Can you smooth polymer clay after baking?

If you’ve noticed imperfections or rough surfaces on your polymer clay creations after baking, you might wonder if it’s possible to smooth them out. While polymer clay cannot be reshaped or re-molded after baking, there are techniques you can use to improve the surface.

Sanding and Buffing

Sanding is a common method for smoothing polymer clay after baking. Use fine-grit sandpaper to gently sand the surface, gradually moving to higher grits for a smoother finish. After sanding, you can buff the clay with a soft cloth or polishing pad to achieve a glossy shine.

Liquid Clay or Varnish

Applying a thin layer of liquid polymer clay or a polymer clay-compatible varnish can help smooth out minor imperfections and create a more even surface. Make sure to follow the manufacturer’s instructions for application and curing.


While you cannot reshape or re-mold polymer clay after baking, you can use sanding, buffing, and other surface techniques to improve the appearance and smoothness of your creations. With patience and attention to detail, you can achieve a polished and refined finish.
