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.
