Abstract:

A drywall tape comprises a narrow paper tape of uniform width and non-uniform thickness including a central portion of greater thickness and side portions of lesser thickness. The tape has a width to be disposed in a depression formed at a drywall joint by sloping outer surface portions of drywall sheets, respectively, forming the joint, such that a planar outer surface of the tape is substantially flush with non-sloping outer surface portions of the drywall sheets, respectively. An adhesive drywall tape includes a narrow paper tape having a layer of yucca adhesive pre-applied thereto. A drywall tape applicator includes a housing for receiving a roll of drywall tape as well as fluid for imparting adhesiveness to the drywall tape as it is dispensed from the housing for application to a drywall joint. A method of finishing a drywall joint includes securing a length of drywall tape over a drywall joint with a yucca adhesive such that the drywall tape extends the entire length of the joint, allowing the yucca adhesive to dry and applying a layer of joint compound over the drywall tape to blend the tape into non-sloping outer surface portions of the drywall sheets forming the joint.
