Find sanding scratches before the finish finds them

A surface can feel smooth and still carry scratches that become obvious under finish. The final sanding check deserves its own few minutes, with good light and a deliberate sequence.

Start with the defect, not a favourite grit

Choose an abrasive coarse enough to remove the tool marks actually present, without unnecessarily deepening the scratch pattern. Then work towards finer grits, removing the previous scratches at each stage. Fine paper is a slow way to erase marks left by a much coarser abrasive.

The stopping point depends on the wood and the finishing system. Check the finish manufacturer's preparation instructions. “Higher grit” does not automatically mean a better stained result, and a schedule intended for one product may not suit another.

Use light that reveals the surface

Bring a lamp low across the face rather than shining it directly down. Rotate the work and inspect from more than one direction. Pay special attention to edges, the area beside joints and places where a sander changed direction.

Draw a very light pencil witness line on a test piece while establishing your routine. Its disappearance can help you track coverage, but it cannot prove that deeper scratches are gone. Inspect the wood itself before moving to the next grit.

Keep the abrasive and the surface clean

Remove dust between stages with suitable extraction and cleanup. Replace worn or clogged abrasive instead of leaning harder on the tool. Follow the sander's instructions and keep it controlled on the work; extra pressure is not a substitute for a fresh cutting surface.

Thin veneer deserves particular restraint. You have less material available to correct a mistake than you do on a thick solid-wood board. Inspect often and avoid rounding over corners while chasing a small mark.

After sanding, use the cleaning method specified for your intended finish. If you use a liquid inspection wipe, confirm compatibility and allow the surface to dry as required. Finally, make the first finish trial on a prepared offcut under the same light. It is the cheapest place to discover that the surface needs another pass.

Put this into practice

If the surface becomes rough only after coating, distinguish raised grain under water-based finish from dust nibs in polyurethane before sanding it again.

FAS (First & Seconds) lumber grade. This premium grade represents the finest lumber yield in a log. Generally, the minimum size board is 6" wide by 8' long which yields a minimum of 83 1/3% clear cuttings on its poorest face. F1F (FAS One Face) lumber grade. The best face grades as clear FAS; the worst, as #1 common, containing some knots. Selects lumber grade. Close to a FAS board. A Select board must be a minimum of 4" wide and 6' long and yield a minimum of 83 1/3% clear cuttings, but only on one face with #1 common on the worst face. #...
