What sanding grit is used between coats of Bona Traffic HD?

P150 or finer

Bona specifies P150 or finer for intercoat sanding on Bona Traffic HD. 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.
