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.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to wall patches in particular for repairing holes, dents, cavities or other flaws in wall surfaces.[0003] 2. Description the Related Art[0004] Wall surfaces in a building are usually finished beautifully with paint or wallpaper. In case such a wall surface sustains damage due to holes or cracks, it would be more economically restored if the flaws could be repaired selectively instead of reworking the entire wall face.[0005] With respect to prior arts of wall repair commercially available, there is a patching compound or putty disclosed in Japanese Utility Model Laid-Open Publication No. 6-83862, for example. This mending putty is used to restore the original wall plane by filling the putty of a color similar to the wall color into the holes or dents in the wall face.[0006] Other types of means for wall repair include mending sheets cut out into suitable sizes. These sheets are supplied in colors similar to the wall...

AI Technical Summary

Benefits of technology

[0012] Another object of the present invention is to provide a wall patch capable of sufficiently concealing the boundary between its patching sheet and the surrounding surface of a wall.

[0013] Still another object of the present invention is to provide a wall patch capable of almost or nearly concealing the boundary between its patching sheet and the surrounding surface of a wall having a matted or (satin-)embossed rough surface texture.

[0015] This wall patch makes it possible to repair the flaw with the two sheets simply and quickly without skill. The double-ply patch is thinner as a whole and makes it possible to repair the wall more strongly than the single-ply patch. The single-ply patch must be thicker to be stronger, thereby displaying a conspicuous terrace along the boundary between the patch and the surrounding wall surface. By contrast, the double-ply patch makes the lower sheet smaller in area and can consequently reduce the height of the terrace formed along the boundary between the upper sheet and the surrounding wall surface (the thickness of the lower sheet is not substantially added). This makes the boundary less prominent. The irregularly corrugated edge of the upper sheet makes the boundary between this sheet and the surrounding wall surface even less prominent. The combination of the separate sheets makes it possible to form the lower sheet of sufficiently strong material and the upper sheet of suitable material. As a result, it is possible to repair the wall surface with sufficient strength in sufficiently desirable condition.

[0017] The application of the erasing agent eliminates the difference in level along the boundary to make the repaired area inconspicuous.

[0019] This makes it possible to inconspicuously repair a wall having a rough surface texture with a matted or embossed pattern recently in fashion. In this case, the boundary between the upper sheet and the surrounding wall surface can be repaired with a boundary-erasing agent that can foam to provide a similarly rough texture having a matted or embossed pattern. This makes it possible to repair the wall almost inconspicuously.

[0021] This makes it possible to repair a linear or small flaw in the wall almost inconspicuously with the upper sheet and the boundary erasing agent by providing a rough texture having a matted or embossed pattern, which is similar to the surface texture of the wall.

Problems solved by technology

However, it is not necessarily easy to handle the materials for the wall repair in the case of the mending putty, for instance, because it requires skill to produce a new plane flush with the wall including the unevenly dented portions; and besides, it would be a lot of trouble to knead the putty or to use a spatula to level the wall face.

Similarly in the conventional method of wall repair resorting to the mending sheets (patches), a satisfactory result may not be obtained all the time in reproducing and maintaining the original flat surface because the sheets can eventually become depressed in themselves due to the insufficiency of the rigidity of the single-plied thin sheets which are commonly used to cover up the holes or dents in a wall.
