Abstract: A wallboard patching element is collapsible to fit through a hole in the wallboard. Using a handle, the element is moved through the hole and inside the wall adjacent to the hole. Once inside the wall, the element is released into a fully deployed condition with part of the element larger than the hole. The patching element has adhesive on portions that contact the wall, and is moved into contact with the wall. Once the patching element is fixed to the wall, the handle is removed, and tape or other patching material is used to fill in any gaps remaining between the patching element and the wall.
