How to Fix Peeling Paint on Walls

Remove loose paint with a scraper, sand rough areas, prime the surface, then apply two coats of quality paint for a lasting repair.

1. Strip Away the Culprits. Use a paint scraper or putty knife to remove all peeling and loose paint. Work systematically across the affected area, scraping until you reach paint that's firmly adhered to the wall. Don't worry about making the area look perfect - focus on removing anything that could peel off later.
2. Blend the Transition Line. Sand the edges where old paint meets bare wall using 120-grit sandpaper. This creates a smooth transition and helps new paint blend seamlessly. Focus on eliminating any raised edges or rough spots that would show through your final coat.
3. Clear the Canvas Clean. Wipe down the entire area with a damp cloth to remove dust, debris, and any paint chips. Let the wall dry completely before proceeding. Any remaining particles will interfere with paint adhesion and create an uneven finish.
4. Seal the Bare Spots. Use a high-quality primer on any exposed wall surface. This includes areas where you scraped down to bare drywall, wood, or previous paint layers. Apply primer with a brush for detailed work and a roller for larger areas. Let dry according to manufacturer's instructions.
5. Lay the First Layer. Apply your chosen paint using the same technique as the primer - brush for edges and detail work, roller for main areas. Work in sections and maintain a wet edge to avoid lap marks. Don't try to cover everything perfectly in one coat.
6. Perfect the Coverage. Once the first coat is completely dry, apply a second coat for even coverage and durability. Pay special attention to areas that were previously peeling, as these spots may need extra coverage to match the surrounding wall color.
