The present invention is directed toward flexible embossed supportive backings for coated abrasives, which are used with "sanding" tools. The supportive backing is made from a flexible elastomeric material embossed on one side with a predetermined pattern. The embossment pattern includes an uninterrupted narrow border along the edges that lay perpendicular to the primary of travel during use, a plurality of narrow grooves within the border which disrupt the surface area of the elastomeric material, and lines of severance that partially separate the edges of the material from its main body. The surface acts as the supportive backing for a coated abrasive as it is worked over a roughened surface. The grooves created by the embossment pattern allow the coated abrasive to deform as it encounters high points on a roughened surface, which allows the abrasive to surround the contours of the roughened surface and greatly increases the efficiency of the coated abrasive. The grooves created by the embossment minimizes the work dust trapped between the coated abrasive and the supportive surface, which minimizes high points and uneven results.
