ABSTRACT:
An apparatus and method for applying mortar, grout, bonding materials and caulk ("sealing material") into or between building components or materials includes a handheld power tool having or adapted to mount, a hopper receiving a supply of sealing material, an auger associated with the hopper selectively to convey the sealing material, and a nozzle adjacent the end of the auger to direct the sealing material to the point of application. The auger may have temporary auger extension(s) releasably and rotatably coupled thereto for conveying sealing material into voids, cracks or holes ("holes") in the building components or materials, with the temporary auger extension(s) being uncoupled and left in the filled holes as a central anchor or reinforcing member. When used with caulk, the apparatus is preferably adapted to have a disposable caulk container coupled to the assembly to replace the hopper and a removable and disposable plastic auger assembly to replace the steel auger.
