French Polishing Explained: What It Is, How It’s Done and What It Costs

What Is French Polishing?

French polishing is a traditional technique for applying shellac to wood, building up dozens of wafer thin layers by hand until the surface reaches a deep, glass smooth shine. It’s worth being clear on this from the start: French polish isn’t a product you buy off a shelf. It’s a method, using shellac as the material and a cloth pad as the tool, and that distinction is why it looks and behaves so differently from a sprayed or brushed varnish.

The technique dates back to the 15th century, but it wasn’t until the 18th century that it really took hold, when wealthy Victorians used it to enhance and protect expensive furniture, most commonly mahogany. The high gloss finish it produces gives wood a rich, deep colour that’s hard to replicate with modern coatings. It’s also a genuinely difficult skill to master. Becoming a proficient French polisher takes years of practice, and like a lot of specialist trades, the number of people who still do it properly is shrinking.

My grandfather taught me how to French polish, and I’ve applied the technique to a few older antique items over the years, including my grandparents’ old side table. It’s not something I use regularly though, the process is slow, unforgiving of mistakes, and takes a lot of patience to get an even build up, so for most of my own projects I’ll turn to it sparingly rather than as a go to finish.

Why Choose French Polishing?

There are several situations where French polishing genuinely earns its reputation. Musical instruments, pianos in particular, look stunning once treated, with the finish giving them a classic, expensive appearance that’s part of why so many high end instruments are still finished this way.

It’s also used to restore wooden floors and staircases, where the treatment creates a warm, classy feel and the durability of a well built up French polish holds up surprisingly well in areas of heavy footfall.

But antique or period furniture is probably the most common use, and restoring older pieces back to their former glory is one of the most satisfying parts of the process, as my grandparents’ table proved to me firsthand.

Step-by-Step Guide: How to Apply French Polish to Your Furniture

What I used for a small side table top (40cm x 40cm):

• Shellac flakes: 50 to 60g, dissolved in methylated spirit at roughly a 2lb cut (around 240g per litre) to make up about 250ml of shellac solution. That’s enough to build several thin coats over the whole surface with a bit of spare in case of mistakes. (Find Shellac Flakes on Amazon here)
• Methylated spirit: around 500ml in total, roughly 250ml for mixing the shellac itself, and the rest kept aside for fadding between coats and the final spiriting off pass.
• Polishing mop: one small mop brush (around 25mm/1 inch), which is plenty for an area this size. (Various sizes available here).
• Rubber pad (fad): a golf-ball-sized wad of cotton wadding, wrapped in a piece of soft, lint-free linen or cotton cloth, roughly 15cm square.
• Fine abrasive paper: two or three sheets, 400 to 600 grit, for the initial levelling pass.
• Light mineral or linseed oil: a teaspoon or so is more than enough. Used sparingly, just a light film on the pad, to stop it dragging as you body up.

A tabletop this size is a good, forgiving piece to start on if you’re learning the technique. Small enough to work through in a few sessions, but big enough to get a proper feel for building up thin coats evenly, which is the part that takes the most practice.

French Polishing Step-by-Step

Work in a warm, dry, well ventilated room. Shellac and meths fumes build up quickly in a closed space, and I’ve found damp or cold conditions will stop the finish curing properly.

