Abstract: A micro injection assembly for the repair of floors that includes an adapter body operably configured to couple with a tube having adhesive and defining an internal channel, a hub selectively removably coupled to the adapter body and having a rigid needle member coupled thereto and recessed within the hub, wherein the rigid needle member projects outwardly from the second end of the hub in a linear orientation, has a blunt distal end, and defines a needle channel spanning the length of the needle member. The assembly also includes a cap selectively removably couplable to the adapter body in a watertight configuration and with the cap disposable in an overlapping configuration with the adapter body. The assembly is operable to effectuate emission of an adhesive material from a tube through the adapter body, hub, and needle member to spaces between a flooring material and subfloor.

Abstract: The invention is a method and apparatus for repairing a portion of a floor where a flooring material has become separated from a subfloor, the method includes the steps of: determining a separated area of the flooring material; drilling a first injector hole at the separated area to a void between the flooring material and the subfloor; injecting a liquid adhesive into the first injector hole via an injection nozzle to deliver the liquid adhesive into the void of the separated area; and allowing the liquid adhesive to set. The apparatus is the injection nozzle including a body having a first end, a second end and a passageway extending between the first end and the second end, the first end being configured to receive the liquid adhesive into the passageway, and the second end comprises a pre-formed hole configured to deliver the liquid adhesive from the passageway to the void.
