Many designs in polymer clay look better (more professional and refined) after sanding and buffing.

The silicon carbide sandpaper included in each Poly Clay Play Sandpaper Kit is specially treated waterproof paper which can be used wet or dry for quality finishing.  Please read the information below for the recommended way to sand polymer clay.

Sanding Polymer Clay - Tips and Information

Sandpaper comes in different grits. The lower the grit number, the coarser the paper; the higher the number, the finer the grit.

When sanding polymer clay, always start with the lower grits and work your way up, step by step, to the higher grits. It's best to not skip a grit (i.e. don't go from 400 to 1000, but go from 400 to 600 to 800, and so on). Skipping grits can leave gouges on the clay. It is also advisable to stick with one brand of sandpaper. Different brands may not have interchangeable grits. For instance, the 600-grit paper from one manufacturer may be the same as the 400- or 800-grit paper from another source. You could unintentionally be skipping grits of even going backwards on the grit scale.

Wet sanding is recommended to prolong the life of sand paper and to avoid inhaling the dust. If you prefer to dry sand, be sure to wear a protective mask.

Some people say that soaking your sandpaper for five minutes before beginning to sand will prolong the life of the paper. You may sand under running (or trickling) water or in a shallow bowl of water. It's a good idea to add a drop or two of liquid soap to the sanding water.  The water cuts down on polymer dust and helps unclog the sandpaper. The dish soap slows down clogging the paper with grit. Once the sandpaper gets clogged, dip it in the water and use a toothbrush to remove the grit. You’ll know when it’s time to replace the sandpaper with new, as it will lose its effectiveness.

It is not necessary that you submerge the clay and paper the entire time, but you'll want to dip them down into the water frequently to prevent the paper from becoming clogged with residue. Periodically change your sanding water.

    Perfect range of grits for hand sanding

    Posted by Rebecca on May 26th 2022

    This is a very affordable, great range of grits, package of sandpaper. There are 2 pieces of each grit graduating from 600-3000 and 4 pieces of the 400 grit. This sandpaper is very good for wet sanding and holds up well. To prevent the paper from curling up after wet sanding I place a tile on top of it while it dries and it will remain flat once dry.
