A method and sanding block formed by the method are included.

Claims (9)

1. A foamed rigid bottom sanding block, which includes:

a sanding block formed of polyfoam material having a bottom portion with an integrally formed rigid member made of a material and thickness to lend weight as well as rigidity to said bottom portion, said rigid member nearly spanning a length and a width of said bottom portion and which encased within said polyfoam material, and an upper portion of said sanding block having a handle which protrudes from said bottom portion and is made of said polyfoam material.

2. The foamed rigid bottom sanding block of claim 1 , wherein said rigid member is uniformly spaced from a bottom sanding surface of said sanding block.

3. The foamed rigid bottom sanding block of claim 2 , wherein said rigid member is spaced up to about 0.25 inch from said bottom sanding surface to provide sufficient coverage and prevent delamination.

4. The foamed rigid bottom sanding block of claim 1 , which includes a hook and loop member integrally connected to said bottom sanding surface by said polyfoam material.

5. The foamed rigid bottom sanding block of claim 1 , wherein said polyfoam material between said rigid member and a bottom sanding surface of said sanding block is more dense than said polyfoam material in said handle.

6. The foamed rigid bottom sanding block of claim 1 , wherein said handle is a shape symmetrically oriented along a longitudinal axis which generally aligns with a central axis of the block having a back end larger than a front end such that a downward slope exists from the back end to the front end.

7. The foamed rigid bottom sanding block of claim 1 , wherein said rigid member is made of one of plastic, metal and wood.
