Peeling paint
Tools: scraper, sanding block, putty knife, dust sheets, brush and roller · Materials: filler, bonding primer (or stain-blocking primer for water marks), matching paint
Steps
- Find out why it peeled: moisture behind the wall (bathrooms, exterior walls, below windows) or paint applied over a glossy or dirty surface. Fix the moisture first or it will peel again.
- Scrape all loose paint back to a firm edge, then sand the edges so they feather into the surface.
- Fill any gouges, let the filler dry, and sand smooth.
- Wash the area with sugar soap or a degreaser and let it dry completely.
- Prime the bare patches with a bonding primer, then apply two coats of paint over the whole wall so the sheen matches.
Stop and call a pro if
- the house was built before 1978 (US) or 1980s (EU) and the peeling paint may contain lead — do not sand it dry
- the wall is damp to the touch or paint peels in large sheets from a whole wall
- it is exterior paint above one storey
What a pro does that you can't
A painter tests for lead and removes it safely, treats the moisture source, and repaints whole walls or elevations with the right primer system so the finish lasts.
DIY cost: $20–60 for primer, filler and paint
