Paint Stripping 101: 3 Methods and When to Use Them

Most repaints don't need the old paint stripped. If the existing paint is sound, cleaning, light sanding and priming is enough. Stripping is for paint that's peeling, flaking or built up in thick layers, and the method depends on the surface: scraping and sanding for most jobs, pressure washing for exteriors, and chemical strippers for detailed woodwork.

When paint needs stripping

• The paint is peeling, flaking or blistering, so new paint would fail along with it.
• Layers have built up on trim, doors or cabinets until the details are filled in or doors stick.
• Exterior paint has failed across a large area.

If the old paint is only dull or a color you're tired of, wash it, sand lightly, spot-prime any repairs and paint.

1. Scraping and sanding

Scraping and sanding is the most common way to remove loose paint. A paint scraper takes off what's peeling, then sanding feathers the edges so they don't show through the new coat. A random-orbit sander speeds up larger areas. It's the least expensive method and the most labor. Wear eye protection and a dust mask.

2. Pressure washing for exteriors

Pressure washing is the standard first step before repainting a house exterior. It removes dirt and mildew and blasts away loose, flaking paint. Use a fan tip and keep the nozzle moving, because too much pressure can gouge wood and stucco or force water behind siding. See how we prepare a home's exterior for paint.

3. Chemical paint strippers

Chemical strippers soften paint so it can be scraped off. They work best on detailed trim, doors and furniture, where sanding can't reach. Follow the label closely: work with good ventilation, wear chemical-resistant gloves and eye protection, and clean the surface as directed before priming.

Older homes and lead paint

Homes built before 1978 may have lead paint under newer coats. Test before you scrape, sand or strip. Lead test kits are sold at hardware stores, and the EPA publishes guidance on working with lead paint safely.

After the paint is off

Sand the surface smooth, fill gouges and repair damaged drywall or wood, then prime before painting. Primer seals bare surfaces so the new paint goes on evenly and lasts. See common interior painting problems and how to fix them.
