3M Sanding Sponge

This soft-backed sanding sponge is designed for shaping and fine-tuning your rigidized Silkemat moulds. The flexible foam pad makes it easy to reach curves, edges, and other difficult areas, helping you achieve smooth, precise contours.

Measuring 115mm x 140mm, it features a microfine abrasive surface ideal for delicate adjustments.

Recommended by Barbara Cashman and used in the Silkemat MasterClass, this tool is specifically for use on Silkemat and not suitable for sanding glass.
