What sanding grit is used between coats of Bona White?

150 grit or finer; every coat of White must be sanded

Bona specifies 150 grit or finer; every coat of White must be sanded for intercoat sanding on Bona White. 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.
