What sanding grit is used between coats of Bona DriFast Stain?
P100 for hardwoods or P120 for softwoods final sand
Bona specifies P100 for hardwoods or P120 for softwoods final sand for intercoat sanding on Bona DriFast Stain. 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.
