The Sharp Foam Pad with a soft backing foam allows it to adapt perfectly to all profiled work pieces, and it reduces sanding through and guarantees an even and uniform sanding pattern. There is no risk of sanding through thanks to ‘pressure-equalizing’ foam. It can be crumpled up and stretched without creasing. There is consistent performance throughout the life of the product and ensures a high quality and even finish. The abrasive grain does not cut into the substrate as deeply and breaks off less, resulting in a more even surface finish. The Sharp Foam Pad is very handy, as both sides can be used wet or dry and can be rinsed with water.
