The present invention relates to a fluid-activated drywall tape applicator. The applicator includes a roll of fluid-activated drywall tape, a container, a lid and at least two slits. In operation the roll of tape is affixed to the applicator and a lead end of the tape is fed through a first slit. Once in the first slit the tape enters the container where the container is filled with a fluid. The fluid saturates the tape and the tape leaves the container through the second slit. After leaving the container via the slit, the tape's adhesive properties are activated and a user may apply the tape to a working surface.
