What sanding grit is used between coats of Bona Traffic HD Anti-Slip?
150 grit or finer
Bona specifies 150 grit or finer for intercoat sanding on Bona Traffic HD Anti-Slip. 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.
