Deeper Damage: Fillers, Putty, and Careful Sanding
Use water-based wood filler for easy cleanup and quick shaping, or solvent-based filler for tougher, closed-grain results. Mix colors to match darker heartwood or lighter sapwood, and consider warm versus cool undertones. A near-perfect color match makes later staining optional, especially on stained pieces.
Deeper Damage: Fillers, Putty, and Careful Sanding
After filling, sand with a block, never fingertips, to keep surfaces flat. Progress through grits, typically 180 to 220, feathering outward to blend edges. Stay strictly with the grain, and stop early to avoid creating a dish. Good lighting from the side reveals flaws before finishing.
