How do you get paint off drywall?

Getting paint off of drywall can be a tricky task, but with the right techniques and tools it can be accomplished. In the opening paragraphs, we’ll provide a quick overview of the most effective methods for paint removal from drywall and what items you’ll need. Further detail will then be provided in designated sections throughout the article.

Quick Answers

The most common and effective methods for getting paint off drywall are:

  • Using a paint scraper – Scrapers with sharp blades can peel off layers of paint
  • Chemical paint strippers – Chemical solvents break down paint for easier removal
  • Sanding – Sandpaper or an electric sander removes paint through abrasion
  • Heat gun – Heating up paint makes it easier to scrape off

You’ll need the following supplies:

  • Paint scraper
  • Chemical paint stripper
  • Sandpaper or electric sander
  • Heat gun
  • Paintbrush
  • Putty knife
  • Steel wool
  • Drop cloths
  • Painters tape
  • Safety equipment like gloves and goggles

Assessing the Situation

Before choosing a paint removal method, assess the drywall area to determine the best approach:

  • How many layers of paint are there?
  • What types of paint were used – latex, oil, enamel?
  • How large an area needs paint removed?
  • Is the area textured or smooth drywall?
  • Are you able to fully access the area?

For small areas with only 1-2 layers of latex paint, scraping may be sufficient. For large areas with multiple layers or oil-based paints, chemical strippers or sanding may work better.

Preparing the Workspace

Proper preparation is key to safely removing paint from drywall:

  • Clear the workspace of furniture and belongings
  • Tape plastic sheeting as drop cloths on floor
  • Tape and plastic off any adjacent surfaces not being stripped
  • Open windows and use fans for ventilation
  • Have a ladder and scaffolding ready if working on high areas
  • Wear old clothes and closed toe shoes
  • Don safety goggles, respirator mask, and chemical-resistant gloves

Prepping the space correctly ensures you can work efficiently without worrying about damage to belongings or exposing yourself to debris and fumes.

Paint Scraping

Paint scrapers work well for removing up to 3-5 layers of paint. Here is the process:

  1. Select a paint scraper with a sharp triangular blade. A 4-6 inch scraper is a good all-purpose size.
  2. Place the blade at an angle against the surface and scrape in direction of paint layers.
  3. Apply firm pressure as you scrape to lift up paint edges and peel back paint layers.
  4. Keep scraper blade flush with surface so it doesn’t dig into drywall.
  5. Make horizontal strokes first, then vertical strokes to lift all paint.
  6. Use a putty knife on detailed areas a scraper can’t reach.
  7. Go across entire area until top layers removed, then repeat for next layers.

Scraping works best on flat drywall areas. On textured surfaces, it may just remove paint from the high points.

Chemical Paint Strippers

For removing multiple layers of paint or thick coats of oil-based paint, a chemical paint stripper is very effective:

  1. Select a methylene chloride-based stripper for oil paint or one with benzyl alcohol for latex paint.
  2. Use a paintbrush to generously coat the area with the stripper.
  3. Let stripper sit for specified time based on product directions.
  4. Use putty knife or paint scraper to scrape off the bubbled, loosened paint.
  5. Wipe area clean with mineral spirits to remove stripper residue.
  6. Sand area lightly to smooth and prep for repainting.
  7. Use stripper again on any spots with remaining paint.

Chemical strippers are toxic so protect skin, eyes, and respiratory system. Also ensure proper ventilation.

Sanding

Sanding removes paint through abrasion and can be done either by hand or power sander:

  • Hand-sanding
    • Use medium to coarse grit sandpaper, 80-120 grade.
    • Rub sandpaper back and forth over paint keeping it flush with surface.
    • Apply firm pressure but not enough to remove drywall paper.
    • Wipe away paint dust with dry towel as you go.
    • Replace clogged sandpaper sheets with fresh ones.
  • Power sanding
    • Use random orbital sander for smooth surfaces.
    • Use detail or pad sander for textured or corner areas.
    • Start with 80-grit paper then switch to 120-grit.
    • Keep sander moving constantly to avoid damage.
    • Wipe away dust with dry towel.
    • Clean sander dust bag frequently to optimize efficiency.

Sanding generates lots of fine dust so contain it carefully. Wear respiratory protection.

Heat Gun

A heat gun is a great option for removing many layers of old, thick paint:

  1. Select a heat gun that gets up to at least 1100°F.
  2. Plug in safely away from flammable items and turn on.
  3. Hold 6 inches away from surface and wave back and forth until paint bubbles.
  4. Scrape immediately when bubbling occurs before paint cools.
  5. Keep heating and scraping until multiple layers removed.
  6. Take caution not to scorch or burn drywall.
  7. Allow surface to fully cool then sand smooth.

Heat guns generate extreme heat so wear heavy duty gloves and safety goggles. Have an extinguisher on hand in case of fire.

Final Surface Prep

Once paint removed, the drywall needs proper prep before painting:

  • Fill any gouges with drywall joint compound and let dry.
  • Sand surface with fine 120-150 grit sandpaper.
  • Wipe off all dust with a dry cloth.
  • Spot prime with primer any exposed drywall paper.
  • Allow primer to fully dry.

The surface should now be properly smoothed and ready for a fresh coat of paint.

Safety Tips

Paint removal carries certain risks, so keep these safety tips in mind:

  • Work in a well-ventilated area and wear a respirator.
  • Chemical strippers are toxic so wear gloves and eye protection.
  • Keep an extinguisher nearby when using a heat gun.
  • Contain and properly dispose of lead-based paint chips.
  • Keep drop cloths and plastic sheeting under the workspace.
  • Wear appropriate gloves for chemical or heat protection.
  • Use non-flammable items like plastic putty knives and scrapers.

Conclusion

Removing paint from drywall takes some work, but is definitely doable using scraping, chemical strippers, sanding or heat. With the proper safety precautions and prep, you can strip paint for a smooth surface ready for fresh paint. Just assess the situation, gather the needed supplies, and carefully work the paint loose. In no time, you’ll have that drywall looking brand new again.
