French Polish Restoration: Shellac Recoating Guide UK

Quick Answer: French polish is shellac dissolved in methylated spirit, built up in many thin coats (10–30) using a "rubber" pad of cotton wool wrapped in lint-free cloth. Restoration involves cleaning (white spirit and fine wire wool 0000), spot-repair, then "fadding" new polish over old surface. Full re-polish takes 8–20 hours per medium piece. Original Victorian/Georgian furniture requires this finish to retain provenance and value.

Summary

French polishing is the highest-grade traditional wood finish — used on Georgian and Victorian furniture, period staircases, pianos, and high-end joinery. Modern lacquers are tougher and faster but lack the depth, warmth and repairability of shellac. A polished surface refreshed by skilled hand has unrivalled clarity; an over-restored or stripped antique loses 30–60% of its value.

Restoration sits at the high-margin end of decorating: £50–£120 per hour rates are normal for skilled French polishers, and a single antique table can be a 15–30 hour job. Most general decorators don't take French polishing jobs because the technique requires apprenticeship; those who do command serious premium.

This article covers the basics for tradespeople who need to assess a job, quote responsibly, or sub-contract. It is not a full apprenticeship. Genuine high-value antique work should be referred to BAFRA (British Antique Furniture Restorers Association) approved restorers.

Detailed Guidance

Assessment first — value vs cost

Before quoting any French polish restoration:

  1. Identify the piece — Period, maker (look for stamps, labels), wood species. Use online auction catalogues (Christie's, Bonhams) or BAFRA referral.
  2. Estimate value — A £200 reproduction Victorian-style table doesn't warrant £800 French polish restoration. A genuine £8,000 William IV mahogany table does.
  3. Damage assessment — Surface marks only? Deep scratches into wood? Veneer lifting? Each adds complexity.
  4. Original finish? — If polish is original, full strip destroys value. Refresh only.

Refer to BAFRA for pieces over £3,000 estimated value. Their certified members carry insurance and provenance documentation.

The shellac itself

Buy quality flakes from specialist suppliers:

Mix from flakes for best results — pre-mixed shellac has limited shelf life (6–12 months from manufacture; check date). Flakes last 5+ years sealed.

To mix 2lb cut: 250g shellac flakes + 1 litre methylated spirit. Dissolve overnight in glass jar, agitating occasionally. Strain through fine muslin before use.

The rubber (pad)

Inner core: cotton wool (cosmetic grade, no synthetic). Size: tennis-ball to fist-size. Outer cover: linen or fine cotton lint-free cloth, folded around core forming pear-shape.

Charge the inner core with polish through the cover — never apply polish directly. The cover regulates release rate. As the rubber ages it darkens; a "broken-in" rubber is more controllable than new.

Store the rubber in a sealed jar with a few drops of meths between uses — keeps it pliable for weeks.

The technique stages

French polishing progresses through stages:

  1. Bodying up / fadding — Initial 10–15 coats with rubber in circular and figure-of-eight motions. Builds the polish film.
  2. Stiffening — Polish becomes harder; reduce shellac concentration with more meths.
  3. Spiriting off — Almost pure meths with a hint of polish; removes pad-lines and oil residue.
  4. Burnishing (optional) — Final friction with clean cotton to bring up mirror finish.

Between sessions: 24-hour rest minimum. Polish needs to harden before next layer adheres properly. Rushing creates "bloom" — milky cloudiness that's almost impossible to remove.

Common faults and fixes

Restoration vs full re-polish

Restoration (refresh over existing):

Full re-polish (strip first):

Restoration is the right answer for 80%+ of jobs. Strip only when finish is beyond repair (deep damage, severe sun bleaching, large veneer loss).

Working environment

French polish needs:

Outdoor or site polishing is impractical. Take pieces to workshop for premium results.

Insurance and provenance

For high-value antiques (over £3,000):

A dropped antique table without insurance can financially destroy a small trade business.

Frequently Asked Questions

Can I sub-contract French polishing?

Yes — many general decorators do. Find a local BAFRA member or specialist polisher. Mark up 15–25% on their fee. The relationship benefits you for ongoing antique work.

Will French polish stand up to use?

It's softer than modern lacquer. Won't withstand hot mugs, alcohol spills, or heavy daily use without marks. Properly maintained (waxed quarterly, polished as needed) lasts decades. Use modern lacquer or polyurethane on heavy-use surfaces (kitchen, bar, dining table-top). Use French polish on lower-impact pieces (sideboards, displays, side tables).

Is there a faster modern equivalent?

Modern brush-on shellacs (Liberon French Polish in a tin) approximate the look in fewer coats. Quality is good but won't match true rubber-applied finish. For "looks French-polished" budget jobs, brush-on shellac is acceptable. For genuine restoration, no shortcut.

Can I strip French polish without damaging the wood?

Yes — methylated spirit dissolves shellac without affecting the wood. Apply with brush or cloth, polish lifts within minutes. Scrape with plastic scraper. Final clean with meths-soaked cloth. Wood emerges clean. This is the safest stripping method for any old wood finish.

What's the difference between French polish and shellac?

French polish IS shellac, but applied in a specific way (rubber, multi-coat). "Shellac" sold in tins is the same material — usually brushed on, gives a similar finish but less depth. True French polish is the method, not the material.
