other foamed polymer techniques produce wall veneering products that have desirable textures and relief, but still provide incredibly robust and sturdy structural characteristics. Moreover, such structural foam and/or foamed polymer products also accommodate further fabrication of their exposed surfaces, thereby providing the desired texture and color of the natural product, such as stone or wood. The veneering products of the present invention are generally light weight and provide a beneficial alternative to other wall coverings, such as natural or cultured stone, brick, wood and the like.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0069]    The embodiments of the present invention described below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art can appreciate and understand the principles and practices of the present invention. 
         [0070]      FIGS. 1 and 2  depict one embodiment of the polymeric or composite veneering product of the present invention comprising a veneering panel  10  including a front surface  12  having relief and/or texture and a back surface  14  having one or more attachment platforms  16  for securing the veneering panel  10  to a surface. It is noted that the attachment platforms  16  may be alternatively adjoined to the sides of the panel  10  rather than positioned on the back surface  14  depending on the type of attachment means or panel designs. The front surface  12  of the veneering product may comprise one or more colors, textures, degrees of relief and/or designs. For example, as depicted in  FIG. 1 , one embodiment of the veneering panel  10  may appear as a single cut stone. In many embodiments of the present invention, the front surface design is obtained by imaging a natural surface, such as stone, rock, wood or brick. Imaging a natural surface provides a panel that simulates the natural surface and give the most aesthetic appearance. An explanation of imaging is provides below. 
         [0071]      FIGS. 2 ,  3  and  4  depict three embodiments of a back surface  14  of the veneering panels  10  of the present invention. In various embodiments of the present invention, the back surface  14  may be cored or hollowed, thereby reducing the amount of raw material, such as plastic resin, bulk molding compound and/or fiberglass utilized in the panel  10 . The coring of the back surface  14  further provides channels  18  and reservoirs  20  for the free movement of air behind each panel. Such channels  18  and reservoirs  20  assist in preventing the presence and buildup of moisture behind the veneering product, which may deteriorate the building materials positioned behind each panel  10 . 
         [0072]    In some embodiments of the present invention the hollowed back surface may be filled with a sound deadening and/or insulating material. For example, an insulating foam (e.g. a polyurethane foam) may be sprayed or applied to the back surface of each panel to provide additional sound and/or thermal insulation. 
         [0073]    In various embodiments of the present invention, the back surface  14  may be cored or hollowed in a similar replica image of the front surface  12  by including a back surface plate in the mold that has at least a partial replica image of the front surface  12  of the panel  10 . In production, the melted resin would be injected between the front and back surface plates to form each panel  10 . As previously mentioned, the hollowing of the back surface  14  reduces raw materials and in some embodiments provides a substantial uniform thickness for the panel, thereby maintaining the strength and durability of the panel  10 . The uniform thickness also provides benefits in molding the panels  10  by evening the cooling of all portions of the panel  10  during molding. In other embodiments of the present invention the cored back surface  14  may further include one or more ribs  22 , as depicted in  FIG. 5 , that extend from the top of the panel  10  to the bottom of the panel and/or from one side to the other side. Such ribs  22  allow for additional stability and structure to the panel and provides additional durability to address unwanted impacts with the panel  10 . 
         [0074]    The general plastic thickness of the panels of the present invention may vary depending upon the desired rigidity and also the manufacturing process (e.g. panels of structural foam will generally be thicker than panels that are high pressure injection molded). However, various embodiments of the panels of the present invention will have an average thickness of approximately 50 mils to 500 mils. In various embodiments the average thickness will be approximately 80 mils to 300 mils. In additional embodiments the average thickness of the panels will be approximately 120 mils to 250 mils. It is noted that portions of the panel, such as the attachment platforms or ribs, may be of a greater thickness, but a majority of the panel  10  will generally include the thinner wall thickness. 
         [0075]    Furthermore, the front surface of each panel  10  may include various degrees of relief, thereby in some embodiments, providing the appearance of natural cut stone, rock or wood. The degrees of relief generally highlight the texture of the surface and are exhibited by the peaks and valleys present. The degrees of relief may vary depending upon the desired appearance. For example, various embodiments of the present invention may include large amounts of relief (e.g. up to 10 cm from high point to low point) providing a very rough texture. In other embodiments, the relief may be of average degree (e.g. up to 5 cm). And in yet other embodiments, the relief may be somewhat mild (e.g. up to 1.5 cm). 
         [0076]    In various embodiment of the present invention, the front surface  12  of the panel  10  may be flat, rounded or beveled. The front surface  12  of this embodiment may include a beveled front having one or more bends, slants or creases in the front surface  12 . In some embodiments the beveled front surface  12  takes on a tri-panel appearance, such as a beveling or slanting down at the edges. It is noted that the front surface  12  may also be rounded, substantially flat and/or include positions of relief to provide a more natural appearance. 
