What sanding grit is used between coats of Bona Intense?
120 grit final sand
Bona specifies 120 grit final sand for intercoat sanding on Bona Intense. 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.
