French polishing is a traditional method for finishing furniture, widely used on antique pieces. It involves applying a series of fine shellac coats to create a high-gloss finish, enhancing the wood’s appearance and durability.

While French polishing was once the standard finish, modern finishes like cellulose lacquer and polyurethane lacquers are now more common for everyday furniture. Below, I’ll walk you through a classic French polish, but these steps can be adapted for other types of finish.

With patience and practice, French polishing is very achievable for beginners. Timber is forgiving and mistakes in staining or polishing can usually be reversed by washing or sanding, without any permanent damage.

French polishing requires a little bit of knowledge and a lot of practice. I’ve been French polishing for 30 years, and I’m still learning new ways of doing things!

Expert tip: Practising the techniques on spare wood pieces can help build your confidence before tackling larger furniture projects.

Step 1: Preparation

Preparation is key. If you get your preparation correct, everything after that becomes a lot easier.

• Sand by working your way through the grades of paper:
  • For new timber: begin with coarse sandpaper (120-grit) and work up to fine grades (320-grit).
  • For already-sanded wood: start with 240–320 grit.
• Clean: Wipe the surface with a cloth dampened with methylated spirit to remove oils or contaminants.

Step 2: Staining

• Choose your stain type:
  • Water stains
  • Lightfast stains
  • Oil stains (recommended: easy to use and available pre-mixed)
• Test the stain on a small, hidden area like the underside.
• Apply the stain:
  • Use 2 pieces of rag.
  • Wet one rag with stain and wipe over the wood, getting into corners.
  • Use the dry rag to wipe off excess immediately for an even finish.
• Allow stains to dry thoroughly:
  • Check the label (usually 2+ hours).
  • Waiting the full time helps avoid bleeding through.

Expert tip: Oil stains won’t darken if overlapped — great for large surfaces.

Step 3: Sealing

Apply a shellac-based sealer to build the grain and seal the wood:

• Use a high-quality flat brush or polishing mop.
• Apply a generous first coat, let dry for 30 minutes.
• Apply a second coat for a solid base.
• Once dry, lightly sand with 320-grit paper or a sanding sponge for curved areas.

Expert tip: If using an alternative finish like cellulose lacquer, all steps so far still apply. Just switch to the alternative finish now.

Step 4: Applying French Polish

Now it’s time to build those fine layers:

1. Make a polishing pad:
   Ball up a piece of mutton cloth, tuck corners in, dip in French polish (not dripping).
2. Apply thin coats:
   • Run lightly along the grain.
   • Let dry 30 seconds to 1 minute before next coat.
   • Repeat in rounds for a smooth, even finish.
3. Rest: After 15–20 minutes of polishing, let rest for an hour.
4. Sand lightly:
   • Use 320-grit paper to remove small imperfections (not to cut back).
5. Repeat:
   • Keep repeating until you reach your desired finish.

The more you repeat, the more you’ll close the timber grain. Stop earlier for a natural finish or keep going for a full French polish shine.

Step 5: Finishing Touches

If you love the result, you can stop here. Otherwise, to soften the shine, try this:

• Make 2 pads of ultra-fine wire wool (grade 0000):
  • Fold into a cushioned pad.
• Add finishing wax:
  • Lightly move the pad over the surface with the grain.
  • Lubricate with white spirit if needed.
• Buff:
  • Use a dry wire wool pad to clean and even out.
  • Finish by wiping over with a microfibre cloth.

Disposing in an Environmentally Friendly Manner

Disposing the correct legal way requires due diligence.
Check your local authority website for guidance on how, where, and when to dispose of chemicals or chemical-related items.

How to Look After French-Polished Furniture

With moderate use, a French polish can last 10–12 years — or forever with no use.

Maintenance Tips:

• Cleaning:
  Avoid sprays like Pledge. Use a damp cloth with a little washing-up liquid monthly.
• Refreshing the finish:
  Use beeswax polish to restore sheen and remove light marks.

Choosing the Right Finish for Different Applications

French polish is beautiful — but not always ideal. Here’s how to decide:

Durability

• French polish: Best for low-traffic items (e.g., occasional tables).
• Hard lacquers/polyurethane: Best for high-traffic use (e.g., dining tables, stair handrails).

Wood Type

• Softwoods (e.g., pine):
  • Absorb stains deeply.
  • Go light — darker stains can look patchy.
• Veneers:
  • Treat like solid wood.
  • Sand lightly to avoid breaking through the thin layer.
• Hardwoods (e.g., oak):
  • Easier to polish.
  • May present sanding challenges.

Modern Alternatives to French Polish

If French polish isn’t right for your project, try:

• Wax finishes: Natural look, but less durable.
• Cellulose lacquers: Quick-drying and hard.
• Polyurethane lacquers
• Acid catalyst lacquers:
  Extremely durable — professional application recommended.

When to Seek Professional Help

You might need a pro for:

• Applying hard finishes:
  (e.g., polyester or acid catalysts)
• Fixing water damage:
  Can be hard to assess — easy to worsen without experience.
• Deep gouges:
  Light scratches are DIY-friendly, but deeper damage may need expert repair.

Most professionals are open to giving advice, especially on damage repairs. If unsure — ask.
