Appl. No.:

16/922846

Inventors:

Stephen Koehl - Anaheim CA, US

International Classification:

E04G 23/02

Abstract:

A wall repair system includes a balloon that can be inflated within a wall space behind a hole in the wall. The balloon itself, or a backer board attached to the balloon, can provide a surface for placement or build-up of wall repair compound so that the repaired wall has substantially the same thickness of the original wall and so that no tape or patch needs to be placed on top of the wall along any location surrounding the hole. The backer board can have one or more threaded holes therethrough where a threaded rod can be inserted into the threaded holes to contact a wall surface opposite the hole, causing the backer board to stay in place against the back side of the wall having the hole therein, thus blocking all or a part of the hole.