         [0077]    As previously mentioned, embodiments of the front surface may be flat, rounded, include texture and relief and/or beveled to accommodate molding or fabrication (e.g. lamination, painting, photo or thermal activated coating) to provide the desired appearance. In various embodiments of the present invention the front surface is produced by imaging an actual natural surface, such as natural stone, rock, brick or wood. The imaging of the natural surface can be performed by processes such as cast imaging of the natural surface or by digital scanning the natural surface. When cast imaging the natural surface a mirror image of the surface can be produced by providing a casting material, such as silicone, ceramics or fine sand, and casting it over and/or around the natural surface. Once the casting material sets or has formed a mirror image of the natural surface the object casted is removed from the newly formed mold of the natural surface and an opposite image or negative of the natural surface has been produced. Next the negative image can be cast again with a solidifying material to produce the positive image of the natural surface. Such a process produces a casting that captures the texture and relief of the natural surface. Once the casted mirror images (i.e. positive and negative) are produced, a mold and/or a mold insert manufactured from a suitable mold material, such as aluminum, steel or a ceramic, can be produced for mass manufacture by administering the mold material to the positive and/or negative casting to form the production mold. In various embodiments of the present invention sand or ceramic is used to provide a detailed negative and/or positive image thereby providing the desired detail found in the natural surface which then can be transferred to a more durable steel or aluminum production mold for mass manufacture of panels having one or more natural surface images. Cast imaging of the natural surface may be performed by a cast foundry. Foundries that may be used to prepare such castings include but are not limited to Arrow Pattern and Foundry Company, 9725 South Industrial Drive, Bridgeview Ill. and WK Industries, 6120 Millett Ave., Sterling Heights, Mich. 
         [0078]    Alternatively, a mold may be prepared by digitally scanning the natural surface, such that the surface of a stone, brick or piece of wood. Once scanned, a mold can be produced from a suitable mold material for mass manufacture of the front panels or fascias having a front surface supporting the scanned image. It is noted that the core side of the mold may be produced by either digitally scanning or casting the natural surface. Such imaging provides a core that will substantially mirror the front surface of the mold and thereby provide a manufactured panel  10  that is relatively uniform in thickness. 
         [0079]    As previously mentioned the panels of the present invention may take on the image of a single stone, brick or piece of wood. Alternatively, as depicted in  FIGS. 5   a - c , the veneering panel  10  may have the appearance of multiple stones. For example, a single panel may appear as a ledgestone configuration having a plurality of cut stones as depicted in  FIG. 5   a . In yet another embodiment, as depicted in  FIGS. 5   b  and  5   c  the veneering panel  10  may appear to include a plurality of field stones or a plurality of cut stones in a random Ashlar pattern. Additionally, as previously suggested, the front surface  12  may include one or more colors, textures and/or degrees of relief to provide a natural stone, brick or wood appearance. 
         [0080]    When covering a wall with panels that have the image of multiple items, such as stones, wood or brick, it is important to avoid the appearance of a reoccurring pattern. When utilizing such products it is not uncommon that visually unacceptable straight lines are formed when individual items, such as stones, are aligned, thereby forming long vertical or horizontal breaks in the wall wherein a series of stones or wood planks end in the same location. Such breaks are perceived as being an unacceptable pattern. Therefore, embodiments of the present invention are designed to provide imaged items, such as stones, brick or wood planks, in positions which break designated fields or planes. In such embodiments, individual stones are positioned on a majority of the panels (e.g. &gt;50% of the panels or in other embodiment &gt;75% of the panels) so as to break at least two or more fields/planes that extend partially along the perimeter of the panel, but also pass through the interior of the panel. In other embodiments of the present invention, individual stones are positioned on a majority of the panels (e.g. &gt;50% of the panels or in other embodiment &gt;75% of the panels) so as to break at least three or more fields/planes that extend partially along the perimeter of the panel, but also pass through the interior of the panel. In yet other embodiments of the present invention, individual stones are positioned on a majority of the panels (e.g. &gt;50% of the panels or in other embodiment &gt;75% of the panels) so as to break at least four or more fields/planes that extend partially along the perimeter of the panel, but also pass through the interior of the panel. If such fields are not broken by a strategically placed stone a reoccurring break pattern on the wall may become recognizable. 
         [0081]      FIG. 5   a  depicts a T-unit panel  10  that includes four fields or planes that extend along the periphery of the panel  10 , but also pass through the interior of the panel. In the T-Unit depicted in  FIG. 5   a  at least one individual stone is found to break each of the four fields. The fields are designated by dashed lines and the field breaks are outlined with boxes. For example, stone  2  breaks field  1 ; stone  4  breaks field  2 ; stone  3  breaks field  3  and stones  3  and  5  break field  4 . 
