Abstract
Abstract A method and device for repairing fasteners attached to plaster board, where the plaster board has become loose around the fasteners. The method is particularly useful to repair loosened threaded fasteners affixed to plaster board which have worked loose due to the brittleness and chalkiness of the plaster board. The device consists of a syringe or like implement to which is attached a specialized needle. A bonding agent is pushed by the syringe through openings in the needle and into the plaster board after the needle is inserted into the plaster board in the immediate proximity of the fasteners.
