Saturday, yesterday and today we have spent many hours cutting the floor tiles, puzzling them together as best we could to fill in many gaps around the sides, and then today we mixed up the sand/high-temp-mortar barely-wet mix, and set them. It's been a bit of a nightmare - the floor pan is not level, it has ripples and bumps all over it, plus the seam where the two halves join is not flat. The floor tiles themselves are imperfect with respect to shape and to level-ness, and they chip easily. All in all, we did the best we could do, and I'm not sure it's good enough. Those of you that have been following this thread know what perfectionists we are, and this floor is nowhere near perfect, and it's driving me crazy. The biggest issue is where the outside deck meets the floor tiles just inside the doorway; we have a rise of about 3/16". I've attached photos to show all of this. I'm frustrated because the other FGM ovens we've seen do not seem to have this issue. My fear is that sooner or later someone will be less than careful and will hit that with the peel and it will start chipping... It's way to the front of the cooking area so one shouldn't hit it with the peel, but I'm sure it will happen at some point. Once the dome is on this will be MUCH harder to fix, and we are supposed to get the dome up Thursday so we have a small time crunch.
Question: can we sand it to chamfer that rise? We would use a power sander, a belt sander to do the rough work and then a random orbital sander with fine paper to finish it. We tried sanding a leftover piece of firebrick and it seemed to work fine - is there any reason not to do so? It did remove the slightly darker factory patina but so did cutting them and that will get rubbed with time anyway, right? The main floor is pretty smooth, the only real issue is the entrance.
