A resilient abrasive article includes a resilient elongatable substrate, abrasive particles adhesively bonded to the substrate with a flexible make coat, and a hard size coat applied over the abrasive particles and flexible make coat. The size coat provides an anti-loading layer which is applied thinly enough to prevent the size coat from cracking and tearing the substrate during use.

A resilient flexible sanding sponge including a foam backing layer having a layer of abrasive particles distributed along one of its major surfaces that are adhered together and to the backing layer by a layer of flexible adhesive material. That backing layer has about the same flexibility and conformability as the backing layers on prior art sanding sponges, while having a significantly higher tear strength than prior art sanding sponges. That high tear strength backing layer can either be (1) a layer of felted urethane foam; or (2) a layer of foam that encompasses a reinforcing material. When the backing layer is of felted urethane foam the layer of flexible adhesive material can have a major structurally sound portion below the surface along which the layer of abrasive particles is positioned and a minor portion adhering the abrasive particles along that surface to leave large portions of the abrasive particles projecting above the layer of adhesive material where they can effectively abrade a surface over which the sanding sponge is rubbed.

The invention provides a flexible abrasive product comprising a flexible sheet-like substrate comprising a multiplicity of separated resilient bodies connected to each other in a generally planar array in a pattern which provides open spaces between adjacent connected bodies, each body having a first surface and an opposite second surface; and abrasive particles to cause at least the first surface to be an abrasive surface. A method of making the abrasive is provided by providing the substrate and providing abrasive particles to at least the first surface to provide an abrasive surface.
