Kast-O-Lite 30 LI G Castable

6 items left

Kast-O-Lite 30 LI G is rated to 3000°F  and has great insulating qualities similar to the Kast-O-Lite LI 30 PLUS. It contains more lime, so hardens quicker (5-10 minute work time) than Kastolite 30 LI PLUS (30 minute work time) making it easier to apply up the side of a forge as it does not slump like casting grade. It will have slightly less of a compression grade but in a forge, this is not an issue.

You can cast it or mix and apply it over your Kaowool to add an additional protective layer. (best to toughen up the wool first with our freeze-proof rigidizer to prevent its compression during application.

Sizes Available:

  • 1 Gallon (1/6 bag)
  • 2 Gallon (1/3 bag)
  • 55 lb Bag     


Kast-O-Lite 30 Li G can be coated with ITC 100 HT, once cured, to optimize forge efficiency, and with ITC-296A (ITC-296A and ITC 213 are in stock and launching online soon)  for improved flux resistance.
