       BRIEF SUMMARY  
       [0009]     As will be described below, important aspects of the invention reside in the field of finishing wet plaster. In order to achieve a smooth finish, which will not peel or roll, water must be applied to the wet plastered surface and smoothed over the wet plaster. The result is an even, smooth, professional finish, which will not peel or roll.  
         [0010]     In accordance with one embodiment of the invention, a device for finishing a wet plaster surface is provided. The device is a brush having an brush head attached to a handle. The handle is attached to a base. The base has a rectangular cavity wherein the original brush head is partially contained within the rectangular cavity and may partially protrude beyond the cavity.  
         [0011]     The cavity has a brush receiving surface, a first brush receiving side wall, and a second brush receiving side wall. The brush receiving surface has a slot to receive the brush handle. The first brush receiving side wall is connected to the brush receiving surface. The second brush receiving side wall is connected to the brush receiving surface.  
         [0012]     Preferably, at least one additional brush head is attached to the brush receiving surface and protrudes beyond the cavity.  
         [0013]     In another embodiment, the cavity also has a brush receiving front wall and a brush receiving back wall. The first brush receiving side wall is also connected to the brush receiving front wall and the brush receiving back wall. The second brush receiving side wall is also connected to the brush receiving front wall and the brush receiving back wall. The brush receiving front wall is connected to the brush receiving surface, the first brush receiving side wall, and the second receiving side wall. The brush receiving back wall is connected to the brush receiving surface, the first brush receiving side wall, and the second receiving side wall.  
         [0014]     In another embodiment, the brush heads are manufactured out of a disposable material, so that they need not be cleaned. They are disposed of after each use, and replaced prior to each application.  
         [0015]     In another embodiment, the handle has finger grooves to facilitate gripping.  
         [0016]     In another embodiment, the handle has a thumb pad to facilitate pressure application.  
         [0017]     In another embodiment, the device is a brush having an original brush head attached to a base. The base has a cavity where the original brush head is partially contained within the cavity and partially protrudes beyond the cavity.  
         [0018]     The cavity has a brush receiving surface, a first brush receiving side wall, and a second brush receiving side wall. The first brush receiving side wall is connected to the brush receiving surface. The second brush receiving side wall is connected to the brush receiving surface.  
         [0019]     Preferably, at least one additional brush head is attached to the brush receiving surface and protrudes beyond the cavity.  
         [0020]     In another embodiment, the base has finger and thumb groves to facilitate gripping.  
         [0021]     In another embodiment, the device is a wide banded brush of at least 12 inches in length.

     DETAILED DESCRIPTION  
       [0027]     Referring to  FIG. 1  there is shown a pictorial diagram of a device  1  used to finish wet plaster. The device is a brush having an brush head  2  attached to a handle  3 . The handle  3  is attached to a base  4 . The handle  3  is a soft material which molds to the user&#39;s hand allowing for a better grip without causing fatigue during extended use. Referring to  FIG. 2 , the base  4  has a cavity  6  where the original brush head  2  is partially contained within the cavity  6  and partially protruding beyond the cavity  6 . The cavity  6  has additional brush heads  5   a  and  5   b  in addition to the original brush head  2 . Brush heads  5   a  and  5   b  protrude beyond the cavity  6 .  
         [0028]     Referring to  FIG. 3 , the cavity  6  has a brush receiving surface  11 , a first brush receiving side wall  7 , a second brush receiving side wall  8 , a brush receiving front wall  9  and a brush receiving back wall  10 . The brush receiving surface  11  has a slot  12  to receive the brush handle  3 . The first brush receiving side wall  7  is connected to the brush receiving surface  11 , the brush receiving front wall  9 , and the brush receiving back wall  10 . The second brush receiving side wall  8  is connected to the brush receiving surface  11 , the brush receiving front wall  9 , and the brush receiving back wall  10 . The brush receiving front wall  9  is connected to the brush receiving surface  11 , the first brush receiving side wall  7 , and the second receiving side wall  8 . The brush receiving back wall  10  is connected to the brush receiving surface  11 , the first brush receiving side wall  7 , and the second receiving side wall  8 .  
         [0029]     Referring to  FIG. 4 , the handle has finger grooves  21   a  and  21   b  to facilitate gripping. The handle has thumb pads  22   a  and  22   b  to facilitate pressure application. The brush  20  is a wide banded brush of at least 12 inches in length. It will be appreciated that any suitable number of brush heads of suitable width may be used. For example, three brush heads, each four inches wide may be used. This arrangement would allow for the independent replacement of brush heads where brush heads are subject to the same wearing. In other words, the center brush head, is not likely to be subject to the same wear as the outer brush heads.  
         [0030]     Referring to  FIG. 5 , the device  30  is a brush having an original brush head  31  attached to a base  32 . Additional brush heads  33   a  and  33   b  are attached to the brush receiving surface (not shown) and protrudes beyond the cavity. The base  32  has finger groves  34   a  and  34   b  and thumb grove  35  to facilitate gripping.  
         [0031]     An advantage of the present invention results in a more professional finish on walls which have been wet plastered. This finish is more even, smoother and will not peel or roll.
