Abstract: A grout dispensing system that includes an injector having a number of user selectable dispensing nozzles that allow an individual to select a desired dispensing opening diameter for a particular job and which includes a piston/plunger for forcing grout out of the nozzle under pressure into the gap between tiles to ensure that a proper amount of grout is within the gap. The injector includes a hand grip assembly that is gripped by a user with one hand while simultaneously pushing the plunger/piston into the injector cylinder.
