Wall patch

Abstract

A wall patch for repairing a dent, a hole, a crack or another flaw in a wall includes two thin sheets. One of the sheets is a lower sheet for adhesion to the wall in such a manner that the sheet covers the flaw. The other sheet is an upper sheet for adhesion to the wall in such a manner that it covers the lower sheet. The lower sheet is smaller in area and stronger than the upper sheet. The upper sheet has an irregularly corrugated edge and an upper surface rough in texture with a matted or (satin-)embossed pattern, which is similar to the surface texture of the wall.

What is claimed is:  
     
         1 . A wall patch for repairing a dent, a hole, a crack or another flaw in a wall, comprising: 
 a lower thin sheet for adhesion to the wall in such a manner that the sheet covers the flaw; and    an upper thin sheet for adhesion to the wall in such a manner that the upper sheet covers the lower sheet;    the lower sheet being smaller in area and stronger than the upper sheet;    the upper sheet having an irregularly corrugated edge.    
     
     
         2 . A wall patch according to  claim 1 , further comprising a boundary erasing agent for erasing the boundary between the upper sheet and the surrounding wall surface by being applied to an area along the boundary.  
     
     
         3 . A wall patch according to  claim 1 , wherein the upper surface of the upper sheet has a rough texture with a matted or (satin-)embossed pattern, which is similar to the surface texture of the wall.  
     
     
         4 . A wall patch according to  claim 3 , further comprising a boundary erasing agent for application to an area along the boundary between the upper sheet and the surrounding wall surface, and for foaming with heat to provide a rough texture having a matted or embossed pattern.  
     
     
         5 . A wall patch for repairing a dent, a hole, a crack or another flaw in a wall, comprising: 
 an upper sheet for adhesion to the wall in such a manner that the sheet covers the flaw, the upper sheet having an irregularly corrugated edge and an upper surface rough in texture with a matted or (satin-)embossed pattern, which is similar to the surface texture of the wall; and    a boundary erasing agent for application to an area along the boundary between the upper sheet and the surrounding wall surface, and for foaming with heat to provide a rough texture having a matted or embossed pattern.    
     
     
         6 . A wall patch for repairing a dent, a hole, a crack or another flaw in a wall, comprising: 
 a first sheet for adhesion to the wall in such a manner that the sheet covers the flaw; and    a second sheet that can have a rough texture with a matted or (satin-)embossed pattern, which is similar to the surface texture of the wall.    
     
     
         7 . A wall patch according to  claim 6 , wherein the first sheet is a lower sheet that is a strong sheet for adhesion to the wall in such a manner that the sheet covers the flaw, and wherein the second sheet is an upper sheet that is larger in area than the lower sheet and has an irregularly corrugated edge.  
     
     
         8 . A wall patch according to  claim 6 , wherein the second sheet has a color or a pattern similar to the color or pattern of the surrounding wall surface.  
     
     
         9 . A wall patch according to  claim 6 , wherein the second sheet is made of paper or plastic with suitable surface roughness that allows the second sheet to be colored or have a pattern.  
     
     
         10 . A wall patch according to  claim 7 , wherein the lower sheet is an acrylic sheet, a resin sheet, a glass fiber sheet, a metal sheet, or a strong sheet of paper.  
     
     
         11 . A wall patch for repairing a dent, a hole, a crack or another flaw in a wall, comprising: 
 a lower sheet that is a strong sheet for adhesion to the wall in such a manner that the sheet covers the flaw; and    an upper sheet for adhesion to the wall in such a manner that the upper sheet covers the lower sheet, the upper sheet being larger in area than the lower sheet.    
     
     
         12 . A wall patch according to  claim 11 , wherein the lower sheet has an irregularly corrugated edge.  
     
     
         13 . A wall patch according to  claim 11 , further comprising a boundary erasing agent for erasing the boundary between the upper sheet and the surrounding wall surface by being applied to an area along the boundary.
