Likely causes
- CommonMoisture behind the paintHumidity from showers, cooking, or a leak can push paint off the wall from underneath.
- CommonPoor surface prep before paintingPainting over dust, grease, or glossy surfaces without sanding or priming leads to poor adhesion.
- PossibleIncompatible paint layersOil-based paint under latex, or vice versa without proper priming, can cause peeling.
- PossibleActive water leakPeeling near ceilings or in one spot repeatedly can mean an ongoing leak.
What to do
- Identify if the area is near a known moisture source like a bathroom, kitchen, or exterior wall.
- Scrape away all loose and peeling paint down to a firm edge.
- Sand the exposed area and surrounding edges smooth.
- Address any moisture source first, such as a leak or poor bathroom ventilation.
- Let the wall dry completely before repainting.
- Apply a stain-blocking or bonding primer to the bare area.
- Repaint with a paint rated for the room, such as moisture-resistant paint in bathrooms.

When to call a pro
Call a painter or leak specialist if peeling keeps returning in the same spot, which usually means an unresolved moisture source.
Safety
Use caution
If the home was built before 1978, peeling paint could contain lead; avoid dry sanding or scraping and consider testing before disturbing it.
