I’m working on insulating my new gas forge properly. I’m a little overwhelmed with all the recommendations online for rigidizer and refractory cement. From my research I’m pretty sure I’m supposed to rigidize the kaowool and then line the inside of my forge with a refractory cement. As of now I’m planning to use the Hell’s Forge Hellcote 3000 refractory. Is this a good one? I’m also unsure which rigidizer to use. I found this one on Amazon but I want to hear what folks recommend before I buy: Link remeved
I’ve seen that it’s best to use 2 layers of 1” kaowool. Is just one layer okay? Only one layer came with the forge so I would prefer to not have to buy anymore, but I will if necessary.
Any advice is appreciated as this is my first time insulating a forge.
Thanks in advance
