Kiln cement for chipped brick
Posted: Fri Mar 07, 2014 5:27 pm
I bought a used kiln and it had a fair amount of chips along the edge of the lid and the body from the previous owner propping it open. I decided to skim a thin layer of furnace cement over the bricks to keep them from flaking. The layer started lifting and peeling as it dried, taking brick chunks with it. I peeled it off and used Paragon cement. Same thing happened. Any thoughts on why this is happening? I had done this once on another kiln without any problems.
