Abstract
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.
