ABSTRACT:
A plasterboard repair kit for use in patching a hole in a plaster wall includes a substantially cube-shaped inflatable member comprised of a flexible but substantially inelastic plastic. The front wall of the inflatable member includes a valved opening therein through which the device can be inflated and an interior retainer extends between the front and rear walls to prevent them from bulging after inflation. In its deflated form, the device is inserted into the cavity behind a hole in a plaster or plasterboard wall and is then inflated utilizing a carbon dioxide cartridge in a holder having a nozzle inserted into the opening. After inflation, the inflated member acts as a seal behind the hole so that the hole can then be filled with plaster or other patch material.
