How to Fix Flaking, Cracking, and Peeling Paint: A Step-by-Step Guide
Flaking, cracking, or peeling paint can make your walls, ceilings, or exterior surfaces look worn and neglected. Whether you're dealing with minor paint chips or significant peeling, addressing the issue promptly is essential for a smooth, long-lasting finish. Here's how to identify the causes of paint failure and fix it step-by-step.
Why Is My Paint Cracking or Peeling?
Before diving into repairs, understanding why paint cracks or peels helps you prevent future issues.
What Causes Paint to Crack?
- Cracking occurs when paint loses adhesion to the surface beneath, often due to:
- Inadequate surface preparation.
- Applying paint too thickly or unevenly.
- Using incompatible paint types (e.g., latex over enamel without proper priming).
Why Is My Paint Cracking When It Dries?
- This happens when paint dries too quickly, often caused by high temperatures, low humidity, or improper application techniques.
How to Stop Paint from Flaking
- Address underlying issues like moisture, dirt, or old paint layers before repainting.
Special Cases: Fixing Peeling in Unique Areas
How to Fix Peeling Paint on Bathroom Walls?
- Moisture is the main culprit. Address ventilation issues and use mildew-resistant primer and paint.
How to Repair Peeling Paint on Drywall?
- Sand the area, fill any divots with drywall compound, and prime before repainting.
How to Fix Peeling Paint on Concrete Floors?
- Remove loose paint, clean the surface, and use an epoxy primer and paint for durability.
How to Fix Paint on Walls Peeling Off in Spots?
- Focus on sanding and spot-priming before repainting those areas.
STEP 1
Remove Chipped or Peeling Paint
Peeling paint must be completely removed for a smooth surface.
How to Remove Chipped Paint
Scrape away loose paint using a putty knife or paint scraper. For larger areas, use a heat gun or paint remover for easier removal. Sand the edges to blend the remaining paint with the exposed surface.
Can You Paint Over Flaking Paint?
No, painting over flaking paint will lead to poor adhesion and more peeling. Always remove it first.
STEP 2
Repair Cracks or Dents
For walls with cracks, holes, or dents, follow these steps:
How to Fix a Crack in the Wall Before Painting
- Clean the crack thoroughly, removing debris and dust.
- Use a high-quality crack and dent filler designed for latex-painted surfaces.
- Smooth the filler with a putty knife and let it dry completely.
- Sand lightly to create a seamless surface.
Best Crack and Dent Filler for Latex Painted Surfaces
Look for fillers compatible with your paint type, like spackling compound or epoxy fillers for deeper cracks.
STEP 3
Prime the Surface
Priming is critical for a durable, professional-looking finish.
Best Primer for Peeling Paint
Use a primer that seals and stabilizes peeling or chalky surfaces.
Best Primer for Peeling Exterior Paint
Exterior-grade primers are designed to withstand outdoor conditions and ensure long-lasting adhesion.
STEP 4
Repaint with High-Quality Paint
Once the surface is smooth and primed, it's time to paint.
Paint That Won't Peel
Choose paints specifically formulated for durability and adhesion, such as Sherwin-Williams Emerald® Exterior Acrylic Latex or Duration® Home Interior Acrylic Latex.
How to Paint Over Chipped Paint
- Apply two thin, even coats of paint, allowing adequate drying time between layers.
- For high-moisture areas like bathrooms, use mold-resistant paint to prevent peeling.
Additional Tips for Success
- How Do You Stabilize Flaking Paint? After scraping, apply a stabilizing primer to seal the remaining paint.
- Can Peeling Paint Be Fixed? Yes, with proper preparation, priming, and painting, peeling paint can be restored effectively.
Preventing Future Peeling
- Ensure surfaces are clean and dry before painting.
- Use high-quality primers and paints appropriate for the material and environment.
- Avoid overloading paint onto surfaces, and allow each coat to dry thoroughly.

WARNING! Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment, such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in US) or contact your local health authority.
