Abstract: A backing device useful in repairing a hole. In some embodiments, the hole is in a wall, for example a relatively large hole in a wall (e.g., vertical wall, ceiling, etc.) of, for example, a home or building structure. The backing device includes a collapsible backing member and adhesive strips. The backing member defines a front face opposite a rear face, and includes first and second panels connected at a hinge segment. The adhesive strips are disposed on the front face. The backing member is foldable from a flat state to a collapsed state for insertion through the wall hole. Once deployed “behind” the wall, the backing member is transitioned to the flat state, and the adhesive strips utilized to secure the backing device to a back surface of the wall. In some embodiments, the backing device, while in the flat state, is relatively rigid in one direction and collapsible in the opposite direction.
