Abstract
A joint tape for use in building construction utilizing dry wall panels which includes a tape body of water absorbent paper, sized and shaped for smooth joints between dry wall building panels, and a layer of water-activable polyvinyl acetate-based adhesive on one side of the tape for wetting and then adhering the tape to the surface of adjoining dry wall sheets covering the joint therebetween.

A joint tape for covering and sealing the joints between adjacent wall board panels comprising:
- a thin, parallel sided, elongated strip of water absorbing paper tape;
- and
- a dried, water moistenable, polyvinyl acetate-based adhesive layer applied to completely cover the surface area of one side of said tape whereby the adhesive layer may be moistened with water to activate the adhesive layer so that the tape may be applied directly to the wall board joint to seal adjacent wall board panels together, said joint tape being further characterized in that after being moistened and applied to said panels and dried, the tape cannot be removed by remoistening the adhesive layer.
