I have been using HeatStop 50 refractory mortar for my dome. I used two bags, both brown. The third bag I just ordered in is white, and states HeatStop 50 refractory cement (rather than refactory mortar). The dealer told me it's the same, that heatstop 50 is all one product, just an older bag. Is this the case?
No announcement yet.
HELP - Heat Stop 50 cement?
