All data on thicknesses, processing time and curing time are only approximate values. A large number of parameters such as temperature, casting volume, substrates have a decisive influence. The values may therefore deviate considerably in practice.

What is important in processing?

  1. Determine the required resin/hardener quantity. The R&G resin calculator helps you to do this.
  2. Weigh components accurately and mix resin and hardener thoroughly (drill +mixing propeller); then repot into a clean container and mix again.
  3. Allow the batch to stand for 15 - 30 minutes to deaerate. Remove rising air bubbles, which lie as foam on the surface after casting, with a hot air gun or gas flame (fire hazard).
  4. Set up fans (cold air) above the casting (e.g. Rivertable); this has proven effective in preventing overheating.
