Beginner’s guide · Make & create

Build a finish
in patient thin layers.

French polishing lays many thin shellac films with a cloth rubber to create depth and clarity on suitable wood. Practise on a flat veneered sample, not valuable furniture, and manage solvent vapour carefully.

Quick answer

Practise prepared polish on a flat sample

Start with a clean flat hardwood or veneered board, ready-made French polish and a cotton-covered rubber. Build very thin sessions over a well-prepared surface rather than trying to flood on gloss.

The quick answer
  1. 01

    Identify the existing finish and wood before applying shellac to furniture. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  2. 02

    Prepare the surface flat and dust-free because polish amplifies scratches rather than hiding them. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  3. 03

    Charge the rubber lightly and keep it moving before it begins to drag. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  4. 04

    Allow sessions to dry and harden instead of repeatedly working a sticky surface. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

  5. 05

    Test colour and compatibility on scrap or a hidden area before committing to an object. Note the material, setting or measurement used so the result can be repeated or changed for a reason.

What to expect

The shine comes from preparation and film control

French polish is not one heavy coat; it is a sequence of filling, bodying and refining that makes contamination and impatience visible.

01

Surface preparation

Old wax, silicone, grease or coarse sanding scratches can cause fish-eyes and uneven clarity. Diagnosis comes before polishing. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

02

Rubber charge

Too much polish leaves ridges and sticking; too little causes drag. The cloth should lay a whisper-thin track. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

03

Environment

Dust, temperature and humidity affect flow and drying. A clean ventilated room matters more than a giant product collection. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

04

Durability

Shellac is beautiful and repairable but sensitive to heat, alcohol and standing water compared with some modern finishes. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

03

Core method

Make the wood ready before making it glossy

Choose a practice piece

Use a flat stable sample with known timber and no sentimental or monetary value, then inspect it under raking light. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Prepare progressively

Remove contamination appropriately, sand through sensible grades with the grain and clear dust without introducing polish residue. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Build the body

Form a firm cotton-wool core inside clean cotton cloth, charge sparingly and apply overlapping passes without stopping on the surface. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Refine and rest

Let sessions dry, address defects only after hardening and use the maker’s spiriting-off or final rubbing guidance. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

First project

Polish one flat board and keep a control half

Masking part of the board provides a direct before-and-after reference for preparation, colour and sheen.

  1. 01

    Inspect and test

    Confirm the timber and prior treatment, clean a small area with the recommended method and check for compatibility. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  2. 02

    Prepare the surface

    Work through appropriate abrasives with the grain, protect thin veneer and remove dust completely. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  3. 03

    Make the rubber

    Wrap a clean absorbent core with smooth cotton, twist a comfortable handle and test its face on scrap. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  4. 04

    Apply thin sessions

    Charge sparingly, keep the rubber moving in controlled passes and stop before it drags or deposits heavy ridges. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  5. 05

    Let it harden

    Allow proper drying, inspect in raking light and follow the product system for final refining rather than chasing gloss while tacky. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

06

What can wait

What can wait until the first result

Valuable antiques, curved carvings and mixing shellac from flakes add identification and technique risks best postponed.

  • 01

    Antique furniture

    Original finishes, veneer and historical value demand conservation judgement before any cleaning or recoating. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  • 02

    Raw shellac flakes

    Mixing gives control later; prepared polish establishes application feel without calculating cut strength. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

  • 03

    Large dining table

    Heat, alcohol and water exposure make use requirements important. Prove the finish on a portable sample first. For french polishing, check this deliberately while the work is still easy to alter; correcting it after the next stage usually costs more time or materials.

Preparation, rubber charge and thin film building become visible.
02

Mix deliberately

£25–£70 extra

Fresh shellac flakes, appropriate solvent and accurate containers

Cut, colour and freshness can suit the timber and working style.
03

Refine surfaces

£30–£120

Grain filling, finer abrasives and raking task light

Open pores and minor defects can be handled systematically.
04

Restore responsibly

Variable

Finish-identification skill or conservation tuition

Existing furniture can be treated without casually erasing original material.
08

Safety & care

Control solvent vapour and ignition

Traditional French polish is commonly alcohol based and must be treated as a flammable finishing material.

  • Work with strong ventilation, keep all flames, heaters, sparks and smoking far from polish and vapour. Follow the current instructions supplied with the exact material or tool.
  • Wear protection specified by the safety data and avoid prolonged skin contact. Follow the current instructions supplied with the exact material or tool.
  • Store polish in its labelled original container and manage used cloths under current fire and disposal guidance. Follow the current instructions supplied with the exact material or tool.
  • Do not sand old unknown coatings without assessing possible hazardous dust and using appropriate extraction and respiratory protection. Follow the current instructions supplied with the exact material or tool.

Outside help

When outside help earns its place

A manufacturer demonstration is enough for a practice board. Hands-on tuition is sensible before valuable furniture, finish removal or traditional grain filling.
