A lightweight tool for applying compound to drywall and like surfaces is achieved by using closed-cell foam to form an application layer secured to a stiff plate. A handle secures to the stiff plate to facilitate use. An application layer made of closed cell foam of substantially uniform thickness nonetheless provides a lower surface having contoured perimeter portions by conforming to a plate having upwardly sloping perimeter regions. In an alternative embodiment, perimeter portions of an upper surface of an application layer are formed to be downward sloping. The upper surface of the application layer may be secured to the lower surface of a plate. The downward sloping portions may be deformed upwardly to be flush with the plate, creating corresponding upwardly sloping portions on the lower surface of the application layer. In yet another embodiment, the application layer is formed or machined to have an upwardly sloping perimeter portion.

What is claimed is: 1. An apparatus for applying drywall compound to a surface, the apparatus comprising: a plate comprising an upper surface and a bottom surface, the bottom surface of the plate having a flat central portion and an upwardly sloped perimeter, the upwardly sloped perimeter having a slope of less than 45 degrees relative to the flat central portion as measured progressing outward from the flat central portion of the bottom surface toward an outer edge of the upwardly sloped perimeter; an application layer having a substantially uniform thickness and a rectangular cross-sectional shape previous to bonding; the application layer bonded to the upper plate to conform to the upwardly sloping perimeter to provide an application layer with a flat central region and a sloped perimeter; and a handle secured to the upper surface of the plate. 2. The apparatus of claim 1, wherein the sloped perimeter has an area that is equal to a substantial percentage of the area of the flat central region. 3. The apparatus of claim 1, wherein the application layer is substantially more compressible than the plate. 4. The apparatus of claim 1, wherein the application layer comprises closed-cell foam. 5. The apparatus of claim 1, wherein the upwardly sloping perimeter portion is formed as a bevel. 6. The apparatus of claim 1, wherein the sloped perimeter has a slope relative to the flat central region in the range of between about 10 and about 20 degrees as measured progressing outward from the flat central region toward an outer edge of the sloped perimeter. 7. The apparatus of claim 1, wherein the application layer extends beyond the upwardly sloped perimeter.
