The Good - No frost heave this winter. The dome is still strong and perfectly together. No major cracks and its ready to be fired.
The Bad - My entire stucco job on the outside block walls totally came off due to moisture. Take a look:
I chipped the perlcrete back to the dome to reveal the hearth slab and chipped off the remaining stucco on the walls. I am thinking the horizontal surface caught the water and funneled it down the perlcrete layer, then went between the stucco.
I am thinking of building up the flat areas and sloping away from the hearth perlcrete based.
Looking for any insight into sealing the block walls. What can I put on these walls so I know it won't come off?
