For conditioning a mold, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • For hot molds and composites, pay particular attention to mold material, coat count, cure between coats and mold temperature.
  • At 60°C. It is 10 minutes at 93°C and 4 minutes at 150°C.

How to check readiness
