TheDudeXxxx Posted February 17, 2023 Share Posted February 17, 2023 So I have a Hells Forge Deluxe double burner forge. Initially it came shipped with the Kaowool installed but I had to mix and apply my own refractory ( supplied by them). I followed the instructions from the company as to applying to a T. The forge after the initial burn process immediately had small cracks which grew over time as well as all the chipping. Fast forward a couple years I’ve decided to rip everything out and start over. I have installed the Kaowool and have applied and cured the rigidizer. I also do a lot of wood turning so I have a fairly good size kiln that I use for drying bowl blanks. After applying the rigidizer I put the entire forge into the kiln overnight at 90 degrees and it came out great. My question is, if I apply thin coats of refractory 1/16”-1/8” and put it back in the kiln would it cure it too fast and cause the same issues I had before with cracking? I can regulate the temperature all the way up to 150 possibly more if I add another temp light but if I’m remembering correctly optimal cure temp is 70-90 degrees. Any input would be appreciated.

M3F Posted February 17, 2023 Share Posted February 17, 2023 I would think you would be fine. You could always save some refractory for when a crack inevitably shows up then just patch it. That's what I do anyway. Quote Link to comment Share on other sites More sharing options...
Goods Posted February 17, 2023 Share Posted February 17, 2023 Be careful. What type of refractory are you using? I believe most refractory requires moisture to cure, it won’t set dry. I also understand the rigidizer should be heat fired to a dull red, but I’m not sure if it should be dry first or not. My info may not be correct, but make sure what the material you’re using requires before you proceed. Keep it fun, David Quote Link to comment Share on other sites More sharing options...
TheDudeXxxx Posted February 20, 2023 Author Share Posted February 20, 2023 So follow up... The Satanite came out great. I let each coat cure in the kiln overnight around 85-90 degrees. There were a couple super small hairline cracks but nothing to call home about. I plan on lining it with ITC100 today so that should take care of the small cracks.I appreciate the input. Hopefully i'm back in the fire tomorrow evening after work. First time using this ITC100 so fingers crossed. Quote Link to comment Share on other sites More sharing options...
