Abstract: A mud pan support device magnetically attachable to, and releasable from, a flat bottom panel of a mud pan to be carried in one hand while applying joint compound with a trowel or mud spreading tool held in the other hand. The device includes an elongated substantially flat support panel and a handle connected to and extending from a central area of one surface of the support panel. A substantially flat magnetized panel is connected to, and is at least partially coextensive with, another surface of the support panel and is sized to be at least partially coextensive with the bottom panel of the mud pan. The magnetized panel is of sufficient magnetically attractive strength to serve as an only means for secure magnetic engagement between the magnetized panel and the bottom panel when the mud pan is filled with mud or plaster.

Abstract: A device for abrading and finishing excess cured filler material from a bullnose outside cornerbead connected between immediately adjacent sheets of drywall. The device includes an elongated rigid body having a generally concave-shaped central longitudinal portion which replaceably receives a highly compressible elongated abrasive member which is substantially coextensive with, and arcuately formable to match against the bullnose cornerbead convex contours. A guide runner extends along either longitudinal side margin of the central longitudinal portion. These guide runners substantially match and glide along the outside angle between the adjacent drywall sheets when there is substantial compression in thickness of the abrasive member firmly engaged against the bullnose cornerbead.