         [0082]      FIG. 5   b  depicts another embodiment of the present invention wherein individual imaged items, such as stones, are positioned on a Z-unit panel  10 . The Z-unit panel of this embodiment generally has 3 fields/units wherein one or more imaged items breaks each of the fields. For example, stone  1  breaks field  1 ; stone  2  breaks field  3  and stone  3  breaks field  2 . The fields are designated with dashed lines and the breaks are designated in the boxes. Finally,  FIG. 5   c  depicts a partial wall having at least 4 different Z-unit panels  1 ,  2 ,  3 ,  4  and a few finishing panels A, B, C, D and I, II, III. As can be seen in the wall, a wall constructed utilizing a majority of panels that break the fields avoid the unacceptable straight line breaks in the wall. 
         [0083]    Various embodiments of the panels of the present invention may further include interlocking members that allow the panels to overlap and/or secure to each other.  FIG. 6   a  depicts one embodiment of the present invention wherein the panel  10  includes a front overlap  30  and a back overlap  32 . It is noted that such interlocking panels may also be found on the sides of the panels  10  rather than or in addition to being positioned on the top and bottom of the panels  10 . Additionally, the front overlap  30  and back overlap  32  may have fastening devices to mechanically interconnect the panels to each other. Examples of fastening devices include, but are not limited to snaps, peg and slots, clips, adhesives, screws, rivets, nails and combinations thereof.

         [0113]    The panels of the present invention may take the form of any shape and may be of any size. For example, as previously mentioned, the panel may be shaped in a rectangle, circular, elliptical or “Z” configuration. Panels may also be shaped to wrap around corners or fit into or onto irregular shapes.  FIGS. 29 and 30  depict two embodiments of corner panels  64  that can be utilized in outside and inside 90 degree corners. 
         [0114]    The panels  10  and corner panels  64  may also be of varying size. In some embodiments of the present invention the panels  10  are greater than eight square feet. In yet other embodiments of the present invention the panels  10  are approximately two to eight square feet. In still other embodiments the panels  10  are approximately ¼ to four square feet or are ½ to 3 square feet. Additionally different size panels may be utilized to provide an irregular pattern (e.g. Ashlar or ledgestone patterns). 
         [0115]    As previously identified, any wall may be covered with the veneering product of the present invention. For example, segmental retaining wall block may be adapted to accept and secure a veneering panel of the present invention. Such a panel would provide additional durability, deterioration resistance and aesthetic appearance to the normally problematic concrete product.  FIGS. 31   a - e  depict one embodiment of the panel  10  that may be utilized to cover a concrete block. The panel  10  of this embodiment of the present invention, generally includes a front face  12  adjoined to one or more groove attachments  96 . The front face  12  may be molded and/or fabricated as described herein to include a colored and textured surface that replicates a natural appearances, such as stone or wood. For example, in various embodiments of the present invention, a stone or wood plank may be imaged to capture the desired face and then coated with one or more polymer paints to capture the natural appearance. It is noted that other fabrication processes, such as in-mold decoration or solid surface coating, may be utilized in manufacturing the block panels of the present invention. In this embodiment, the panel  10  may extend around the side of a concrete block  100  wherein the one or more groove attachments  96  are configured to insert and secure into a groove  98  positioned on the concrete block  100 . The groove attachments  96  and accepting grooves  98  may be of a variety of shapes and sizes. 
         [0116]    Another example of a panel  10  that may be utilized to cover concrete blocks is depicted in  FIGS. 32   a - c . In this embodiment, the groove  98  and groove attachment  96  are in the shape of a dove tail or dogbone, thereby providing for the secure attachment of the panel  10 .  FIG. 32   b  depicts the back view of a panel that includes two groove attachments  96  that are shaped in a dogbone configuration and a panel  10  that includes wrap around edges  102 . 
         [0117]    Each of the panels of the present invention may be textured and include color and/or other additives (e.g. U.V. inhibitor, texture enhancer, metal or glass particulates and the like) to provide protection to the panels and/or provide the desired natural appearance. Generally, the surface visible to the observer will include a molded and/or fabricated texture and/or pattern in the deterioration resistant material. In various embodiments of the present invention the exposed surface of the panel  10  will have a natural appearance. For example, the exposed surface of the front surface  12  may be textured and colored to have the appearance of rock, natural stone, sand, soil, clay, wood, trees and foliage, water, or any other natural earthen appearance. Additionally, in other embodiments, the exposed surface of the veneering product, such as the front surface  12  may further include one or more designs (e.g. symbols, company names, logos, images) that may be positioned in the natural appearance texture and color (e.g. a company logo embedded in a stone color and texture). Also, in other embodiments of the present invention, the front surface  12  may further include a design, such as the appearance of multiple bricks, stones, timbers or blocks. This allows for the installation of larger panels in a wall that appear to include a multitude of bricks, stones, blocks, timbers and the like. 
