    release agent. Sulfur free grease can be used as a release agent.
  2. Use a Hobart type mixer.
  3. Check that equipment is clean and in proper working condition.



  1. Only mix as much material as you can place immediately.
  2. Determine the correct wet to dry ratio. The ratio is by weight.
  3. Mix dry material and liquid activator together for between 2 and 4 minutes depending on the
    mixer. The material is mixed properly when it folds upon itself and looks homogeneous.
