Chemical damage to a veneer tabletop
Lacquer Repair for Chemical (Solvent) Damage on Lacquered Oak Veneer
Step 1: Assess the Damage
- Identify sharply defined patches where lacquer and stain are stripped, exposing bare wood.
- Confirm surrounding finish is sound (no lifting, white blush, or soft edges) and veneer is flat (not raised/warped).
- Ensure the surface is clean and dry before proceeding.
Step 2: Clean the Surface
- Dust off the damaged zone and adjacent area with a soft, dry cloth.
- Avoid water and liquid cleaners; they can swell exposed oak or disturb remaining finish.
Step 3: Remove Loose Finish
- Feather the edge where intact lacquer meets bare wood using 320–400 grit sandpaper.
- Sand lightly with the grain; do not thin or cut through the veneer.
- Remove all loose or flaking finish; vacuum and tack cloth to clear dust.
Step 4: Prepare for Refinishing
- If bare wood looks light/dry or mismatched, apply a matching stain to blend with surrounding colour. Let it dry fully per manufacturer’s guidance.
- Optionally use wood conditioner on very absorbent areas for even stain uptake.
- Mask off adjacent areas to prevent overspray and protect the original sheen lines.
Step 5: Apply New Lacquer
- Choose a clear lacquer matching original sheen (satin, gloss, matte).
- Apply several thin coats by small spray or fine brush, building only within and slightly beyond the repair to blend.
- Allow full dry time between coats; lightly de-nib between coats with 600 grit.
- Maintain dust control and good ventilation.
Step 6: Final Buff and Polish
- After full cure, gently buff with a soft cloth to harmonize the sheen with surrounding finish.
- Optional: apply a high‑quality furniture wax or polish to unify appearance and add protection.
Notes and Tips
- Work with the grain; keep pressure light at edges to avoid witness lines.
- Test stain and sheen on scrap or a concealed spot before committing.
- If the solvent damage extends across a large, highly visible area, or colour/sheen matching is uncertain, consult a professional furniture restorer.