         [0118]    In many embodiments of the present invention, the appearance of the front surface  12  the other portions of the panel  10  that are intended to be seen, generally include a natural appearance. This may be accomplished in a number of ways including but not limited to thermal molding, lamination and/or coating (e.g. solid surface coating, such as U.V. activated coating, or polymer painting). For example, the relief, texture and color of each panel  10  may be formed by thermal molding one or more resins that include colors and other additives in a mold that has a desired texture. Such a process may be performed by any process known in the art, such as thermoforming, extrusion, rotomolding, injection molding, structural foam molding, injection molding using chemical and other foaming agents, vacuum molding or any combination thereof. In many embodiments of the present invention the panels  10  are formed using a foamed process, such as structural foam molding or injection molding using foaming agents. Such parts made by using a foamed process provides a part that is durable, rigid and possesses a desirable texture. In other embodiments, the texture may also be imprinted on the panel  10  in a secondary process after formation of the panel  10  by rolling a die that imprints the texture on the polymeric front surface  12 . 
         [0119]    In other embodiments of the present invention, the natural appearance can be achieved through a lamination process. In various embodiments, a sheet of polymeric material having the desired natural appearance and including the desired color and additives (e.g. UV inhibitor, natural or synthetic stone particles . . . ) is laminated over the portions of the panel  10 , such as the front face  12 . In various embodiments of the present invention a sheet of polymeric material may include natural or synthetic particles (e.g. granite, marble, aluminum trihydrate, aluminum oxide . . . ). Generally, in the lamination process, the front surface  12  may have a sheet of polymeric material heat welded or adhered to the front surface  12 . Such a lamination step may happen in a secondary step after formation of the panel  10 . Alternatively, the laminated plastic sheet may be inserted into the front side of a mold and formed over the resin that is administered into the mold. For example, a sheet of polymeric material may be placed in the front end of an injection molding mold and subsequently thermoformed or vacuum formed to the front surface of the mold prior to filling the mold with resin when manufacturing the panel  10 . Next, melted resin is shot into the injection mold, thereby integrating the laminated sheet into the front of the panel  10  and optionally top of the other parts of the panel  10  intended to be seen. 
         [0120]    In yet other embodiments of the present invention, the natural appearance may be achieved by utilizing a solid surface coating. The solid surface coating generally includes one or more natural mineral or fiber fillers, one or more polymeric binder resins and one or more initiators. The natural mineral or fiber fillers may include but are not limited to natural stone or rock filler (e.g. granite, marble, quartz, limestone, shale particles), wood fiber, hydrated alumina (e.g. aluminum trihydrate), ground silica, acrylic chips, calcium carbonate, aluminum oxide with pigmented polymer coated quartz, sand, and any other filler that would provide a natural stone, brick or wood appearance. 
         [0121]    Various embodiments of the present invention include one or more polymerizable binder resins. In one embodiment, the present invention provides a system comprising initiators and one or more polymerizable binder resins, each binder resin bearing one or more polymerizable groups. In accordance with this embodiment, the photoinitiator group serves to initiate polymerization of the polymerizable groups, thereby forming a polymeric coating, e.g., in the form of a layer covalently bound to the front surface of the panel via the one or more initiators. As used herein, “polymerizable group” shall generally refer to a group that is adapted to be polymerized by initiation via free radical generation, and more preferably by photoinitiators activated by visible or long wavelength ultraviolet radiation. 
         [0122]    Suitable polymerizable compounds are selected from monomeric polymerizable molecules (e.g., organic monomers), and macromeric polymerizable molecules (e.g., organic macromers). As used herein, “macromer” shall refer to a macromolecular monomer having a molecular weight of about 250 to about 25,000, and preferably from about 1,000 to about 5,000. For purposes of the present invention, and unless specified otherwise, the term “monomer” when used in this respect shall generally refer to monomeric and/or macromolecular polymerizable molecules. 
         [0123]    In yet another embodiment, the polymerizable monomer compounds of the present invention comprise macromeric polymerizable molecules. Suitable macromers can be synthesized from monomers such as those illustrated above. According to the present invention, polymerizable functional components (e.g., vinyl groups) of the macromer can be located at either terminus of the polymer chain, or at one or more points along the polymer chain, in a random or nonrandom structural manner. 
