What sanding grit is used between coats of Bona Classic UX?

120 grit final sand, then finest that achieves desired result

Bona specifies 120 grit final sand, then finest that achieves desired result for intercoat sanding on Bona Classic UX. Intercoat sanding or screening removes dust nibs, flattens applicator lines, and provides a mechanical key for the next coat. Too-coarse grit leaves scratch showing through; too-fine or skipped sanding weakens intercoat adhesion.
