Abstract
A finishing tool is used to smooth tape joints of interior walls and ceilings constructed of plasterboard or drywall. The tool includes a handle, a resilient polyester foam pad, and a wettable abrasive surface of short, stiff coarse nylon fibers bonded to the resilient foam pad so that they are oriented perpendicular to the surface of the foam pad. In use, the abrasive surface is wetted, and then is moved over the surface of the tape joint to moisten the joint cement. The tool is then moved in a scrubbing-type movement to work the joint cement to a creamy consistency. The surface of the joint cement is then smoothed by stroking the tool along the length of the joint.
Claims4
A method of smoothing wallboard joint compound on wallboard tape joint, the method comprising:
- applying water to the joint to moisten the wallboard joint compound;
- scrubbing the joint with a smoothing tool having resilient foam pad with a wettable abrasive surface bonded to one major surface to work the joint compound to a creamy consistency, wherein the wettable abrasive surface of the smoothing tool comprises a plurality of coarse, short, stiff synthetic polymer fibers oriented generally perpendicularly to the major surface of the pad and bonded to the major surface by an adhesive layer;
- and
- smoothing the joint by stroking the creamy consistency joint compound with the smoothing tool.