         [0124]    Examples of some polymerizable binder resins that may be utilized in the present invention include, but are not limited to, polyurethanes, polyepoxides, epoxy-acrylates, epoxide and epoxy resins, urethane acrylates, methacrylates, unsaturated polyesters, polyols, acrylics and monomers and oligomers having similar backbone structures of these resins. 
         [0125]    The coatings also include one or more initiators. Generally the initiators are polybifunctional reagents of the invention carry one or more pendent latent reactive (e.g. photoreactive or thermoreactive) moieties covalently bonded to the resin. Various embodiments of the coatings of the present invention include one or more photoreactive moieties that are sufficiently stable to be stored under conditions in which they retain such properties. Latent reactive moieties can be chosen that are responsive to various portions of the electromagnetic spectrum, with those responsive to ultraviolet and visible portions of the spectrum (referred to herein as “photoreactive”) being particularly preferred. 
         [0126]    Photoreactive moieties respond to specific applied external stimuli to undergo active specie generation with resultant covalent boding to an adjacent chemical structure, e.g., as provided by the same or a different molecule. Photoreactive moieties are those groups of atoms in a molecule that retain their covalent bonds unchanged under conditions of storage but that, upon activation by an external energy source, form covalent bonds with other molecules. 
         [0127]    The photoreactive moieties generate active species such as free radicals and particularly nitrenes, carbenes, and excited states of ketones upon absorption of external electric, electromagnetic or kinetic (thermal) energy. Photoreactive moieties may be chosen to be responsive to various portions of the electromagnetic spectrum, and photoreactive moieties that are responsive to e.g., ultraviolet and visible portions of the spectrum are preferred and are referred to herein occasionally as “photochemical” moiety. 
         [0128]    Photoreactive aryl ketones, such as acetophenone, benzophenone, anthraquinone, anthrone, and anthrone-like heterocycles (i.e., heterocyclic analogues of anthrone such as those having N, O, or S in the 10-position), or their substituted (e.g., ring substituted) derivatives are utilized in some embodiments of the present invention. The functional groups of such ketones are preferred since they are readily capable of undergoing the activation/inactivation/reactivation cycle described herein. Benzophenone is one photoreactive moiety that may be utilized, since it is capable of photochemical excitation with the initial formation of an excited singlet state that undergoes intersystem crossing to the triplet state. The excited triplet state can insert into carbon-hydrogen bonds by abstraction of a hydrogen atom (from a support surface, for example), thus creating a radical pair. Subsequent collapse of the radical pair leads to formation of a new carbon-carbon bond. If a reactive bond (e.g., carbon-hydrogen) is not available for bonding, the ultraviolet light-induced excitation of the benzophenone group is reversible and the molecule returns to ground state energy level upon removal of the energy source. Photoactivatable aryl ketones such as benzophenone, thioxanthone, camphorpyinone and acetophenone are of particular importance inasmuch as these groups are subject to multiple reactivation in water and hence provide increased coating efficiency. 
         [0129]    Other initiator may include one or more photointiated reagents including four or more reactive groups. Examples of such initiators include tetrakis (4-benzoylbenzyl ether), the tetrakis (4-benzoylbenzoate ester) of pentaerythritol, and an acylated derivative of tetraphenylmethane. 
         [0130]    The azides constitute another class of latent reactive moieties and include arylazides (C 6 R 5 N 3 ) such as phenyl azide and particularly 4-fluoro-3-nitrophenyl azide, acyl azides (—CO—N 3 ) such as benzoyl azide and p-methylbenzoyl azide, azido formates (—O—CO—N 3 ) such as ethyl azidoformate, phenyl azidoformate, sulfonyl azides (—SO 2 —N 3 ) such as benzenesulfonyl azide, and phosphoryl azides (RO) 2 PON 3  such as diphenyl phosphoryl azide and diethyl phosphoryl azide. Diazo compounds constitute another class of photoreactive moieties and include diazoalkanes (—CHN 2 ) such as diazomethane and diphenyldiazomethane, diazoketones (—CO—CHN 2 ) such as diazoacetophenone and 1-trifluoromethyl-1-diazo-2-pentanone, diazoacetates (—O—CO—CHN 2 ) such as t-butyl diazoacetate and phenyl diazoacetate, and beta-keto-alpha-diazoacetates (—CO—CN 2 —CO—O—) such as t-butyl alpha diazoacetoacetate. Other photoreactive moieties include the aliphatic azo compounds such as azobisisobutyronitrile, the diazirines (—CHN 2 ) such as 3-trifluoromethyl-3-phenyldiazirine, the ketenes (—CH═C═O) such as ketene and diphenylketene. 
