How Long Does French Polishing Take?

Approx. 7 min read

French polishing is known for its beautiful, mirror-like finish — but it's also one of the most time-consuming wood finishing techniques. Unlike modern spray or brush-on coatings, French polishing is done entirely by hand, building up dozens of thin layers of shellac over several sessions.

The exact time it takes depends on the size of the piece, the wood type, and the condition of the surface. Below is a detailed breakdown.

1. General Timeframe

On average, French polishing takes:

2–5 days for small items

(e.g., bedside tables, dining chairs, small cabinets)

1–2 weeks for large furniture

(e.g., dining tables, antique wardrobes, writing desks)

2–3 weeks for pianos or complex, carved pieces

(grand pianos, intricate antiques, multi-panel furniture)

This timeline includes preparation, pore filling, polishing sessions, drying times, and final finishing.

2. Why French Polishing Takes Time

French polishing is not a single coat — it's a layering process.

Here's what makes it time-intensive:

  • Multiple coats: Often 20–30+ ultra-thin layers
  • Drying time: Shellac dries fast, but layers must be built carefully
  • Grain filling: Pumice and shellac are used to create a smooth base
  • Spiriting off: Refining the finish requires precision and patience
  • Handwork: Every stroke is done manually with a polishing pad

The process simply cannot be rushed without affecting the final shine and clarity.

3. Influence of Wood Type

Different woods take different times.

Open-grain woods (slower):

  • Mahogany
  • Walnut
  • Oak

These require more pore-filling, adding extra hours or days.

Tight-grain woods (faster):

  • Maple
  • Cherry
  • Birch

These need fewer preparation steps.

4. Condition of the Furniture

The starting condition significantly affects the polishing time.

Takes longer if:

  • The old finish must be stripped
  • The wood is damaged or uneven
  • Deep scratches need repairing
  • Veneer needs stabilising
  • Water or sun damage must be corrected

Faster if:

  • The surface is clean and ready
  • Only refinishing is required, not restoration

Most antique pieces require detailed restoration before polishing even begins.

5. Size and Complexity of the Piece

A simple flat tabletop will polish much faster than:

  • Carved legs
  • Turned components
  • Raised panels
  • Ornamental details
  • Large surfaces (e.g., grand pianos)

More surface area = more layers = more working time.

6. Drying and Curing Time

French polish dries quickly, but curing takes longer.

Drying:

Shellac dries within minutes between coats.

Curing:

The finish continues to harden over 7–14 days.

Many professionals recommend avoiding heavy use or placing objects on the surface during this curing period.

7. Can French Polishing Be Done Faster?

Experienced polishers can work efficiently, but the process still requires:

  • Repeated sessions
  • Correct timing
  • Layer building
  • Rest periods

Trying to shorten the process usually leads to:

  • Stickiness
  • Cloudy finish
  • Streak marks
  • Uneven gloss

So while it can be done efficiently, it cannot be rushed without compromising quality.

Summary: How Long Does French Polishing Take?

French polishing typically takes:

  • 2–5 days for small pieces
  • 1–2 weeks for medium to large furniture
  • 2–3 weeks for pianos and high-value antiques

The timeline depends on preparation, wood type, condition, and detail. The result, however, is a luxurious, long-lasting, mirror-like finish that makes the time investment completely worthwhile.