1. Prepare the surface. Strip back any old finish to bare wood and sand it smooth. French polish shows every flaw underneath it, so any scratches, old wax, or uneven patches left in now will still be visible once the shine goes on.
2. Fill the grain. On open grained woods like oak or mahogany, work a grain filler or a mix of shellac and fine pumice into the surface before you start building layers. Skip this step and you’ll spend far longer trying to achieve a flat, glass smooth finish later on.
3. Apply the initial coats. Using the polishing mop, lay down very thin coats of shellac in the direction of the grain. Let each one dry and harden fully before adding the next. This early stage is about sealing the wood, not building shine.
4. Sand back lightly. Once the shellac has hardened, cut it back with a fine abrasive paper. This levels the surface and gives the next layers something to key into.
5. Start bodying up. Switch to the rubber pad and begin building the finish in earnest, working in overlapping figure of eight movements along the grain. A touch of oil on the pad helps it glide without dragging or sticking. Keep each layer thin. The depth in a French polished finish comes from dozens of thin coats, not a handful of thick ones.
6. Fad in each layer. After every coat, dab a small amount of methylated spirit onto the hardened surface to soften the top of the previous layer slightly. This lets the new coat melt into what’s underneath rather than sitting on top of it, which is what gives French polish its seamless, built up depth rather than a stack of separate layers.
7. Repeat until the shine builds. Keep alternating bodying and fadding, letting each layer harden before the next. This is the slow part. I’ve found getting an even, streak free build can easily take several sessions over a few days, not an afternoon.
8. Spirit off. Once you’re happy with the depth of shine, finish with a very light pass of clean spirit on the pad to remove any remaining oil haze and bring up the final gloss. This last step is what separates a good finish from a great one.
9. Buff if needed. A soft cloth or polishing pad can be used to gently enhance the sheen once everything has fully cured.

Even with the steps laid out, French polishing is a skill that takes real practice to get right. I was taught by my grandfather, and it still took me a fair few attempts before I was happy with the results on my own pieces. If you’re working on something valuable, an antique, an heirloom, an instrument, I’d usually recommend getting a professional French polisher involved rather than learning on the piece itself.

Here’s a great video demonstrating the process.

How Much Does French Polishing Cost?

Prices vary a fair bit depending on size, condition, and how much prep work is needed, but as a rough UK guide:

• Small items (a single chair, a small box or picture frame): roughly £70 to £150
• A table or sideboard: typically £180 to £350, more for larger dining tables or pieces with separate leaves
• Full restorations on damaged or heavily worn antique pieces: £250 to £550+, once stripping, repairs, and colour matching are factored in

Most French polishers work on a fixed quote rather than a straight hourly rate, though where hourly pricing is used it tends to sit around £20 to £25 per hour. The final figure comes down to a handful of things:

• Condition – a piece that just needs a refresh costs far less than one with water damage, deep scratches, or years of built up wax and grime to strip back first
• Wood type and detail – open grained or heavily carved pieces take longer to fill and finish evenly than a flat, closed grain surface
• Antique vs. modern – genuine antiques often need colour matching and careful repair work alongside the polishing itself, which adds to the price
• Collection and delivery – some polishers charge extra to collect larger pieces, especially outside major cities

It’s always worth getting two or three quotes before committing, and asking what’s included, materials, any repairs, and the number of coats, so you’re comparing like for like rather than just a headline figure.

If it’s a small, low value piece and you’re happy to accept an imperfect result while you learn, DIY is a reasonable way in. But for anything with real sentimental or antique value, my own experience taught me how easy it is to get an uneven finish on your first few attempts, so I’d lean towards a professional for anything you’d be gutted to get wrong.

Which Woods Benefit From French Polishing?

French Polishing is best suited to darker woods that have a fine grain. These woods possess inherent qualities that beautifully complement the French polishing technique. Here are some common wood types that benefit from French polish:

