A very small piece of firebrick has broken out, and I am hoping I won't lose any more of it. Is there a liquid cement that I could pour on and seal up the crack?
Repair cement should not be used to fill cracks in firebricks, because the repair cement tends to break out later from the crack. This is due to the difference in expansion between the cement and the firebricks.
