Misidentifying the Existing Finish

Shellac, Lacquer, or Polyurethane?

Different finishes react differently to solvents and heat. Alcohol softens shellac, lacquer thinner affects lacquer, while polyurethane resists both. Choosing the wrong polish can haze, smear, or soften the surface, destroying clarity and wasting effort.

A Simple Spot Test Saves a Project

Before you touch a pad, test in a hidden area. A tiny swab with alcohol or lacquer thinner tells the truth. I once saved a century-old sideboard using this quiet, fifteen-second experiment.

Ask, Document, and Patch-Test

If possible, ask the previous owner or maker. Photograph, label, and keep notes. Then patch-test your compound, pad, and speed. Share your test methods in the comments to help others avoid guesswork.

Edges and High Spots Disappear First

Raised edges receive more pressure and heat, so they vanish before flat fields. Tape them, lighten touch, and reduce passes. Protect decorative ridges like heirlooms, because once rounded, that crisp shadow never truly returns.

Respect the Grit Ladder

Skipping grits forces the next step to work too hard, creating scratches that never fully leave. Move steadily through grits, wipe between stages, and inspect under raking light. Patience builds gloss; shortcuts build regret.

Hand Pressure Beats Heavy Machines

Machines multiply mistakes. Use foam blocks, gentle hands, and consistent strokes, especially near joints, moldings, and veneers. Share your favorite hand-sanding rituals—someone will learn a trick that saves their antique tomorrow.

Wrong Compounds, Pads, and Swirl Marks

Match Compound to Finish Hardness

Hard finishes need cutting power; softer films require mild abrasives to avoid smearing. Start less aggressive and step up only if needed. Document what worked, then repeat with confidence across similar pieces.

Clean Pads, Clean Results

Dirty pads grind in old debris and oil, scratching instead of polishing. Clean or replace pads often, prime them lightly, and mark dedicated pads for each compound. Your clarity will thank you immediately.

Slow Speed, Cool Surface

High speed builds heat, softens finishes, and imprints swirls. Keep the pad flat, reduce RPMs, and mist the pad if recommended. If the surface feels warm, pause—gloss grows in cool patience.

Contamination: Silicone, Wax, and Dust

Silicone from old polishes can repel your compound, leaving crater-like defects. I once chased fish-eyes for hours until a proper degreaser and a silicone remover reset the surface. Prevention beats chasing defects.

Too Much Wax Mutes the Grain

Heavy wax layers trap dust, streak, and hide the wood’s chatter. Thin coats, buffed well, beat constant rewaxing. Try quarterly touch-ups instead of weekly rituals and watch the grain sing again.

Mixing Products Can Muddy the Finish

Silicone-laden sprays layered over natural waxes or oils can smear and resist future polishing. Stick to one system, record product names, and test compatibility on a discreet corner before committing everywhere.