1. Oak: Oak is a popular choice for French polishing due to its distinctive grain patterns and durability. The French polishing technique can enhance oak’s rich, warm tones, resulting in a timeless and elegant finish.
2. Cherry: Cherry wood is known for its beautiful reddish-brown hue and fine, straight grain. French polishing can enhance the natural beauty of cherry wood, bringing out its warmth and depth.
3. Maple: While maple has a light colour and a relatively closed grain, it can still be successfully French polished. The technique can help highlight the subtle patterns and figuring present in the wood, creating a smooth and glossy surface.
4. Ebony: Ebony wood is highly prized for its dark colour and smooth texture. French polishing can accentuate the luxurious appearance of ebony, providing a deep lustre and enhancing its natural richness.
5. Sapele: Sapele is an African hardwood with a reddish-brown colour and an interlocked grain pattern. French polishing can bring out the depth and complexity of Sapele wood, giving it a refined and polished look.
6. Ash: Ash wood possesses a light colour and a distinctive grain pattern. French polishing can enhance the natural beauty of ash, emphasising its unique features and providing a glossy, elegant finish.
7. Walnut: Walnut wood is highly regarded for its rich, dark brown colour and attractive grain patterns. French polishing enhances the natural beauty of walnut, creating a deep, lustrous finish that brings out its warmth and character.
8. Rosewood: Rosewood is prized for its exquisite reddish-brown hues and unique grain patterns. French polishing can intensify the deep, luxurious tones of rosewood, producing a smooth, reflective surface that accentuates its natural elegance.
9. Mahogany: Mahogany is a classic choice for furniture, known for its reddish-brown colour and straight, interlocking grain. French polishing enriches the warm, reddish tones of mahogany, giving it a refined and timeless appearance.

While French polishing is often associated with darker woods, it can still be applied to lighter woods such as Pine or Teak. However, these woods have different characteristics that require specialised treatments. For lighter woods, specialist waxes and oils are available that are perfect for restoring and protecting these types of surfaces. These products are specifically formulated to nourish the wood, enhance its natural colour, and provide a protective layer against wear and tear.

1. Pine: Pine is a light-coloured wood with a distinct grain pattern. Although French polishing can be used on pine, it may require additional steps to achieve a smooth finish due to its more open grain. Alternatively, specialist waxes and oils designed for pine can help enhance its natural beauty, providing a protective layer while preserving its light and airy appearance.
2. Teak: Teak is known for its durability and resistance to moisture, making it a popular choice for outdoor furniture. While French polishing can be applied to teak, it is important to note that teak naturally weathers to a silver-grey patina when exposed to the elements. In the case of teak, specialised teak oils and finishes are commonly used to protect and maintain its natural colour and longevity.

By using the appropriate treatments and products tailored to lighter woods, restoring and protecting these surfaces effectively is possible, enhancing their beauty and ensuring their longevity.

What Are the Benefits of French Polishing?

French polishing has been around since the 15th century, and it’s still chosen over modern finishes for good reason, but it comes with real trade-offs too. Here’s how it stacks up.

Pros of French Polishing

1. Environmentally friendly. Shellac is a naturally occurring resin, non-toxic and renewable, with a far lower environmental footprint than most synthetic varnishes and lacquers.
2. Unmatched finish. In the hands of a skilled polisher, French polish produces a depth, warmth, and richness of colour that modern finishes struggle to match. When I finished my grandparents’ side table, what struck me most was how much the grain seemed to come alive underneath the polish, a depth I haven’t managed to get from a varnish or oil finish on similar pieces.
3. Repairable, not just replaceable. Scratches, dull patches, and general wear can usually be worked back in by a polisher rather than requiring the whole piece to be stripped and refinished from scratch. I’ve found this is one of the biggest practical advantages over sprayed lacquer, which often needs a full redo once it’s damaged.
4. Minimal mess. The process produces very little dust or debris compared to sanding back and spraying a modern finish, so it can often be done in place without moving or dismantling the furniture.

Cons of French Polishing

1. Fragile finish. Shellac is soft compared to modern varnishes and lacquers. It marks easily from heat, water rings, and alcohol spills, so coasters and placemats aren’t optional on a French polished surface. I learned this the hard way with a mug left without a coaster on one of my early pieces, a ring mark that took a fair bit of rework to blend out.
2. Time intensive. Building up dozens of thin coats by hand takes real time and skill. Every piece I’ve done has taken far longer than I expected going in, which is exactly why it’s not a technique I reach for on a regular basis.
3. Needs upkeep. Unlike a sprayed lacquer that’s largely fit and forget, a French polished piece benefits from occasional re-polishing or touch ups to keep it looking its best, especially on surfaces that see regular use.
4. Not built for hard wear. On high traffic surfaces, worktops, hallway furniture, anything that takes daily knocks, French polish won’t hold up as well as a modern, more resilient finish.

