How do I test a substrate to make sure it is suitable for encaustic painting?

If you want to make sure that the method you are using will stand the test of time, use the freezer test. The freezer test is a way to check if a substrate or underpainting method is suitable for encaustic art.

  1. Start with a sample project
  2. Add layers of encaustic medium on top of the substrate you want to test
  3. Properly fuse each layer of encaustic medium
  4. Allow it to cool completely.
  5. Place it in the freezer and leave it overnight
  6. Remove it from the freezer and allow it to get back to room temperature
  7. Drop it on a concrete floor with force, multiple times
  8. You may wish to repeat the freeze thaw cycle multiple times as well
  9. Inspect the painting —dented corners aside, if the encaustic has chipped away and separated from the underpainting or substrate then it isn’t compatible—if it held, then it is acceptable.
