hey guys! oven build is going great so far.
my finish is going to be stucco. I am planning to close off part of the front w/ firebrick, ceramic blanket, lathe/stucco. I would like to do all the insulation/lathe at once, meaning I have to remove the foam beforehand(so I can close part of the front off.) my question is, how long for the high-temp mortar to cure before I can safely remove the foam? (and any tips on removing the foam?) thanks!
