How to Strip Paint from Wood Floor

Stripping paint from a wood floor is a bigger undertaking than stripping furniture, but the result — beautiful natural wood grain revealed beneath layers of old paint — is worth the effort. Whether you're dealing with a few painted boards or an entire room, here's how to approach wood floor paint stripping safely and effectively.

Tools You'll Need

• Citristrip paint stripping gel — safe for wood floors, effective on multiple paint layers
• Paint scraper set — wide scrapers for open floor areas, narrow for edges
• Sandpaper assortment — for sanding after stripping
• Respirator mask — essential for chemical strippers and sanding
• Chemical resistant gloves
• Safety goggles

Important: Test for Lead Paint First

If your floor was painted before 1978, test for lead paint before stripping. Lead paint test kits are available at hardware stores. If lead is present, follow EPA guidelines for lead-safe work practices or hire a certified lead abatement contractor.

Method 1: Chemical Stripping (Best for Preserving Wood Grain)

1. Apply a thick coat of Citristrip to a manageable section of floor (about 4x4 feet at a time). Cover with plastic sheeting.
2. Wait 4–24 hours for the paint to fully soften and bubble.
3. Scrape with a wide paint scraper, working with the wood grain. Collect the removed paint in a trash bag.
4. Wipe down with mineral spirits to remove stripper residue.
5. Move to the next section and repeat.

Method 2: Floor Sander (Best for Large Areas)

For an entire room, renting a drum floor sander is the most efficient approach. Start with 36 or 60-grit sandpaper to remove the paint, then progress through 80, 100, and 120-grit to smooth the wood. Use an edge sander for the perimeter. Always sand with the grain. This method removes paint and the top layer of wood simultaneously, revealing fresh wood beneath.

After Stripping: Sand and Finish

After chemical stripping, sand the floor with progressively finer grits from the sandpaper assortment to achieve a smooth, even surface. Vacuum thoroughly and wipe with a tack cloth before applying your chosen floor finish — polyurethane, oil, or wax.

Stripping paint from a wood floor is a significant project but one that can completely transform a room. Chemical stripping preserves the most wood; floor sanding is faster for large areas. Either way, the natural wood revealed beneath is worth every bit of effort.
