Pressure sensitive adhesive repair product

Abstract

A repair device which includes an intermittent coating of PSA on a first side of a sheet of release paper. The cured PSA may be easily transferred to a surface by pressing the release paper against the surface thereby effectively transferring the intermittent coating of PSA to the surface. The improved repair device is useful for repairing delaminated or detached wallpaper, holding wall patch repair devices in place during the application of spackling or repair compound and holding door hinges in place during the installation thereof.

Description

TECHNICAL FIELD [0001] An improved system for applying pressure sensitive adhesive to a surface or substrate as disclosed. More specifically, pressure sensitive adhesive is applied intermittently, such as in a swirl pattern, dot pattern, checkerboard pattern, etc. is deposited on a first side of a release paper or release sheet. The pressure sensitive adhesive is then allowed to cure. The adhesive is applied to a surface such as the back side of a detached piece of wallpaper or the surface of an item such as a piece of hardware that needs to be installed by simply pressing the release paper against the surface with the cured pressure sensitive adhesive sandwiched therebetween which will then result in a pressure sensitive adhesive being transferred from the release paper to the back side of the detached wallpaper or the hardware item. A cover sheet of release paper may also be used and applied over the cured pressure sensitive adhesive and first side of the primary release paper or ...

Benefits of technology

[0011] Similarly, to temporarily or permanently hang a mechanical device, repair mesh or other device to a vertical surface, the first side of the release paper may be pressed against the back side of the device that will engage the vertical surface and pressure applied to the second opposing side of the release paper results in transferal of the PSA to the device. Then, the repair patch, door hinge or other device is pressed against the vertical wall surface with PSA sandwiched therebetween to temporarily or permanently attach the repair patch, door hinge or other device to the vertical wall surface. One advantage of the disclosed repair device is that the PSA will not plug or block the holes of the door hinge, repair mesh or other fixture. Further, use of the disclosed repair device can render a fixture such as a door hinge, nail guard or other fixture “self-adhering” thereby eliminating the need for liquid adhesive and its disadvantages as disclosed above.

Problems solved by technology

Pressure may be applied to the second opposing side of the release sheet which results in a transferal of the pressure sensitive adhesive to the back side of the wallpaper.