Weighing these up matters more than picking a “winner.” A prized antique or a piano is exactly where French polish’s strengths shine. A dining table your kids do homework on every night is a different conversation.

Comparison to Other Finishing Techniques

Against varnishing, lacquering, or staining, French polishing stands apart in a few clear ways.

1. Finish quality. Built up from many thin layers of shellac, a French polished surface reaches a depth and smoothness that’s hard to match with a sprayed or brushed finish, the level of detail is what gives it its reputation for elegance.
2. A more natural look. Where varnishes and lacquers can sit on the surface with a slightly plastic sheen, French polish lets the wood’s own grain, depth, and colour show through, giving a more organic, tactile result.
3. Repairability. Scratches and wear can typically be blended back in by a skilled polisher rather than requiring a full strip and refinish, particularly valuable for antiques or pieces with sentimental worth.
4. The trade-offs. It’s a slower, more labour intensive process than modern finishes, and while durable with proper care, it’s less resistant to scratches, heat, and moisture than a varnish or lacquer, so it suits considered, lower traffic pieces better than everyday hard wear.

Shellac’s natural, low toxicity composition also makes it a genuinely eco-friendlier choice than many synthetic alternatives, worth factoring in if that’s a priority for your project.

What Is a French Polisher?

A French polisher is a specialist craftsperson trained in applying French polish, rather than someone who’s picked it up as a general finishing skill. It’s a trade in its own right, traditionally learned through a long apprenticeship, and it takes years of hands-on practice before someone can consistently produce a flawless, mirror-like finish. My grandfather taught me the basics himself, and even so, it took a fair few attempts on my own pieces before I was happy with the results, which gives you a sense of how much further a full apprenticeship goes.

Most French polishers work on antique furniture restoration, pianos, and high-end joinery, where a refined, traditional finish matters more than speed or cost. Many also specialise further, some focus on colour matching and antique restoration, others on new furniture or instrument finishing.

If you’re looking to hire one rather than take it on yourself, it’s worth asking to see examples of previous work, ideally on a similar wood or piece type to yours, and getting a written quote that spells out what’s included. See the cost guide above for a rough sense of what to expect to pay.

French Polish vs. Varnish: Which Is Best?

Quick answer: French polish gives a deeper, warmer finish and is ideal for antiques and fine furniture, but it’s fragile and needs upkeep. Varnish is far more durable and practical for everyday, high-use pieces, but can’t match French polish’s depth and character.

	French Polish	Varnish
Application	Thin layers of shellac built up by hand with a rubbing pad, using circular motions. Slow and skill dependent.	Brushed, sprayed, or wiped on as a resin and solvent mix. Faster and more forgiving to apply.
Appearance	Warm, deep, richly glowing finish that enhances the wood’s natural grain. Associated with high end, handcrafted furniture.	Clear, glossy protective coating. Enhances colour and texture but with less depth and warmth.
Durability	Delicate. Marks from heat, water, and knocks, and needs regular touch ups, especially in high-traffic spots.	Robust and protective, resistant to scratches, moisture, and UV. Needs far less maintenance.
Best suited to	Antiques, pianos, fine furniture, intricate woodwork.	Everyday furniture, floors, outdoor and marine surfaces, anything that needs to handle daily wear.

The real difference comes down to what the piece needs to do. French polish is a finish you choose for how it looks and feels, not for how hard it can be worked. Varnish is the opposite, chosen for resilience over depth of character.

In my own experience, that’s exactly how I decide between the two. Anything that’s going to take daily use, a kitchen table, a hallway console, gets varnish or a modern lacquer without much thought. It’s only for pieces I want to look their absolute best, like my grandparents’ side table, that French polish earns the extra time and care it demands.
