Super flat sander

DETAILED DESCRIPTION The present invention provides a more efficient alternative to conventional sanders and produces a finished interior wall that appears smooth and continuous while using less effort than conventional sanders.
One embodiment of the present invention is designed to coact with conventional sanders which are acceptable for use on nail holes, angles, and cornerbeads, but are not as effective as the present invention for use on wallboard joints themselves.
More specifically, the present invention provides an oversized sander for use primarily on the joints of dry wallboards.
The sander base has a sanding side on which an abrasive material is fastened for sanding and smoothing an interior wall, and an opposite fastening side on which support members, fastening means and locking means are located.
The sander is made of an extremely rigid material and has at least one support member fixed to the base for providing added rigidity to and preventing warping of the sander base.
The sanding area of the sander base is up to four times larger than a conventional sander.
The sanding side of the base preferably is covered with a thin layer of resilient material.
A fastening mechanism is provided on the fastening side of the base for securing a flexible sheet carrying an abrasive material to the base.
One embodiment of the invention also has a locking mechanism on the fastening side of the base for locking a conventional sander to the sander base.
This embodiment quickly engages and disengages with a conventional sander.
In use, the present invention provides a much more efficient tool for sanding wallboard joints, and produces a finished interior wall that appears much smoother and more continuous than a wall finished with a conventional sander.
The present invention covers the entire seam at once and automatically finds the highest area of the drywall seam.
The super flat sander produces superior results quicker and more easily than a conventional sander since the super flat sander has approximately four times the sanding area as a conventional sander
