What do you seal polymer clay with?

Sealing polymer clay is a common practice to enhance its appearance, protect the surface, and provide a glossy or matte finish. There are several sealers and finishes available that are compatible with polymer clay.

Polymer Clay Varnish

Polymer clay varnish is specifically formulated for use with polymer clay. It provides a protective layer that can be glossy, matte, or satin. Varnishes are easy to apply and offer long-lasting results.

Acrylic Sealers

Acrylic sealers, such as clear acrylic spray, can also be used to seal polymer clay. They create a durable protective layer and are available in various finishes, including matte, satin, and glossy.

Wax or Paste Finishes

Wax or paste finishes are applied by hand and can create a unique texture and sheen on polymer clay. They are often used for antiquing or adding a weathered look to clay creations.

Application Tips

When sealing polymer clay:

  • Ensure your clay creation is clean and free from dust or debris before applying the sealer.
  • Apply the sealer in thin, even coats, allowing each coat to dry before applying the next.
  • Follow the manufacturer’s instructions for the recommended drying time and number of coats.


Sealing polymer clay with a compatible varnish, acrylic sealer, or wax finish can enhance its appearance and provide protection. Choose a sealer that matches your desired finish and follow proper application techniques for the best results.
