So today is Day 7 and I have begun to strip the styrofoam away from the front and back slabs. While both are very solid the flanged areas and thinner parts are a bit brittle in places (see the missing chunk in the front panel flange). Please see photos. Please tell me this can be somehow fixed and its not a loss! A bit nervous before unpacking the sides and tops. If the voids can be patched do I use the high temp mortar? What about the flange on the front inside? Slightly brittle at the edge. Patch it all with the high temp mortar?
One more question. I noticed quite a few of the stainless steel fibers are at surface level. Do I try to pull them out? I’m having bad visions of a steel fiber or two ending up in a pizza.
Thanks in advance for your help!
