Abstract: A method using a mixer for disbursing an additive in a tube of compound. The mixer includes a rigid cylinder and a plunger assembly. The cylinder is configured for receiving an opened tube of compound, to which additive has been introduced. The plunger assembly includes a shaft, on which a cap is slidably and rotatably mounted. A mixer blade is mounted on a first end of the shaft and a second end of the shaft is provided with a handle. The cap is provided with a pair of cutouts designed for receiving a pair of studs mounted on the outside surface of the cylinder, such that the cap may be fitted on the cylinder and turned to engage the studs with the cutouts and connect the cap and the cylinder. The handle may be rotated and reciprocated to move the mixer blade through the contents of the tube for mixing.