         [0131]    The solid surface coating may be applied to the surface of the veneering product of the present invention by any type of process that would provide substantial coverage of the product surface and secure attachment of the coating, such as spray coating, dip coating and the like. In various embodiments of the present invention, the solid surface coating may be administered to the product surface in a one step or two step process. For example, in a one step process, a substantially homogenous mixture of the filler, polymerizable resin and initiators are administered to the surface of the product and the initiators then subsequently activated to polymerize the resin and attach the coating to the surface. 
         [0132]    Alternatively, a two step or grafting process may be utilized to administer the solid surface coating. In such a process, the initiator is first administered to the surface and activated to attach the initiator to the surface. Once the initiator is attached, a substantially homogenous mixture of the filler and polymerizable resin is administered to the surface and the initiator is again activated to polymerize the resin and attach the mixture to the surface. It is noted that in various embodiments of the present invention, a tie-in layer may be applied to the surface to facilitate better attachment of the solid surface coating. For example, one or more layers, such as a silane, siloxane and/or Parylene layer(s) may be applied to the surface prior to administration of the solid surface coating. 
         [0133]    In other embodiments of the present invention, the veneering products may be colored and further textured utilizing a painting process. One such painting process that may be used with various embodiments of the present invention is a polymer adhesion painting process wherein a polymer adhering paint is applied to the surface of the veneering product. In some embodiments of the present invention the polymer adhering paint is applied to the front surface  12  after the front surface  12  has been flame treated or plasma or corona treated. Alternatively, adhesion promoters may be utilized to promote adhesion of the polymer paints rather than flaming, plasma or corona treatment. However, it is noted that the adhesion promoter may be included in the base coat or may be the base coat applied to the front surface  12 . 
         [0134]    In various embodiments of the present invention the polymer adhering paint may be a solvent or water based paint. Examples of such paints are identified below. However, many of the embodiments of the present invention utilize a polymer adhering paint that has a very low gloss. For example, in embodiments of the present invention the gloss rating of the paint utilizing a 60° gloss meter is less than 5 and may be between 0 and 4. In various embodiments the gloss is between 1 and 3. 
         [0135]    In one polymer adhesion painting method, the front surface  12  of the panel  10  is manufactured utilizing a process, such as injection molding, structural foam molding (e.g. low pressure multi-nozzle structural foam), injection molding using chemical and other foaming agents, rotomolding, thermoforming, extrusion or any other process. Next, all surfaces of the panel  10  intended to be painted may be flame treated, plasma or corona treated or treated with adhesion promoter prior to applying paint. The flame treating may be performed with any gas torch system, such as propane, acetylene and the like. Plasma treatment may also be performed by any device that forms a gas plasma that can be directed to the polymeric surface. The flame or plasma treated surface should be painted within 24 hours, optionally within 8 hours and further optionally within 5 hours. Once the surface has been flame, plasma, corona, or adhesion promoter treated, a polymer adhering paint, such as a polyurethane based paint mixed with a crosslinker or a waterbase paint is applied to the surface or surfaces of the panel  10 . It is noted that the polymer adhering paint mixture should be applied shortly after mixing; in some embodiments almost immediately. 
         [0136]    One example of the types of polymer paints that may be utilized with embodiments of the present invention is a two-component polyurethane that generally includes a mix ratio of three to five parts colored paint with one to two parts crosslinker (e.g. XL-003 crosslinker or an isocynate). Two examples of two such polyurethane based paints are as follows:

Both polymer adhesion paints of Examples 3 and 4 are manufactured and distributed by:
 
       United Paint, Inc. 
     24671 Telegraph Road 
     Southfield, Mich. 48033-3035

         [0144]    The polymer adhering paints may further include one or more additives to provide additional beneficial characteristics. For example, additional texture may be applied to the surface of a panel  10  by including additives to the paint in fine, medium or course particulate form. Such particulate additives may be selected from any suitable texture additives such as mica, sand, perlite, pumice, silica, metal, acrylic or glass beads and fibers, or any other paint texture additive. The paint additives may be included in the paint or applied in the painting process. For example, paint textures such as mica, sand, pumice and the like may be propelled (e.g. propelled toward the surface using a device, such as a sandblaster) or sifted (e.g. sprinkled onto the surface using a sieve) onto the surface of the panel while simultaneously applying the base coat and/or secondary coat(s) of paint. Such a process disperses and entraps the texture in the coating, thereby giving a fine, medium or course textured surface. 
