Guys looking for a little help here and haven't been able to find a direct answer. I'm building a gas forge with a propane tank shell with two 1" layers of kaowool. My questions come to the kaowool. My order is going to be the following:
kaowooI, rigidizer, kastolite 30, itc 100, and some firebrick on the bottom.
My question is as I'm doing two 1" layers, do I need to apply all three solutions rigidizer, kastolite 30, and itc 100 to both layers of kaowool. Or should I just use Rigidizer on the first layer and the other solutions only on the second layer. Secondly should I cure the rigidizer between each layer, or put both layers in and cure both together?
I apologize if this has been asked before, but after going through forum after forum I have been unable to find a direct answer. Any tips on type of rigidizer are also appreciated.
