There is a lot more checking than I realized, and I'm afraid filling these gaps by just pouring in epoxy will be difficult. I want to keep the live edge and avoid making a complete deep pour epoxy mold. Some of these gaps go all the way through The 2-in slab. Any tips for me?
I bet it would squeeze out around the edges. Since there's air in the voids/checks, the resin won't have a way in. You'd be left with a thin layer covering the voids but not filling them, so as soon as you sand it flat the voids reopen
