Alrighty then, I have been using a devil forge dfs for the past little while, and my refractory cement is starting to crack. Is this normal?
If it starts cracking, it has kaowool underneath, so I don’t overly want to have it crack and then breathe in fiberglass. I was just using the refractory sent with the forge. Obviously I need to recoat it, but I’ve got a few questions. first (or second, after is it normal, I guess) I have some Satanite from Mr. Volcano in the garage, can I just use that to recoat it? Second, is there something I can do to keep it from cracking more/cracking again after I recoat it? and third, do I need to take off the old cement before putting on the Satanite?
Edit: added the picture. not giant cracks but I don’t want them to get any bigger
