ABSTRACT:
A labor saving taping system for use during the installation of gypsum wallboard, whereby the seam between a pair of adjacent drywall panels can be easily and reliably taped with paper drywall tape that has been pre-coated with wet adhesive mud. This system comprises the detachable interconnection of a frame and a mud reservoir. The drywall tape is fed from a supply roll and threaded along the frame for total emersion in the reservoir so as to receive a coating of mud on both sides thereof. The system also includes a taping tool comprising a hollow housing and a shaft around which the mud-coated drywall tape can be wound for storage and later use.