         [0145]    The polymer adhesion paints may be applied in any manner known in the art including, but not limited to, spraying, dipping, brushing, sponging and any other paint application method. In various embodiments polymer adhesion paint is applied by spraying. Generally, less than 10 mils of paint are applied to the surface intended to be painted. In other embodiments less than 5 mils of paint is applied and in other embodiments less than 5 mils of paint is applied to the surface intended to be painted. In various examples, approximately 0.2 to 2.5 mils or 0.5 to 1.5 mils dry film thickness of base color was applied to the entire surface of panels. Once the base paint has been applied, secondary colors may optionally be applied to the wet or dry base coat as desired. Such secondary colors may be applied in similar ways as the base paint, such as spraying, dipping, brushing, sponging and any other spray technique known in the art. It is also noted that a primer layer may be applied to the substrate surface prior to applying the paints described herein. For example, a coating of binel, parylene or another primer coat may be applied to the surface prior to applying the paint to promote optimum adhesion. 
         [0146]    Once the paint has been applied to the desired surface of the veneering panels, the product is then cured. In various embodiments of the present invention, the product is oven cured following painting at a temperature of 220° F. and less (e.g. 175° F. to 220° F.); in other embodiments 185° F. and less (e.g. 150° F. to 185° F.); and in still other embodiments 160° F. and less (e.g. 100° F. to 150° F.). In various embodiments the paint, is cured at the above mentioned temperatures for a period of 2 minutes to 4 hours; in other embodiments 5 minutes to 2 hours and in still other embodiments 5 minutes to 30 minutes. The product is then allowed to air dry. Once air dried, the veneering products are ready for installation. It is noted that the curing process may be performed at room temperatures, but the curing time usually will be lengthened accordingly. 
         [0147]    Again, as previously mentioned the solid surface coating, a polymeric sheet or polymer adhesion paint may be administered or laminated to any veneering product comprised of a deterioration resistant material (e.g. plastic resin, thermoset, fiberglass, etc.). In such embodiments, the solid surface coating, polymeric sheet or polymer adhesion paint is applied to one or more surfaces of the veneering product. 
         [0148]    As previously mentioned, the veneering products of the present invention may be manufactured from a deterioration resistant, substantially rigid composite or polymeric material including, but not limited to, plastic (e.g. recycled or virgin), a rubber composition, fiberglass, or any other similar material or a combination thereof. Preferable materials comprise light-weight and slightly flexible polymers, such as high and low density polyethylene (HDPE or LDPE) and polypropylene (PP). It is noted that a polypropylene copolymer may be utilized with the present invention, but it is recommend that the polypropylene copolymer have a polyethylene content no greater than 30% polyethylene and in other embodiments no greater than 20% polyethylene. However, other plastics may also be used. Examples of other plastics include, but are not limited to acrylonitrile-butadiene-styrene (ABS), poly(butylene terephthalate) (PBT), poly(cyclohexanedimethylene terephthalate) (PCT), styrene-acrylonitrile copolymers (SAN), polystyrene, polycarbonate, polyvinyl chloride (PVC), polyurethane, copolymers and combinations thereof. It is also noted that the deterioration polymeric materials may also be utilized with filler materials or recycled filler materials, such as titanium, carbon fibers, talc, glass, saw dust, cellulose fibers, paper byproducts and the like. Generally, the embodiments of the present invention may comprise any type of material that would have the similar characteristics to plastic, vinyl, silicone, fiberglass, rubber or a combination of these materials. 
         [0149]    One other material that may be utilized with the present invention may be a thermoset. For example, a bulk molding compound (BMC) or thermoset that includes one or more polyester resins, glass fibers and other additives may be utilized to manufacture one or more components of the present invention. Various embodiments of thermosets and BMC is manufactured and/or molded by Bulk Molding Compounds, Inc. 1600 Powis Court West, Chicago Ill. 60185 and Kenro Incorporated, a Carlisle Company, 200 Industrial Drive, Fredonia, Wis. 53021. 
         [0150]    It is noted that the material utilized in the present invention should be rigid enough to hold its form upon installation, impact and/or when placed in contact with other objects. Another material may be comprised of a material similar to that utilized in the production of some types of garbage cans or the utilization of recycled rubber from objects such as tires. Such materials would be capable of holding rigidity and still offer flexibility upon impact. Also, such materials have the ability to regain its original form when the impact force has been removed or completed. 
         [0151]    Embodiments of the present invention may also vary in appearance. Since embodiments of the present invention may be manufactured by a process such as injection molding, structural foam molding, injection molding using chemical and other foaming agents, extrusion, thermo-forming, compression molding, roto-molding and the like, the molds may include any type of design, size and shape. Furthermore, the front surfaces  12  of the panels  10  could be molded in almost any type of texture, relief and/or configuration. For example, the panels may be designed to appear like a plurality of field stones, cut stones, bricks, wood planks, or any other natural wall construction material. In other embodiments, multiple panels  10  could be molded to include designs that, when positioned on a retaining wall, would complete a larger single design, such as the spelling of a company or school name in large letters or the completion of a large image. It is noted that embodiments of the present invention may also be used in conjunction with other wall products, such as vinyl siding, bricks, stones and the like. 
