What is French Polishing?
The Art of French Polishing: A Timeless Finish for Wood
In the world of furniture restoration and fine woodworking, few finishes command as much respect and admiration as French polishing. This traditional technique, which dates back to the early 19th century, remains one of the most beautiful and refined ways to bring wood to life. Renowned for its deep, mirror-like gloss and warmth, French polishing is as much about patience and craftsmanship as it is about skill.
French polishing is a hand-applied finishing technique that uses shellac — a natural resin secreted by the lac bug — dissolved in alcohol. The shellac is applied in many thin layers using a soft pad known as a rubber or fad, made from cotton wadding wrapped in a piece of fine cotton or linen.
Unlike modern finishes that rely on spraying or brushing, French polishing depends on careful, circular or figure-eight motions that gradually build up the surface’s sheen. Each application melts slightly into the previous layer, creating a seamless, glass-smooth finish with incredible depth.
The technique became popular during the Victorian era, especially for fine furniture made from mahogany, walnut, and rosewood. It was the finish of choice for high-end cabinetmakers and piano manufacturers, admired for the way it enhanced the wood’s natural grain and colour.
Over time, as industrial processes evolved and quicker finishes like lacquer and polyurethane took over, French polishing became something of a lost art. Yet today, with the revival of interest in restoration, sustainability, and craftsmanship, it’s enjoying a well-deserved resurgence.
A true French polish is built up slowly and meticulously — it’s not a finish that can be rushed. The basic process involves:
Surface Preparation – The wood must be sanded smooth and any imperfections filled. Cleanliness is essential.
Making the Polish – Shellac flakes are dissolved in methylated spirits (denatured alcohol) to the desired strength.
Applying with a Rubber – The pad is loaded with polish and gently applied in overlapping motions, building up thin coats over several sessions.
Oiling – A few drops of oil (traditionally olive or mineral oil) are added to the rubber to keep it gliding smoothly.
Finishing and Burnishing – After numerous layers and drying time, the surface is polished and “spirited off” to remove any excess oil, revealing a flawless, high-gloss finish.
While it requires time and skill, the results are unmatched. French polishing gives wood an almost three-dimensional clarity — a warmth and depth that synthetic finishes can’t replicate. It’s ideal for antique restoration, heirloom pieces, or any furniture that deserves a truly handcrafted touch.
Beyond aesthetics, it’s also a repairable and sustainable finish. Unlike varnish or lacquer, shellac can be easily re-dissolved and repaired without stripping the entire surface — a quality that makes it perfect for ongoing restoration work.
In an age where speed and convenience often overshadow craft, French polishing stands as a reminder of the artistry and patience that define true craftsmanship. Whether you’re restoring a family heirloom or finishing a bespoke piece, the technique rewards the maker with a finish that speaks of tradition, skill, and respect for the material.
French polishing is not just a method — it’s a dialogue between the maker and the material. Every stroke of the rubber, every subtle adjustment in pressure, builds a relationship between hand, wood, and finish. It’s a process where time, tradition, and technique come together to create something truly timeless.
