Stripping Paint – Techniques for Wood Preservation
Taking it Off (The Right Way)
Old paint can hide a multitude of sins - or treasures. Underneath that flaky, chipped exterior may be beautiful woodwork just waiting to shine again. But removing paint from historic windows and doors isn’t just a matter of elbow grease - it’s about technique, safety, and preservation.
In this week’s post, we’ll walk through the safest and most effective methods for stripping paint from historic wood without damaging what’s beneath.
Why Strip Paint in the First Place?
✔️ Restore crisp details in moldings, panels, and sash profiles
✔️ Remove lead-based paint hazards
✔️ Allow for better adhesion of new paint or stain
✔️ Reveal original wood for staining or clear-coating
Whether you’re going for a full bare-wood look or just prepping for a repaint, getting down to a clean surface is key.
Safety First: Lead Paint is Likely
If your home was built before 1978, there’s a high chance that paint layers contain lead.
🔺 Always test for lead before starting (available in hardware store kits)
🔺 Wear proper PPE: respirator, gloves, safety goggles
🔺 Work in a ventilated area—outdoors or with HEPA filtration if inside
🔺 Contain debris and clean up thoroughly with a HEPA vac
Best Methods for Stripping Paint (Preservation-Approved)
1. Infrared Paint Remover (Low-Heat Stripping)
Gentle and effective, this method uses infrared heat to soften paint without burning the wood.
✅ Safe on lead paint (minimizes dust)
✅ Ideal for intricate carvings and delicate moldings
✅ Less risk of scorching compared to traditional heat guns
⚠️ Keep the tool moving to avoid drying or warping the wood.
2. Chemical Paint Strippers (Citrus-Based or Caustic)
These soften multiple layers of paint for easy scraping.
✅ Good for hard-to-reach spots or ornate areas
✅ Gel versions cling to vertical surfaces
✅ Citrus-based options are safer and less toxic
⚠️ Always neutralize caustic strippers per manufacturer’s instructions.
3. Hand Scraping
Old-school, but still effective. A sturdy paint scraper removes flakes and softened paint.
✅ Best for flat, accessible areas
✅ Gives you tactile feedback - you can feel when you’re hitting good wood
⚠️ Don’t dig too hard; you’ll risk gouging the surface.
4. Detail Tools for Moldings
For profiles and crevices:
Dental picks
Contour scrapers
Steel wool or bronze brushes
These let you chase the paint out of the nooks and crannies without damaging detail.
What to Avoid
🚫 Sanding lead paint without a HEPA setup - it creates dangerous airborne dust
🚫 Blow torches or high-heat guns - they’ll burn the wood (and possibly your house)
🚫 Random orbital sanders on detailed surfaces - they’ll round off historic profiles
When to Go to Bare Wood (and When Not To)
✅ Go bare if:
The original finish has failed
You want to stain the wood
You need to repair cracks or rot
🛑 Leave layers if:
The paint is stable and you just need a refresh
You’re not trying to change color or finish
The details are at risk from over-stripping
Sometimes just feather-sanding and repainting is all that’s needed.
Finishing Strong
Once stripped:
Sand lightly with fine-grit paper (if safe to do so)
Clean thoroughly with vacuum and tack cloth
Prime with an oil- or shellac-based primer for durability
Use high-quality exterior-grade paint or stain to finish
Conclusion: Strip Thoughtfully, Preserve Beautifully
Paint stripping isn’t just about removing the old - it’s about revealing the legacy underneath. With the right tools, techniques, and a healthy respect for safety, you can uncover rich wood grain, detailed carvings, and crisp lines that bring your historic home back to life.
Preservation begins with knowing what to keep - and how to reveal it.
