A syringe-dispensing system includes a housing containing at least one sealed bag of a fluid reactive compound and a nozzle in fluid communication with the housing for providing an outlet from the housing for the compound. A shaft disposed within the housing and attached to a handle for moving the shaft longitudinally within the housing is provided, along with apparatus for piercing the bag upon movement of the shaft in one direction. A piston enables forcing of the compound out of the housing through the nozzle upon movement of the shaft in an opposite direction.
