This is a water-based refractory coating sold as a 5 lb bag of dry mix, meant to be applied over ceramic fiber blanket, refractory brick or crucibles. It reflects radiant heat back into a furnace, kiln or gas forge, which speeds heat-up and cuts fuel loss. The mix resists up to 3000°F and is thinned with clean water for brushing or spraying at a 1.5 to 2 mm layer. It suits hobby and small-shop forge and kiln builders rigidizing fiber linings; it is a coating, not a structural castable, so it does not replace refractory mortar or brick for load-bearing joints.

This refractory cement is a water-based coating used as a cover for ceramic fiber insulation and other refractory products. It reflects radiant heat back into a furnace, kiln, or forge so it reaches high temperatures quickly. This prevents heat loss and saves fuel or power.
The coating resists temperatures up to 3000°F (1648°C). It works as a fireproof coating in a gas forge and on ceramic fiber linings, protecting them from direct flames, furnace heat, and fumes. This prolongs the life of refractories.
It adheres to refractory bricks, ceramic fiber insulation, and graphite or carbon crucibles. It has excellent dry strength and adds strength to a ceramic fiber blanket. To apply by spraying or brushing, mix in 22-30% clean tap water by mass. The coating layer should be 1.5 to 2 mm thick.
