A self-adhesive wall board joint tape has a paper base layer with a mud or plaster receptive surface, the other surface has a pressure sensitive adhesive. A transfer liner is applied with a release surface against the adhesive surface of the paper base layer, and is coated on the opposite side with a low-tack releasable adhesive. When wound into rolls the transfer liner low-tack adhesive engages the untreated surface of an underlying base layer. The pull strength of the low-tack adhesive is selected to be greater than the pull strength of the high-tack adhesive on the release surface of the transfer liner. When unwound from the roll the transfer liner is adhered to the non-adhesive paper base layer, and the adhesive high-tack surface of the paper base layer is presented for immediate adhesion, without the need to remove a backing.

[ We claim:] [1.] A tape assembly for bridging the joint between two adjacent wall board panels, the assembly comprising:a) a paper base layer having an outer surface;b) a high tack adhesive disposed on an inner surface of the paper base layer;c) a transfer liner having a release surface which is engaged with the high tack adhesive on the base layer;d) a low tack adhesive disposed on a surface of the transfer liner opposite the release surface, wherein the base layer and the transfer liner are wound into a roll such that the low tack adhesive on the transfer liner engages the outer surface of an underlying portion of the paper base layer, and wherein the force required to separate the high tack adhesive on the inner surface of the base layer from the transfer liner is less than the force required to separate the low tack adhesive on the release liner from the outer surface of the base layer, the low tack adhesive being such that when the release liner is removed from the base layer, little residue is left on the base layer, and the receptiveness of the paper base layer to drywall mud or plaster is not substantially impaired.