         [0152]    Furthermore, since the present invention may be manufactured from and/or include a number of different products, such as plastic, a rubber composition or fiberglass, the panels may include any color or a multitude of colors. The utilization of any color or a multitude of colors in the veneering products of the present invention allows ease in matching colors with the conventional wall building materials or surroundings because the materials utilized to manufacture the present invention can be colored and designed to match virtually any type of wall construction material or surrounding environment. For example, the panels of a wall installed in a beach setting may be manufactured of a plastic or rubber product and be colored to take on the appearance of sand or natural stone walls. 
         [0153]    As previously suggested the veneering product of the present invention may be utilized in the construction of any type of wall or surfacing project wherein a natural appearance, such as stone, brick or wood, is desired. In application, a substrate surface may be veneered with various panel  10  embodiments of the present invention by applying one or more of the panels to a surface of a substrate. In a number of embodiments of the present invention the process begins by preparing the substrate to be resurfaced by cleaning the substrate surface. The substrate surface may be a wall, such as an existing wall that is substantially planar and made of one or more materials, such as wood, drywall, masonry, sheathing, sheet metal, insulation (e.g. foam insulation), poured concrete, cinder and concrete block, segmental retaining wall block, brick and the like. In other embodiments, the substrate may be prepared by securing a grid system or backing to the substrate surface. Upon identifying the substrate, one or more panels are administered to the surface of the substrate or an attached grid system or backing previously applied to the substrate surface. 
         [0154]    In various embodiments of the present invention a pattern can first be placed on the substrate surface to be covered with panels of differing shapes. For example, a pattern, such as an Ashlar pattern may be applied to the wall by a rubbing or stencil, thereby leaving an image of the desired placement positions of the various shaped panels. Once the stencil pattern is administered to the wall or surface, the equivalent shaped and sized panel is applied to the pattern similar to the placement of puzzle pieces in a jigsaw puzzle. It is noted that more than one pattern may be applied to the same wall thereby giving a random final appearance. 
         [0155]    The panels of the present invention may be administered to the surface or the grid system or backing by one for more fasteners, such as adhesives, rivets, screws, nails, two sided tapes, ball and socket attachments, snaps, hook and pile attachments, sliding brackets, clipping devices (e.g. barb clip and radius clips) sliding brackets, structural VELCRO® or other attachment means known in the art that would secure the panels of the present invention to the substrate or grid system or backing. It is noted that combinations of the fasteners may also be utilized to secure the panels of the present invention. For example, various embodiments may utilize a combination of screws, nails or rivets with one or more adhesives to secure the panels to a substrate or the grid system or backing. 
         [0156]    In a number of embodiments of the present invention each panel is adhered to the substrate and/or adjacent panel with a two sided tape that includes an adhesive that has an affinity to polymeric materials. For example various embodiments of the panels may be secured with adhesives, such as the two sided VHB and acrylic or polyurethane foam tapes produced by 3M. In such embodiments of the present invention, the two sided tape may be adhered to the attachment platforms on the back surface of each panel. The backing of the two sided tape is removed and the panel is attached to the wall or substrate in the desired location. Examples of such tapes that may be utilized with the panels  10  of the present invention include 4952, 5952, 5925 and 5962 VHB two sided adhesive tapes manufactured by 3M, 3M Center, St. Paul, Minn. 55144-1000. Another adhesive tape that may be utilized includes, but is not limited to, the 4466W Double Coated Polyethylene foam tape manufactured by 3M. Other examples of suitable two sided tapes that may be utilized with the panels of the present invention include, but are not limited to, 3M® Double Coated Polyethylene Foam Tape 4492W and 4462W, 3M® VHB® Acrylic Foam Tape 5952 and 5925 and 3M® Double Coated Urethane Foam Tape 4016. Additionally adhesive sealants, such as the 4000 and 5200 sealants produced by 3M may also be used to secure the panels  10  to a substrate, such as a wall. The sealants may be applied on the substrate surface or on the back surface of the panel prior to pressing the panel to the surface of the substrate by any means known in the art (e.g. spraying or spreading). However, it is important that the adhesive (e.g. tape or sealant) utilized be appropriate to adhere a resin based product. The examples listed above provide this feature. In general, the curing of the adhesive properly affixes the panel to the substrate. Curing times vary depending on the adhesive, but many will cure within less than 72 hours. 
         [0157]    While the invention has been illustrated and described in detail in the drawings and foregoing description, such an illustration and description is to be considered as exemplary and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
