How to Strip Paint from Wood: Restoring a Thonet Chair 2026

Stripping paint from wood is a delicate operation that removes old layers of varnish or paint, allowing you to treat the wood with fresh finishes. This careful work is essential to restore the splendor of a classic Thonet chair. The first step: stripping the wood.

Use solutions that soften the paint without damaging the wood and evaporate quickly. The removal of all layers is done with spatulas, scrapers, and wood shavings saved from previous DIY projects. Finish the stripping with a thorough wash of all surfaces. Once the wood is dry, sand it with fine-grit sandpaper to eliminate any irregularities.

Stripping Wood: Special Care for the Seat

Remove old paint using a stripper based on inhibited chlorinated solvents (not caustic soda), applied in a thick layer over all surfaces. The solvent's action is not aggressive toward the wood or water-based adhesives, but it can be harmful to you, so work in a well-ventilated area or wear a painter's mask.

After about 10 minutes, bubbles form on the paint, which can be scraped away with spatulas or wood shavings. Finish the seat with fine-grit sandpaper, taking care to preserve the raised patterns. For a complete home refresh, explore our home improvement collection for tools and supplies.

Stripping Wood: Removing Dirt, Wax, and Old Finishes

The paint softened by the gel doesn't always come off the wood on its own, especially with transparent finishes or lacquers. It must be meticulously scraped while still soft using variously shaped scrapers or large wood shavings.

Use a sponge to wash away the stripper residue, which also raises the wood's grain so it can be easily removed in the next step. When the wood is completely dry, sand the surfaces with fine-grit sandpaper (over 200 grit) to eliminate any roughness that could cause defects in the final lacquer coat.

Frequently Asked Questions

What is the best way to strip paint from a Thonet chair?

Use a solvent-based stripper with inhibited chlorinated solvents, apply it thickly, wait 10 minutes for bubbles to form, then scrape gently with a spatula or wood shavings. Always wear a mask and work in a ventilated area.

Can I use caustic soda to strip wood?

No, caustic soda can damage the wood and water-based glues. Stick to inhibited chlorinated solvent strippers for safe and effective results.

How do I remove stubborn paint residue after stripping?

Wash the surface with a sponge to remove stripper residue and raise the wood grain. Once dry, sand with fine-grit sandpaper (200+ grit) to smooth everything out.

What should I do if the paint doesn't bubble after applying stripper?

Apply a thicker layer of stripper and wait a bit longer. If it still doesn't bubble, the paint may be a tough lacquer—scrape it manually while the stripper is still wet.
