How to Fix Peeling Paint on Interior Walls

Fix peeling paint by scraping off loose areas, sanding smooth, priming bare spots, and applying matching paint in thin, even coats.

1. Strip Loose Paint First. Use a putty knife or paint scraper to carefully remove all loose, flaking, or peeling paint. Work from the edges of damaged areas toward the center, applying steady pressure. Don't dig into the wall surface. Vacuum up debris as you work to keep the area clean.
2. Feather the Edges. Lightly sand all scraped areas with 120-grit sandpaper to create smooth transitions between the existing paint and bare wall. Focus on feathering the edges where good paint meets the scraped areas. Wipe down with a tack cloth to remove all dust.
3. Clean Before Painting. Wash the entire wall section with a damp cloth and mild detergent to remove any grease, dirt, or dust. Allow the wall to dry completely before proceeding. This ensures proper paint adhesion.
4. Prime Bare Spots. Use a high-quality primer designed for your wall material. Apply primer only to areas where you scraped down to bare drywall or previous paint layers. Use a brush for detail work and a small roller for larger areas. Let primer dry according to manufacturer's instructions.
5. Apply Thin, Even Coats. Apply your matching paint in thin, even coats using the same technique as the primer. Start with the repaired areas, then blend outward to cover any visible repair lines. Two thin coats usually work better than one thick coat. Allow proper drying time between coats.
6. Perfect the Finish. Once everything is completely dry, inspect your work in good lighting. Touch up any areas where the repair is still visible or where coverage looks uneven. Feather the edges of touch-ups to blend seamlessly with surrounding paint.
