What sanding grit is used between coats of Bona Mega ONE?
150 grit or finer
Bona specifies 150 grit or finer for intercoat sanding on Bona Mega ONE. 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.
