French polishing is a hand-applied wood finishing technique that uses shellac dissolved in alcohol, worked into the surface using a polishing pad in thin, overlapping coats. Each coat is built up gradually, filling the wood grain and creating a finish that ranges from a soft, warm sheen to a deep, high-gloss surface depending on the number of coats and the final buffing stage. Because the shellac is applied by hand rather than sprayed or brushed, the finish follows the natural contours of the wood grain and can be controlled precisely, which is why it remains the preferred method for antiques, period furniture and fine cabinetry where a modern lacquer would look out of place.
The process begins with a surface assessment to check the condition of the existing finish, identify any scratches, water rings or worn-through areas, and decide whether a spot repair or a fuller refinish is needed. Preparation follows: the surface is cleaned, any old wax or contamination removed, and pumice pore-filling is carried out to level the grain before the first shellac coat goes on. Colour matching is done at this stage so the new finish blends with the surrounding surface rather than reading as a visible repair. On older and period properties across Essex, original fitted woodwork, staircases and panelling often carry decades of shellac that simply needs reviving rather than stripping, and preparation work determines whether that is possible.
Once the surface is prepared, shellac is applied by pad in thin, stable layers, with each coat allowed to harden before the next is added. The final stage is buffing and burnishing to bring the finish to the agreed sheen level, a stronger gloss for formal furniture or a softer, more muted finish for pieces where a high shine would look wrong. The result is a surface that is smooth and even in normal light, with colour and grain reading consistently across the whole piece. Aftercare is straightforward: shellac responds well to light waxing and is sensitive to water and heat, so clear guidance on both is provided once the work is complete.
