There was a similar post a couple days ago where the poster had issues with his topcoat never properly hardening. IIR the consensus was he didn’t let the countertop dry properly before he put the topcoat on.

Had a similar problem. Wall had a light orange peel texture and after spackeling it looked horrible with all the smooth spots sticking out like a sore thumb. Had to skim it to fix it. TLDR just go straight to skimming.
