I recoated my forge with a can of rutland refractory cement last night. When I purchased the forge the layer of cement was cracked and falling off. I mixed a small amount of water to make it smoother to apply. After I finished let it dry with a fan to help the dryness. It is humid here in south Texas but, continued in drying process. I proceeded to use my torch and gradually apply heat inside the forge. It started to bubble, anyway kept up the heat slowly. Will the bubbles effect the burners or should I scrape the ugly bubbling effect and apply the cement again?. This is new to me so, please gentlemen comment and advise needed. Thanks,............Rey
