Does water damage polymer clay?

Polymer clay is a versatile and popular material used for crafting various artistic projects. However, questions about its susceptibility to water damage often arise. In this article, we’ll delve into the effects of water exposure on polymer clay and provide insights into how to protect and care for your polymer clay creations.

1. Water Absorption

Polymer Clay Composition:

Polymer clay is not highly porous:

Polymer clay is composed of synthetic polymers that are not highly porous like natural clays. This means that polymer clay is less likely to absorb water or moisture compared to traditional ceramics or earthen clays.

2. Immediate Water Exposure

Effects of Water:

Short-term water exposure may not cause significant damage:

Exposing polymer clay to water for a short period, such as accidental splashes or wearing polymer clay jewelry in the rain, is unlikely to cause immediate or severe damage. However, prolonged exposure to water or excessive moisture can lead to changes in texture or appearance.

3. Long-term Water Exposure

Texture Changes:

Extended water exposure can affect the clay’s texture:

Over time, continuous water exposure can lead to polymer clay becoming softer or more pliable. This can result in changes to the texture and rigidity of the clay, potentially affecting the shape and durability of your creations.

4. Protection and Care

Sealants and Finishes:

Applying sealants can provide water resistance:

To protect your polymer clay creations from water damage, consider applying a clear sealant or varnish. Sealants can create a barrier that helps repel water and moisture, reducing the likelihood of texture changes or degradation.

5. Storing and Drying

Proper Storage:

Store polymer clay creations away from water sources:

When not in use, store your polymer clay items in a dry and safe place away from water sources. Avoid exposing them to excessive humidity or damp environments, as this can contribute to long-term texture changes.


If polymer clay gets wet, dry it thoroughly:

If your polymer clay creations do come into contact with water, gently pat them dry with a clean cloth and allow them to air dry completely before storing them. Avoid using excessive heat or rapid drying methods.


While polymer clay is not highly porous and short-term water exposure may not cause immediate damage, long-term water exposure can lead to changes in texture and appearance. To protect your polymer clay creations, consider applying sealants, practicing proper storage, and ensuring thorough drying if they come into contact with water. By following these precautions, you can enjoy the beauty and durability of your polymer clay projects for years to come.
